TOKYO, May 1 (Reuters) – Japan may have spent as much as 5.48 trillion ​yen ($35 billion) bolstering its embattled currency, ‌central bank data indicated on Friday, following reports that Tokyo intervened on Thursday to arrest a sharp selloff in the yen.

The Bank of ‌Japan’s ​projection for money market ⁠conditions on May ⁠7, the next market day after a stretch of domestic holidays, indicated a 9.48 trillion yen net outflow of funds.

Major ​money market firms had forecast a drawdown of between 4 trillion yen ⁠and 4.5 trillion yen.

Yen-buying ⁠activity involves the BOJ soaking up ​yen from markets, so any outsized shortfalls in ​funds can offer potential clues as ‌to how much was spent on any intervention.

Japan intervened to support the yen against the U.S. dollar on Thursday, sources ⁠familiar with the matter told Reuters, in its latest attempt to halt a slide exacerbated by ⁠a ‌spike in oil prices linked ⁠to the Iran war.

Prior to ​that, ‌Japan’s most recent intervention happened in ​July ⁠2024, when it spent about $36.8 billion to bolster the yen after it sank to a 38-year low of 161.96 per dollar.
