# Yen Weakens 1%, Erases Half of Intervention Boost 2026-08-10T06:16:15+00:00 | World & Diplomacy | Indian Opinion Desk Corroboration: 1 independent outlet The yen weakened as much as 1% to touch 159.35 per dollar on Monday, erasing half of the gains from the historic US-Japan joint intervention in late July. Authorities spent an estimated $34 billion on July 31 and $53 billion the previous day, the largest single-day intervention on record if confirmed. Yet the boost has faded quickly. Goldman Sachs strategists say depreciation pressures will reemerge without a shift in global conditions or a policy surprise. The Bank of Japan's July meeting summary flagged rising inflation risks, with one board member hinting at faster rate hikes. Traders remain alert for further official action, especially during Japan's Obon holiday when thin liquidity could invite another intervention. ## Coverage - livemint.com - livemint.com Tags: Bank of Japan, currency intervention, dollar-yen, forex, Japan, yen Canonical: https://indianopinion.org/yens-august-dip-tests-japans-intervention-resolve/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
