TL;DR: Japan’s top currency diplomat Masato Mimura warns markets that the yen’s slide is “very clear” and could worsen, urging swift policy action.
The Details
Mimura told Reuters the yen’s depreciation against the dollar is unmistakable. He warned that without coordinated monetary or fiscal response, the yen could fall further, pressuring import costs and inflation. The statement comes as the BOJ remains dovish and the government debates intervention. Traders have already seen USD/JPY breach 155, and the warning could spark short‑term volatility in forex and risk‑off assets.
Watch For
- Possible BOJ policy shift or government intervention in the FX market.
- USD/JPY breaking key psychological levels (e.g., 158).
- Impact on crypto pairs quoted in JPY as investors seek hedges.
