Oil tumbles as Trump cancels attack on Iran to reach nuclear deal

Market Reaction and Geopolitical Developments

By Florence Tan

Oil Price Movements

SINGAPORE, Aug 3 (Reuters) - Oil prices tumbled more than $4 a barrel on Monday after U.S. President Donald Trump held off on a fresh attack on Iran, seeking to reach a quick deal that would halt Tehran's nuclear ambitions and reopen the Strait of Hormuz.

Brent crude futures slid $4.49, or 5.11%, to $83.44 by 0408 GMT while U.S. West Texas Intermediate crude was at $79.77 a barrel, down $4.90, or 5.79%.

Recent Price Surge

Both contracts jumped more than 20% last month after fighting between the U.S. and Iran resumed and as attacks on several tankers around Oman heightened security concerns, deterring shippers from entering the Gulf to load oil.

Diplomatic Efforts and Regional Stability

De-escalation Signals

In a sign of de-escalation, Trump said late on Saturday on his Truth Social platform that Iran and other Middle Eastern countries had asked for time to complete a deal that would lead to "the Immediate, Complete and Total" reopening of the vital strait and "an end to Iran's nuclear threat".

Analyst Perspective

"The bigger focus is whether this week turns into a rinse and repeat of last week — with hopes of a deal collapsing as Iran digs in its heels and continues to leverage its control over the Strait, potentially through an attack on a U.S. base or a tanker transiting the waterway," IG market analyst Tony Sycamore said.

Shipping and Security Updates

Two tankers laden with Saudi oil crossed the Bab el-Mandeb Strait out of the Red Sea over the weekend while traffic in the Strait of Hormuz slowed following reports of vessel attacks, shipping data showed on Monday.

The United Kingdom Maritime Trade Operations has reported three more tanker attacks since Saturday.

OPEC+ Production and Market Impact

Production Quota Increase

On Sunday, OPEC+ approved an oil production quota increase of around 188,000 barrels per day from September, the producer group said, in a move that completes the unwinding of a layer of voluntary output cuts.

Export Disruptions and Market Effect

Due to export disruptions from the Gulf, Russia and Kazakhstan caused by the Iran and Ukraine wars, successive monthly OPEC+ hikes over most of this year have remained largely on paper with little impact on the market.

Key Takeaways

  • Trump paused planned strikes on Iran to pursue rapid negotiations, reducing geopolitical risk and sending oil prices down sharply.
  • Brent crude fell about 4.6% to $83.85 and US WTI dropped about 4.7% to $80.66, reversing previous gains from heightened Gulf tensions.
  • OPEC+ approved a modest production quota increase (~188,000 bpd from September), completing rollback of voluntary cuts amid persistent export disruptions.
