Oil Price Today, August 19, 2026: WTI Nears $86 as Hormuz Attacks Revive Supply Fears

Key Takeaways

• WTI climbed to $85.70 and Brent reached $91.71 as crude advanced for a fourth straight trading session.
• Renewed ship attacks and conflicting claims about whether the Strait of Hormuz is open are restoring a geopolitical risk premium.
• Wider gasoline and diesel crack spreads are increasing concerns that the oil supply shock could feed into transport costs and inflation.

Oil Prices Extend Their Four-Day Rally

Oil prices extended their advance for a fourth consecutive session on Wednesday, August 19, as renewed attacks on shipping and contradictory statements about the Strait of Hormuz intensified fears of prolonged supply disruption. West Texas Intermediate crude rose 0.9% to $85.70 per barrel, while Brent crude gained 0.8% to $91.71 by 04:15 GMT.

WTI had traded between approximately $84.58 and $85.31 during earlier dealings before moving higher. Both benchmarks finished the previous session at their strongest levels in more than three weeks as optimism surrounding a possible US-Iran peace agreement faded.

The latest gains followed a significant change in market expectations. Earlier hopes that Washington and Tehran could extend their temporary agreement had reduced some of the geopolitical premium embedded in crude prices. However, that ceasefire expired on Monday without visible progress towards a permanent settlement.

US President Donald Trump said that no talks with Iran were taking place or scheduled. He also maintained that the Strait of Hormuz was open and that water mines had been cleared. Iranian officials presented a sharply different account, insisting that the waterway would remain closed until the United States met conditions contained in the June interim agreement.

Those conditions reportedly include lifting the blockade of Iranian ports, removing oil sanctions, releasing frozen Iranian assets and ending military operations. The contradictory statements leave shipowners without a clear indication that commercial vessels can safely resume normal operations.

The absence of diplomatic progress has therefore shifted attention back towards physical supply risks. Oil prices are reacting not only to statements from Tehran and Washington but also to evidence that ship movements through the region remain severely restricted.

Ship Attacks Raise the Hormuz Risk Premium

Security concerns intensified after Iran reportedly launched two ballistic missiles towards maritime traffic near the Strait of Hormuz. Air-defence systems in the UAE were activated, although both missiles ultimately landed in the sea. A separate attack damaged the engine room of a bulk carrier east of Oman.

These incidents followed earlier attacks on vessels attempting to navigate the strategic waterway. Shipping data showed that most operators continued to avoid Hormuz because there was no dependable confirmation that the route had reopened.

The scale of the slowdown illustrates why the market remains sensitive to every security development. On August 14, only two tracked vessels passed through the strait, compared with more than 130 ships per day before the conflict began in February. Some vessels may have travelled with tracking systems disabled, but recorded traffic remained far below normal levels.

Hormuz handled approximately 20 million barrels per day of crude and petroleum products in 2025, equivalent to around 25% of global seaborne oil trade. Its importance means even a partial disruption can affect tanker availability, insurance costs, freight rates and the price refiners pay for suitable crude grades.

UAE Suspends Trade and Financial Dealings With Iran

Regional tensions escalated further after the UAE suspended all trade, commercial exchanges and financial transactions with Iran until further notice. The decision followed the detection of two ballistic missiles that UAE authorities said were launched from Iran.

One missile reportedly landed outside UAE territorial waters, while the other fell within them. The incident prompted emergency alerts advising residents to seek shelter before authorities later declared that the immediate threat had passed.

The suspension does not automatically remove additional oil barrels from the market. However, it may reinforce the geopolitical premium by increasing commercial friction and making regional de-escalation more difficult.

The UAE is also an important energy producer, shipping hub and financial centre. Any escalation involving its territory can therefore have wider implications for tanker operations, maritime insurance and energy infrastructure throughout the Gulf.

Rising Crack Spreads Add to Inflation Concerns

Crude prices are not the market’s only concern. Gasoline and diesel crack spreads—the difference between crude oil prices and the value of refined fuels—have also widened. Higher crack spreads generally indicate tight supplies of finished petroleum products and stronger refining margins.

The US Energy Information Administration expects crack spreads to remain elevated through the end of 2026. Refined-product markets have tightened because of reduced Russian exports, disruption to shipments from refineries in Saudi Arabia and Kuwait, and lower refinery activity in China.

This means retail fuel prices could remain under upward pressure even if crude oil temporarily stabilises. More expensive diesel can raise road freight, agricultural and industrial costs, while higher gasoline and jet-fuel prices affect household spending and travel.

The development does not guarantee an immediate rise in headline inflation. Nevertheless, persistent strength in crude and refined fuels could complicate expectations for interest-rate cuts, particularly if higher energy costs begin spreading through transport and goods prices.

Alternative Oil Export Routes Offer Partial Relief

Gulf producers are increasing their use of pipelines and ports outside the Strait of Hormuz. Saudi Arabia can redirect crude through its East-West pipeline to the Red Sea, while the UAE can export some oil through Fujairah on the Gulf of Oman.

However, estimated alternative capacity of 3.5 million to 5.5 million barrels per day remains far below the approximately 20 million barrels that normally move through Hormuz. These routes can soften the disruption but cannot fully replace the waterway.

Iraq has also approved a three-month mechanism allowing crude exports through multiple outlets and specialised local and international companies from September 1. Meanwhile, two major Chinese shipping companies have stopped sending tankers through Hormuz and Bab el-Mandeb, choosing instead to collect cargoes outside the Gulf.

The EIA estimated that Hormuz oil flows averaged only 4.9 million barrels per day during the second quarter, down from 21.6 million in the final quarter of 2025. It also estimated that production shut-ins reached 5.5 million barrels per day in July.

What Could Move Oil Prices Next?

Immediate attention is likely to remain on verified tanker movements, further attacks and any change in the diplomatic positions of Washington and Tehran. A sustained increase in safe commercial transit could reduce the supply premium, while additional vessel or infrastructure attacks could keep WTI and Brent supported.

US inventory data provide another near-term catalyst. Preliminary industry figures indicated that crude and distillate inventories fell last week while gasoline stocks increased. The market expects official data to show a crude draw of approximately 600,000 barrels for the week ending August 14.

For price action, the psychologically important $86 level is the next nearby test for WTI, while Brent is approaching $92. Whether oil can remain above these levels will depend primarily on physical supply conditions rather than diplomatic headlines alone.
