The Yen's rise suggests that the pace of "financial de-leveraging" is accelerating. The global financial crisis seems to have brought a sudden end of one of the world’s biggest easy-money schemes, the so-called yen-carry trade.
The Japanese economy never really recovered after the collapse 20 years ago. To stimulate the economy the Bank Of Japan lowered interest to the point that effectively interest rate in Japan went to zero. Also, the Japanese are a frugal lot, amassing savings to the tune of trillions of dollars.
For much of this decade, Japanese and foreigners alike borrowed money in Japan and invested that money in higher yielding assets across the world, from home loans in America to equities in Mumbai. This turned Japan, with its $15 trillion in personal savings built into a provider of low-cost capital for the rest of the world.
No one knows for sure how large this outflow was. Much of the yen-carry trade took place beyond public scrutiny, in the form of currency options or other types of derivatives trading. Its size is believed to have been to the tune of hundreds of billions of dollars per year. Some of the biggest players in the carry trade were American and European hedge funds and banks. But Japanese individuals also fed the outflow of yen by pouring their savings into overseas investments, like emerging markets funds, in search of higher returns.
A simple example of the yen-carry trade is:
- Borrow Japanese Yen at the rate of say 1%pa and convert the money into US Dollar.
- Invest that money in a fund operated by a Singapore/ Hong-Kong based FII(Foreign Institutional Investor) who is allowed to buy/sell shares in India. The FII converts the dollars to rupees and buys shares of companies listed on the Bombay Stock Exchange. Assume that in 1 years time, the shares have increased in value by 20%.
- Sell the shares, convert the rupees to dollars and the dollars to Yen. Repay the borrowed money with interest. Pocket the difference of 19%.
I don't know how/when the crisis will be resolved. However one thing is clear: Huge currency speculation of the kind that made the currency carry trade a cornerstone of global finance in recent years is highly destabilizing. When this crisis is over, the authorities should aim to reduce it.
