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.

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.

In an interview with Joe Rogan for his podcast, The Joe Rogan Experience, just before the US election, Donald Trump stated that, “To me, the most beautiful word – and I’ve said this for the last couple of weeks – in the dictionary today and any is the word ‘tariff’. It’s more beautiful than love; it’s more beautiful than anything. It’s the most beautiful word. This country can become rich with the use, the proper use of tariffs.”
President-elect Trump has stated that he will impose tariffs on imports of 10% or 20%, with 60% and 100% tariffs on imports from China and Mexico, respectively. This protection for US industries, combined with lighter regulation, will, he claims, provide a stimulus to the economy and help create jobs. The revenues will also help to reduce America’s budget deficit.
But it is not that straightforward.
Problems with tariffs for the USA
Imposing tariffs is likely to reduce international trade. But international trade brings net benefits, which are distributed between the participants according to the terms of trade. This is the law of comparative advantage.
In the simple two-country case, the law states that, provided the opportunity costs of producing various goods differ between the two countries, both of them can gain from mutual trade if they specialise in producing (and exporting) those goods that have relatively low opportunity costs compared with the other country. The total production and consumption of the two countries will be higher.
So if the USA has a comparative advantage in various manufactured products and a trading partner has a comparative advantage in tropical food products, such as coffee or bananas, both can gain by specialisation and trade.
If tariffs are imposed and trade is thereby reduced between the USA and its trading partners, there will be a net loss, as production will switch from lower-cost production to higher-cost production. The higher costs of less efficient production in the USA will lead to higher prices for those goods than if they were imported.
At the same time, goods that are still imported will be more expensive as the price will include the tariff. Some of this may be borne by the importer, meaning that only part of the tariff is passed on to the consumer. The incidence of the tariff between consumer and importer will depend on price elasticities of demand and supply. Nevertheless, imports will still be more expensive, allowing the domestically-produced substitutes to rise in price too, albeit probably by not so much. According to work by Kimberly Clausing and Mary E Lovely for the Peterson Institute (see link in Articles below), Trump’s proposals to raise tariffs would cost the typical American household over $2600 a year.
The net effect will be a rise in inflation – at least temporarily. Yet one of Donald Trump’s pledges is to reduce inflation. Higher inflation will, in turn, encourage the Fed to raise interest rates, which will dampen investment and economic growth.
Donald Trump tends to behave transactionally rather than ideologically. He is probably hoping that a rapid introduction of tariffs will then give the USA a strong bargaining position with foreign countries to trade more fairly. He is also hoping that protecting US industries by the use of tariffs, especially when coupled with deregulation, will encourage greater investment and thereby faster growth.
Much will depend on how other countries respond. If they respond by raising tariffs on US exports, any gain to industries from protection from imports will be offset by a loss to exporters.
A trade war, with higher tariffs, will lead to a net loss in global GDP. It is a negative sum game. In such a ‘game’, it is possible for one ‘player’ (country) to gain, but the loss to the other players (countries) will be greater than that gain.
Donald Trump is hoping that by ‘winning’ such a game, the USA could still come out better off. But the gain from higher investment, output and employment in the protected industries would have to outweigh the losses to exporting industries and from higher import prices.
The first Trump administration (2017–21), as part of its ‘America First’ programme, imposed large-scale tariffs on Chinese imports and on steel and aluminium from across the world. There was wide-scale retaliation by other countries with tariffs imposed on a range of US exports. There was a net loss to world income, including US GDP.
Problems with US tariffs for the rest of the world
The imposition of tariffs by the USA will have considerable effects on other countries. The higher the tariffs and the more that countries rely on exports to the USA, the bigger will the effect be. China and Mexico are likely to be the biggest losers as they face the highest tariffs and the USA is a major customer. In 2023, US imports from China were worth $427bn, while US exports to China were worth just $148bn – only 34.6% of the value of imports. The percentage is estimated to be even lower for 2024 at around 32%. In 2023, China’s exports to the USA accounted for 12.6% of its total exports; Mexico’s exports to the USA accounted for 82.7% of its total exports.
