- Crude oil prices approached $90 per barrel following renewed US-Iran military confrontations
- Markets now assign a 64.4% probability to a September rate increase after Fed Chair Kevin Warsh’s Jackson Hole remarks

Financial markets opened September under considerable strain. Equity futures traded in negative territory Tuesday morning as market participants assessed surging energy costs, elevated bond yields, and mounting expectations for additional Federal Reserve tightening.
Dow Jones Industrial Average futures retreated 0.7%, S&P 500 futures declined approximately 0.3%, and Nasdaq-100 futures dropped 0.1%. These losses extended Monday’s session, which saw all three benchmark indices finish in the red.
Although September began on an uncertain note, equity markets concluded August with impressive double-digit gains for the year. Technology sector strength particularly contributed to these advances following a challenging July period.
Middle East Tensions Send Energy Prices Soaring
Escalating geopolitical friction between Washington and Tehran represents a primary catalyst behind current market anxiety. Military operations between the two nations recommenced Sunday after a month-long pause, propelling energy prices significantly higher.
BREAKING: Iran has just struck an oil tanker with 3 anti-ship cruise missiles in the US-backed southern Omani corridor while completing an outbound transit in the Strait of Hormuz under US escort, per UKMTO.
The vessel is the Saudi VLCC oil tanker “SIDR.”
ā The Hormuz Letter (@HormuzLetter) August 31, 2026
Brent crude contracts are hovering near the $90 threshold. The critical Strait of Hormuz waterway continues facing severe disruptions, with maritime traffic operating at substantially reduced capacity compared to pre-conflict volumes.
The United States additionally tightened economic restrictions against Iran last week. This development has diminished prospects for imminent diplomatic resolution in the region.
Escalating oil prices amplify inflationary pressures. This dynamic increases urgency for Federal Reserve intervention.
Market Pricing Shows Sharp Increase in Rate Hike Expectations
Traders now forecast a 64.4% likelihood that the Federal Reserve will implement a 25 basis point rate increase during its September policy meeting. This represents a substantial jump from the 42.7% probability recorded just seven days earlier, based on CME FedWatch data.
The recalibration followed Fed Chair Kevin Warsh’s address at Friday’s Jackson Hole economic conference. Warsh emphasized the central bank’s dedication to achieving its 2% inflation objective, though he refrained from explicitly previewing a rate adjustment.
The benchmark 10-year Treasury note yield climbed to 4.75%, maintaining downward pressure on equity valuations. Higher yields increase borrowing costs throughout the economy and typically compress stock price multiples.
The coming days feature several significant economic indicators that could influence market direction. Tuesday brings the Job Openings and Labor Turnover Survey, while Friday’s employment report represents the week’s marquee data release. Manufacturing indices from S&P Global and the Institute for Supply Management are also scheduled.
Corporate earnings announcements from Dell and Palo Alto Networks will provide insights into enterprise technology investment and cloud computing trends.
Historical patterns show September typically delivers the poorest performance for US equities among all calendar months, reinforcing the cautious positioning already evident among market participants.
