A single European market in banking

Large European banks call for further integration, but is it in consumers’ interests?

Those of a certain age may remember the fanfare which heralded the introduction of the Single European market (SEM) on 1 January 1993. It promised the removal of internal barriers to the movement of goods, services, capital and people. One sector that was noticeably absent from the single market, however, was banking.

Moves towards banking union only started after the global financial crisis in 2008. However, as a report published on the 2 September 2025 by the Association of Financial Markets in Europe (AFME) highlights, the institutional frameworks of banking in the EU are still deeply fragmented – the promised integration through the European Banking Union (EBU) is still incomplete. This has put European banks at a competitive disadvantage in global markets compared with rivals from the USA and Asia, thereby reducing their profitability and growth prospects. The report called on the European Central Bank (ECB) and national regulatory authorities to remove hurdles to cross-border banking services in the EU. This would enhance the strategic position of European banks.

In this blog we will trace the development of the EBU and analyse the current state of integration. We discuss the AFME proposals for achieving greater integration and highlight their benefits for large banks. We also analyse the barriers which limit full integration and examine the risks that retail customers might see few benefits from the proposed changes.

What is meant by European Banking Union (EBU)?

The 1993 Single European Market (SEM) in goods and services removed internal barriers to the movement of goods, services, capital and people within the EU. As part of this, there were harmonised standards and regulations for goods and services, no capital controls, mutual recognition of professional qualifications and common regulations on consumer protection, product safety, environmental protection and labour rights.

This integration of previously restricted domestic markets was designed to boost economic growth, employment and competitiveness by increasing trade and investment flows. Offering consumers greater choice would expose firms to greater competition. This would drive down prices and encourage greater efficiency and innovation. It has generally achieved these goals across many industries.

However, banking was excluded from integration. The 1985 White Paper, Completing the Internal Market, proposed the liberalisation of financial services, but banking remained regulated at the national level. This was influenced by interrelated economic, political and institutional forces, national sovereignty and political sensitivities, fragmented regulation and concerns about risk.

Even as the EU moved towards economic and monetary union (EMU) during the 1990s, there was no discussion of integration for the banking industry. However, that changed following the 2008 financial crisis and 2011 eurozone crisis. Both episodes exposed vulnerabilities in the EU banking system which required taxpayer support. It was proposed that deeper integration of the banking sector would ensure its stability and resilience. This stimulated moves towards European Banking Union (EBU), starting with the European Council agreeing its creation in 2012. There are three institutional pillars to the Union:

  1. The Single Supervisory Mechanism (2014) for systemically important financial institutions (SIFIs) ensures consistent oversight. SIFIs are banks with over €30 billion of liabilities or 20% of national GDP.
  2. The Single Resolution Mechanism (2016) manages the orderly resolution of failing banks with minimal costs to taxpayers. There is a central board for resolution decisions and a fund financed by the banking industry to support resolution actions.
  3. A European Deposit Insurance Scheme (still under negotiation) is proposed to protect depositors uniformly across the banking union against bank default.


The Union is intended to operate under a harmonised set of EU laws, known as the ‘Single Rulebook’, which includes implementing the BASEL III capital requirements, regulating national deposit insurance and setting rules for managing failing banks.

What is the state of integration at present?

Moves towards European Banking Union (EBU) have contributed to enhancing the resilience of the European banking system. This was one of its major objectives. European banks are much more secure having increased capital and liquidity levels, reduced credit risks and become less reliant on state-aid. They are also less profitable.

The AFME report points to remaining gaps in Banking Union which raise the cost for banks offering cross-border retail banking within the EU and limit the incentive to do so. The report identifies four such gaps.

1. Ring fencing.  Although there is a single supervisory mechanism for large systemically important institutions, since the financial crisis national regulators have implemented ‘ring-fencing’. This aims to protect retail banking activities from riskier investment banking. Ring-fencing retains liquidity, dividends and other bank assets within national borders to protect their retail banking sectors from contagion. The ECB estimates €225 billion of capital and €250 billion of liquidity is trapped by such national restrictions. Further, unharmonized and unpredictable use of capital buffers adds complexity for capital management at a multinational level. This particularly impacts large institutions. Banks’ cross-border activities are impeded since they are restricted in the way they can use capital and liquidity across the bloc.

