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 will 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 will still face a minimum 10% ‘baseline’ tariff.
President Trump states 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 will 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 now faces 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.
The US formula for reciprocal tariffs
As we have seen, 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.

As we saw in Part 1, households are seeing a rise in the cost of living, which is set to accelerate. Inflation in the year to January 2022, as measured by the Consumer Prices Index (CPI), was 5.5%, the highest rate for over 30 years, and it is expected to reach more than 7 per cent by April. This has put great pressure on household budgets, with wage rises for most people being below the rate of price inflation. The poor especially have been hard hit, with many struggling to meet soaring energy, food and transport prices and higher rents.
In Part 2 we look at the UK government’s response to the situation, a similar response to that in many other countries.
Effects on government finances
The Chancellor, Rishi Sunak, has stated that the government understands the pressures families are facing with the cost of living. However, rising interest rates mean that it will cost the Treasury considerably more to service the UK’s national debt of more than £2tn.
Interest payments on index-linked debt are calculated using an alternative measure of inflation, the retail prices index (RPI), which is running at 7.8%, considerably higher than anticipated in last October’s Budget. It is now projected that central government spending on debt interest this financial year will come in at around £69bn, some £11bn higher than the £58bn forecast in the October 2021 Budget and £27bn above the £42bn forecast in the March 2021 Budget.
In addition, it is expected that the latest rise in CPI will increase the chances of the Bank of England raising interest rates and thereby further increasing the costs of servicing national debt. If this is the outcome when its Monetary Policy Committee meets next month, then it would be the third successive time interest rates have been raised.
There is also concern that this, in addition to the direct effects of higher costs, will push more firms towards insolvency. It is argued that if government wanted to prevent this, it would need to cut business taxes in order to boost investment and productivity and to allow businesses to provide annual wage rises that are affordable.
Monetary policy
The Bank of England’s traditional response to rising inflation is to raise interest rates, which it has done this twice in the past few months. This means that people who have borrowed money could see their monthly payments go up, especially on mortgages tied to Bank Rate.
An aim of this policy is to make borrowing more expensive resulting in people spending less. As a result, they will buy fewer things, and prices will stop rising as fast. However, when inflation is caused by external forces, this might have a limited effect on prices and would put a further squeeze on household budgets.
Fiscal policy
Alternatively, the government might choose to cut taxes for consumers on items whose prices are rising quickly. It is taking some measures to reduce the impact of energy price rises. For example, the Treasury has announced that it would provide millions of households with up to £350 to help with their rising energy bills and in April the lowest-paid will see the National Living Wage rise by 6.6%, which is higher than the current inflation rate.
The chief economist of the British Chambers of Commerce has said that tightening monetary policy too quickly risks undermining confidence and the wider recovery, arguing that more needs to be done to limit the unprecedented rise in costs facing businesses, including financial support for those struggling with soaring energy bills and delaying April’s national insurance rise.
Conclusion
Rising inflation affects all our living standards. It a global issue with causes beyond government control.
Rising prices together with planned tax increases mean that real average take-home pay is likely to fall over the coming year. The extra energy costs and tax rises will force families to make savings elsewhere, meaning business revenues may fall, and the economic recovery could be negatively impacted.
However, it is those on low incomes that tend to find it hardest to cope with the rising cost of living. Those impacted the most will be faced with difficult decisions over the coming months as they try to cope with falling real incomes. With food price inflation expected to rise further, a likely rise in interest rates and a further increase in the energy price cap in October, these tough decisions are set to get harder for poorest households in the economy.

On 25 November, the UK government published its Spending Review 2020. This gives details of estimated government expenditure for the current financial year, 2020/21, and plans for government expenditure and the likely totals for 2021/22.
The focus of the Review is specifically on the effects of and responses to the coronavirus pandemic. It does not consider the effects of Brexit, with or without a trade deal, or plans for taxation. The Review is based on forecasts by the Office for Budget Responsibility (OBR). Because of the high degree of uncertainty over the spread of the disease and the timing and efficacy of vaccines, the OBR gives three forecast values for most variables – pessimistic, central and optimistic.
According to the central forecast, real GDP is set to decline by 11.3% in 2020, the largest one-year fall since the Great Frost of 1709. The economy is then set to ‘bounce back’ (somewhat), with GDP rising by 5.2% in 2021.
Unemployment will rise from 3.9% in 2019 to a peak of 7.5% in mid-2021, after the furlough scheme and other support for employers is withdrawn.
This blog focuses at the impact on government borrowing and debt and the implications for the future – both the funding of the debt and ways of reducing it.
Soaring government deficits and debt

