By the numbers
Market Impact and Official Response
Following the announcement, the yen surged more than 1 per cent to 155.20 per dollar, moving away from the 40-year low of near 164 reached last month. US Treasury Secretary Scott Bessent expressed support for Japan's steps to correct the yen's undervaluation and confirmed Washington's willingness to participate in future joint efforts. Japan's Finance Minister Satsuki Katayama stated that the government will continue to align currency policy with the Bank of Japan.
Policy and Economic Context
The intervention follows Japan's solo market actions earlier in the year and a June rate hike by the Bank of Japan, which had limited success in stabilizing the currency. Markets are now pricing in a potential interest rate hike by the Bank of Japan as early as September. Additionally, the US indicated it may increase the size of a Federal Reserve repurchase facility to provide temporary dollar liquidity to Japan, a tool intended to assist with market stability.
