Japan's Finance Minister: U.S. Has Expressed Concerns Over Yen Weakness; Japan and U.S. to Coordinate Closely
nashnova research
Finance Minister Katayama Satsuki confirmed the U.S. raised concerns over the weak yen at the summit; USD/JPY fell 0.29% to 158.37 as markets priced in closer U.S.–Japan coordination on currency.
What exactly did the U.S. say?
Katayama said on September 25 that President Trump and U.S. officials explicitly raised concerns about yen weakness during the summit.
Japan pledged to coordinate closely with the U.S. on foreign-exchange matters.
This means → U.S. displeasure with yen depreciation has moved from market speculation to formal diplomatic communication, forcing Tokyo to respond publicly.
How did markets react?
The yen strengthened sharply after the announcement; USD/JPY dropped 0.29% to 158.37.
In plain terms = markets read this as a signal that the two sides may act jointly on the exchange rate — the risk of shorting the yen just jumped.
Will the Bank of Japan follow through?
Katayama stressed that specific monetary-policy tools are decided by the BOJ, not the government.
She added that the BOJ's recent rate hikes aim to achieve its inflation target, and she hopes the central bank will conduct appropriate policy while communicating with the government.
This means → the government is leaving the BOJ room, but the phrase "communicate and coordinate" is itself a form of implicit pressure — giving the BOJ one more external reason to hike.
What comes next?
Prime Minister Takaichi Sanae also expressed concern about yen weakness — the top-level message is unified.
Katayama said she would not comment on specific exchange-rate levels or rate checks — standard Finance Ministry language before intervention.
This reflects the fact that both sides' willingness to coordinate is now on the record, but whether actual policy action follows is what markets will price next.
