US equity markets began September under pressure as futures contracts slipped Tuesday morning. Investors grappled with a confluence of challenges including surging crude prices, elevated bond yields, and mounting expectations that the Federal Reserve will deliver another rate increase.
Futures tied to the Dow Jones Industrial Average retreated 0.7%, with S&P 500 contracts declining approximately 0.3%. Contracts linked to the Nasdaq-100 fell 0.1%. The weakness extended Monday’s losses across all three benchmark indices.

While September opened with selling pressure, equities concluded August with robust double-digit percentage gains for the year. Technology sector strength in August helped offset July’s steep declines.
Middle East Hostilities Drive Energy Prices Higher
Escalating conflict between Washington and Tehran has emerged as a primary catalyst for market volatility. The two nations reengaged in military operations over the weekendātheir first confrontation in a monthātriggering a sharp spike in energy prices.
Brent crude contracts are hovering around $90 per barrel. The strategically vital Strait of Hormuz continues to experience severe disruptions, with maritime traffic operating at minimal capacity compared to pre-conflict levels.
The United States tightened economic sanctions against Iran last week, further diminishing prospects for diplomatic resolution in the immediate future.
Rising oil prices amplify inflationary pressures throughout the economy. This development compounds challenges facing Federal Reserve policymakers as they navigate monetary policy decisions.
Market Prices In Higher Probability of September Rate Increase
Derivative markets now indicate a 64.4% likelihood that the Federal Reserve will implement a 25 basis point rate hike at its September policy meeting. This represents a substantial increase from the 42.7% probability registered just seven days earlier, based on CME FedWatch data.
The recalibration followed Federal Reserve Chair Kevin Warsh’s address at last Friday’s Jackson Hole economic symposium. While Warsh emphasized the central bank’s dedication to achieving its 2% inflation objective, he refrained from explicitly previewing a rate adjustment.
Yields on 10-year Treasury securities climbed to 4.75%, maintaining downward pressure on equity valuations. Higher yields increase capital costs for businesses and typically compress stock price multiples.

Tuesday brings the Job Openings and Labor Turnover Survey, while Friday’s employment report will provide crucial labor market insights. Manufacturing metrics from S&P Global and the Institute for Supply Management are also scheduled for release.
