Japanese Finance Minister Satsuki Katayama declined on Sunday to confirm whether Tokyo intervened in currency markets last week to support the yen, offering only limited remarks as she attended meetings in Samarkand, Uzbekistan.
Asked by reporters about reports that officials had stepped into the foreign-exchange market for the first time since 2024, Katayama said she was "not in a position to comment" at this stage. She did, however, note that "speculative moves have been continuing for some time."
The comments follow a spell of heightened volatility in the yen. The currency strengthened sharply on Thursday after earlier in the day sliding to a low of 160.72 per dollar. A Bloomberg analysis cited in reports suggests Japanese authorities likely expended roughly $34.5 billion in support of the currency.
Katayama also reminded market participants that Japan remains amid the Golden Week holiday period, when trading volumes tend to be thin and price swings can be more pronounced. Golden Week runs through Wednesday, leaving markets attentive to potential further moves before the holiday concludes.
Official Japanese figures released on Thursday evening confirmed that authorities had not intervened in the foreign-exchange market through April 27. That leaves a one-month window before the next official data release will reveal whether any action occurred in the latter half of the month.
The suspected operation followed public warnings from Katayama and top currency official Atsushi Mimura, who had urged market participants to refrain from excessive FX movements. Alongside Katayama, Bank of Japan Deputy Governor Ryozo Himino is attending regional gatherings, including the Asian Development Bank's annual meeting, as policymakers maintain a largely silent stance on the reports.
With officials offering no confirmation and official statistics not yet covering the entire period in question, investors and currency desks remain alert to continued uncertainty surrounding the scale and timing of any intervention. The estimated $34.5 billion suspected spending has become a focal point for traders managing yen exposure.
Summary
- Finance Minister Satsuki Katayama would not confirm suspected yen-support operations and described ongoing speculative moves.
- A Bloomberg analysis estimates about $34.5 billion may have been deployed in the suspected intervention.
- Official data through April 27 show no intervention, leaving a one-month gap before the next disclosure; Golden Week trading conditions may amplify volatility.
Context and market implications
Markets are weighing the suspected intervention against the backdrop of thin holiday liquidity. The lack of confirmation from officials, combined with the timing of the next official data release, maintains uncertainty for currency markets and participants who monitor FX policy signals closely.
