Oil falls more than 5% as Brent drops below $100 on reports of U.S.-Iran progress

Markets pare premiums after weekend claims of a near-term memorandum of understanding, even as Strait of Hormuz flows stay well below pre-war levels

By Priya Menon

Oil prices declined sharply in early Asian trading on Monday after reports that a memorandum of understanding between the United States and Iran was largely negotiated. Brent futures slipped beneath the $100-per-barrel mark while U.S. crude also posted a steep drop. Despite signs of diplomatic movement, constrained tanker traffic through the Strait of Hormuz continues to limit global supply flexibility.

Oil falls more than 5% as Brent drops below $100 on reports of U.S.-Iran progress

Key Points

  • Brent July futures dropped over 5% to $98.12 a barrel; WTI futures slid 5.2% to $91.31 a barrel, reflecting sharp market repricing in early Asian trade.
  • U.S. statements described a memorandum of understanding with Iran as "largely negotiated" and aimed at reopening the Strait of Hormuz, while Iranian state media disputed that a deal was near final.
  • Flows through the Strait of Hormuz remain a fraction of pre-war levels, keeping global oil markets constrained and providing a price floor despite recent declines.

Market moves

Oil prices tumbled in early Asian trade on Monday, with Brent dipping below the $100-per-barrel threshold amid reports of progress in talks between the United States and Iran. July Brent futures fell by more than 5% to $98.12 a barrel, marking their weakest level in nearly three weeks. U.S. West Texas Intermediate futures declined 5.2% to $91.31 a barrel.

Diplomatic developments cited

Over the weekend, U.S. President Donald Trump said a memorandum of understanding on a peace deal with Iran was "largely negotiated," describing the agreement as aimed at reopening the Strait of Hormuz. Several reports indicated that both parties and Pakistani mediators were signaling progress toward a deal.

However, Iranian state media issued statements that contradicted Mr. Trumps assertion that a deal was nearly final. Later comments from the U.S. President said there was no rush to complete an agreement and that a naval blockade against Iran would remain in place until a deal was reached.

Persistent points of contention

Washington and Tehran remain in disagreement on a number of core issues, with Iran's nuclear activities singled out as a central sticking point. According to the available reporting, Tehran has largely rejected U.S. demands that it surrender its stocks of enriched uranium.

Price context and supply constraints

Crude prices were extending losses carried over from last week after Mr. Trump signaled some progress toward negotiations. Market participants pared risk premia on the prospect of reduced geopolitical tension, but physical oil flows through the Strait of Hormuz continue to run at only a fraction of pre-war levels. That reduced throughput is keeping global oil markets relatively tight and is cited as a factor providing a floor beneath prices despite recent declines.


Key points

  • Brent July futures fell over 5% to $98.12 a barrel; WTI futures slid 5.2% to $91.31 a barrel - significant moves for energy markets.
  • U.S. statements said a memorandum of understanding with Iran was "largely negotiated," aimed at reopening the Strait of Hormuz, though Iranian state media disputed that a deal was near finalization - developments that directly affect oil risk premia and shipping.
  • Reduced flows through the Strait of Hormuz remain a constraint on global supply, supporting a baseline for prices even as risk premiums retreat.

Risks and uncertainties

  • Contradictory public statements - Iranian state media contradicted U.S. comments about how close a deal was, leaving the outcome uncertain. This uncertainty affects energy markets and maritime operations.
  • Core disagreements remain - Washington and Tehran remain at odds over Iran's nuclear activities and demands regarding enriched uranium, which could complicate or stall negotiations and influence future price direction.
  • Ongoing constrained shipping - Flows through the Strait of Hormuz are still at a fraction of pre-war levels; any further disruption or slow recovery of shipping volumes would sustain supply-side pressure on global oil markets.

These developments leave markets sensitive to further diplomatic signals and operational data on shipping through the Strait of Hormuz. For now, the combination of reported negotiation progress and continued physical constraints has driven a sharp near-term repricing in crude futures.

Risks

  • Contradictory public accounts of negotiation progress increase uncertainty, which could lead to further price volatility in oil and affect shipping-related sectors.
  • Key disagreements persist between Washington and Tehran on Iran's nuclear activities and demands over enriched uranium, posing the risk that talks stall or collapse.
  • Continued reduced throughput through the Strait of Hormuz maintains supply-side constraints; any further disruptions would continue to influence global energy markets.
