进退两难的日元再度迎来“干预窗口”

Group 1: Yen Exchange Rate Dynamics - The yen appreciated by 2.6% to 154.2 yen/USD over two trading days following the Bank of Japan's (BOJ) meeting, driven by signals of potential "rate checks" from both the US and Japan[1] - Historical interventions by Japanese authorities typically follow "rate checks," suggesting a possible coordinated intervention could lead to further yen appreciation[2] - Since 2021, the average appreciation of the yen after interventions has been 1.4% within a week, indicating potential short-term gains from intervention[3] Group 2: Long-term Outlook and Risks - Historical data shows that interventions do not alter the long-term trend of the yen, which remains vulnerable to depreciation if the BOJ does not accelerate interest rate hikes[4] - The BOJ's delayed monetary policy has resulted in persistently low real interest rates, contributing to the yen's weakness[5] - Upcoming fiscal expansion measures, equivalent to 0.8% of Japan's GDP, may increase inflationary pressures, complicating the BOJ's policy decisions[5] - Risks include unexpected outcomes from the Japanese House of Representatives elections and inflation levels exceeding expectations, which could further impact the yen's stability[6]
