The Japanese yen strengthened to its highest level in three months following confirmation that the United States and Japan executed a rare joint intervention in foreign exchange markets late last week.
The coordinated action represents a significant escalation in efforts to curb the yen's volatility, with US President Donald Trump describing the move as a "signal of friendship" intended to benefit both economies.
The currency pair USD/JPY retreated sharply as traders digested the news of the bilateral operation.
The intervention comes amid ongoing pressure on the yen, which has faced sustained selling pressure in recent months.
By acting jointly, Washington and Tokyo signaled a unified front against excessive market fluctuations, a strategy that typically carries more weight than unilateral measures.
This development follows previous instances of Japanese authorities intervening independently to support the currency.
