Going forward, the likelihood and scale of further moves to prop up the yen will depend on the pace of currency depreciation, market volatility and outright levels, Tanaka said. Japan holds about $1.2 trillion in foreign reserves as of the end of March, including $161.7 billion in foreign-currency deposits that can be used for intervention, with the remaining is held in foreign securities.
