Analysts cite limited foreign reserves and unclear Fed support as reasons for the yen’s failure to sustain gains post-intervention.
The Japanese yen has partially reversed gains following last week’s historic USD/JPY intervention, despite US Treasury involvement. The move, while large in scale, has not convinced markets of a sustained yen recovery, according to analysis.
Foreign exchange reserves are finite, and even the Bank of Japan’s vast holdings were insufficient for long-term currency defense in past attempts. While Fed participation theoretically provides unlimited dollar supply, doubts persist over the transparency and commitment of coordinated interventions.
Markets may soon test higher USD/JPY levels again unless authorities signal continued joint action. Treasury Secretary Scott Bessent’s stance remains a key factor in shaping expectations.
