The immediate effect on the broader market was a notable divergence between commodity prices and equity valuations. While crude prices bounced back, energy stocks did not follow suit. The Energy Select Sector SPDR (XLE) declined by 3% to close at its lowest level since September 30. Major industry participants, including Exxon Mobil and Chevron, each slipped by approximately 2%, while services and infrastructure firms Baker Hughes and Williams fell in line with the general market downturn. Despite this recent pullback, the XLE remains the best-performing sector of 2026, up approximately 40% year-to-date, though it has dropped 12% from its October 30 high over the last four sessions.
Market dynamics in 2026 have been characterized by an unusual inverse relationship between oil and equities. According to Yahoo Finance calculations, oil and the S&P 500 have moved in opposite directions more frequently this year than in any year since at least 2001. The daily correlation between the two indices stands at -0.44, significantly lower than the previous record of -0.25 recorded in 2003, the year of the US invasion of Iraq. This trend suggests that rising oil prices have acted as headwinds for stocks, while falling prices have served as tailwinds. On November 4, for instance, the S&P 500 rose more than 1.5% as crude prices fell over 8%, a pattern that reversed on Thursday.
Background factors influencing these movements include geopolitical tensions and shifting political sentiment. Iran’s crude exports have fallen from roughly 1.8 million barrels per day to essentially zero, according to a November 4 note from Apollo chief economist Torsten Sløk. Despite this supply shock, WTI is up more than 50% this year, retaining a significant war premium. Political commentary has begun to influence market perceptions of the conflict’s sustainability. Following the November 4 price drop, Vice President JD Vance posted on social media platform X, stating, “The reason we lost is the war.” Steve Sosnick, chief strategist at Interactive Brokers, noted on a Yahoo Finance morning show that the Vice President’s remarks likely reflect the views of a substantial portion of the Republican caucus, suggesting a potential shift in Washington’s appetite for the ongoing conflict.
The next phase of market movement will depend on how investors price in these political signals relative to the physical supply constraints. With Iran’s exports near zero and the benchmark still carrying a substantial premium, the divergence between the physical market and equity sentiment remains a key variable for traders to monitor in the coming sessions.
