The U.S. Energy Information Administration has revised its view on global oil supply, concluding that OPEC can produce more oil than previously believed. In its December outlook, the agency updated how it measures production capacity, lifting estimates of OPEC’s effective capacity across 2024–2026 without any new barrels being added.
The change reflects a clearer distinction between theoretical maximum output and the volume that can realistically be brought online within 90 days and sustained. As a result, OPEC’s estimated spare capacity has increased, suggesting the oil market is less vulnerable to supply disruptions than traders had assumed.
The revision slightly weakens OPEC+ claims of tight capacity and signals a more resilient supply backdrop, reducing upward pressure on oil prices.
