For the past three years the Japanese yen has been appreciating against the US dollar and many other currencies. From the end of June 2007 to 14 September 2010, the yen appreciated from ¥100 = $0.81 to ¥100 = $1.20 (a 48% appreciation). Over the same period the yen exchange rate index rose from 113.3 to 172.4 (a 52% appreciation). The rising yen has been impeding Japan’s recovery as it has made its exports more expensive, while, at the same time, making imports cheaper and thus making it harder for domestic firms to compete.
Until 14 September 2010, the yen was freely floating. But on 15 September, the Japanese central bank decided to intervene by selling yen and buying dollars and other currencies.
But why had the yen risen so strongly? There are four main reasons.
The first is the persistent Japanese trade surpluses, partly stimulated by falling costs of production in Japan.
The second is the unwinding of the carry trade. Before the banking crisis of 2007/8, many banks and other financial institutions borrowed yen, given the low interest rates in Japan, and used the yen to purchase dollars and pounds, given the much higher interest rates in the USA and the UK. The effect of this ‘carry trade’, as it was known, was to drive up the exchange rates of the dollar and sterling and drive down the value of the yen. This encouraged further speculation as people sold yen in anticipation of further depreciation and purchased dollars and sterling in anticipation of further appreciation. With the banking crisis, however, short-term financial flows decreased and the current account became more important in determining exchange rates. The carry trade began to unwind and people began selling dollars and sterling and buying yen. What is more, towards the end of 2008, interest rates were reduced substantially in the USA and the UK in order to stimulate aggregate demand. The interest rate differential between Japan and the USA and UK virtually disappeared. This further encouraged the purchase of yen and the sale of dollars and sterling as carry trade investors began paying back their loans to Japan.The third reason for the appreciation of the yen is the actions of the Chinese who have used their surpluses to buy other currencies: originally mainly dollars, but increasingly yen.
The fourth reason is speculation. As the yen has risen, so increasingly people have bought yen in anticipation of further appreciation. But, of course, this speculation has brought about the very effect the speculators anticipated. Such speculation can be very powerful, given that some $4 trillion goes across the foreign exchange markets every day (see The inexorable growth of FOREX).
So will the intervention by the Bank of Japan be successful in causing the yen to depreciate? Or will the forces that drove up the yen prove impossible to resist? The following articles consider this question and also look at the factors that caused the yen to appreciate and its effects on the Japanese economy.

Questions
- Why has the Japanese yen appreciated so much over the past three years?
- What will be the effect of the Bank of Japan’s exchange market intervention on Japanese money supply? What will determine the size of this effect?
- Why might the Bank of Japan’s actions have been influenced by the anticipation of further quantitative easing by the US Federal Reserve Bank?
- What factors determine the likely success of foreign exchange market intervention by central banks?
- What will determine how speculators will react to the Bank of Japan’s actions?
- Discuss the following quote from the second The Economist article above: “A bit of inflation in Japan wouldn’t just be a good thing. It would be a really, really great thing. And if other countries react to Japan’s intervention by attempting to print and sell their own currencies in order to toss the deflationary potato to someone else, well then so much the better.”
- If all countries seek to achieve export-led growth, is this a zero-sum game?

