Market Impact

The ongoing U.S.-Iran conflict and Strait of Hormuz attacks are keeping oil prices elevated, adding inflationary pressure and uncertainty. Equity markets show resilience, with tech and financials favored, but the yen's intervention-driven gains may be temporary given fiscal and monetary policy concerns.

Event Summary

On August 4, 2026, global markets reacted to ongoing U.S.-Iran conflict, with oil prices rebounding after an attack on shipping near the Strait of Hormuz, underscoring doubts about a quick diplomatic resolution. European stocks and U.S. futures rose, while the yen eased after last week's coordinated intervention by U.S. and Japanese authorities. Brent crude rose about 1.5% to $85 a barrel. The S&P 500 hit a record high on Monday, and tech stocks led gains. Longer-dated U.S. Treasury yields remain near 19-year highs after Fed Chairman Kevin Warsh's comments. The yen remains about 4% stronger than pre-intervention levels, but concerns about Japan's fiscal policy and gradual BoJ rate hikes weigh. Analysts from Jefferies, Société Générale, Macquarie, and Eastspring provided market views.