It is possible that higher tariffs could be extended beyond China to other Asian countries, such as Vietnam, South Korea, Taiwan, India and Indonesia. These countries typically run trade surpluses with the USA. Also, many of the products from these countries include Chinese components.
As far as the UK is concerned, the proposed tariffs would cause significant falls in trade. According to research by Nicolò Tamberi at the University of Sussex (see link below in Articles):
The UK’s exports to the world could fall by £22 billion (–2.6%) and imports by £1.4 (–0.16%), with significant variations across sectors. Some sectors, like fishing and petroleum, are particularly hard-hit due to their high sensitivity to tariff changes, while others, such as textiles, benefit from trade diversion as the US shifts demand away from China.
Other badly affected sectors would include mining, pharmaceuticals, finance and insurance, and business services. The overall effect, according to the research, would be to reduce UK output by just under 1%.
Countries are likely to respond to US tariffs by imposing their own tariffs on US imports. World Trade Organization rules permit the use of retaliatory tariffs equivalent to those imposed by the USA. The more aggressive the resulting trade war, the bigger would be the fall in world trade and GDP.
The EU is planning to negotiate with Trump to avoid a trade war, but officials are preparing the details of retaliatory measures should the future Trump administration impose the threatened tariffs. The EU response is likely to be strong.

A common practice of international investors is to take part in the so-called ‘carry trade’. This involves taking advantage of nominal interest rate differences between countries. For example, assume that interest rates are low in Japan and high in the USA. It is thus profitable to borrow yen in Japan at the low interest rate, exchange it into US dollars and deposit the money at the higher interest rate available in the USA. If there is no change in the exchange rate between the dollar and the yen, the investor makes a profit equal to the difference in the interest rates.
Rather than depositing the money in a US bank account, an alternative is to purchase US bonds or other assets in the USA, where the return is again higher than that in Japan.
If, however, interest-rate differentials narrow, there is the possibility of the carry trade ‘unwinding’. Not only may the carry trade prove unprofitable (or less so), but investors may withdraw their deposits and pay back the loans. This, as we shall, can have adverse consequences on exchange rates.
The problem of an unwinding of the carry trade is not new. It worsened the underlying problems of the financial crisis in 2008. The question today is whether history is about to repeat itself with a new round of unwinding of the carry trade threatening economic growth and recovery around the world.
We start by looking at what happened in 2008.
The carry trade and the 2008 financial crisis
Prior to the financial crisis of 2008, current account deficit countries, such as the UK, USA and Australia, typically had relatively high interest rates, while current account surplus countries such as Japan and Switzerland had relatively low ones. Figure 1 shows central bank interest rates from 2005 to the current day (click here for a PowerPoint).
The carry trade saw investors borrowing money in Japan and Switzerland, exchanging it on the foreign exchange market, with the currency then deposited in the UK, USA and Australia. Hundreds of billions worth of dollars were involved in this carry trade.
If, however, the higher interest rates in the UK and other deficit countries were simply to compensate investors for the risk of currency depreciation, then there would be no excessive inflow of finance. The benefit of the higher interest rate would be offset by a depreciating currency. But the carry trade had the effect of making deficit currencies appreciate, thereby further boosting the carry trade by speculation of further exchange rate rises.
Thus the currencies of deficit countries appreciated, making their goods less competitive and worsening their current account deficit. Between 1996 and 2006, the average current account deficits as a percentage of GDP for Australia, the USA and the UK were close to 4½, 4 and 2, respectively. Between January 1996 and December 2006, the broad-based real exchange rate index of the Australian dollar appreciated by 17%, of the US dollar by 4% and of sterling by some 23%.
Currencies of surplus countries depreciated, making their goods more competitive and further boosting their current account surpluses. For example, between 2004 and 2006 the average current account surpluses as a percentage of GDP for Japan and Switzerland were 3½ and 13, respectively. Their short-term interest rates averaged a mere 0.1% and 1.0% respectively (compared with 3.4%, 4.7% and 5.7% for the USA, the UK and Australia). Yet between January 2004 and December 2006, the real exchange rate index of the yen depreciated by 21%, while that of the Swiss franc depreciated by 6%.
