Shrinkflation, skimpflation and sneakflation: ways of hiding inflation

Have you noticed that many products in the supermarket seem to be getting smaller or are poorer quality, or that special offers are not as special as they used to be? When you ring customer services, does it seem that you have to wait longer than you used to? Do you now have to pay for extras that used to be free? These are all ways that producers try to pass on cost increases to consumers without rising prices. There are three broad ways in which producers try to hide inflation.

The first is called ‘shrinkflation’. It is defined as having less product in the same package or a smaller package for the same price. For example, reducing the number of chocolates in a tub, reducing the size of a can of beans, jar of coffee or block of butter, reducing the number of sheets in a toilet roll, or the length of a ride in a fairground or portion sizes in a restaurant or takeaway. A 2023 YouGov poll revealed that 75% of UK adults are either ‘very’ or ‘fairly’ concerned about shrinkflation. A similar poll in 2025 showed that this figure had increased to 80%. The product category with the greatest concerns was snack foods (e.g. crisps, confectionery items, nuts, etc.).1

The second form of hidden inflation is called ‘skimpflation’. This is defined as decreasing the quality of a product or service without lowering the price. Examples include cheaper ingredients in food or confectionery, such as using palm oil instead of butter, or reducing the cocoa content in chocolate or the meat content in sausages and pies, or package holidays reducing the quality of meals, or customer service centres or shops reducing the number of staff so that people have to wait longer on the phone or to be served.

The third is called ‘sneakflation’. This is similar to skimpflation but normally refers to reducing what you get when you pay for a service, such as a flight, by now charging for extras, such as luggage or food. Sometimes shrinkflation or skimpflation are seen as subsets of sneakflation.

These practices have had a lot of publicity in recent months, with consumers complaining that they are getting less for their money. Many people see them as a sneaky way of passing on cost increases without raising the price. But the changes are often subtle and difficult for shoppers to spot when they are buying an item. Skimpflation especially is difficult to observe at the time of purchase. It’s only when people consume the product that they think that it doesn’t seem as good as it used to be. Even shrinkflation can be hard to spot if the package size remains the same but there is less in it, such as fewer biscuits in a tin or fewer crisps in a packet. People would have to check the weight or volume, while also knowing what it used to be.

If firms are legitimately passing on costs and are up-front about what they are doing, then most consumers would probably understand it even if they did not like it. It’s when firms do it sneakily that many consumers get upset. Also, firms may do it to increase profit margins – in other words, by reducing the size or quality beyond what is necessary to cover the cost increase.

Does the official rate of inflation take such practices into account?

The answer is that some of the practices are taken into account – especially shrinkflation. The Office for National Statistics (ONS) accounts for shrinkflation by monitoring price changes per unit of weight or volume, rather than just the price. Data collectors track the weight, volume or count of item. When a product’s size is reduced, the ONS records this as a price increase in CPI or CPIH inflation statistics. This is known as a ‘quality adjustment’ process and allows the ONS to isolate price changes from product size changes. As CPI data from the ONS is used by the Bank of England in monitoring its 2% inflation target, it too is incorporating shrinkflation.

ONS quality adjustments are also applied to non-market public services, such as healthcare, education and policing to measure changes in service quality rather than just volume. This allows a more accurate measurement of productivity as it focuses on outcomes and user experience per pound spent rather than just focusing on costs.

Skimpflation is more difficult to monitor. The quality adjustment process may miss some quality changes and hence some skimpflation goes unrecorded. This means that the headline inflation rate might understate the true decline in purchasing power felt by consumers.

How extensive is hidden inflation?

Despite public perception, shrinkflation has a relatively small impact on the headline CPI and CPIH inflation rate in the UK because it is largely confined to certain sectors, such as bread and cereals, personal care products, meat products, and sugar, jams, syrups, chocolate & confectionery. Nevertheless, in these sectors it is particularly prevalent, especially in the packaged foodstuffs and confectionery sector. The latest research by the ONS in 2019 covered the period June 2015 to June 2017 and is shown in the following figure.2

According to research in the USA by Capital One Shopping, some major brands reduced product sizes by over 30% in 2025 without reducing prices, with shrinkflation averaging 14.8% among selected national grocery brands.3 Shrinkflation had been observed by 74% of Americans at their grocery store. Of these, 81% took some kind of action as a result, with 48% abandoning a brand. Nevertheless, across all products, shrinkflation accounts for quite a small percentage of any overall price rises.

A US Government Accountability Office (GAO) report found that shrinkflation accounted for less than 1/10 of a percentage point of the 34.5% increase in overall consumer prices from 2019 to 2024.4 The reason is that the items that were downsized comprised a small percentage of goods and services. Indeed, many goods and services, such as housing, cannot be downsized in the same way that household products can.

