Japan's Ministry of Finance is reported to have intervened twice in the foreign-exchange market during Golden Week, the first move on April 30 coming within minutes of the yen breaching the politically sensitive 160-per-dollar mark. A second, smaller intervention is believed to have followed on May 6 as Tokyo trading reopened.
Officials have not formally confirmed either operation, in line with longstanding ministry practice. Cross-checking BOJ current-account data against private flows points to interventions of roughly seven and three trillion yen respectively, totalling close to $65 billion.
The yen has weakened back toward 159 in the days since, leaving traders openly testing whether the ministry will defend the line a third time or accept a managed slide. The BOJ-Fed policy-rate gap remains wide; Bank of Japan governor Kazuo Ueda has said the path of policy normalisation will not be accelerated to support the currency.
Currency strategists at MUFG noted that the previous 2022 and 2024 intervention rounds bought Tokyo time rather than altering the trend; the durability of any move depends on whether the Federal Reserve cuts later in the year. The CME futures market currently prices a first cut in September.
The intervention has political resonance. Prime Minister Sanae Takaichi has retained strong approval numbers but voters consistently cite the cost of living — driven heavily by import-priced energy and food — as their top concern, and a weaker yen feeds directly into that complaint.
Friday's softer dollar provided some respite: the dollar index fell to 97.93 after a stronger-than-expected April US jobs print failed to lift Treasury yields. A continued slide in the dollar would do more to ease pressure on the yen than any single ministry operation.
Japanese exporters, meanwhile, have spent the week locking in hedges, judging that the ministry is more likely to smooth volatility than reverse it. The next significant level on the chart is 162; below 158, traders say a managed period of consolidation looks possible.
