Markets Price a Hormuz Breakthrough; the Risk Floor Hasn't Moved

Markets Are Betting the Deal Is Done

The S&P 500 surged 1.8 percent on Tuesday to top 7,700 for the first time, and the Dow Jones Industrial Average set a record for a second straight day at 54,085.88, as US officials publicly signaled that an agreement to reopen the Strait of Hormuz could come within hours.^[1] Treasury Secretary Scott Bessent told CNBC on Tuesday morning that “there is a chance we may have a deal today or tomorrow to open the strait.”^[2] Secretary of State Marco Rubio added that progress had been made but “not finality yet,” and that he hoped a deal would “happen very shortly.”^[1]

Oil prices collapsed on the prospect. Brent crude, the international benchmark, slid 5.3 percent to close at $79.36 per barrel on Tuesday, while West Texas Intermediate lost 5.7 percent to settle at $75.77 — both at three-week lows.^[2] By Wednesday, Brent was little changed at $79.43 and WTI traded at $75.27, as the market waited for confirmation.^[3]

The mechanics of the proposed deal, as reported by Axios, involve an interim arrangement: inbound ships would transit Iran’s territorial waters, while outbound vessels would sail through Oman’s waters in coordination with Tehran.^[3] Iran’s foreign ministry described talks with Oman as “positive,” while Qatar — a key mediator — said it was continuing efforts toward a diplomatic resolution.^[2]

A Deal That Collapsed Once Before

What the market is pricing as near-certain has failed before. The US and Iran signed a memorandum of understanding on June 17 to open the strait, but the deal “quickly collapsed” as fighting erupted over the route ships would take through the waterway.^[3] Tehran attacked vessels sailing along Oman’s coast under US military protection, attempting to force ships into its territorial waters; Washington retaliated with more than a dozen waves of airstrikes and reimposed its naval blockade on Iran.^[3]

Before the US-Israel war on Iran began in late February, the Strait of Hormuz handled about one-fifth of global daily oil and LNG supplies.^[2] Maritime traffic has since been severely constrained: just nine vessels transited the strait on Sunday, compared with roughly 130 daily crossings before the war.^[1] LNG exports through Hormuz have declined by 95 percent, according to the UN.^[4] Saudi Aramco estimates the conflict has removed more than 2.6 billion barrels of oil from the global market.^[4]

The Risk Floor: Three Escalation Vectors Still Active

Houthis Strike a Saudi Tanker in the Red Sea

Even as Hormuz talks advanced, Iran’s Houthi allies in Yemen claimed they struck a Saudi tanker with a missile near the coast of Yanbu — a major port for Riyadh’s crude exports — in the Red Sea on Wednesday.^[3] Oil prices briefly moved higher on the report before settling back.^[3] The Houthis have blockaded Saudi Arabia’s Red Sea ports since July 20, closing a route that had become a critical alternative after Iran choked off the strait.^[2] On Tuesday, a projectile sank an Indian-flagged vessel near Yemeni waters.^[2] Analysts assess the threat to oil tankers in the region as the worst since the Iran war started.^[4]

China Rolls Out Countermeasures Ahead of Xi-Trump Summit

On the same day the market celebrated Hormuz progress, Beijing announced a swath of retaliatory measures against the United States.^[5] China’s Ministry of Commerce sanctioned multiple American entities — including a biotech firm and a resource analytics company — tightened export controls on drones and related components to the US, added six firms to its countermeasures list in response to a US ban on 43 Chinese companies over alleged Uyghur forced-labor ties, and launched a national security investigation into imported office equipment with foreign system software.^[5] A seventh company’s listing was tied to the FCC’s ban last month on imports of new humanoid and quadruped robots from China.^[5]

The countermeasures come weeks ahead of an expected Xi-Trump summit in the US next month, and a Chinese commerce ministry spokesperson warned that “if the United States insists on introducing new restrictive measures against China, China will take further countermeasures.”^[5] The administration recently sanctioned Chinese shipping operators alleged to be handling Iranian fuel, added Chinese universities to a Pentagon blacklist, and imposed 10–12.5 percent tariffs on China over forced-labor concerns.^[5]