Nevertheless, with consumer budgets being squeezed by the inflation that followed the pandemic and the Russian invasion of Ukraine, hidden inflation has become more prevalent in many countries and an increasing concern of consumers.

Fed independence under attack

Donald Trump is keen to lower US interest rates substantially and rapidly in order to provide a boost to the US economy. He is also keen to reduce the cost of living for US citizens and sees lower interest rates as a means of reducing the burden of debt servicing for both consumers and firms alike.

But interest rates are set by the US central bank, the Federal Reserve (the ‘Fed’), which is formally independent from government. This independence is seen as important for providing stability to the US economy and removing monetary policy from short-term political pressures to cut interest rates. Succumbing to political pressures would be likely to create uncertainty and damage long-term stability and growth.

Yet President Trump is pushing the Fed to lower interest rates rapidly and despite three cuts in a row of 0.25 percentage points in the last part of 2025 (see chart below), he thinks this as too little and is annoyed by suggestions that the Fed is unlikely to lower rates again for a while. He has put great pressure on Jerome Powell, the Fed Chair, to go further and faster and has threatened to replace him before his term expires in May this year. He has also made clear that he is likely to appoint someone more willing to cutting rates.

The Federal Reserve headquarters in Washington is currently being renovated. The nine-year project is costing $2.5 billion and is due to be completed next year. President Trump has declared that the project’s costs are excessive and unnecessary.

On 11 January, Federal prosecutors confirmed that they were opening a criminal investigation into Powell, accusing him of lying to Congress in his June 2025 testimony regarding the scope and costs of the renovations.

Powell responded by posting a video in which he claimed that the real reason that he was being threatened with criminal charges was not because of the renovations but because the Fed had ignored President Trump’s pressure and had set interest rates:

based on our best assessment of what will serve the public, rather than following the preferences of the President. This is about whether the Fed will be able to continue to set interest rates based on evidence and economic conditions – or whether, instead, monetary policy will be directed by political pressure or intimidation.

The Fed’s mandate

The Federal Reserve Board decides on monetary policy and then the Federal Open Market Committee (FOMC) decides how to carry it out. It decides on interest rates and asset sales or purchases. The FOMC meets eight times a year.

The Fed is independent of both the President and Congress, and its Chair is generally regarded as having great power in determining the country’s economic policy.

Since 1977, the Fed’s statutory mandate has been to promote the goals of stable prices and maximum employment. Because of the reference to both prices and employment, the mandate is commonly referred to as a ‘dual mandate’. Its inflation target is 2 per cent over the long run with ‘well anchored’ inflationary expectations.

The dual mandate is unlike that of the Bank of England, the European Central Bank, the Bank of Japan and most other central banks, which all have a single key mandate of achieving a target of a 2 per cent annual rate of consumer price inflation over a particular time period.

With a dual mandate, the two objectives may well conflict from time to time. Moreover, changes in monetary policy affect these objectives with a lag and potentially over different time horizons. Hence, an assessment may have to be made of which is the most pressing problem. This does give some leeway in setting interest rates somewhat lower than if there were a single inflation-rate target. Nevertheless, the assessment is in terms of how best to achieve the mandate and not to meet current political goals.

Statement by former Fed Chairs and Governors

On 12 January, three former Chairs of the Federal Reserve (Janet Yellen, Ben Bernanke and Alan Greenspan), four former Treasury Secretaries (Timothy Geithner, Jacob Lew, Henry Paulson and Robert Rubin) and seven other top former economic officials issued the following statement (see Substack link in the Articles section below):

The Federal Reserve’s independence and the public’s perception of that independence are critical for economic performance, including achieving the goals Congress has set for the Federal Reserve of stable prices, maximum employment, and moderate long-term interest rates. The reported criminal inquiry into Federal Reserve Chair Jay Powell is an unprecedented attempt to use prosecutorial attacks to undermine that independence. This is how monetary policy is made in emerging markets with weak institutions, with highly negative consequences for inflation and the functioning of their economies more broadly. It has no place in the United States whose greatest strength is the rule of law, which is at the foundation of our economic success.

Response of investors

What will happen to the dollar, US bond prices, share prices and US inflation, and what will happen to investment, depends on how people respond to the threat to the Fed’s independence. Initially, there was little response from markets, with investors probably concluding that President Trump is unlikely to be able to sway FOMC members. What is more, several Republican lawmakers have begun criticising the Trump administration’s criminal investigation, making it harder for the President to influence Fed decisions.

Even if Powell is replaced, either in the short term or in May, by a chair keen to pursue the Trump agenda, that chair will still be just one of twelve voting members of the FOMC.