The report argues that the stringent requirements of the ECB and the multiple layers of macroprudential requirements imposed at national level have led to an unnecessarily high level of capital. This disadvantages large European banks compared to their international competitors.

2. Impediments to cross-border M&As in banking within the EU.  This is due to cumbersome authorisation processes, involving multiple authorities at both national and supra-national level. Further, national authorities may interfere in the process of M&As in a bid to prevent domestic banks being acquired by ones from other parts of the EU. A recent example is UniCredit’s bid for Germany’s Commerzbank, which the German government opposes. These characteristics restrict opportunities for consolidation and efficiency gains for European banks.

The AFME report estimates that once eurozone banks grow beyond €450 billion in total assets, they suffer from negative synergies putting them at a competitive disadvantage to global competitors. Indeed, US banks are able to leverage scale economies from their domestic market to enter large EU markets. An example is JP Morgan’s entry into multiple EU markets through its Chase brand.

3. Contributions to the Single Resolution Fund (SRF) are complex and lack transparency.  This makes it difficult for banks to predict future commitments. The fund itself and its target level were determined at a time when banks had low buffers. Since then, European banks have raised their loss absorbing capacity and the AFME report proposes that further increases in contributions to the fund need to be carefully considered and reviewed.

4. The Deposit Guarantee Scheme remains unimplemented and there are still differences in national schemes.  This situation creates uncertainty for banks, which would like the European scheme for large systemically important institutions to be implemented fully.

These AFME proposals focus on the aspects of banking union which benefit large European institutions in their strategic competition with global rivals. These aspects would create ‘European’ banks as opposed to ‘national’ ones. This would give them the scale to be ‘champions’ in global competition. In particular, the large banks want lower capital requirements and the relaxation of national ring-fencing for retail banking to allow them greater freedom to achieve scale and scope economies across the bloc.

To what extent this will benefit retail customers, however, is debateable.

Will retail banking customers benefit?

Retail banking across Europe remains deeply fragmented, with significant price differentials from country to country. The following table illustrates pricing differentials for two retail products – loans and mortgages – across a sample of EU countries for July 2025.


The data show a range of average interest rates offered across the countries with a range of 5.03% for loans to households and 0.92% for new mortgages. These price differentials reflect a broad array of factors, not least the different institutional legal and risk characteristics of the national markets. They also reflect varying degrees of competition and the lack of cross-border trade in retail banking products. Retail banking remains a largely domestic industry within the EU. Cross-border banking services remain a marginal activity with non-domestic retail deposits rising by just 0.5% and non-domestic retail loans rising by just 0.3% between 2016 and 2024.

There are both natural and policy-induced barriers, which means that retail banking will remain largely segmented by nation.

On the demand-side, retail banking is largely a relational rather than a transactional service, with consumption taking place over a long time-period with significant financial risks attached. Even with deposit insurance and a lender of last resort (the central bank), consumers exhibit significant loss aversion in their use of retail banking services. Consequently, trust and confidence are important characteristics for consumers and that means they are likely to prefer to use familiar domestic institutions.

Further, perceptions about switching costs mean that consumers are reluctant to change suppliers. Such costs are exacerbated by language, cultural and legal differences between European countries, which can make the perceived costs of banking beyond national boundaries prohibitively expensive and create a preference for local institutions.

Consumer preferences can also create idiosyncratic market structures for retail banking services in particular countries. For instance, in several countries across the EU, notably Germany, mutualised credit unions account for significant shares of retail banking. This may limit the potential for foreign banks to penetrate Europe’s largest market.

There are also policy-induced obstacles to cross-border retail banking which operate on the demand-side. These include discriminatory tax treatment of foreign financial services which deters their purchase by consumers. Further, there are still eight different currencies used in the EU across the 27 member states (Denmark, Poland and Sweden are three significant examples). This creates costs and risks associated with currency exchange for consumers that may deter their use of cross-border deposits and loans. The full adoption of a single currency across the EU seems a long way off, which will limit the potential for a single banking market, particularly in the retail segment.