With the credit crunch of 2007/8, the carry trade unwound. Much of the money deposited in the USA had been in highly risky assets, such as sub-prime mortgages. Investors scrambled to sell their assets in the USA, UK and the EU. Loans from Japan and Switzerland were repaid and these countries, seen as ‘safe havens’, attracted deposits. The currencies of deficit countries, such as the UK and USA, began to depreciate and those of surplus countries, such as Japan and Switzerland, began to appreciate. Between September 2007 and September 2008, the real exchange rate indices of the US dollar and sterling depreciated by 2% and 13% respectively; the yen and the Swiss franc appreciated by 3% and 2¾%.
This represented a ‘double whammy’ for Japanese exporters. Not only did its currency appreciate, making its exports more expensive in dollars, euros, pounds, etc., but the global recession saw consumers around the world buying less. As a result, the Japanese economy suffered the worst recession of the G7 economies.
The carry trade in recent months
Since 2016, there has been a re-emergence of the carry trade as the Fed began raising interest rates while the Bank of Japan kept rates at the ultra low level of –0.1% (see Figure 1). The process slowed down when the USA lowered interest rates in 2020 in response to the pandemic and fears of recession. But when the USA, the EU and the UK began raising rates at the beginning of 2022 in response to global inflationary pressures, while Japan kept its main rate at –0.1%, so the carry trade resumed in earnest. Cross-border loans originating in Japan (not all of it from the carry trade) had risen to ¥157tn ($1tn) by March 2024 – a rise of 21% from 2021.
The process boosted US stock markets and contributed to the dollar appreciating against the yen (see Figure 2: click here for a PowerPoint).
Although this depreciation of the yen helped Japanese exports, it also led to rising prices. Japanese inflation rose steadily throughout 2022. In the 12 months to January 2022 the inflation rate was 0.5% (having been negative from October 2020 to August 2021). By January 2023, the annual rate had risen to 4.3% – a rate not seen since 1981. The Bank of Japan was cautious about raising interest rates to suppress this inflation, however, for fear of damaging growth and causing the exchange rate to appreciate and thereby damaging exports. Indeed, quarterly economic growth fell from 1.3% in 2023 Q1 to –1.0% in 2023 Q3.
But then, with growth rebounding and the yen depreciating further, in March 2024 the Bank of Japan decided to raise its key rate from –0.1% to 0.1%. This initially had the effect of stabilising the exchange rate. But then with the yen depreciating further and inflation rising from 2.5% to 2.8% in May and staying at this level in June, the Bank of Japan increased the key rate again at the end of July – this time to 0.25% – and there were expectations that there would be another rise before the end of the year.
At the same time, there were expectations that the Fed would soon lower its main rate (the Federal Funds Rate) from its level of 5.33%. The ECB and the Bank of England had already begun lowering their main rates in response to lower inflation. The carry trade rapidly unwound. Investors sold US, EU and UK assets and began repaying yen loans.
The result was a rapid appreciation of the yen as Figure 3 shows (click here for a PowerPoint). Between 31 July (the date the Bank of Japan raised interest rates the second time) and 5 August, the dollar depreciated against the yen from ¥150.4 to ¥142.7. In other words, the value of 100 yen appreciated from $0.66 to $0.70 – an appreciation of the yen of 6.1%.
Fears about the unwinding of the carry trade led to falls in stock markets around the world. Not only were investors selling shares to pay back the loans, but fears of the continuing process put further downward pressure on shares. From 31 July to 5 August, the US S&P 500 fell by 6.1% and the tech-heavy Nasdaq by 8.0%.
As far as the Tokyo stock market was concerned, the appreciation of the yen sparked fears that the large Japanese export sector would be damaged. Investors rushed to sell shares. Between 31 July and 5 August, the Nikkei 225 (the main Japanese stock market index) fell by 19.5% – its biggest short-term fall ever (see Figure 4: click here for a PowerPoint).
Although the yen has since depreciated slightly (a rise in the yen/dollar rate) and stock markets have recovered somewhat, expectations of many investors are that the unwinding of the yen carry trade has some way to go. This could result in a further appreciation of the yen from current levels of around ¥100 = $0.67 to around $0.86 in a couple of years’ time.