Seven are appointed by the President, but serve for staggered 14-year terms. Four have been appointed by President Trump, but the other three were appointed by President Biden, although one – Lisa Cook – is being indicted by the Supreme Court for mortgage fraud, with the hearing scheduled for January 21. She claims that this is a trumped-up charge to provide grounds for removing her from the Fed. If she is removed, President Trump could appoint a replacement minded to cut rates.

The other five members include the President of the New York Fed and four of the eleven other regional Fed Presidents serving in rotation. These four are generally hawkish and would oppose early rate cuts.

Thus it is unlikely that President Trump will succeed in pushing the Fed to lower interest rates earlier than they would have done. For that reason, markets have remained relatively sanguine.

Nevertheless, Donald Trump’s actions could well cause investors to become more worried. Will he try to find other ways to undermine the Fed? Will his actions over Venezuela, Cuba, Greenland and Iran, let alone his policies towards Ukraine and Russia and towards Israel and Gaza, heighten global uncertainty? Will his actions towards Venezuela and his desire to take over Greenland embolden China to attempt to annex Taiwan, and Russia to continue to resist plans to end the war in Ukraine or to make stronger demands?

Such developments could cause investor confidence to wane and for stock markets to fall. Time will tell. I think we need a crystal ball!

The Chancellor’s fiscal dilemma

The UK Chancellor of the Exchequer, Rachel Reeves, will present her annual Budget in late autumn. It will involve some hard economic and political choices. The government would like to spend more money on improving public services but has pledged not to raise taxes ‘on working people’, which is interpreted as not raising the rates of income tax, national insurance for employees and the self-employed, and VAT. What is more, government borrowing is forecast by the OBR to be £118 billion, or nearly 4.0% of GDP, for the the year 2025/26. This is a fall from the 5.1% in 2024/25 and is well below the 15.0% in 2020/21 during the pandemic. But it is significantly above the 2.1% in 2018/19.

The government has pledged to stick to its two fiscal rules. The first is that the day-to-day, or ‘current’, budget (i.e. excluding investment) should be in surplus or in deficit of no more than 0.5 per cent of GDP by 2029/30 (or the third year of the rolling forecast period from the 2026/27 Budget). This allows investment to be funded by borrowing. The second rule is that public-sector net debt, which includes public-sector debt plus pension liabilities minus equity, loans and other financial assets, should be falling by 2029/30 (or the third year of the rolling forecast period from the 2026/27 Budget). The current budget deficit (i.e. excluding borrowing for investment) was forecast by the OBR in March to be 1.2% of GDP for 2025/26 (see Chart 1) and to be a surplus of 0.3% in 2029/30 (£9.9 billion). (Click here for a PowerPoint of the chart.)

The OBR’s March forecasts, therefore, were that the rules would be met with current policies and that the average rate of economic growth would be 1.8% over the next four years.

However, there would be very little room for manoeuvre, and with global political and economic uncertainty, including the effects of tariffs, climate change on harvests and the continuing war in Ukraine, the rate of economic growth might be well below 1.8%.

The March forecasts were based on the assumption that inflation would fall and hence that the Bank of England would reduce interest rates. Global pressure on inflation, however, might result in inflation continuing to be above the Bank of England’s target of 2%. This would mean that interest rates would be slow to fall – if at all. This would dampen growth and make it more expensive for the government to service the public-sector debt, thus making it harder to reduce the public-sector deficit.

A forecast earlier this month by the National Institute for Economic and Social Research (NIESR) (see link below and Chart 2) reflects these problems and paints a gloomier picture than the OBR’s March forecast. The NIESR forecasts that GDP will grow by only 1.3 per cent in 2025, 1.2 per cent in 2026, 1.1% in 2027 and 1.0% in 2028, with the average for 2025 to 2023 being 1.13%. This is the result of high levels of business uncertainty and the effects of tariffs on exports. With no change in policy, the current deficit would be £41.2 billion in the 2029/30 financial year. Inflation would fall somewhat, but would stick at around 2.7% from 2028 to 2030. Net debt would be rising in 2029/30 &ndash but only slightly, from 98.7% to 99.0%. (Click here for a PowerPoint of the chart.)

So what are the policy options open to the government for dealing with a forecast current budget deficit of £41.2 billion (1.17% of GDP)? There are only three broad options.

Increase borrowing

One approach would be to scrap the fiscal rules and accept increased borrowing – at least temporarily. This would avoid tax increases or expenditure cuts. By running a larger budget deficit, this Keynesian approach would also have the effect of increasing aggregate demand and, other things being equal, could lead to a multiplied rise in national income. This in turn would lead to higher tax revenues and thereby result in a smaller increase in borrowing.

There are two big problems with this approach, however.

