Asian Markets Rise Amid U.S.-Iran Standoff and Vessel Attack

Asian stock markets mostly closed higher on August 4, 2026, supported by strong U.S. manufacturing data. However, volatility persisted due to geopolitical tensions and a projectile strike on a cargo vessel near Al Khasab, Oman, which drove Brent crude futures toward $85 a barrel.

A diplomatic stalemate continues between the United States and Iran. While the U.S. President asserts that negotiations are underway and that Iran has a "last chance" to reach an agreement, Tehran denies engaging in direct talks with Washington. Iranian officials maintain that their current discussions are exclusively with the Government of Oman to secure safe navigation through the Strait of Hormuz.

Financial stability concerns also emerged after U.S. Treasury Secretary Scott Bessent urged the Federal Reserve to expand its FIMA Repo Facility to support currency interventions by Japan. This request sparked concerns regarding the independence of the central bank. In response to the broader market instability, South Korean Finance Minister Koo Yun-cheol vowed to implement measures to curb stock market volatility.
