Oil Falls 5% on Iran Deal Hopes as Hormuz Relief Could Take Months

On Sunday and Monday, when markets were closed for Memorial Day, Brent oil fell more than 5% to $95–$98 a barrel. This was because of renewed hopes for a deal between the U.S. and Iran that would conditionally reopen the Strait of Hormuz.

When WTI fell to about $91, it was the lowest it had been in over a month. S&P 500 futures soared to all-time highs near 7,559 points, while gold jumped 1% to $4,550 and silver gained 2.5% above $77. This shows how the market is pricing in both global de-escalation and ongoing inflation uncertainty at the same time.

The immediate cause: On Saturday, Trump wrote on Truth Social that a deal had been "largely negotiated," which included terms for reopening Hormuz. On Sunday, he changed his mind. He said that talks were going in a "orderly and constructive manner," but he had told officials "not to rush into a deal." The usual going back and forth.

What's Actually on the Negotiating Table

The technical plan that got out to the media doesn't talk about a permanent peace; it talks about a short-term crisis freeze. The draft that is being talked about has:

A 60-day extension of the ceasefire, during which the Strait of Hormuz would be open to commercial tanker travel under certain conditions again. Iran would be able to sell its own crude oil for a short time. In exchange, Tehran has accepted "in principle" to get rid of its stockpiles of highly enriched uranium.

The exact date and a ban on further enrichment will be decided in negotiations that have not yet been scheduled. The draft also talks about ending the war between Israel and Hezbollah in Lebanon.

The framework is in danger before it's signed because of three basic issues.

The dispute over the frozen funds. Iran strongly demands that its funds be unfrozen right away. Reporters have been told directly by Trump's government that the current framework does not allow for that. The Tasnim news service in Iran is already saying that the whole draft might be thrown out because of this problem.

Key limits are missing. The framework doesn't directly stop Iran's nuclear program or put a stop to enrichment for good, which were Trump's original two stated goals. Roger Wicker, the chairman of the Senate Armed Services Committee, called the new truce a "disaster" that wastes all military progress made in the past. At the same time, Trump says that Iran will "never have a nuclear weapon."

Pressure from Israel. Prime Minister Netanyahu reminded Trump in person that any final deal must completely get rid of Iran's nuclear threat, which is something that the present plan doesn't do.

In public, Marco Rubio, Secretary of State, says he is "very confident" that a deal can be made. The market's price changes happen in the space between his confidence and the problems that haven't been fixed.

The Physical Oil Reality That Markets Are Ignoring

The gap between the reaction of the futures market and the actual supply chain is the most significant analytical point in Monday's price action.

In the words of June Goh, senior oil market analyst at Sparta, "Fundamentally, there is no change to the underlying picture, where 10–11 million barrels per day of crude oil continue to be shut-in for every day the Strait of Hormuz remains shut." Markets are "expecting a gush of 100 million barrels of crude oil from the stranded ships to flow out once the deal is in place"; nevertheless, according to Sparta, it will take three to six months to return everything to normal, including refineries and output.

The most precise estimate comes from the CEO of Adnoc: even if hostilities ceased right once, it would take at least four months to return volumes to 80% of pre-war levels. At the latest, the first or second half of 2027 will see the reinstatement of full pre-war transportation capacity. Over one billion barrels of crude have been affected thus far by the fighting. Production at OPEC has dropped to levels not seen since 1990. About 20% of the world's gasoline and oil supplies as well as 20% of its LNG transportation were impacted by the Hormuz closure.

Yanbu and Fujairah are two alternate routes that Saudi Arabia and the United Arab Emirates have used to optimise pipeline capacity, however they are unable to fully offset the Hormuz volume deficit. The actual infrastructure reconstruction process operates on a multi-month timeframe that futures markets are unable to compress, even with a written agreement.

Even with maximum deal optimism, the short-term floor for Brent is expected to be about $85 per barrel; a full supply return scenario suggests a medium-term equilibrium of $75–$80, although that scenario is assessed in weeks rather than days.

According to the Sunday Truth Social post, the Trump blockade of Iranian ports is still in "full force and effect until an agreement is reached, certified, and signed." Since late February, the Hormuz waterway has been essentially blockaded; the disruption is already in its fourth month.

The market's price drop of 5% for oil is the deal probability, not the deal fact. There are important unresolved issues in the negotiating framework for both sides, including frozen assets on the Iranian side and the missile program and enrichment moratorium on the American side. These issues have stopped past diplomatic windows. This is the closest that U.S. and Iranian leaders have ever been, but "closer" does not mean "done."

Even if a deal is signed, it won't help with actual supplies until after a 3–6 month logistics rebuild. Things won't be back to normal until 2027. $95–$97 Brent shows how likely a deal is right now. When talks break down, Brent goes back to around $105–$110. When a deal is made, prices go down at first, but they will probably stay between $85 and $90 until the timeline for rebuilding supplies is priced into the forward curve.