Retail banking as a public utility

Some argue that retail banking is a public utility and should be regulated as such. It has a simple business model, taking deposits, making payments and making loans. Like other utilities, such as water and energy, retail banking is an essential service for the smooth functioning of the economy and society. Like other utilities, bank failures create severe problems for the economy and society.

Since the financial crisis, stability in retail banking has been much more highly valued. In the period preceding the crisis, banks had used retail deposits to cross-subsidise their risky investment banking. The bank failures that resulted from this had severe economic consequences. The danger today is that by relaxing capital and liquidity restrictions too much, large banks may once again engage in risky behaviour, subsidised by retail banking – for example, by engaging in cross-border M&As. These may benefit their shareholders but provide little benefit to retail customers.

Further, allowing these large banks freedom to move funds around the bloc may lead to capital being concentrated in the most profitable markets, leaving less profitable markets / countries underserved. Retail banking, as a public utility, should be required to provide services there.

Who ultimately benefits?

The integration of banking services in the EU has progressed since the financial crisis, producing a more resilient system. However, there are features of retail banking which mean that integration which benefits consumers may be difficult to achieve.

Addressing the policy gaps identified by the AFME report may benefit large European banks by facilitating the scale economies to make them competitive internationally. However, until consumers are prepared, or able, to source banking services beyond national borders, they will see little benefit from European Banking Union (EBU) through lower prices and/or better service. The nature of retail banking in the EU suggests that this is unlikely any time soon.

Furthermore, since retail banking exhibits features of a public utility, regulators need to be wary of permitting the type of behaviour by large institutions which creates dangerous systemic risk. The worry is that, in the drive to create ‘European Champions’ in banking, regulators ignore the potential impact on retail customers.

Gold: why the world’s oldest safe haven is back in the spotlight

The gold market has become one of the most talked-about commodity markets in 2025, with prices reaching record highs. This is largely due to increased demand from investors, who see gold as a ‘safe haven’ during times of economic and political uncertainty. Central banks are also buying more gold as a way to reduce their reliance on currencies like the US dollar. With many analysts predicting prices could reach over $4000 per ounce in the next year, the gold market is showcasing how supply and demand, confidence, and global events can all influence a commodity market.

The commodities market is where basic agricultural products, raw materials and metals, such as gold, are bought and sold, often in large quantities and across global exchanges. Commodities are typically traded either in their physical form (like gold bars) at current market prices (spot prices) or through financial contracts, where investors buy or sell in futures markets. These are where a price is agreed today to buy or sell on a specific future date.

As with other commodities, the price of gold is determined by supply and demand. Demand for gold typically rises during times of economic uncertainty as investors want a safer store of value. This results in an increase in its price. Supply and demand, and hence price, also respond to other factors, including interest rates, currency movements, economic growth and growth prospects, and geopolitical events.

Record high prices

This year, the gold market has seen a remarkable rally, with the price of gold hitting a record high. Demand for the precious metal has resulted in spot prices surging over 35% to date (see the chart: click here for a PowerPoint). Rising prices earlier this year have been attributed to the US President, Donald Trump, announcing wide-ranging tariffs which have upset global trade. On 2 September, the spot gold price hit $3508.50 per ounce, continuing its upwards trend.

The price has also been lifted by expectations that the Federal Reserve (the US central bank) will cut its key interest rate, making gold an even more attractive prospect for investors. If the Federal Reserve cuts interest rates, the price of gold usually increases. This is because gold does not pay any interest or yield, so when interest rates are high, investors can earn better returns from alternatives, such as savings accounts or bonds. However, when interest rates fall, those returns become less attractive, making gold relatively more appealing.

Lower interest rates also tend to weaken the US dollar, which makes gold cheaper for foreign buyers, increasing global demand. Since gold is priced in dollars, a weaker dollar usually leads to higher gold prices.

Additionally, interest rate cuts are often a response to economic problems or uncertainty. As gold is viewed as a safer asset for investors during times of economic uncertainty, investors will typically increase their demand.