There are also fears about the carry trade in the Chinese currency, the yuan. Some $500 billion of foreign currency holdings have been acquired with yuan since 2022. As with the Japanese carry trade, this has been encouraged by low Chinese interest rates and a depreciating yuan. Not only are Chinese companies investing abroad, but foreign companies operating in China have been using their yuan earnings from their Chinese operations to invest abroad rather than in China. The Chinese carry trade, however, has been restricted by the limited convertibility of the yuan. If the Chinese carry trade begins to unwind when the Chinese economy begins to recover and interest rates begin to rise, the effect will probably be more limited than with the yen.

Gold has always held an allure and with the price of gold on international markets trending upwards since October 2022 (see Figure 1: click here for a PowerPoint), people seem to be attracted to it once again. The price reached successively higher peaks throughout 2023 before surging to above $2300 per oz in 2024 and peaking at $2425.31 per oz on 20 May 2024.
While gold tends to become attractive during wartime, economic uncertainty and bouts of inflation, all of which have characterised the last few years, the sustained price rise has perplexed market analysts and economists. The rally had been expected to peter out over the past 20 months. But, as the price of gold rose to sustained higher levels, with no significant reversals, some analysts have speculated that it is not the typical short-term factors which are driving the increased demand for and price of gold but more fundamental changes in the global economic system.
This blog will first discuss the typical short-term factors which influence gold prices before discussing the potential longer-term forces that may be at work.
Short-term factors
So, what are the typical short-term economic forces which drive the demand for gold?
The most significant are the real rates of interest on financial assets. These rates represent the opportunity cost of holding an asset such as gold which offers no income stream. When the real return from financial assets like debt and equity instruments is low, the demand for and price of gold tends to be high. In contrast, when the real return from such assets is high, the price of gold tends to be lower. An explanation for this is that real rates of return are strongly related to inflation rates and investors perceive gold as a hedge against inflation since its price is positively correlated with a general rise in prices. Higher unexpected inflation reduces the real rate of return of securities like debt and equity whose value is derived from cash flows anticipated in the future. In such circumstances, gold become an attractive alternative investment. As inflationary expectations decline, real returns from financial assets should rise, and the demand for gold should fall.
The relationship between real returns, proxied by the yield on US 10-year TIPS (Treasury inflation-protected securities), and gold prices can be used to examine this explanation. Real returns rose steadily in the aftermath of the COVID-19 pandemic. Yet the price of gold, which rose during the early stages of the pandemic in 2020, has not fallen. Instead, it has remained at elevated levels for much of that time (see Figure 2: click here for a PowerPoint).
There have been short periods when changes in real returns seemed to have a high correlation with changes in gold prices. In late 2022, for example, falling real rates coincided with rising gold prices. The same pattern was repeated between October and December 2023. However, when real returns rose again in the New Year of 2024, in response to stubbornly higher expected inflation and the expectation of ‘higher-for-longer’ interest rates, particularly in the USA, gold prices continued to rise. Indeed, across the 5-year period the correlation coefficient between the two series is actually positive at 0.268, showing little evidence supporting this explanation for the pattern for the gold price.
Real returns in the USA, however, may not be the correct ones to consider when seeking explanations for the pattern of gold’s price. Much of the recent demand is from China. Analysts suggest that Chinese investors are looking for a safe asset to hold as their economy stagnates and real returns from alternatives, like domestic property and equity, have decreased. Further, there are some concerns that the Chinese currency, the renminbi, may be undervalued in response to the sluggish growth. Holding gold is a good hedge against inflation (currency depreciation produces inflationary pressure). Consequently, the Chinese market may be exerting pricing power in relation to real returns in a way not seen before (see the Dempsey and Leng FT article linked below).
However, some analysts suggest that the rise in price is disproportionate to these short-term factors and point to potential long-term structural changes in the global financial order which may produce significant changes in the market for gold.
