Finance Minister Satsuki Katayama told reporters in Tokyo on Monday that Japanese authorities are prepared to respond if currency market movements become disorderly, acting under a standing pact with her US counterpart. “If there are disorderly movements or excessively speculative moves, we will take action,” she said, adding that Tokyo has been coordinating and holding discussions with the United States quite frequently and expects to continue responding that way. The warning follows official data last week showing Japan did not intervene in the currency market over the September to October period, and it comes a day before the US midterm elections.
Katayama warns Japan will act on disorderly yen moves
Finance Minister Satsuki Katayama said on Monday that Japan will act if currency moves turn disorderly or excessively speculative, under its standing pact with the United States.
Why it matters: Verbal warnings are the step Tokyo takes before intervening to buy yen, and this one lands a day before the US midterm elections, a window when thin, headline-driven trading can move the currency fast.
