The yen has been depreciating against the dollar and other currencies for several months. It fell from 100 yen = $0.97 in January 2021 to $0.61 by the end of July 2026 – a fall of 37%. This marked a 40-year low. But then, at the end of July it rallied and by 3 August the rate was 100 yen = $0.64 – a rise of nearly 5%. But why did this happen and what will be the implications for Japan and the wider world economy?
Why has the yen fallen so much since 2021?
There have been two main drivers.
The first is fiscal policy. For many years, Japan has been pursuing expansionary fiscal policy in an attempt to stimulate the sluggish economy. This has led to large budget deficits and public-sector debt. Since 2020, general government gross debt has been around 255% of GDP, the largest of any high-income economy.
Recently, the Japanese government has adopted aggressive supplementary budgets to fund, among other things, fuel subsidies and public-private investment initiatives. This has involved the issuance of more government bonds to fund the necessary borrowing.
Fiscal pressures have also increased becase of demography. A rapidly aging population and declining birth rates have required substantial public spending on healthcare, social security and pensions. Meanwhile, the tax-paying working-age population has declined as a proportion of total population.
On the plus side, unlike most highly indebted nations, over 90% of Japan’s debt is held domestically by Japanese residents, Japanese institutional investors, banks and the Bank of Japan (BoJ). This lowers the risk of default and hence the risk premium on Japanese bonds.
The second driver is monetary policy. Interest rates have been kept low over many years, including periods of negative rates, as the BoJ has attempted to stimulate the economy. Low interest rates have sometimes been backed up with quantitative easing to increase money supply.
Since March 2024, however, there have been four interest rate increases. The latest was in June 2026 when the BoJ raised the short-term policy rate from 0.75% to 1.0% – the highest level since 1995. Despite this, interest rates have remained below those in other countries, and this contributed to the continuing fall of the yen.
A falling yen has helped to increase Japanese exports by making them more competitive, but more expensive imports have contributed to rising Japanese inflation.
Low interest rates have also stimulated the yen-dollar carry trade. This is where investors borrow money in yen at low interest rates, convert it into US dollars and invest it in higher-yielding US assets, typically US government bonds (‘Treasury bonds’). This borrowing in yen to buy dollars further contributed to the depreciation of the yen against the dollar.
Co-ordinated intervention
In an attempt to raise the value of the yen, the Bank of Japan and the US Federal Reserve acted together – their first joint currency rescue operation since 2011. The BoJ spent tens of billions of dollars to buy yen; the US Treasury bought yen by selling euros. Prior to the intervention, global hedge funds held near-record short positions against the yen, meaning that they sold yen at a current price, agreeing to buy them back at a particular later date, hoping that the yen would fall in the meantime and that they would therefore make a profit. The sudden joint intervention forced these traders to buy back the yen to cut their losses before the rate rose further. This accelerated the yen’s appreciation.
But why did the USA join Japan in intervening? Japan is the largest foreign holder of US Treasuries ($1.1 trillion). The USA intervened to discourage Japanese investors from selling US Treasuries in order to raise cash, thereby pushing up US borrowing costs.
The rise in the yen was also encouraged by speculators who are expecting further interest rate rises from the BoJ to counter inflation and support public finances, driving domestic bond yields higher. This will lead to a narrowing of interest rates between Japan and other countries.
Effects on the Japanese economy
If the yen continues to appreciate, this will help to reduce inflation by making imports cheaper and will help to ease cost-of-living pressures on Japanese consumers. Japan is heavily reliant on imported energy and raw materials.
However, the decline in the yen over recent years has provided a large boost to Japanese exports. A sharp reversal in this could severely affect exporters’ profits and have a serious negative impact on economic growth.
If the appreciation continues, it would lead to an unwinding of the carry trade. To prevent mounting currency losses, highly leveraged institutional investors would be forced to sell assets, such as US and other countries’ shares and bonds to buy back yen and pay off their debts. This potentially massive unwinding would be likely to create global market volatility and drive up interest rates.

