The Great Unraveling of the Yen Carry Trade

The Great Unraveling of the Yen Carry TradeThe yen carry trade became all the rage among investors and speculators, but by 2006, some experts began warning of the dangers that could arise if and when these carry trades were reversed or "unwound." These warnings went unheeded. The global credit crunch that developed from August 2007 led to the gradual unraveling of the yen carry trade. A little over a year later, as the collapse of Lehman Brothers and the U.S. government rescue of AIG sent shockwaves through the global financial system, the unwinding of the yen carry trade commenced in earnest. (For more insight, see How does a credit crunch occur?)Speculators began to be hit with margin calls as prices of practically every asset began sliding. To meet these margin calls, assets had to be sold, putting even more downward pressure on their prices. As credit conditions tightened dramatically, banks began calling in the loans, many of which were yen-denominated. Speculators not only had to sell their investments at fire-sale prices, but also had to repay their yen loans even as the yen was surging. Repatriation of yen made the currency even stronger. In addition, the interest rate advantage enjoyed by higher-yielding currencies began to dwindle as a number of countries slashed interest rates to stimulate their economies.

The yen rose as much as 29% against the euro in 2008. By February 2009, it had gained 19% against the U.S. dollar since September, rising to a 13-year high of about 90.
