Oil prices steadied just above Thursday’s closing levels on Friday, August 14, 2026, as the possibility of a prolonged U.S. naval blockade of Iran returned supply risk to the center of trading. The modest rise followed a sharp pullback driven by softer demand projections and the largest increase in U.S. crude inventories in more than three and a half years.

Brent crude futures gained 0.2 percent to $87.24 per barrel by 9:30 UAE time. U.S. West Texas Intermediate crude advanced 0.31 percent to $81.50 per barrel. 

Both benchmarks remained on course for weekly gains of approximately 4 percent, even after falling more than 2 percent in the previous session. Thursday’s decline pared a six-session advance for Brent and a five-session rise for WTI.

Blockade pressure builds

The United States warned on Thursday that it could maintain its naval blockade of Iran indefinitely and increase economic pressure on Tehran as negotiations toward a ceasefire remained stalled. The statement strengthened concerns that a longer conflict could continue restricting crude supplies and commercial shipping.

U.S. Treasury Secretary Scott Bessent told Newsmax that further announcements were expected the following week. He indicated that Washington planned measures intended to impose a level of economic isolation on Iran that had not previously been attempted.

Iran has continued limiting traffic through the Strait of Hormuz, a passage that carried about 20 percent of the world’s oil before the conflict. The restrictions have lifted fuel prices and increased domestic pressure on U.S. President Donald Trump to end a war that Reuters described as unpopular at home.

Hossein Taeb, the recently appointed head of Iran’s Basij paramilitary organization, said the Strait of Hormuz remained under the Islamic Republic’s management and control, according to Iran’s semi-official Fars news agency.

Opposing forces balance

The prospect of an extended conflict constraining supply was offset by reduced oil-demand expectations from OPEC and the International Energy Agency. U.S. data also showed the largest weekly increase in crude stockpiles in more than three and a half years, reinforcing caution after the recent rally.

Tim Waterer, KCM’s chief market analyst, said the geopolitical and fundamental forces were acting as counterweights. In his assessment, they were keeping the market supported while limiting its ability to move decisively higher.

Two vessels belonging to the state-owned Abu Dhabi National Oil Company were attacked on Thursday while transiting the Strait of Hormuz, according to the UAE’s official WAM news agency. The UAE government condemned the incident as an Iranian attack.

Demand signals stay bearish

U.S. commercial crude inventories rose by 17.4 million barrels to 424.4 million barrels during the week ended August 7, their highest level since June 5. The increase was the largest since January 2023 and was driven in part by weaker exports, according to the latest inventory report. The build gave traders a substantial bearish counterweight to the risk that conflict could interrupt Middle Eastern supply, particularly after benchmark prices had advanced for several consecutive sessions.

The International Energy Agency’s August outlook projected global oil demand would decline by 1.6 million barrels per day in 2026, a contraction 510,000 barrels per day larger than it forecast one month earlier. The agency linked the revision to the continuing Hormuz closure and elevated fuel prices. It nevertheless forecast a 2.4 million-barrel-per-day rebound in 2027 and estimated the global market would record a 1.8 million-barrel-per-day deficit in the third quarter of 2026.

OPEC offered a less bearish consumption view in its monthly report, forecasting demand growth of approximately 600,000 barrels per day in 2026 after a slight downward revision. The producer group expects non-OECD consumption to increase by about 600,000 barrels per day while OECD demand eases by roughly 40,000 barrels per day. For 2027, OPEC projects global demand growth of approximately 2.2 million barrels per day, with non-OECD economies supplying most of the expansion.

Transit volumes remain

Physical shipping data continued to show constrained movement through the region’s key energy corridor. Nine commodity vessels crossed Hormuz on Thursday, up from five on Wednesday but below August’s daily average of 12, according to Kpler data. Five entered the Gulf and four exited toward the Gulf of Oman, with most using the Iranian shipping route. Some vessels may have traveled with transponders disabled and therefore were not included in the count.

The same data showed 19 commodity vessels passing through the Bab el-Mandeb Strait on Thursday with their transponders operating, compared with 20 one day earlier. Meanwhile, the IEA estimated global oil supply rose by 2.4 million barrels per day in July to 101.5 million barrels per day but remained 6.3 million below its year-earlier level. Gulf production was still 8.3 million barrels per day below prewar levels, underlining why shipping security continues to influence prices despite weaker consumption estimates. These figures highlight the pressure from restricted supply, rising costs and softer consumption.

Oil volatility persists

Oil’s latest stabilization followed several sessions in which diplomacy, vessel traffic and inventory data repeatedly changed the market’s direction. On August 10, benchmark prices climbed approximately 5 percent as uncertainty over reopening the Strait of Hormuz persisted. Traders treated the waterway’s status as the immediate test for whether disrupted Gulf supply could return more reliably to international buyers. 

By August 11, oil had reached roughly one-week highs as expectations for a U.S.-Iran agreement faded. Shipping traffic through Hormuz fell to six vessels, compared with a 10-day average of approximately 11, while Iran maintained that restrictions would continue until Washington changed its conduct. Supply concerns also extended beyond the Gulf after Libya’s National Oil Corporation warned that force majeure could become necessary if disruptions persisted, as detailed in Reuters’ August 11 coverage.
