European markets slip as hawkish Fed signals weigh on sentiment

U.S. stock futures experienced a decline early Monday due to heightened tensions between the United States and Iran, coupled with Federal Reserve Chair Kevin Warsh's hawkish remarks at the Jackson Hole symposium. The ongoing conflict between the two nations threatened oil prices, leading to a 2.5% increase in Brent crude to $90.31 a barrel and a 2.2% rise in U.S. West Texas Intermediate crude to $85.23.

Warsh's hawkish message boosted bets on a September interest-rate hike, increasing the probability of a 25-basis-point rate hike to 60% from 35% prior to his speech. The U.S. launched strikes against Iran on Larak Island in the Strait of Hormuz, a critical oil shipping route, while Iran retaliated by attacking two U.S. bases in Jordan.

Investors are now closely monitoring economic data for the week to determine if it will bolster Warsh's hawkish stance, as the July JOLTS report, August ADP private payrolls, and August ISM manufacturing data are all due. A strong labor market could allow the Fed to raise rates, while weak data might prompt more cautious policymaking.

Additionally, the United States continues to escalate financial pressure on Iran through Treasury Secretary Scott Bessent's warning of potential new secondary sanctions targeting Iranian banks and institutions, potentially disrupting global energy supplies and keeping oil prices elevated.