The first is that it would, over time, increase the public-sector debt and would involve having to spend more each year on servicing that debt. This would leave less tax revenue for current spending or investment. It would also involve having to pay higher interest rates to encourage people to buy the additional new government bonds necessary to finance the increased deficit.

The second problem is that the Chancellor has said that she will stick to the fiscal rules. If she scraps them, if only temporarily, she runs the risk of losing the confidence of investors. This could lead to a run on the pound and even higher interest rates. This was a problem under the short-lived Liz Truss government when the ‘mini’ Budget of September 2022 made unfunded pledges to cut taxes. There was a run on the pound and the Bank of England had to make emergency gilt purchases.

One possibility that might be more acceptable to markets would be to rewrite the investment rule. There could be a requirement on government to invest a certain proportion of GDP (say, 3%) and fund it by borrowing. The supply-side benefits could be faster growth in potential output and higher tax revenue over the longer term, allowing the current deficit rule to be met.

Cut government expenditure

Politicians, especially in opposition, frequently claim that the solution is to cut out public-sector waste. This would allow public expenditure to be cut without cutting services. This, however, is harder than it might seem. There have been frequent efficiency drives in the public sector, but from 1919 to 2023 public-sector productivity fell by an average of 0.97% per year.

Causes include: chronic underinvestment in capital, resulting in outdated equipment and IT systems and crumbling estates; decades of underfunding that have left public services with crumbling estates, outdated equipment and insufficient IT systems; inconsistent, short-term government policy, with frequent changes in government priorities; bureaucratic systems relying on multiple legacy IT systems; workforce challenges, especially in health and social care, with high staff turnover, recruitment difficulties, and a lack of experienced staff.

The current government has launched a Public Sector Productivity Programme. This is a a cross-government initiative to improve productivity across public services. Departments are required to develop productivity plans to invest in schemes designed to achieve cost savings and improve outcomes in areas such as the NHS, police, and justice system. A £1.8 billion fund was announced in March 2024, to support public-sector productivity improvements and digital transformation. Part of this is to be invested in digital services and AI to improve efficiency. According to the ONS, total public-service productivity in the UK grew by 1.0% in the year to Q1 2025; healthcare productivity grew 2.7% over the same period. It remains to be seen whether this growth in productivity will be maintained. Pressure from the public, however, will mean that any gains are likely to be in terms of improved services rather than reduced government expenditure.

Increase taxes

This is always a controversial area. People want better public services but also reduced taxes – at least for themselves! Nevertheless, it is an option seriously being considered by the government. However, if it wants to avoid raising the rates of income tax, national insurance for employees and the self-employed, and VAT, its options are limited. It has also to consider the political ramifications of taking unpopular tax-raising measures. The following are possibilities:

Continue the freeze on income tax bands. They are currently frozen until April 2028. The extra revenue from extending the freeze until April 2030 would be around £7 billion. Although this may be politically more palatable than raising the rate of income tax, the revenue raised will be well short of the amount required and thus other measures will be required. Although some £40 billion will have been raised up to 2028 (which has already been factored in), as inflation falls, so the fiscal drag effect will fall: nominal incomes will need to rise less to achieve any given rise in real incomes.

Cutting tax relief for pensions. Currently, people get income tax relief at their marginal rate on pension contributions made by themselves and their employer up to £60 000 per year or 100% of their earnings, whichever is smaller. When people draw on their pension savings, they pay income tax at their marginal rate, even if the size of their savings has grown from capital gains, interest or dividends. Reducing the limits or restricting relief to the basic rate of tax could make a substantial contribution to increasing government revenue. In 2023/24, pension contribution relief cost the government £52 billion. Restricting relief to the basic rate or cutting the annual limit would make the relief less regressive. In such a case, when people draw on their pension savings, the income tax rate could be limited to the basic rate to avoid double taxation.

Raising the rate of inheritance tax (IHT) or reducing the threshold. Currently, estates worth more than £325 000 are taxed at a marginal rate of 40%. The threshold is frozen until 2029/30 and thus additional revenue will be received by the government as asset prices increase. If the rate is raised above 40%, perhaps in bands, or the threshold were lowered, then this will earn additional revenue. However, the amount will be relatively small compared to the predicted current deficit in 2029/30 of £41 billion. Total IHT revenue in 2022/23 was only 6.7 billion. Also, it is politically dangerous as people could claim that the government was penalising people who had saved in order to help the next generation, who are struggling with high rents or mortgages.

Increased taxes on business. The main rate of corporation tax was raised from 19% to 25% in April 2023 and the employers’ national insurance rate was raised from 13.8% to 15% and the threshold reduced from £9100 to £5000 per year in April 2025. There is little or no scope for raising business taxes without having significant disincentive effects on investment and employment. Also, there is the danger that raising rates might prompt companies to relocate abroad.

