Is coordinated currency intervention becoming the new tool for economic policy?
Core argument: Japan spent an estimated $53 billion in a single day to defend the yen—a likely all-time single-day record—dwarfing the sub-$1 billion U.S. contributions recorded in the 1998 and 2011 interventions.
It's still unclear how much Washington spent to help lift the yen from its four-decade low. But the currency’s rebound points at interventions larger than in 1998 and 2011, when US contributions didn’t surpass the $1 billion mark. Japan alone is estimated to have spent $53 billion on Thursday — a likely single-day record. Speculation is emerging of further joint moves. Expectations are rising for the Federal Reserve and Bank of Japan to raise interest rates in September, after the central bank in Tokyo held its benchmark rate on Friday but flagged inflation risks. Doubts over Prime Minister Sanae Takaichi’s big spending plans also raise the likelihood of renewed yen weakening, furthering the case for joint action.
