Japan’s 14 trillion Yen currency defense in July erased 900 pips but the Yen has since surrendered over half those losses amid persistent USD strength.
The Dollar climbed to 159.50 Yen on Tuesday, nearing its highest level since Japan and the U.S. intervened in late July to prop up the currency. That joint operation, the first since 1998, spent nearly 14 trillion Yen to push the pair down from near 164.00 to 155.00, a 900-pip drop over two sessions.
Since then, the Yen has steadily weakened, regaining more than half of its intervention-driven losses. The recovery has been gradual, marked by narrow trading ranges—Tuesday’s 49-pip move was typical—rather than sharp reversals. No single catalyst has driven the shift, with higher session highs persisting through August.
Japan’s fiscal plans, including a proposed 1% consumption tax cut on food, lack identified funding, risking further inflation pressures. While Japanese government bond yields have risen, U.S. yields have kept pace, leaving the yield differential—and the USD/JPY pair—largely unchanged.
