Washington and Tehran Stay Cool, but Hormuz Keeps Markets on Edge

Washington and Tehran are signaling restraint, but the market still sees risk

This is not yet a clean de-escalation story. It is a market caught between relief-seeking and reality-checking. The headline calm looks safer than the underlying signal: earlier this month, just two vessels transited the Strait of Hormuz, versus roughly 130 to 140 ships in normal times before the war began. That gap is large enough that markets cannot treat recent calm as a full reset.

Diplomatic headlines are moving prices faster than verified flows

Trump's remark about an "all-day negotiation" gave markets the kind of simple de-escalation narrative investors often reach for under stress on Tuesday. Reuters says that remark and the broader de-escalation read helped drive a 5% drop in oil prices as traders leaned into the possibility of faster normalization. But Iran then said peace talks were not under way, which helps explain why the rally has felt fragile rather than decisive.

That context matters because the stakes for next week's inflation data have risen. If energy prices surge again, investors will have less room to read this week's calm as a clean reset.

Oil is showing how fast war premiums can unwind - and why the unwind is still incomplete

Oil remains the clearest barometer here because it compresses geopolitical risk, shipping constraints, insurance and delay costs, and near-term demand concerns into one price. When reports emerged that talks between Iran and Oman are making progress, traders had a simpler story than the one they had the day before. That is how war premiums start to melt. Prices fell not because the choke point had returned to normal, but because investors discounted a better outcome.

When Trump described an "all-day negotiation" on Tuesday, the market responded to that relief cue aggressively. The follow-through has been less decisive because the diplomatic signal has not yet been matched by verified traffic through the strait.

The physical picture is still constrained

The fundamental check still matters. Earlier this month, just two vessels transited the Strait of Hormuz, far below the roughly 130 to 140 ships that typically move through before the war. That is why the oil move should be read as a partial unwinding of fear, not proof that flows have normalized.

What supports the more measured view is that some cargo is still getting through. U.S. imports of Middle Eastern crude are set for about 600,000 barrels per day in August, the highest since the Iran war began. That does not prove the strait is open, but it does suggest shipments are finding routes instead of remaining fully trapped by the disruption.

Aramco provides another data point. The company posted a 44% increase in net profit in the quarter to end-June despite disruptions in the Strait of Hormuz. The takeaway is not that the crisis is over; it is that earnings have remained resilient even with the chokepoint impaired.

What would confirm or break the rally

Over the next few sessions, the market is likely to hinge on three things:

• Diplomacy becomes verifiable. Markets need more than whispers; they need sustained evidence that talks are producing workable outcomes.
• Hormuz traffic recovers. Oil will keep reacting to headlines until shipping data starts to show a durable improvement.
• Energy prices stop reasserting the risk premium. If crude climbs again, the relief trade is unlikely to hold through next week's inflation data.
