Oil prices fell sharply in early Asian trading on Monday after U.S. President Donald Trump called off another round of military strikes against Iran, fueling speculation that a diplomatic pathway to reopening the Strait of Hormuz and avoiding a wider regional conflict may be within reach.

At the time of writing, West Texas Intermediate (WTI) futures were trading at $79.77 per barrel, down 5.88%, while Brent crude futures had fallen to $83.47, down 5.07%.

The sell-off follows an exceptionally volatile July, during which both benchmarks surged more than 20%. Renewed hostilities between the United States and Iran, combined with a Houthi blockade of Saudi ports, had heightened fears of extended supply disruptions through the Strait of Hormuz and the Red Sea.

On Saturday, the situation appeared poised to escalate further when President Trump warned that the United States was preparing to launch what he described as the "biggest attack since World War II" against Iran. He subsequently called off the planned strike, stating that regional leaders had persuaded him a deal was close.

As has occurred repeatedly since the conflict began, the prospect of de-escalation triggered a sharp drop in oil prices when markets opened on Monday. Whether this latest diplomatic overture will prove more durable than previous efforts remains to be seen.

On the maritime front, two Saudi oil tankers successfully transited the Bab el-Mandeb Strait over the weekend, indicating that Red Sea shipping traffic is still moving. However, the United Kingdom Maritime Trade Operations (UKMTO) agency reported three additional tanker attacks since Saturday, underscoring that maritime risks in the region remain elevated.

Additional downward pressure on prices came from OPEC+, which approved a production quota increase of approximately 188,000 barrels per day for September, completing the unwinding of one layer of its voluntary production cuts. The group has been gradually restoring output it had curtailed over the past two years to support prices, but actual supply increases have lagged behind quota adjustments as several members struggle to meet existing targets. Because actual output increases have remained constrained by regional disruptions, the immediate market impact has been limited.

Diplomatic activity is not limited to the United States. Iranian officials have indicated that negotiations with Oman over a new shipping arrangement through the Strait of Hormuz are in their final stages. Tehran has continued to insist that vessels will no longer be permitted to use the previous southern shipping lane off Oman's coast, signaling that even if the Strait reopens, shipping patterns could shift substantially.

If the negotiations hold and regional shipping returns to normal operations, a significant portion of the geopolitical risk premium that built up during July could continue to unwind in the coming weeks. However, absent a broader agreement, any renewed military escalation or disruption to Gulf exports would likely send crude prices sharply higher.
