Former Japan FX official Takehiko Nakao suggests Japanese authorities may intervene in the foreign exchange market to halt rapid yen weakening.

Former Japan FX official, Takehiko Nakao, says Japanese authorities could intervene in the foreign exchange market to halt rapid yen weakening "at any time" if excessive. The yen is hovering near a 34-year low against the dollar. Nakao, a former vice finance minister for international affairs, warns the weak yen significantly impacts household incomes and consumption, although it raises real-estate and stock prices.