Long-term factors
Since 2018, there have been bouts of gold purchasing by central banks around the world. In contrast to the 1990s and 2000s, central banks have been net purchasers since 2010. The purchasing fell back during the coronavirus pandemic but has surged again, with over 1000 metric tonnes purchased in both 2022 and 2023 (see Figure 3: click here for a PowerPoint).
Analysts have pointed to similarities between the recent pattern and central bank purchases of gold during the late 1960s and early 1970s (see The Conversation article linked below). Then, central banks sought to diversify themselves from dollar-denominated assets due to concerns about higher inflation in the USA and its impact on the value of the US dollar. Under the Bretton Woods fixed exchange rate system, central banks could redeem dollars for gold from the US Federal Reserve at a fixed rate. The pressure on the USA to redeem the gold led to the collapse of the Bretton Woods fixed exchange rate system.
While the current period of central bank purchases does not appear to be related to expected inflation, some commentators suggest it could signal a regime change in the global financial system as significant as the collapse of Bretton Woods. The rise of Chinese political power and the resurgence of US isolationist tendencies portend an increasingly multipolar geopolitical scene. Such concerns may cause central bankers to diversify away from dollar denominated assets to avoid being caught out by geopolitical tensions. Gold may be perceived as an asset through which investors can hedge that risk better.
Indeed, the rise in demand among Chinese investors may indicate a reluctance to hold US assets due to their risk of seizure during heightened geopolitical tensions between China and the USA. Chinese holdings of US financial assets as a percentage of GDP are back to the level they were when the country joined the World Trade Organisation (WTO) in 2001 (see the Rana Foroohar FT article linked below). Allied to this is an increasing tendency to repatriate gold bullion from centres such as London and New York.
Added to these worries about geopolitical risk are concerns about traditional safe-haven assets – government debt securities. US government budget deficits and debt levels continue to rise. Similar patterns are observed across many developed market economies (DMEs). Analysts are concerned such debts are reaching unsustainable levels (economist.com). The view is that at some point, perhaps soon, a tipping point will be reached where investors recognise this. They will demand higher rates of return on these government debt securities, pushing yields up and prices down (bond yields and prices have a negative relationship).
In expectation of this, investors may be wary of holding such government debt securities and move to hold gold as an alternative safe-haven asset to avoid potential capital losses. However, there has been no sign of this behaviour in bond prices and yields yet.
Finally, there are economists who argue that the increased demand for gold is caused by a different regime-change in the global economy. This is not one driven by geopolitics, but by changing inflationary expectations – from a low-inflation, low-interest-rate environment to a higher-inflation, higher-interest-rate environment.
Some of the anticipation relating to inflation is derived from the persistent fiscal stimulus, evidenced by the higher government debt levels described above, coupled with the long period of monetary stimulus (quantitative easing) in developed market economies during the 2010s.
Further, some economists highlight the substantial capital investment needed for the green transition and reindustrialisation. While the financing for this capital investment may absorb some of the excess money flowing around financial markets, the scale involved will create a great demand for resources, fuelling inflation and raising the cost of capital as borrowers compete for resources.
Finally, the demographic forces from an aging population will also cause inflationary pressures. Rising dependency ratios across many developed market economics will create shortages, particularly of labour. This persistent scarcity of labour will continually drive up wages and prices, fuelling inflation and the demand for gold.
Conclusion
The recent surge in the price of gold has led to great interest by investors, financial market analysts and economists. At first, there was a perception that the price increase was similar to recent history and driven by short-term decreases in the real rate of return from financial assets, which reduced the opportunity cost of holding gold.
However, as the upward trend in the price of gold has persisted and does not seem to be explained by changes in real interest rates, economists have considered other reasons that might signal longer-term significant changes in the global financial system. These relate to changing geopolitical risk derived from an increasingly multipolar environment, concerns about the sustainability of government debt levels and expectations of persistently higher inflation in the world economy.
Only time will tell whether these explanations prove correct. If inflationary pressures subside, particularly in the USA, and if real returns from financial assets rebound, a decrease in the demand for and price of gold will suggest that the previous rise was driven by short-term forces.
If prices don’t fall back, it will only fuel the debate that it is a sign of significant changes in the global financial order.
