Elevated geopolitical tensions in the Middle East, including risks of renewed U.S. and Israeli strikes on Iran after the November 3 midterms, have driven WTI crude above $100 per barrel and Brent near $117 as of late October 2026, embedding a substantial risk premium. These levels position the oil ≥ $80 outcomes as near-certain through election day, with the combined Democratic Senate scenario priced at 67.3% reflecting trader consensus that sustained high energy costs amplify voter dissatisfaction and support Democratic gains in competitive races such as Ohio, Texas, Maine, and Alaska. The low probabilities assigned to oil < $80 scenarios (under 4% combined) underscore limited near-term de-escalation expectations, while Democratic Senate control edges ahead in the high-oil regime due to historical patterns linking energy inflation to midterm losses for the incumbent party. Key catalysts ahead include any diplomatic signals on the Strait of Hormuz and final polling shifts in toss-up contests.
