Overview
- Finance Minister Satsuki Katayama told parliament Tokyo can take "decisive action" at any time as the yen repeatedly tested the 160-per-dollar level, a threshold markets treat as a line that triggers intervention.
- Japan's foreign exchange reserves fell by a record $77.1 billion in May, Ministry of Finance data show, a drop officials say is consistent with large-scale yen-buying operations and reports of a roughly $73 billion late-April/May intervention.
- A stronger-than-expected U.S. jobs report that showed 172,000 payroll gains pushed the dollar higher on June 5 and briefly drove USD/JPY above 160, producing sharp intraday swings and raising the odds of further official moves.
- Analysts warn interventions can blunt sharp moves but are unlikely to reverse the multi-year downtrend without a sustained shift in fundamentals because U.S.-Japan yield and growth gaps keep flows into dollar assets.
- Practical limits are rising as officials fund support by reducing Treasury holdings, which could test U.S. tolerance, leading markets to watch for technical workarounds such as the Fed's FIMA repo and for upcoming BOJ policy steps that could change the outlook.