At the fourth anniversary of Russia’s invasion of Ukraine, we look at the effect of the war on the Russian economy. Two years ago, in the blog The Russian economy after two years of war, we argued that the Russian economy had seemingly weathered the war successfully.
Unlike Ukraine, very little of its infrastructure had been destroyed; it had started the war with a current account balance of payments surplus, a budget surplus and a low general government debt-to-GDP ratio; it had achieved a lot of success in diverting its exports, including oil, away from countries imposing sanctions to countries such as China and India; it was the same with imports, with China especially becoming a major suppliers of machinery, components and vehicles; it has a strong central bank, which engenders a high level of confidence in managing inflation; the military expenditure provided a Keynesian boost to the economy, with production and employment rising.
The situation today
But two years further on, the Russian economy is looking a lot weaker and on the verge of recession. GDP growth fell to 0.6 per cent in 2025 and is forecast to be no more than 1 per cent for the next two years. (Click here for a PowerPoint of the chart.) And despite growth still being positive (just), this is largely because of the growth in military expenditure. Retail and wholesale trade fell by 1.1% in 2025, reflecting supply chain problems and high inflation dampening consumer demand.
With labour being diverted into the armaments and allied industries or into the armed forces, this has led to labour shortages. This has been compounded by the emigration of up to 1 million people by 2025 – often young, educated and skilled professionals.
Official CPI inflation averaged 8.7 per cent in 2025, although the prices of food and other consumer essentials rose by more, especially in recent months. At the beginning of 2026, supermarket prices rose by 2.3% in just one month, made worse by a rise in VAT from 20% to 22%. The central bank has responded to the high inflation with high interest rates, which averaged 19.2% in 2025, giving a real rate of 10.5%. With such a high real rate, the response of households has been to save. This has masked the constraints on production, or imports, of consumer goods. Savings have also been boosted by large payments to soldiers and bereaved families, with the money saved by the recipients being used in part to fund future such payments. So far there has been trust in the banking system, but if that trust waned and people starting making large withdrawals of savings, it could be seriously destabilising.
Whilst the high real interest rates have helped to mask shortages of consumer goods, they have had a seriously dampening effect on investment by domestic companies. Gross capital formation fell by 3% in 2025, not helped by an increase in the corporation tax from 20% to 25%. At the same time, foreign direct investment remains subdued due to high perceived risks. The lack of investment, plus the labour shortages, will have profound effects on the supply side of the economy, with potential output in the non-military sector likely to decline over the medium term.
The balance of payments and government finances are turning less favourable. The balance of trade surplus has declined from US$173bn in 2021 to US$67bn in 2025. This could decline further, or even become a deficit, if oil prices continue to be weak, if Western sanctions are tightened (such as stopping the flow of Russian oil exports in the ‘shadow’ fleet of tankers) or if major importing countries stop buying Russian oil. Indian refiners have announced that they are not taking Russian crude in March/April as India seeks to finalise a trade deal with the USA.
The budget balance has moved from a small surplus of 0.8% of GDP in 2021 to a deficit of 2.9% in 2025. Although the government debt-to-GDP ratio remains low by international standards at 23.1% of GDP in 2025, this was up from 16.5% in 2021 and is set to rise further as budget deficits deepen. Nevertheless, as long as the saving rate remains high, the debt can be serviced by domestic bond purchase.
Russia’s economy is definitely weakening and labour shortages and low investment will create major problems for the future. But whether this deterioration will be enough to change Russia’s stance on the war in Ukraine remains to be seen.

Three recent reports (see links below) have suggested that US consumers and businesses pay most of the tariffs imposed by the second Trump administration. The percentage varies from around 86% to 96%. US customs revenue surged by approximately $200 billion in 2025, but this was a tax paid almost entirely by US consumers and businesses. Foreign suppliers largely maintained their (pre-tariff) prices. They took a hit in terms of reduced volumes rather than reduced pre-tariff prices.
The incidence of a tariff between consumers, domestic importers and overseas producers will depend on price elasticities of demand and supply. The following diagram shows a product where the importing country is large enough to have a degree of market power, which will normally be the case with the USA. The greater its buying power, the flatter will be its demand curve, showing that the foreign supplier will have little influence on the price. With no tariff, the equilibrium price paid by importers will be at point a, where demand equals supply. Q1 would be imported at a price of P1.
Imposition of a tariff will shift the supply curve upwards by the amount of the tariff. The new equilibrium price paid by importers will be at point b, where the new supply curve crosses the demand curve. Importers thus now pay a post-tariff price of P2: an effective rise in price of P2 minus P1. Foreign exporters receive P3, which is what they are paid by importers after the tariff has been paid.
The consumer price will be above P2 as that includes a mark-up by US businesses on top of the price they pay to import the product. Importers may bear some of the increase in price and not pass the full amount onto consumers, depending on competition and their ability to absorb cost increases.
President Trump argued that there would be very little rise in price from the tariffs and that overseas suppliers would bear the brunt of the tariffs. Indeed, recently he has argued that this must be the case as US inflation has been falling. In response, critics maintain that the rate of inflation would have fallen more without the tariffs and that current prices would be lower than they are. Also, if US importing firms or retailers bear some of the increased cost, even though this helps to dampen the price rise, their lower profits could damage investment and employment.

The Reports
The first report is from the New York Fed (one of the regional branches of the Federal Reserve Bank). It examines the effect of tariffs imposed in 2025, over three periods: (i) January to August, (ii) September to October, and (iii) November. In the first period, 94% of the tariffs were paid by US importers and 6% by foreign exports; in the second period, the figures were 92% and 8% and in the third period, 86% and 14%.
The second report is The Budget and Economic Outlook: 2026 to 2036 from the Congressional Budget Office. Box 2-1 notes that, as of November 2025, ‘the effective tariff rate was about 13 percentage points higher than the roughly 2 percent rate on imports in 2024’. Its analysis suggests that 95% of the tariffs will be borne by importers. Of these higher import prices, 30% will be borne by US businesses, largely through reduced profit margins, and 70% by consumers through higher prices. This will also allow many businesses which produce goods that compete with foreign imports to ‘increase their prices because of the decline in competition from abroad and the increased demand for tariff-free domestic goods’.
The third report is from the Kiel Insitut. In its Policy Brief, Americaʼs Own Goal: Who Pays the Tariffs?, it finds that US importers and consumers bear 96% of the cost of the 2025 tariffs, with foreign exporters absorbing only about 4%. It bases it findings on shipment-level data covering over 25 million transactions valued at nearly $4 trillion. This also shows that exports to the USA declined as foreign exporters preferred to reduce volumes rather than absorbing the tariffs.
The tariffs raised some $200 billion in 2025, around 3.8% of Federal tax receipts. But, as we have seen, this was paid largely by US consumers and business. It goes some way to offsetting the annual cut in tax revenues of around $450 to $520 billion per year from the tax cuts, largely to the better off, in Trump’s ‘One Big Beautiful Bill’.

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.

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.
