The yen slumped to its weakest level since 1989 this month on a real trade-weighted basis, driven in part by the continued popularity of the “ carry trade “,where investors borrow in currencies with low interest rates to invest in higher-yielding assets elsewhere.
Appetite for the trade underscores investors’ continuing willingness to take on risk. However, analysts warn the yen may be vulnerable to a correction if this trade unwinds. There has been a massive buildup of “short” positions betting on a fall in the yen. Short positions on the Chicago Mercantile Exchange, often used as a proxy for hedge fund activity, hit record levels in October.
The International Monetary Fund said last month there was strong evidence that Japanese domestic investors were conducting a form of carry trade by purchasing foreign bonds to support yen-denominated liabilities on an unhedged basis.
Adrian Hughes, currency strategist at Societe Generale, said if the carry trade unwound it might trigger another bout of risk aversion. “The recent uptrend in dollar/yen could easily reverse,” he said. “It is a matter of timing for this trade and it may be sooner than later for a turn lower in dollar/yen.”
Boutは発作とか勝負といった意味。 New bout of inflation は インフレの再燃と訳すようだ。
With the Japanese economy emerging from six years of deflation , both the Bank of Japan and Japan’s ministry of finance have said they are monitoring the situation, though most officials say a violent jump in the yen is unlikely.
The BOJ said it was impossible to put an accurate figure on the magnitude of the carry trade, and estimated outstanding carry trade positions at anything between \8,000 bn ($68bn) and \15,000bn. Officials said that, while large, this was not on a sufficient scale to cause a huge appreciation of the yen.
The potential of the carry trade as a source of future exchange rate volatility has brought back memories of October 1998 when the yen collapsed against the dollar as hedge funds unwound carry trades in response to the Russian financial crisis.
Derek Halpenny, senior currency economist at Bank of Tokyo-Mitsubishi UFJ, said it made sense that Japan’s authorities might have concerns given what happened in 1998. “That move clearly exacerbated Japan’s deflation problems,” he said.