EU Adopts Its Largest Sanctions Package in Four Years

On July 23, the Council of the European Union adopted its 21st sanctions package against Russia — the largest batch of listings in four years, covering 48 individuals and 170 entities.^[6] The package expands transaction bans to 33 additional Russian financial institutions and one Kyrgyz bank, targets five oil traders involved in circumventing the Russian crude prohibition, adds 51 entities to the stricter export-control list (including third-country entities in China, India, Kazakhstan, Kyrgyzstan, Türkiye, and the UAE), and introduces new crypto-asset measures — including a prohibition, effective August 25, on Russian nationals owning or controlling crypto-asset businesses in EU member states.^[6]

The 21st package also bans imports of copper, nickel, lead, precious-metal ores, unwrought zinc, and car parts worth more than €60 million, and adds export restrictions on nickel powders, beryllium powders, and UAV components including jamming and interception systems.^[6] The sanctions pressure on Russia is tightening, not loosening, even as oil prices fall.

The Oil-Major Paradox and the Consumer Squeeze

The war premium has generated record profits for integrated oil majors. BP, Shell, Chevron, and Exxon Mobil have all reported bumper earnings from wartime refining margins,^[2] even as Brent has swung between $120-plus during escalations and sub-$80 on de-escalation hopes.^[2] At the pump, US gasoline averages above $4 per gallon, and diesel is near $5.40.^[2] In the UK, average petrol prices have returned to levels seen at the start of the conflict, at £1.60 per litre.^[2]

Meanwhile, the US has used nearly all of its global stockpile of long-range precision missiles, according to two sources with direct knowledge cited by CBS News.^[2] The munitions constraint — largely unreported by markets — is a quiet indicator of how much sustained capability remains for a prolonged campaign.

What the Market Is Pricing vs. What Could Break

The market’s read is internally consistent: a Hormuz deal this week drops the war premium from oil, eases inflation pressure, and extends the equity rally. The S&P 500 is up 12.8 percent year-to-date, comfortably above its historical average of about 10.5 percent.^[1] But that thesis rests on a deal that has collapsed once already, faces active sabotage from Iran’s own proxies, and coincides with simultaneous escalation on the China and Russia sanctions fronts.

Three indicators would confirm the de-escalation narrative: (1) Hormuz transit numbers returning toward the pre-war baseline of ~130 daily crossings; (2) Brent holding below $80 for a sustained period rather than snapping back on the next incident; and (3) a Xi-Trump summit that produces a tariff truce rather than another round of tit-for-tat measures. None of those has happened yet.

Three indicators would break it: (1) a second collapse of a signed Hormuz arrangement, as occurred in June; (2) a Houthi or Iranian attack on a major oil production facility rather than a single tanker; or (3) China pairing its countermeasures with a rare-earth or drone-component export ban that directly constrains US defense supply chains.

What to Watch Next

• Hormuz transit data: MarineTraffic and Kpler daily transit counts. A move from single digits toward even 30–50 daily crossings would signal the deal is holding; stagnation below 20 would indicate implementation friction.
• Brent reaction to confirmation: A deal announcement that fails to push Brent decisively below $78 would indicate the market has already priced the outcome and sees residual risk.
• Red Sea shipping lane: The Houthi blockade of Saudi Red Sea ports is a separate vector. If the Yanbu strike is followed by more attacks, even a Hormuz deal may not fully release oil supply.
• Xi-Trump summit preparation: The next round of US-China trade talks and whether China’s countermeasures expand to critical minerals. A drone or rare-earth export ban would be a materially different escalation from sanctions on individual firms.
• EU sanctions implementation timeline: The August 25 effective date for the crypto-asset business ownership ban and the October 25 transition period for pre-existing import contracts are the next enforcement milestones.
• US munitions stockpile: Any public reporting on the replenishment rate of long-range precision missiles. A drawn-out Hormuz enforcement commitment becomes harder to sustain if the stockpile is depleted.