Raise fuel and/or other duties. Fuel duties raise approximately £24 billion. They are set to decline gradually with the shift to EVs and more fuel-efficient internal combustion engines. Fuel duty remained unchanged at 57.95p per litre from 2011 to 2022 and then was ‘temporarily’ cut to 52.95p. The rate of 52.95p is set to remain until at least 2026. There is clearly scope here to raise it, if only by the rate of inflation each year. Again, the main problem is a political one that drivers and the motor lobby generally will complain. Other duties include alcohol, tobacco/cigarettes/vaping, high-sugar beverages and gambling. Again, there is scope for raising these. There are two problems here. The first is that these duties are regressive, falling more heavily on poorer people. The second is that high duties can encourage illegal trade in these products.

Raising one of the three major taxes: income tax, employees’ national insurance and VAT. This will involve reneging on the government’s election promises. But perhaps it’s better to bite the bullet and do it sooner rather than later. Six European countries have VAT rates of 21%, three of 22%, three of 23%, two of 24%, four of 25%, one of 25.5% and one of 27%. Each one percentage point rise would raise about 9 billion. A one percentage point rise across all UK income tax rates would raise around £5.8 billion. As far as employees’ national insurance rates are concerned, the Conservative government reduced the main rate twice from 12% to 10% in January 2024 and from 10% to 8% in April 2024. The government could argue that raising it back to, say, 10% would still leave it lower than previously. A rise to 10% would raise around £11 billion.

Conclusion

The choices for the Chancellor are not easy. As the NIESR’s Economic Outlook puts it:

Simply put, the Chancellor cannot simultaneously meet her fiscal rules, fulfil spending commitments, and uphold manifesto promises to avoid tax rises for working people. At least one of these will need to be dropped – she faces an impossible trilemma.

‘Liberation day’: or start of a Trump slump?

On April 2nd, Donald Trump announced sweeping new ‘reciprocal’ tariffs. These would be in addition to 25% tariffs on imports of cars, steel and aluminium already announced and any other tariffs in place on individual countries, such as China. The new tariffs would apply to US imports from every country, except for Canada and Mexico where tariffs had already been imposed.

The new tariffs would depend on the size of the country’s trade in goods surplus with the USA (i.e. the USA’s trade in goods deficit with that country). The bigger the percentage surplus, the bigger the tariff. But, no matter how small a country’s surplus or even if it runs a deficit (i.e. imports more goods from the USA than it sells), it would still face a minimum 10% ‘baseline’ tariff.

President Trump stated that these tariffs are to counter what he claims as unfair trade practices inflicted on the USA. People had been expecting that these tariffs would reflect the tariffs applied by other countries on US goods and possibly also non-tariff barriers, such as the ban on chlorine-washed chicken or hormone-injected beef in the EU and UK. But, by basing them on the size of a country’s trade surplus, this meant imposing them on many countries with which the USA has a free-trade deal with no tariffs at all.

The table gives some examples of the new tariff rates. The largest rates would apply to China and south-east Asian countries, which supply low-priced products, such as clothing, footwear and electronics to the US market. In China’s case, it would a reciprocal tariff rate of 34% plus the previously imposed tariff rate of 20%, giving a massive 54%.

What is more, the ‘de minimis’ exemption will be scrapped for packages sent by private couriers. This had exempted goods of $800 or less sent direct to consumers from China and other countries from companies such as Temu and Alibaba. It is also intended to cut back on packages of synthetic opioids sent from these countries.

Since ‘liberation day’, President Trump has made several changes to these tariff rates. On 9 April he ‘paused’ the implementation of the tariffs above the 10% rate pending trade discussions with individual countries. However, in the case of China, there have been tit-for-tat tariff increases, so that by the end of April, the US tariff rate on Chinese imports was a massive 145% and the Chinese rate on US imports was 125%. The two countries seemed locked in a high-stakes game of chicken.

The US formula for reciprocal tariffs

As we have seen, the proposed (and then paused) reciprocal tariffs do not reflect countries’ tariff rates on the USA. Instead, rates for countries running a trade in goods surplus with the USA (a US trade deficit with these countries) are designed to reflect the size of that surplus as a percentage of their total imports from the USA. The White House has published the following formula.


where:

When the two elasticities are multiplied together this gives 1 and so can be ignored. As there was no previous ‘reciprocal’ tariff, the rise in the reciprocal tariff rate is the actual reciprocal tariff rate. The formula for the reciprocal tariff rate thus becomes the percentage trade surplus of that country with the USA: (exports – imports) / imports, expressed as a percentage. This is then rounded up to the nearest whole number.

President Trump also stated that countries would be given a discount to show US goodwill. This involves halving the rate from the above formula and then rounding up to the nearest whole number.

