Japanese Finance Minister Satsuki Katayama warned of imminent foreign exchange intervention as the yen neared the critical 160-per-dollar threshold. Speaking at a press conference, she cited rising speculative activity and significant volatility in currency markets as threats to public economic stability.

"We are prepared to respond fully on all fronts," Katayama said, underscoring government resolve. The yen’s rapid decline has intensified concerns in Tokyo, where past interventions have halted similar slides.

She declined to comment on the Bank of Japan’s monetary policy, stating that interest rate decisions remain under the central bank’s authority.
