Japan's FX chief signals intervention readiness as yen weakens.

Japan's FX chief signals intervention readiness as yen weakens. Vice Finance Minister Atsushi Mimura warned Monday that authorities may take bold action if speculative activity in currency and crude oil futures markets continues. His remarks, the strongest warning yet, helped strengthen the yen to 159.74 after it had weakened past 160 per dollar earlier in the morning. This level marks the first time since Japan's intervention in July 2024 that the yen approached this threshold. Bank of Japan Governor Kazuo Ueda reinforced concerns in parliament, noting the central bank could implement larger-than-usual rate hikes depending on geopolitical developments. Analysts remain divided on whether Japan will intervene directly or continue attempting to manage markets through verbal guidance alone.
