A sudden change in the language coming from Washington caused crude oil prices to reverse sharply on 3 August. US President Donald Trump said a planned strike against Iran had been called off to provide room for negotiations intended to reduce hostilities, address Iran’s nuclear programme and restore commercial navigation through the Strait of Hormuz.
The diplomatic picture, however, remains contradictory. Iran’s Foreign Ministry said there were no current direct negotiations with the United States. Tehran confirmed that it was discussing a temporary maritime arrangement with Oman, but maintained that an Oman agreement alone could not fully reopen the strait while US military operations and pressure continued.
The Run
| Development | Earlier position | Latest one.. | It means.. |
| Planned US military action | Markets were pricing the risk of another major strike on Iran. | Trump said the attack had been cancelled or postponed to permit diplomacy. | Immediate escalation risk declined. |
| Direct negotiations | Trump indicated that talks with Iran were expected. | Iran said no direct US–Iran talks were currently taking place. | The diplomatic breakthrough remains unconfirmed. |
| Hormuz discussions | Shipping remained severely restricted and exposed to attacks. | Iran confirmed discussions with Oman over a temporary safe maritime corridor. | Limited shipping relief may be possible even without a complete political agreement. |
| Oil-market reaction | Brent and WTI had gained more than 20% during July amid renewed conflict. | Both benchmarks fell by more than $4 a barrel during Monday trading. | Part of the geopolitical risk premium was rapidly removed. |
| OPEC+ supply | Successive production increases had struggled to reach markets because of Gulf export disruption. | Seven OPEC+ members approved another combined quota increase of approximately 188,000 barrels per day for September. | More notional supply is available, but physical exports remain dependent on shipping security. |
Oil Prices on 3 August 2026
| Benchmark | Reported price | Daily movement | Market interpretation |
| Brent crude | Approximately $83.25–$83.56 a barrel | Down around 5% | Lower probability of an immediate US strike |
| West Texas Intermediate | Approximately $79.31–$80.00 a barrel | Down around 5.5%–6.3% | Reduced short-term supply panic |
| July direction | Both contracts gained more than 20% | Strong monthly rise | Renewed US–Iran fighting and tanker-security concerns |
| September OPEC+ adjustment | About 188,000 barrels per day | Planned quota increase | Additional downward pressure, provided the barrels can be exported |
Prices varied during the trading session. The ranges above reflect the different observation times used by major financial publications rather than a contradiction in the underlying direction.
Why Oil Fell Before the Strait Fully Reopened
Oil futures do not respond only to the physical quantity of oil moving on a particular day. They also price the probability of future disruption.
Trump’s decision reduced the immediate probability of a larger military confrontation. Traders therefore removed part of the premium that had accumulated during July. Nevertheless, Tehran’s rejection of the US account means the market has reacted to the possibility of diplomacy, not to a signed and implemented agreement.
The Strait of Hormuz also cannot return instantly to normal operations. Shipping companies must assess naval activity, mines, missile threats, tanker attacks and war-risk insurance. Gulf producers may also need time to restore production after shutting wells, filling domestic storage or diverting cargoes.
The US Energy Information Administration had estimated in June that Middle Eastern production shut-ins averaged about 11.3 million barrels per day in May because traffic through Hormuz remained extremely limited. Its forecast assumed that shipments would recover gradually during the third quarter, with pre-conflict trade patterns potentially not returning until early 2027.
The Three Different Hormuz Positions
| Participant | Public position | Unresolved issue |
| United States | A broad agreement can reopen Hormuz and address Iran’s nuclear capabilities. | Iran has not confirmed direct negotiations. |
| Iran | It is discussing maritime arrangements with Oman, not negotiating directly with Washington. | Tehran links reopening to an end to US military pressure. |
| Oman | Acting as the principal channel for a temporary shipping arrangement. | A corridor arrangement may not resolve the wider US–Iran conflict. |
The distinction matters. A temporary shipping corridor, a comprehensive reopening of the strait and a wider US–Iran political settlement are three separate outcomes. Reports suggesting that Hormuz has already returned to normal would therefore be premature.
What to Watch Next
| Indicator | Positive signal | Risk signal |
| US–Iran contact | Both governments confirm the same meeting or negotiating framework. | Continued contradictory statements. |
| Tanker traffic | Sustained rise in commercial transits without attacks. | More explosions, seizures or route diversions. |
| Brent crude | Price stabilises near or below the low-$80 range. | Renewed movement towards $90 or above. |
| Oman talks | A published and enforceable safe-passage arrangement. | Negotiations remain informal or are rejected by other parties. |
| OPEC+ output | Higher quotas translate into measurable exports. | Production rises only on paper because tankers cannot load or transit safely. |