Unlike the market for currencies or shares, gold doesn’t rely on the performance of a government or company. This makes it attractive when people are worried about things like inflation, recession, war or stock market crashes. Gold is thus seen as a ‘safe haven’.

Gold and the Federal Reserve

The rise in the price of gold by more than a third this year can be linked to the US election last year, according to the director of research at BullionVault (see the BBC article below). Attitudes of the Trump administration towards the Federal Reserve have created concerns among investors. Fears that the US administration could erode the independence of the world’s most important central bank have fuelled the latest flows into the metal, which is traditionally viewed as a hedge against inflation.

According to the BBC article, Derren Nathan from Hargreaves Lansdown claims that it is Trump’s ‘attempts to undermine the independence of the Federal Reserve Bank’ that were ‘driving renewed interest in safe haven assets, including gold’. Investors are concerned that a politicised Fed would be more inclined to cut interest rates than would otherwise be the case, sending long-term inflation expectations higher.

This could lead to fears that future interest rates would then be pushed higher. This would increase the yields on longer-term government bonds by pushing down their price, as investors demand higher compensation for the increased risk of higher future interest rates reducing the value of their fixed-rate investments. This would force the US Treasury to pay higher interest on new bonds, making it more expensive to service US government debt.

Expected price rises for 2026

As we saw above, it is predicted that the price of gold will rise to $4000 per ounce next year. However, if the market sees investors move away from dollar assets, such as US Treasuries, the price increases would be even higher. Daan Struyven, co-head of global commodities research at Goldman Sachs explains ‘If 1 per cent of the privately owned US Treasury market were to flow to gold, the gold price would rise to nearly $5000 per troy ounce’ (see Financial Times article below).

If the Federal Reserve does come under political pressure, it could affect the stability of the US economy and beyond. When gold prices rise sharply, demand usually falls in countries like China and India, which are the world’s largest buyers of gold jewellery. However, in 2025, this trend has changed. Instead of reducing their gold purchases, people in these countries have started buying investment gold, such as bars and coins, showing a shift in consumer behaviour from jewellery to investment assets.

At the same time, global events are also influencing the gold market. Suki Cooper, a metals analyst at Standard Chartered, said that events like Russia’s invasion of Ukraine have added to political uncertainty, which tends to increase demand for gold as a safe-haven asset. She also highlighted how changes in international trade policies have disrupted supply chains and contributed to higher inflation, both of which have made gold more attractive to investors. Additionally, a weaker US dollar earlier in the year made gold cheaper for buyers using other currencies, which boosted global demand even further.

Conclusion

Although the gold market is expected to remain strong over the next six months, some uncertainty remains. Many analysts predict that gold prices will stay high or even increase further, especially if interest rates in the US are cut as expected. Continued global instability, is also likely to keep demand for gold as a safe haven high. At the same time, if inflation stays elevated or trade disruptions continue, more investors may turn to gold to protect their wealth.

However, if economic conditions stabilise or interest rates rise again, gold demand could fall slightly, leading to a potential dip in prices. Overall, the outlook for gold remains positive, but sensitive to changes in global economic and political events.

Rising global uncertainty and its effects

In a blog in October 2024, we looked at global uncertainty and how it can be captured in a World Uncertainty Index. The blog stated that ‘We continue to live through incredibly turbulent times. In the past decade or so we have experienced a global financial crisis, a global health emergency, seen the UK’s departure from the European Union, and witnessed increasing levels of geopolitical tension and conflict’.

Since then, Donald Trump has been elected for a second term and has introduced sweeping tariffs. What is more, the tariffs announced on so-called ‘Liberation Day‘ have not remained fixed, but have fluctuated with negotiations and threatened retaliation. The resulting uncertainty makes it very hard for businesses to plan and many have been unwilling to commit to investment decisions. The uncertainty has been compounded by geopolitical events, such as the continuing war in Ukraine, the war in Gaza and the June 13 Israeli attack on Iran.

The World Uncertainty Index (WUI) tracks uncertainty around the world by applying a form of text mining known as ‘term frequency’ to the country reports produced by the Economist Intelligence Unit (EIU). The words searched for are ‘uncertain’, ‘uncertainty’ and ‘uncertainties’ and the number of times they occur as percentage of the total words is recorded. To produce the WUI this figure is then multiplied by 1m. A higher WUI number indicates a greater level of uncertainty.