Take the case of China. China’s exports of goods to the USA in 2024 were $439bn, while its imports of goods from the USA were $144bn, giving China a trade surplus with the USA of $295bn. Expressing this as a percentage of exports gives ($295/$439 × 100)/2 = 33.6%, rounded up to 34%. For the EU, the formula gives ($227bn/$584bn × 100)/2 = 19.4%, rounded up to 20%.

Questioning the value of φ. Even if you accept the formula itself as the basis for imposing tariffs, the value of the second term in the denominator, φ, is likely to be seriously undervalued. The term represents the elasticity of import prices with respect to tariff changes. It shows the proportion of a tariff rise that is passed on to consumers, which is assumed to be just one quarter, with producers bearing the remaining three quarters. In reality, it is highly likely that most of the tariff will get passed on, as it was with the tariffs applied in Donald Trump’s first presidency.

If the value for φ were 1 (i.e. all the tariff passed on to the consumer), the formula would give a ‘reciprocal tariff’ of just one quarter of that with a value of φ of 0.25. The figures in the table above would look very different. If the rates were then still halved, all countries with a tariff below 40% (such as the EU, Japan or India) would instead face just the baseline tariff of 10%. What is more, China’s rate would be reduced from 54% to 30% (the original 20% plus the baseline of 10%). Cambodia’s would be reduced to 13%. Even if the halving discount were no longer applied, the rates would still be only half of those shown in the table (and 37% for China).

Are the tariffs justified?

Even if a correct value of φ were used, a percentage trade surplus is a poor way of measuring the protection used by a country. Many countries running a trade surplus with the USA are low-income countries with low labour costs. They have a comparative advantage in labour-intensive goods. That allows such goods to be purchased at low cost by Americans. Their trade surplus may not be a reflection of protection at all.

Also, if protection is to be used to reflect the trade imbalance with each country, then why impose a 10% baseline on countries, like the UK, with which the USA has a trade surplus? By the Trump administration’s logic, it ought to be subsidising UK imports or accepting of UK tariffs on imports of US goods.

But President Trump also wants to address the USA’s overall trade deficit. The US balance of trade in goods deficit was $1063bn in 2023 (the latest year for a full set of figures). But the overall balance of payments must balance. There were thus surpluses elsewhere on the balance of payments account (and some other deficits). There was a surplus on the services account of $278bn and on the financial account of $924bn. In other words, inward investment to the USA (both direct and portfolio) and the acquisition of dollars by other countries as a reserve asset were very large and helped to drive up the exchange rate. This made US goods less competitive and imports relatively cheaper.

The USA has a large national debt of some $36 trillion of which some $9 trillion is owed to foreign investors (people, institutions or countries). Servicing the debt pushes up US interest rates. This helps to maintain a high exchange rate, thereby making imports cheaper and worsening the trade deficit. The fiscal burden of servicing the debt also crowds out US government expenditure on items such as defence, education, law and order and infrastructure. President Trump hopes that tariffs will bring in additional revenue to help finance the deficit.

Effects on the USA

If the tariffs reduce spending on imports and if other countries do not retaliate, then the US balance of trade should improve. However, a tariff is effectively a tax on imported goods. It is charged to the importing company not to the manufacturer abroad. As we saw in the context of the false value for φ, most of the tariff will be passed on to American consumers. Theoretically the incidence of the tariff is shared between the supplier and the purchaser, but in practice, most of the higher cost to the importer will be passed on to the consumer. As with other taxes, the effect is to transfer money from the consumer to the government, making people poorer but giving the government extra revenue. This revenue will be dollars, not foreign currency.

As some of the biggest price rises will be for cheap manufactured products, such as imports from China, and various staple foodstuffs, the effects could be felt disproportionately by the poor. Higher import prices will allow domestic producers competing with these imports to raise their prices too. The tariffs are thus likely to be inflationary. But because the inflation would be the result of higher costs, not higher demand, this could lead to recession as real incomes fell.

American resources will be diverted by the tariffs from sectors in which the USA has a comparative advantage, such as advanced manufactured goods and services, to more basic products. Tariffs on cheap imports will make domestic versions of these products more profitable: even though they are more costly to produce, they will be sold at a higher price.

The tariffs will also directly affect goods produced by US companies. The reason is that many use complex supply chains involving parts produced abroad. Take the case of Apple. Even though it is an American company which designs its products in California, the company sources parts from several Asian countries and has factories in Vietnam, China, India, and Thailand. These components will face tariffs and thus directly affect the price of iPhones, iPads, MacBooks, etc. Similarly affected are other US tech hardware manufacturers, US car manufactures, clothing and footwear producers, such as The Gap and Nike, and home goods producers.

