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.

We have examined inflation in several blogs in recent months. With inflation at levels not seen for 40 years, this is hardly surprising. One question we’ve examined is whether the policy response has been correct. For example, in July, we asked whether the Bank of England had raised interest rates too much, too late. In judging policy, one useful distinction is between demand-pull inflation and cost-push inflation. Do they require the same policy response? Is raising interest rates to get inflation down to the target rate equally applicable to inflation caused by excessive demand and inflation caused by rising costs, where those rising costs are not caused by rising demand?
In terms of aggregate demand and supply, demand-pull inflation is shown by continuing rightward shifts in aggregate demand (AD); cost-push inflation is shown by continuing leftward/upward shifts in short-run aggregate supply (SRAS). This is illustrated in the following diagram, which shows a single shift in aggregate demand or short-run aggregate supply. For inflation to continue, rather than being a single rise in prices, the curves must continue to shift.
As you can see, the effects on real GDP (Y) are quite different. A rise in aggregate demand will tend to increase GDP (as long as capacity constraints allow). A rise in costs, and hence an upward shift in short-run aggregate supply, will lead to a fall in GDP as firms cut output in the face of rising costs and as consumers consume less as the cost of living rises.
The inflation experienced by the UK and other countries in recent months has been largely of the cost-push variety. Causes include: supply-chain bottlenecks as economies opened up after COVID-19; the war in Ukraine and its effects on oil and gas supplies and various grains; and avian flu and poor harvests from droughts and floods associated with global warming resulting in a fall in food supplies. These all led to a rise in prices. In the UK’s case, this was compounded by Brexit, which added to firms’ administrative costs and, according to the Bank of England, was estimated to cause a long-term fall in productivity of around 3 to 4 per cent.
The rise in costs had the effect of shifting short-run aggregate supply upwards to the left. As well as leading to a rise in prices and a cost-of-living squeeze, the rising costs dampened expenditure.
This was compounded by a tightening of fiscal policy as governments attempted to tackle public-sector deficits and debt, which had soared with the support measures during the pandemic. It was also compounded by rising interest rates as central banks attempted to bring inflation back to target.
Monetary policy response
Central banks are generally charged with keeping inflation in the medium term at a target rate set by the government or the central bank itself. For most developed countries, this is 2% (see table in the blog, Should central bank targets be changed?). So is raising interest rates the correct policy response to cost-push inflation?
One argument is that monetary policy is inappropriate in the face of supply shocks. The supply shocks themselves have the effect of dampening demand. Raising interest rates will compound this effect, resulting in lower growth or even a recession. If the supply shocks are temporary, such as supply-chain disruptions caused by lockdowns during the pandemic, then it might be better to ride out the problem and not raise interest rates or raise them by only a small amount. Already cost pressures are easing in some areas as supplies have risen.
If, however, the fall in aggregate supply is more persistent, such as from climate-related declines in harvests or the Ukraine war dragging on, or new disruptions to supply associated with the Israel–Gaza war, or, in the UK’s case, with Brexit, then real aggregate demand may need to be reduced in order to match the lower aggregate supply. Or, at the very least, the growth in aggregate demand may need to be slowed to match the slower growth in aggregate supply.
Huw Pill, the Chief Economist at the Bank of England, in a podcast from the Columbia Law School (see links below), argued that people should recognise that the rise in costs has made them poorer. If they respond to the rising costs by seeking higher wages, or in the case of businesses, by putting up prices, this will simply stoke inflation. In these circumstances, raising interest rates to cool aggregate demand may reduce people’s ability to gain higher wages or put up prices.
Another argument for raising interest rates in the face of cost-push inflation is when those cost increases are felt more than in other countries. The USA has suffered less from cost pressures than the UK. On the other hand, its growth rate is higher, suggesting that its inflation, albeit lower than in the UK, is more of the demand-pull variety. Despite its inflation rate being lower than in the UK, the problem of excess demand has led the Fed to adopt an aggressive interest rate policy. Its target rate is 5.25% to 5.50%, while the Bank of England’s is 5.25%. In order to prevent short-term capital outflows and a resulting depreciation in the pound, further stoking inflation, the Bank of England has been under pressure to mirror interest rate rises in the USA, the eurozone and elsewhere.