Government expenditure during the pandemic has risen sharply through measures such as the furlough scheme, the Self-Employment Income Support Scheme and various business loans. This, combined with falling tax revenue, as incomes and consumer expenditure have declined, has led to a rise in public-sector net borrowing (PSNB) from 2.5% of GDP in 2019/20 to a central forecast of 19% for 2020/21 – the largest since World War II. By 2025/26 it is still forecast to be 3.9% of GDP. The figure has also been pushed up by a fall in nominal GDP for 2020/21 (the denominator) by nearly 7%. (Click here for a PowerPoint of the above chart.)
The high levels of PSNB are pushing up public-sector net debt (PSNB). This is forecast to rise from 85.5% of GDP in 2019/20 to 105.2% in 2020/21, peaking at 109.4% in 2023/24.
The exceptionally high deficit and debt levels will mean that the government misses by a very large margin its three borrowing and debt targets set out in the latest (Autumn 2016) ‘Charter for Budget Responsibility‘. These are:
- to reduce cyclically-adjusted public-sector net borrowing to below 2% of GDP by 2020/21;
- for public-sector net debt as a percentage of GDP to be falling in 2020/21;
- for overall borrowing to be zero or in surplus by 2025/26.
But, as the Chancellor said in presenting the Review:
Our health emergency is not yet over. And our economic emergency has only just begun. So our immediate priority is to protect people’s lives and livelihoods.
Putting the public finances on a sustainable footing
Running a large budget deficit in an emergency is an essential policy for dealing with the massive decline in aggregate demand and for supporting those who have, or otherwise would have, lost their jobs. But what of the longer-term implications? What are the options for dealing with the high levels of debt?
1. Raising taxes. This tends to be the preferred approach of those on the left, who want to protect or improve public services. For them, the use of higher progressive taxes, such as income tax, or corporation tax or capital gains tax, are a means of funding such services and of providing support for those on lower incomes. There has been much discussion of the possibility of finding a way of taxing large tech companies, which are able to avoid taxes by declaring very low profits by diverting them to tax havens.
2. Cutting government expenditure. This is the traditional preference of those on the right, who prefer to cut the overall size of the state and thus allow for lower taxes. However, this is difficult to do without cutting vital services.
Indeed, there is pressure to have higher government expenditure over the longer term to finance infrastructure investment – something supported by the Conservative government.
A downside of either of the above is that they squeeze aggregate demand and hence may slow the recovery. There was much discussion after the financial crisis over whether ‘austerity policies’ hindered the recovery and whether they created negative supply-side effects by dampening investment.
3. Accepting higher levels of debt into the longer term. This is a possible response as long as interest rates remain at record low levels. With depressed demand, loose monetary policy may be sustainable over a number of years. Quantitative easing depresses bond yields and makes it cheaper for governments to finance borrowing. Servicing high levels of debt may be quite affordable.
The problem is if inflation begins to rise. Even with lower aggregate demand, if aggregate supply has fallen faster because of bankruptcies and lack of investment, there may be upward pressure on prices. The Bank of England may have to raise interest rates, making it more expensive for the government to service its debts.
Another problem with not reducing the debt is that if another emergency occurs in the future, there will be less scope for further borrowing to support the economy.
4. Higher growth ‘deals’ with the deficit and reduces debt. In this scenario, austerity would be unnecessary. This is the ‘golden’ scenario – for the country to grow its way out of the problem. Higher output and incomes leads to higher tax revenues, and lower unemployment leads to lower expenditure on unemployment benefits. The crucial question is the relationship between aggregate demand and supply. For growth to be sustainable and shrink the debt/GDP ratio, aggregate demand must expand steadily in line with the growth in aggregate supply. The faster aggregate supply can grow, the faster can aggregate demand. In other words, the faster the growth in potential GDP, the faster can be the sustainable rate of growth of actual GDP and the faster can the debt/GDP ratio shrink.
One of the key issues is the degree of economic ‘scarring’ from the pandemic and the associated restrictions on economic activity. The bigger the decline in potential output from the closure of firms and the greater the deskilling of workers who have been laid off, the harder it will be for the economy to recover and the longer high deficits are likely to persist.
Another issue is the lack of labour productivity growth in the UK in recent years. If labour productivity does not increase, this will severely restrict the growth in potential output. Focusing on training and examining incentives, work practices and pay structures are necessary if productivity is to rise significantly. So too is finding ways to encourage firms to increase investment in new technologies.