Monetary policy response. How the Fed would respond is not clear. Higher inflation and lower growth, or even a recession, produces what is known as ‘stagflation’: inflation combined with stagnation. Many countries experienced stagflation following the Russian invasion of Ukraine, when higher commodity prices led to soaring inflation and economic slowdown. There was a cost-of-living crisis.

If a central bank has a simple mandate of keeping inflation to a target, higher inflation would be likely to lead to higher interest rates, making recession even more likely. It is the inflation of the two elements of stagflation (inflation and stagnation) that is addressed. The recession is thus likely to be deepened by monetary policy. But as the Fed has a dual mandate of controlling inflation but also of maximising employment, it may choose not to raise interest rates, or even to lower them, to get the optimum balance between these two targets.

If other countries retaliate by themselves raising tariffs on US exports and/or if consumers boycott American goods and services, this will further reduce incomes in the USA. Just two days after ‘liberation day’, China retaliated against America’s 34% additional tariff on Chinese imports by imposing its own 34% tariff on US imports to China.

A trade war will make the world poorer, especially the USA. Investors know this. In the two days following ‘liberation day’, stock markets around the world fell sharply and especially in the USA. The Dow Jones was down 9.3% and the tech-heavy Nasdaq Composite was down 11.4%.

Effects on the rest of the world

The effects of the tariffs on other countries will obviously depend on the tariff rate. The countries facing the largest tariffs are some of the poorest countries which supply the USA with simple labour-intensive products, such as garments, footwear, food and minerals. This could have a severe effect on their economies and cause rapidly increasing poverty and hardship.

If countries retaliate, then this will raise prices of their imports from the USA and hurt their own domestic consumers. This will fuel inflation and push the more seriously affected countries into recession.

If the USA retaliates to this retaliation, thereby further escalating the trade war, the effects could be very serious. The world could be pushed into a deep recession. The benefits of trade, where all countries can gain by specialising in producing goods with low opportunity costs and importing those with high domestic opportunity costs, would be seriously eroded.

What President Trump hopes is that the tariffs will put him in a strong negotiating position. He could offer to reduce or scrap the tariffs on a particular country in exchange for something he wants. An example would be the offer to scrap or reduce the baseline 10% tariff on UK exports and/or the 25% tariff on UK exports of cars, steel and aluminium. This could be in exchange for the UK allowing the importation of US chlorinated chicken or abolishing the digital services tax. This was introduced in 2020 and is a 2% levy on tech firms, including big US firms such as Amazon, Alphabet (Google), Meta and X.

It will be fascinating but worrying to see how the politics of the trade war play out.

Crude oil – a volatile market

The market for crude oil is usually a volatile one. Indeed, in the last few months, the market has seen prices rise and fall due to various supply and demand influences. Crude oil is coined the ‘King of Commodities’ due to the impact it has on consumers, producers and both the micro and macro economy. The price of crude oil affects everything from the cost of producing plastics, transportation, and food at the supermarket.

This makes the market for crude oil an economic powerhouse which is closely watched by businesses, traders, and governments. To gain a full understanding of the movements in this market, it is important to identify how demand and supply affect the price of crude oil.

What influences the demand and supply of crude oil?

The law of demand and supply states that if demand increases, prices will rise, and if supply increases, prices will fall. This is exactly what happens in the market for crude oil. The consumer side of the market consists of various companies and hundreds of millions of people. The producer side of the market is made up of oil-producing countries. Collectively, both consumers and producers influence the market price.

However, the demand and supply of crude oil, and therefore the price, is also affected by global economic conditions and geopolitical tensions. What happens in the world impacts the price of oil, especially since a large proportion of the world’s biggest oil producers are in politically unstable areas.

Over the past five years, global events have had a major impact on the price of oil. The economic conditions created by the impact of the COVID pandemic saw prices plummet from around $55 per barrel just before the pandemic in February 2020 to around $15 per barrel in April 2020. By mid-2021 they had recovered to around $75 per barrel. Then, in the aftermath of Russia’s invasion of Ukraine in February 2022, the price surged to reach $133 in June 2022. More recently, geopolitical tensions in the Middle East and concerns about China’s economic outlook have intensified concerns about the future direction of the market. (Click here for a PowerPoint of the chart.)

Geopolitical tensions

In the first week of October 2024, the price of crude oil rose by almost 10% to around $78 per barrel as the conflict in the Middle East intensified. It unfortunately comes at a time when many countries are starting to recover from the rise in oil prices caused by the pandemic and the war in Ukraine. Any increase in prices will affect the price that consumers pay to fill up their vehicles with fuel, just when prices of diesel and petrol had reached their lowest level for three years.

