Overview
Japanese officials are suspected of spending about $34.5 billion on currency-market operations on Thursday to support the yen, according to an analysis by Bloomberg that compared Bank of Japan accounts with forecasts from money brokers. The suspected operation followed a fall in the yen to 160.72 against the US dollar, a level described as the currency's weakest since mid-2024, after which the yen staged a sharp reversal.
Scope and context of the suspected intervention
The Bloomberg comparison indicates an estimated outlay of roughly 5.4 trillion, a sum that would exceed the average 53.8 trillion spent during four separate interventions in 2024. If the estimate proves accurate, the move would be Japan's first direct market intervention since July 2024.
Political and official reactions
The suspected action would be the initial intervention under Prime Minister Sanae Takaichi and Finance Minister Satsuki Katayama, a sign that the new administration's approach to yen weakness may be consistent with previous policy precedents. Japan's top currency official, Atsushi Mimura, declined to comment on Friday when asked about the suspected market activity. Separately, a source familiar with the matter confirmed to Bloomberg that the government did intervene.
What is known and what remains uncertain
The Bloomberg analysis rests on a reconciliation of central bank account data and broker forecasts; while the comparison points to a significant outlay, final confirmation from official channels remains limited. The report frames the figure as an estimate and notes that confirmation would make this the first intervention since July 2024. Officials have not provided public detail beyond the comments noted above.
