Brent crude fell 5% to US$83.32 per barrel, while U.S. West Texas Intermediate (WTI) dropped 5.5% to US$80.00 per barrel on Monday, August 3, 2026, after President Donald Trump delayed a planned military strike on Iran and signalled renewed negotiations over the Strait of Hormuz. The decline followed Brent's nearly 25% rally in July, its strongest monthly gain since March, as traders unwound part of the geopolitical risk premium built into oil prices amid improving expectations for Middle East diplomacy.

Why Oil Prices Fell So Sharply
Trump said negotiations with Iran would begin on Monday after he cancelled a planned military strike, saying diplomatic efforts could help reopen the Strait of Hormuz. Trump said Iran, along with regional allies including Saudi Arabia, the UAE and Qatar, had asked him to delay the planned strike. Iranian officials later denied making such a request, highlighting the uncertainty surrounding the negotiations. Iran's Fars News Agency, affiliated with the Islamic Revolutionary Guard Corps, publicly dismissed the proposal as a "wish list."
The Strait of Hormuz sits at the center of the standoff. The waterway normally carries around one-fifth of the world's seaborne crude oil, petroleum products, and LNG exports, making any sustained disruption a major threat to global energy markets and any credible progress toward reopening it a major driver of price relief.
1- Gulf Producers Diversify Export Routes
Even as diplomacy progresses, Gulf producers are reducing their reliance on the Strait of Hormuz. Turkey and Iraq agreed to extend their oil pipeline agreement by one year, enabling exports of up to 750,000 barrels per day through an alternative overland route, a hedge against continued chokepoint risk.
2- Shipping Risks Continue Despite Diplomacy
The de-escalation has not eliminated risk on the water. Shipping risks also persisted despite the diplomatic breakthrough. Reports said 35 ships had been forced to turn back amid the ongoing US naval blockade of Iranian ports, highlighting that disruptions to regional shipping have not yet been fully resolved. The blockade targets shipping to and from Iranian ports specifically rather than imposing a blanket closure of the Strait of Hormuz, an important distinction for assessing how much physical supply is actually at risk.
OPEC+ Output Increase Adds to Selling Pressure
OPEC+ approved a further 188,000 bpd production increase for September, continuing the phased unwind of 2023 voluntary cuts:
This is the completion of the planned restoration of prior output cuts, positioning OPEC+ to raise supply further once Middle East tensions ease. Markets read easing geopolitical risk alongside higher OPEC+ supply as a double bearish signal, compounding Monday's sell-off.
How Oil ETFs Reacted to the Latest Sell-Off
The recent pullback in crude oil prices weighed on oil-focused ETFs, with commodity-tracking funds recording the sharpest declines. USO and BNO, which track WTI and Brent crude futures respectively, fell around 19% over the past month and more than 20% over the past three months, despite remaining up 48.52% and 42.84% year-to-date.
Energy equity ETFs proved relatively more resilient. OIH and IEZ, which focus on oilfield services, declined around 10–11% over the past month, while exploration and production funds XOP and IEO posted smaller one-month losses of 5.50% and 3.26%, respectively. Despite the recent correction, all six ETFs remain in positive territory for 2026, highlighting the sector's strong gains earlier in the year.
Why GCC Crude Held Up Better Than Global Benchmarks
Not all crude benchmarks moved in the same direction. While Brent and WTI fell sharply, Murban crude, the Abu Dhabi/ADNOC benchmark, rose 1.26% to US$85.49 per barrel. Unlike Brent futures, Murban reflects pricing in the physical Gulf crude market, which remained supported by regional supply concerns and shipping disruptions despite easing geopolitical tensions. Natural gas also edged 0.66% higher, suggesting that parts of the broader energy complex continued to reflect supply risks even as global crude prices retreated.
The mixed performance highlights an important distinction for GCC markets. Although lower global oil prices could weigh on investor sentiment if sustained, the resilience of Murban indicates that regional energy fundamentals remain more stable than the sharp moves seen in international futures markets. As a result, Gulf equity markets may experience more measured reactions unless weaker oil prices begin to affect corporate earnings, government revenues, and fiscal spending across the region.
Conclusion
While Monday's sharp decline suggests markets are pricing in a lower probability of an immediate supply shock, oil remains highly sensitive to developments around the Strait of Hormuz. Any setback in negotiations or renewed disruption to Gulf shipping could quickly restore the geopolitical premium. For GCC investors, monitoring both diplomatic progress and OPEC+ supply decisions will remain critical over the coming weeks.
