The Japanese yen has shown signs of stabilization following a series of government interventions aimed at curbing its rapid depreciation. On May 6, 2026, the yen surged to a 10-week high against the U.S. dollar, reaching ¥155.04, amid strong speculation of government action. The currency's sharp rebound from ¥157 followed suspected interventions totaling ¥4.5 trillion ($28.8 billion) during Japan's Golden Week holidays. Finance Minister Satsuki Katayama warned of 'decisive action' against speculative yen selling, while Japan's top currency diplomat confirmed no limits on intervention frequency. However, analysts question the durability of these measures as the yen's advance stalled near ¥155.The Japan Times+2