Following the recession of 2008/9, the UK has engaged in four rounds of quantitative easing (QE) – the process whereby the central bank increases the money supply by purchasing government bonds, and possibly other assets, on the open market from various institutions. The final round was announced in July 2012, bringing the total assets purchased to £375bn. As yet, however, there are no plans for quantitative tightening – the process of the Bank of England selling some of these assets, thereby reducing money supply.
The aim of QE has been to stimulate aggregate demand. Critics claim, however, that the effect on spending has been limited, since the money has not gone directly to consumers but rather to the institutions selling the assets, who have used much of the money to buy shares, bonds and other assets. Nevertheless, with banks having to strengthen their capital base following the financial crisis, QE has helped then to achieve this without having to make even bigger reductions in lending.
The Bank of England now reckons that the recovery is sufficiently established and there is, therefore, no need for further QE.
This is also the judgement of the Federal Reserve about the US economy, which experienced annual growth of 3.5% in the third quarter of 2014. The IMF predicts that US growth will be around 3% for the next three years.
The Fed has had three rounds of QE since the financial crisis, but in October 2014 called an end to the process. Since the start of this year, it has been gradually reducing the amount it injects each month from $85bn to $15bn. The total bond purchases over the past five years have been some $3.6tn, bringing the Fed’s balance sheet to nearly $4.5tn.
But as QE comes to an end in the USA, Japan is expanding its programme. On 31 October, the Bank of Japan announced that it would increase its asset purchases from ¥60-70tn per year to ¥80tn (£440bn). The Japanese government and central bank are determined to boost economic growth in Japan and escape the two decades of deflation and stagnation. The Tokyo stock market rose by some 8% in the week following the announcement and the yen fell by more than 5% against the dollar.
And the European Central Bank, which has not used full QE up to now, looks as if it is moving in that direction. 
In October, it began a programme of buying asset-backed securities (ABSs) and covered bonds (CBs). These are both private-sector securities: ABSs are claims against non-financial companies in the eurozone and CBs are issued by eurozone banks and other financial institutions.
It now looks as if the ECB might take the final step of purchasing government bonds. This is probably what is implied by ECB President Mario Draghi’s statement after the 6 November meeting of the ECB that the ground was being prepared for “further measures to be implemented, if needed”.
But has QE been as successful as its proponents would claim? Is it the solution now to a languishing eurozone economy? The following articles look at these questions.

With many countries struggling to recover from the depression of the past few years, central banks are considering more and more doveish moves to kick-start lending. But with short-term interest rates in the USA, the UK and Japan close to zero, the scope for further cuts are limited. So what can central banks do?
The first thing that can be done is to adopt a higher inflation target or to accept inflation above target – at least for the time being. This could be accompanied by explicitly targeting GDP growth (real or nominal) or unemployment (see the blog from last December, Rethinking central bank targets).
The second option is to increase quantitative easing. Although in a minority at the last MPC meeting, Mervyn King, the current Bank of England Governor, argued for a further £25 billion of asset purchases (bringing the total to £400bn) (see MPC minutes paragraph 39). It is highly likely that the MPC will agree to further QE at its next meeting in March. In Japan, the new governor of the Bank of Japan is expected to include asset purchases as part of the policy of monetary easing.
The third option is for the central bank to provide finance at below-market rates of interest directly to the banking sector specifically for lending: e.g. to small businesses or for house purchase. The Bank of England’s Funding for Lending Scheme is an example and the Bank is considering extending it to other financial institutions.
One other approach, mooted by the Bank of England’s Deputy Governor before the House of Commons Treasury Select Committee, is for negative interest rates paid on Banks’ reserves in the Bank of England. This would, in effect, be a fee levied on banks for keeping money on deposit. The idea would be to encourage banks to lend the money and not to keep excessive liquidity. As you can see from the chart, three rounds of quantitative easing have led to a huge increase in bank’s reserves at the Bank of England. (Click here for a PowerPoint of the chart.)

What lies ahead for economic growth in 2013 and beyond? And what policies should governments adopt to aid recovery? These are questions examined in four very different articles from The Guardian.
The first is by Nouriel Roubini, Professor of Economics at New York University’s Stern School of Business. He was one of the few economists to predict the collapse of the housing market in the USA in 2007 and the credit crunch and global recession that followed. He argues that continuing attempts by banks, governments and individuals to reduce debt and leverage will mean that the advanced economies will struggle to achieve an average rate of economic growth of 1%. He also identifies a number of other risks to the global economy.
In contrast to Roubini, who predicts that ‘stagnation and outright recession – exacerbated by front-loaded fiscal austerity, a strong euro and an ongoing credit crunch – remain Europe’s norm’, Christine Lagarde, head of the IMF and former French Finance Minister, predicts that the eurozone will return to growth. ‘It’s clearly the case’, she says, ‘that investors are returning to the eurozone, and resuming confidence in that market.’ Her views are echoed by world leaders meeting at the World Economic Forum in Davos, Switzerland, who are generally optimistic about prospects for economic recovery in the eurozone.
The third article, by Aditya Chakrabortty, economics leader writer for The Guardian, looks at the policies advocated at the end of World War II by the Polish economist, Michael Kalecki and argues that such policies are relevant today. Rather than responding to high deficits and debt by adopting tough fiscal austerity measures, governments should adopt expansionary fiscal policy, targeted at expanding infrastructure and increasing capacity in the economy. That would have an expansionary effect on both aggregate demand and aggregate supply. Sticking with austerity will result in continuing recession and the ‘the transfer of wealth and power into ever fewer hands.’
But while in the UK and the eurozone austerity policies are taking hold, the new government in Japan is adopting a sharply expansionary mix of fiscal and monetary policies – much as Kalecki would have advocated. The Bank of Japan will engage in large-scale quantitative easing, which will become an open-ended commitment in 2014, and is raising its inflation target from 1% to 2%. Meanwhile the Japanese government has decided to raise government spending on infrastructure and other government projects.
So – a range of analyses and policies for you to think about!