The Institute of Fiscal Studies (IFS) has just published its annual ‘Green Budget‘. This is, in effect, a pre-Budget report (or a substitute for a government ‘Green Paper’) and is published ahead of the government’s actual Budget.
The Green Budget examines the state of the UK economy, likely economic developments and the implications for macroeconomic policy. This latest Green Budget is written in the context of Brexit and the growing likelihood of a hard Brexit (i.e. a no-deal Brexit). It argues that the outlook for the public finances has deteriorated substantially and that the economy is facing recession if the UK leaves the EU without a deal.
It predicts that:
Government borrowing is set to be over £50 billion next year (2.3% of national income), more than double what the OBR forecast in March. This results mainly from a combination of spending increases, a (welcome) change in the accounting treatment of student loans, a correction to corporation tax revenues and a weakening economy. Borrowing of this level would breach the 2% of national income ceiling imposed by the government’s own fiscal mandate, with which the Chancellor has said he is complying.
A no-deal Brexit would worsen this scenario. The IFS predicts that annual government borrowing would approach £100 billion or 4% of GDP. National debt (public-sector debt) would rise to around 90% of GDP, the highest for over 50 years. This would leave very little scope for the use of fiscal policy to combat the likely recession.
The Chancellor, Sajid Javid, pledged to increase public spending by £13.4bn for 2020/21 in September’s Spending Review. This was to meet the Prime Minister’s pledges on increased spending on police and schools. This should go some way to offset the dampening effect on aggregate demand of a no-deal Brexit. The government has also stated that it wishes to cut various taxes, such as increasing the threshold at which people start paying the 40% rate of income tax from £50 000 to £80 000. But even with a ‘substantial’ fiscal boost, the IFS expects little or no growth for the two years following Brexit.
But can fiscal policy be used over the longer term to offset the downward shock of Brexit, and especially a no-deal Brexit? The problem is that, if the government wishes to prevent government borrowing from soaring, it would then have to start reining in public spending again. Another period of austerity would be likely.
There are many uncertainties in the IFS predictions. The nature of Brexit is the obvious one: deal, no deal, a referendum and a remain outcome – these are all possibilities. But other major uncertainties include business and consumer sentiment. They also include the state of the global economy, which may see a decline in growth if trade wars increase or if monetary easing is ineffective (see the blog: Is looser monetary policy enough to stave off global recession?).

- Why would a hard Brexit reduce UK economic growth?
- To what extent can expansionary fiscal policy stave off the effects of a hard Brexit?
- Does it matter if national debt (public-sector debt) rises to 90% or even 100% of GDP? Explain.
- Find out the levels of national debt as a percentage of GDP of the G7 countries. How has Japan managed to sustain such a high national debt as a percentage of GDP?
- How can an expansionary monetary policy make it easier to finance the public-sector debt?
- How has investment in the UK been affected by the Brexit vote in 2016? Explain.
With the UK parliament in Brexit gridlock, the Labour opposition is calling for a general election. Although its policy over Brexit and a second referendum is causing splits in the party, the Labour party is generally agreed that pubic expenditure on health, education and transport infrastructure needs to increase – that there needs to be an end to fiscal austerity. However, to fund extra public expenditure would require an increase in taxes and/or an increase in government borrowing.
One of the arguments against increasing government borrowing is that it will increase public-sector debt. The desire to get public-sector debt down as a percentage of GDP has been central to both the Coalition and Conservative governments’ economic strategy. Austerity policies have been based on this desire.
But, in the annual presidential address to the American Economics Association, former chief economist at the IMF, Olivier Blanchard, criticised this position. He has argued for several years that cutting government deficits may weaken already weak economies and that this may significantly reduce tax revenues and potential national income, thereby harming recovery and doing long-term economic damage. Indeed, the IMF has criticised excessively tight fiscal policies for this reason.
In his presidential address, he expanded the argument to consider whether an increase in government borrowing will necessarily increase the cost of servicing government debt. When the (nominal) interest rate (r) on government borrowing is below the nominal rate of economic growth (gn), (r < gn), then even if total debt is not reduced, it is likely that the growth in tax revenues will exceed the growth in the cost of servicing the debt. Debt as a proportion of GDP will fall. The forecast nominal growth rate exceeds the 10-year nominal rate on government bonds by 1.3% in the USA, 2.2% in the UK and 1.8% in the eurozone. In fact, with the exception of a short period in the 1980s, nominal growth (gn) has typically exceeded the nominal interest rate on government borrowing (r) for decades.
When r < gn, this then gives scope for increasing government borrowing to fund additional government spending without increasing the debt/GDP ratio. Indeed, if that fiscal expansion increases both actual and potential income, then growth over time could increase, giving even more scope for public investment.
But, of course, that scope is not unlimited.
