Global oil prices rallied sharply this week as escalating tensions involving Iran, growing risks around the Strait of Hormuz, and weak supply outlooks from major producers pushed energy markets higher, despite signs of stable U.S. crude production and relatively balanced inventories.
Data released by Oilprice.com on May 15, 2026, showed Brent crude climbed to $108.92 per barrel, gaining $3.20 or 3.03 per cent, while U.S. West Texas Intermediate (WTI) rose to $104.76 per barrel after adding $3.59, representing a 3.55 per cent increase. Murban crude also advanced to $107.32 per barrel, reports Daily Independent.
The price rally reflects mounting concerns over possible disruptions in Middle East supply routes, particularly around the Strait of Hormuz, a strategic shipping corridor that handles a significant portion of global crude exports.
Market sentiment was further influenced by weak signals from the Xi-Trump summit, alongside lower demand projections issued by both the Organisation of Petroleum Exporting Countries (OPEC) and the International Energy Agency (IEA).
Despite the geopolitical premium driving prices upward, fresh U.S. production figures suggest the global market may still have some supply cushion.
Weekly U.S. oil production stood at 13.71 million barrels per day as of May 8, marginally lower than the previous week’s 13.723 million barrels per day.
Historical production trends in the report showed U.S. output remains near record highs, although slightly below 2025 levels.
Analysts say the stability in American shale production could help moderate excessive price spikes if geopolitical tensions worsen.
Meanwhile, U.S. commercial crude inventories declined to 452.9 million barrels from 457.2 million barrels recorded a week earlier, indicating continued drawdowns in stockpiles. However, inventory levels remain above some historical averages, suggesting there is no immediate supply shortage in the U.S. market.
Regional inventory data showed notable declines along the Gulf Coast, where stocks fell to 263.2 million barrels from 264.1 million barrels, while Cushing, Oklahoma — the delivery hub for WTI futures — recorded inventories of 27.4 million barrels.
The futures market also reflected expectations of sustained price strength. Front-month crude contracts traded above $91 per barrel across major benchmarks, underscoring investor expectations that geopolitical risks may continue to dominate short-term market direction.
Energy analysts warned that any escalation involving Iran or disruptions to shipping routes could trigger further volatility in oil markets, especially as traders closely monitor OPEC supply policy and global demand conditions in the coming weeks.