The Governor of the Bank of England, Andrew Bailey, has said that the Bank is monitoring developments in the Middle East ‘extremely closely’, as the conflict has the potential to have serious impacts in the UK. The Bank of England will therefore be watching for any movement in oil prices that could fuel inflation.

The main concerns stem from further escalation in the conflict between Israel and the Iran-backed armed group, Hezbollah, in Lebanon. If Israel decides to attack Iran’s oil sector, this is likely to cause a sharp rise in the price of oil. Iran is the world’s seventh largest oil exporter and exports over half of its production to China. If the oilfields of a medium-sized supplier, like Iran, were attacked, this could threaten general inflation in the UK, which could in turn influence any decision by the Bank of England to lower interest rates next month.

Supply deficits

This week (2nd week of October 2024) saw the price of crude oil surge above $81 per barrel to hit its highest level since August. This rise means that prices increased by 12% in a week. However, this surge in price also means that prices rose by almost 21% between the start September and the start of October alone. Yet it was only in early September when crude oil hit a year-to-date low, highlighting the volatility in the market.

As the Middle-East war enters a new and more energy-related phase, the loss of Iranian oil would leave the market in a supply deficit. The law of supply implies that such a deficit would lead to an increase in prices. This also comes at a time when the US Strategic Petroleum Reserve has also been depleted, causing further concerns about global oil supply.

However, the biggest and most significant impact would be a disruption to flows through the Strait of Hormuz. This is a relatively narrow channel at the east end of the Persian Gulf through which a huge amount of oil tanker traffic passes – about a third of total seaborne-traded oil. It is therefore known as the world’s most important oil transit chokepoint. The risk that escalation could block the Strait of Hormuz could technically see a halt in about a fifth of the world’s oil supply. This would include exports from big Gulf producers, including Saudi Arabia, UAE, Kuwait and Iraq. In a worst-case scenario of a full closure of the Strait, a barrel of oil could very quickly rise to well above $100.

Disruption to shipments would also lead to higher gas prices and therefore lead to a rise in household gas and electricity bills. As with oil, gas prices filter down supply chains, affecting the cost of virtually all goods, resulting in a further rise in the cost of living. With energy bills in the UK having already risen by 10% for this winter, an escalation to the conflict could see prices rise further still.

China’s economic outlook


Despite the concern for the future supply of oil, there is also a need to consider how the demand for oil could impact price changes in the market. The price of oil declined on 14 October 2024 in light of concerns over China’s struggling economy. As China is the world’s largest importer of crude oil, there are emerging fears about the potential limits on fuel demand. This fall in price reversed increases made the previous week as investors become concerned about worsening deflationary pressures in China.

Any reduced demand from China could indicate an oversupply of crude oil and therefore potential price declines. Official data from China reveal a sharp year-on-year drop in the producer price index of 2.8% – the fastest decline in six months. These disappointing results have stirred uncertainty about the Chinese government’s economic stimulus plans. Prices could fall further if there are continuing doubts about the government’s ability to implement effective fiscal measures to promote consumer spending and, in turn, economic growth.

As a result of the 2% price fall in oil prices on 14 October, OPEC (the Organization of the Petroleum Exporting Countries) has lowered its 2024 and 2025 global oil demand growth. This negative news outweighed market concerns over the possibility that an Israeli response to Iran’s missile attack could disrupt oil production.

What is the future for oil prices?

It is expected that the market for oil will remain a volatile one. Indeed, the current uncertainties around the globe only highlight this. It is never a simple task to predict what will happen in a market that is influenced by so many global factors, and the current global landscape only adds to the complexity.

There’s a wide spectrum of predictions about what could come next in the market for crude oil. Given the changes in the first two weeks of October alone, supply and demand factors from separate parts of the globe have made the future of oil prices particularly uncertain. Callum Macpherson, head of commodities at Investec, stated in early October that ‘there is really no way of telling where we will be this time next week’ (see the first BBC News article linked below).

Despite the predominately negative outlook, this is all based on potential scenarios. Caroline Bain, chief commodities economist at Capital Economics suggests that if the ‘worst-case scenario’ of further escalation in the Middle East conflict does not materialise, oil prices are likely to ‘ease back quite quickly’. Even if Iran’s supplies were disrupted, China could turn to Russia for its oil. Bain says that there is ‘more than enough capacity’ globally to cover the gap if Iranian production is lost. However, this does then raise the question of where the loyalty of Saudi Arabia, the world’s second largest oil producer, lies and whether it will increase or restrict further production.

What is certain is that the market for crude oil will continue to be a market that is closely observed. It doesn’t take much change in global activity for prices to move. Therefore, in the current political and macroeconomic environment, the coming weeks and months will be critical in determining oil prices and, in turn, their economic effects.