The monthly global average WUI is shown in Chart 1 (click here for a PowerPoint). It is based on 71 countries. Since 2008 the WUI has averaged a little over 23 000: i.e. 2.3 per cent of the text in EIU reports contains the word ‘uncertainty’ or a close variant. In May 2025, it was almost 79 000 – the highest since the index was first complied in 2008. The previous highest was in March 2020, at the start of the COVID-19 outbreak, when the index rose to just over 56 000.

The second chart shows the World Trade Uncertainty Index (WTUI), published on the same site as the WUI (click here for a PowerPoint). The method adopted in its construction therefore mirrors that for the WUI but counts the number of times in EIU country reports ‘uncertainty’ is mentioned within proximity to a word related to trade, such as ‘protectionism’, ‘NAFTA’, ‘tariff’, ‘trade’, ‘UNCTAD’ or ‘WTO.’

The chart shows that in May 2025, the WTUI had risen to just over 23 000 – the second highest since December 2019, when President Trump imposed a new round of tariffs on Chinese imports and announced that he would restore steel tariffs on Brazil and Argentina. Since 2008, the WTUI has averaged just 2228.

It remains to be seen whether more stability in trade relations and geopolitics will allow WUI and WUTI to decline once more, or whether greater instability will simply lead to greater uncertainty, with damaging consequences for investment and also for consumption and employment.

‘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.

Investment set to fall as business is baffled by Trump

Economic growth is closely linked to investment. In the short term, there is a demand-side effect: higher investment, by increasing aggregate demand, creates a multiplier effect. GDP rises and unemployment falls. Over the longer term, higher net investment causes a supply-side effect: industrial capacity and potential output rise. This will be from both the greater quantity of capital and, if new investment incorporates superior technology, from a greater productivity of capital.

One of the biggest determinants of investment is certainty about the future: certainty allows businesses to plan investment. Uncertainty, by contrast, is likely to dampen investment. Investment is for future output and if the future is unknown, why undertake costly investment? After all, the cost of investment is generally recouped over several months or year, not immediately. Uncertainty thus increases the risks of investment.

There is currently great uncertainty in the USA and its trading partners. The frequent changes in policy by President Trump are causing a fall in confidence and consequently a fall in investment. The past few weeks have seen large cuts in US government expenditure as his administration seeks to dismantle the current structure of government. The businesses supplying federal agencies thus face great uncertainty about future contracts. Laid-off workers will be forced to cut their spending, which will have knock-on effect on business, who will cut employment and investment as the multiplier and accelerator work through.

There are also worries that the economic chaos caused by President Trump’s frequent policy changes will cause inflation to rise. Higher inflation will prompt the Federal Reserve to raise interest rates. This, in turn, will increase the cost of borrowing for investment.

Tariff uncertainty

Perhaps the biggest uncertainty for business concerns the imposition of tariffs. Many US businesses rely on imports of raw materials, components, equipment, etc. Imposing tariffs on imports raises business costs. But this will vary from firm to firm, depending on the proportion of their inputs that are imported. And even when the inputs are from other US companies, those companies may rely on imports and thus be forced to raise prices to their customers. And if, in retaliation, other countries impose tariffs on US goods, this will affect US exporters and discourage them from investing.

For many multinational companies, whether based in the USA or elsewhere, supply chains involve many countries. New tariffs will force them to rethink which suppliers to use and where to locate production. The resulting uncertainty can cause them to delay or cancel investments.

Uncertainty has also been caused by the frequent changes in the planned level of tariffs. With the Trump administration using tariffs as a threat to get trading partners to change policy, the threatened tariff rates have varied depending on how trading partners have responded. There has also been uncertainty on just how the tariff policy will be implemented, making it more difficult for businesses to estimate the effect on them.

Then there are serious issues for the longer term. Other countries will be less willing to sign trade deals with the USA if they will not be honoured. Countries may increasingly look to diverting trade from the USA to other countries.
