The story so far
written Oct 1What is happening
Global energy costs and industrial margins depend on the price of West Texas Intermediate (WTI) crude as supply constraints push Brent crude above $100 per barrel [5]. The U.S. Department of Energy offered to loan 40 million barrels from the Strategic Petroleum Reserve (SPR) on September 29, 2026, to mitigate supply shortfalls [1][2]. This release is the final portion of a 172-million-barrel international agreement [2]. The SPR currently holds fewer than 284 million barrels, its lowest level since 1982 [2].
Market pricing on Polymarket reflects a 52% probability that WTI will exceed $100 in October 2026. The probability of the price remaining below $90 is priced at 86%.
What to watch
A statement from the Energy Information Administration (EIA) regarding weekly petroleum status would confirm current U.S. inventory levels [16]. The International Energy Agency (IEA) warned on September 11, 2026, that the global supply gap will widen due to delays in restoring normal flows through the Gulf [4]. Future price movements depend on the resolution of shipping disruptions in the Bab el-Mandeb strait and the status of the U.S. blockade on Iranian exports [6].

How we got here
Brent crude prices reached $100 on September 9, 2026, following Houthi attacks on Saudi energy infrastructure and U.S. strikes on Iranian tankers [5]. The EIA reported that Brent averaged $91 in August 2026 [6]. OPEC+ members met on September 6, 2026, amid reports of 5.5 million barrels per day being shut in [7][13]. The IEA previously stated on September 11, 2026, that markets are straining to fill the gap left by Middle East supply shortfalls [3][4].

The U.S. Government offered to loan 40 million barrels of crude oil from the Strategic Petroleum Reserve (SPR) on September 29, 2026, marking the final batch of a 172-million-barrel international release agreement [2]. The SPR has reached its lowest level since 1982, containing fewer than 284 million barrels [2]. Brent crude surpassed $100 per barrel by September 9, 2026, following U.S. strikes on Iranian tankers and Houthi attacks on Saudi energy infrastructure [5]. The Energy Information Administration (EIA) reported that Brent averaged $91 in August, driven by a U.S. blockade on Iranian exports and shipping disruptions in the Bab el-Mandeb strait [6]. The International Energy Agency (IEA) warned on September 11, 2026, that the global supply gap will widen due to delayed returns of normal Gulf flows [4]. Polymarket currently prices the outcome for WTI crude hitting above $100 in October 2026 at 52%, while the outcome for it staying below $90 is priced at 86%.
