Yen Intervention Fears Mount After Takaichi Warning, Fed Rate Checks

Markets are on high alert for potential Japanese yen intervention this week after Prime Minister Sanae Takaichi warned of action against "abnormal" moves on January 25. Speculation intensified after the Federal Reserve Bank of New York contacted banks about the yen's exchange rate late last week, seen as a possible precursor to coordinated action. The yen rallied sharply on January 23, gaining 1.75% to 155.63 per dollar—its biggest one-day gain since August—as short positions were squeezed. Officials have previously intervened around the 160 level, spending nearly $100 billion in 2024. The warning comes ahead of a snap lower house election scheduled for February 8, with recent fiscal promises already roiling Japanese government bond markets.
