Mrs Watanabe, the market’s metaphor for Japan’s housewife yen speculators, has come back to life.” In other words, the Yen carry trade is back. Precise data remains elusive, as always, but several recent papers/articles have nonetheless succeeded in bringing some clarity to this growing, but murky, type of trading strategy. According to one source, “Monthly capital and financial account outflow rose to a nine-year high of ¥3.75 trillion in March, up from ¥1.93tn in February, according to Japan’s Ministry of Finance. Similarly, Japan’s Investment Trusts Association reported last week that Japanese investment trust holdings of foreign assets surged by ¥1.77tn ($15bn) in April to ¥32.3tn and are now up ¥4.57tn year-to-date. This is the biggest monthly increase since the monthly data began in 1989.”If it’s not already clear, allow me to spell it out. Japanese investors are collectively shorting their own currency, based on the expectation that it will neither appreciate suddenly nor fluctuate wildly so that they can earn profits from investing in higher-yielding alternatives. Research has showed (backed by common sense) that volatility is the main enemy of the carry trade. “When the carry-to-volatility ratio (i.e.,the ratio of the interest rate differentials to the volatility in the two currencies) increased through summer 2008 — in other words, when investors were able to make returns from the interest rate differentials under the low FX rate risk — they increased their positions to a remarkable degree.” On the flipside, “The reaction of the Japanese retail investors to the increase in financial market volatility (the VIX index measure of US equity market volatility is used as a proxy) was particularly apparent in October 2008 when investor positions were wound back sharply.”