Every three years the Bank for International Settlements (the central bankers’ central bank) publishes a survey of foreign exchange market activity. The latest survey has just been published. Despite the banking crisis and subsequent recession, foreign exchange market turnover has increased by nearly 20% since 2007. The daily average value of currencies traded on the foreign exchange market is now $3.981 trillion. In 2007 it was $3.324 trillion and in 2001 it was just $1.239 trillion.
According to the BIS press release:
• The increase was driven by the 48% growth in turnover of spot transactions, which represent 37% of foreign exchange market turnover. Spot turnover rose to $1.5 trillion in April 2010 from $1.0 trillion in April 2007.
• The increase in turnover of other foreign exchange instruments was more modest at 7%, with average daily turnover of $2.5 trillion in April 2010. Turnover in outright forwards and currency swaps grew strongly. Turnover in foreign exchange swaps was flat relative to the previous survey, while trading in currency options decreased.
• As regards counterparties, the higher global foreign exchange market turnover is associated with the increased trading activity of “other financial institutions” – a category that includes non-reporting banks, hedge funds, pension funds, mutual funds, insurance companies and central banks, among others. Turnover by this category grew by 42%, increasing to $1.9 trillion in April 2010 from $1.3 trillion in April 2007. For the first time, activity of reporting dealers with other financial institutions surpassed inter-dealer transactions (i.e. transactions between reporting dealers).
• Foreign exchange market activity became more global, with cross-border transactions representing 65% of trading activity in April 2010, while local transactions account for 35%.
• The percentage share of the US dollar has continued its slow decline witnessed since the April 2001 survey, while the euro and the Japanese yen gained relative to April 2007. Among the 10 most actively traded currencies, the Australian and Canadian dollars both increased market share, while the pound sterling and the Swiss franc lost ground. The market share of emerging market currencies increased, with the biggest gains for the Turkish lira and the Korean won.
• The relative ranking of foreign exchange trading centres has changed slightly from the previous survey. Banks located in the United Kingdom accounted for 36.7%, against 34.6% in 2007, of all foreign exchange market turnover, followed by the United States (18%), Japan (6%), Singapore (5%), Switzerland (5%), Hong Kong SAR (5%) and Australia (4%).
The following articles look at some of the details of the report and consider their implications for London and for the global economy: an economy that has grown (in money terms) by 82% since 2001, while exports have grown by 101% and foreign currency transactions by 221%.

According to GDP figures released on 15 August, China overtook Japan in the second quarter of 2010 to become the world’s second largest economy. This raises two questions: just what do the GDP figures mean and why has this happened?
The GDP figures are total figures measured in US dollars at current exchange rates. According to these nominal figures, Japan’s GDP was $1.286 trillion in the second quarter of 2010; China’s was $1.335 trillion. This follows several years when Chinese growth rates have massively exceeded Japanese ones.
As far as explanations are concerned, economists look to a number of different factors, including investment policies, relative exchange rates, confidence, deflation in Japan and the scope for catching up in China.
The following podcasts and webcasts look at these questions, as do the articles.

’The steepest and longest recession of any developed country since World War II.’ This has been the case for Ireland, which has seen national income fall by 20% since 2007. Many countries across the globe have experienced pretty bad recessions, but what makes Ireland stand out is how it has been dealt with.
In the UK, the government has continued spending in a bid to stimulate the economy and to use Gordon Brown’s phrase from 2008, we have aimed to ‘spend our way out of recession’. Ireland, however, did not have that option. With too much borrowing, Ireland was unable to stimulate the economy and needed to cut its debts in order to maintain its credibility in the eurozone. Last year, significant cuts in government spending were accompanied by tax rises equal to 5% of GDP. Similar action is to be expected in the UK following the election, where popular benefits may have to be reduced, as transfer payments do account for the majority of government spending. Whoever is in government following the election will have some hard decisions to make and everyone will be affected. Read the article below and listen to the interview and think about what the UK can learn from Ireland.
Irish lessons for the UK (including interview) BBC Stephanomics (9/4/10)
Questions
- In the interview, Brian Lenihan said that the UK was expecting too much from the falling value of sterling. What was the UK expecting following significant depreciations in the value of sterling and why has that not happened?
- What is a deflationary spiral? Why has it caused Ireland’s public debt to rise so much?
- Why does Brian Lenihan argue that there are limits to how much taxes can be increased? What are diminishing returns to taxation?
- Would the UK be any better off had we joined the euro? What about other countries: would they have benefited had we joined the euro?
From the end of January to the beginning of March, the sterling exchange rate index fell by over 6% – from 81.7 to 76.5. Against the dollar, the fall has been even more dramatic, falling from $1.62 to $1.49 (a fall of 8%). What are the reason for this? And is the depreciation likely to continue? The following clip looks at what has been going on and whether the reasons are political, or whether there are other economic fundamentals that have contributed to sterling’s fall.
