Bank of Japan governor Haruhiko Kuroda just sent markets into a tailspin after dropping strong suggestions that the yen shouldn’t weaken much further against the dollar.

According to Reuters, Kuroda said that Japan’s real effective exchange rate is “very weak”, so further declines in the yen don’t seem likely.

The Japanese currency initially rose by more than 1.4% against the dollar.
