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.

- 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.”

Fears of growing debt problems in the EU have caused global stock markets to plummet. On 25th May, the FTSE was down by 2.6%, Germany’s Dax index fell by 2.34% and in France the Cac 40 was also down 2.74%. Shares across Asia fell, including those in Australia, Hong Kong, Japan and Thailand. On top of this, there are concerns of rising military tensions between North and South Korea. This has only added to the pessimism of investors.
Then came the rescue of the Spanish bank Cajasur by the Bank of Spain, which did little to restore confidence in the world economy. The Spanish deficit has reached 11% of GDP, which is nearly 4 times higher than eurozone rules allow. Spain is also suffering from unemployment of more than 20%, which has led the IMF to call for massive structural reform in the country. The euro has also weakened, as investors sell the currency, because of growing fears of debt default amongst the eurozone countries.
Amid concerns of possible default by Greece, Spain and other countries, the IMF and the members of the European Union have agreed an emergency package of €750 billion (£650 billion). €250 billion comes from the IMF, with €440 billion available as loan guarantees for struggling nations and €60 billion from emergency European Commission funding. We can only wait to see how effective this rescue package will be in restoring confidence in the Eurozone economies.

’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.

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.

The demise of the dollar as the world’s reserve currency has been predicted for a long time now. Yet it is still way surpasses other currencies, such as the euro and yen, as the main reserve currency of most countries. Also it still dominates world trade with much of international trade being priced in dollars. Indeed, as the eurozone reeled from the Greek debt crisis in early February (see A Greek tragedy and Debt and the euro) so investors sold euros and bought dollars. The dollar gained 12 per cent against the euro from December 2009 to February 2010 (from $1 = €0.66 on 1/12/09 to $1 = €0.74 by mid February).
But a number of economists, investors and officials argue that the dollar’s dominance is gradually being eroded:
As the United States racks up staggering deficits and the center of economic activity shifts to fast-growing countries such as China and Brazil, these sources fear the United States faces the risk of another devaluation of the dollar. This time in slow motion – but perhaps not as slow as some might think. If the world loses confidence in U.S. policies, “there’d be hell to pay for the dollar … Sooner or later, the U.S. is going to have to pay attention to the dollar”, [said Scott Pardee, economics professor at Vermont’s Middlebury College and formerly on the staff of the New York Fed].
So what is likely to be the future of the dollar? Will it remain the number one world reserve currency? Will its position be gradually, or even rapidly eroded? What will happen to the exchange rate of the dollar in the process? Finally, what is the significance of the trade and budget deficits in the USA? Are these of benefit to the rest of the world in providing the necessary dollars to finance world trade and investment? Or are they a source of global imbalance and instability? The following article look at these issues.

- What alternatives are there to having the dollar as the world’s main reserve?
- Does it matter if China holds $2.3 trillion in foreign exchange reserves, with nearly $800 billion in US Treasury debt?
- Why is the value of its currency a less urgent problem for the USA ‘than it would be for other borrowers who borrow and pay for imports with dollars’?
- What are ‘currency swap accords’ and why are they important for China?
- What are the implications of the Chinese yuan being undervalued against the dollar by as much as 40%?
