Hormuz Traffic Collapses as US-Iran Ceasefire Unravels: Oil Holds Near $78, Energy Stocks Diverge

The three-week-old US-Iran ceasefire is fracturing in real time, and the market tell is not in the headline index moves — it is in the Strait of Hormuz, where ship traffic has collapsed to its lowest level since the interim deal was signed in mid-June. The energy market is pricing a supply disruption that equity investors have not fully reconciled with their risk models. The divergence between oil-producing and oil-consuming equities is the signal worth tracking.

What happened: 48 hours from ceasefire to crossfire

On July 8, President Donald Trump declared the June 17 memorandum of understanding with Iran “over,” following Iranian attacks on at least three commercial vessels in the Strait of Hormuz{{cite:36d70a6dd8a0}}. US Central Command launched strikes against more than 80 Iranian military sites near the strait — air defenses, radar installations, and IRGC naval assets{{cite:36d70a6dd8a0}}. The Treasury Department simultaneously revoked the 60-day sanctions waiver that had permitted Iranian oil sales, moving the cutoff deadline to July 17 and effectively freezing millions of barrels of Iranian crude already loaded in the Gulf{{cite:f7ec649f66a3}}.

The strikes continued into July 9, with US forces hitting 90 targets in a second wave{{cite:36d70a6dd8a0}}. Iran retaliated by firing missiles and drones at Bahrain, Kuwait, and Qatar — Gulf states that had hosted US military infrastructure{{cite:36d70a6dd8a0}}. Trump warned the attacks “could get much worse” and raised the prospect of seizing Iran’s Kharg Island export hub, the country’s main oil-loading terminal{{cite:f30c7ffa1985}}.

Yet by Thursday morning, Trump also said he expected the flare-up to “end quickly” and claimed Tehran had called wanting “to make a deal so badly”{{cite:f30c7ffa1985}}. This oscillation — maximalist threats followed by deal-making signals within hours — is the core uncertainty the market is now pricing.

The shipping tell: Hormuz grinds to a halt

The most concrete market-relevant development is not the rhetoric but the physical traffic data. Only 14 commodity carriers transited the Strait of Hormuz in both directions on Wednesday, July 8 — the lowest count since the interim peace deal was signed{{cite:5470d2fc38b8}}. By Thursday, traffic had come to a near-standstill. Among larger vessels, only a US-sanctioned supertanker and an Iranian-flagged container ship were observed in the strait{{cite:5470d2fc38b8}}.

This is a stark reversal from the recovery that followed the June 17 MoU. In the three weeks since the deal, average daily transits of commodity vessels through Hormuz ran at 34, with a peak of 59 on June 24{{cite:5470d2fc38b8}}. That figure compared with wartime daily counts of fewer than 20 on most days. The US-supported Omani corridor fell quiet on Thursday, with visible movements concentrated along an Iran-approved northern route{{cite:5470d2fc38b8}}.

LNG tanker traffic through the strait was at a complete standstill, though two empty vessels were heading toward the eastern entrance{{cite:5470d2fc38b8}}. Ship-tracking data also showed signs of electronic interference returning, with vessels southeast of Limah in Oman appearing to travel at implausible speeds of 30+ knots — a signature of defense-system activation affecting transponder signals{{cite:5470d2fc38b8}}.

At least four oil and gas tankers turned back from Hormuz after the vessel attacks{{cite:b87e355fa836}}. The International Maritime Organization urged the industry to avoid transiting the waterway if crew safety cannot be guaranteed{{cite:768c43bdc0df}}. Some war insurers are advising shipowners to pause Hormuz voyages entirely{{cite:5470d2fc38b8}}.

Oil: Brent holds near $78 after 5% surge

Brent crude rose more than 5% on Wednesday, July 8 — its strongest daily gain since May — and held near $78.30 per barrel on Thursday morning{{cite:a5911424a969}}. The contract briefly topped $80 in early Asian trade before paring gains{{cite:f30c7ffa1985}}. West Texas Intermediate traded near $74, bringing oil’s two-session gain to more than 6%{{cite:466db3abe441}}.

The Brent September contract had reached $76.48 by early Wednesday — the highest since June 23 — before the second wave of strikes pushed it further{{cite:f7ec649f66a3}}. FT markets data showed Brent at $78.60 as of midday Thursday{{cite:a5911424a969}}.

Supply concerns are amplified by tightening US fuel inventories. Commercial crude stockpiles rose by nearly 3 million barrels last week, but a 6.2 million-barrel draw from the Strategic Petroleum Reserve meant overall US oil inventories fell by more than 3 million barrels{{cite:466db3abe441}}. Distillate inventories — including diesel — declined by 5 million barrels, while gasoline stockpiles fell to their lowest seasonal level since 2012{{cite:466db3abe441}}.

Saul Kavonic, head of energy research at MST Financial, told Al Jazeera that Iran “fully intends to cement its control over the Strait of Hormuz in the coming weeks,” which could keep passage below 50% of pre-war levels for many months, with periodic flare-ups{{cite:f7ec649f66a3}}.

Equity markets: energy up, transport down, indices split

The equity response on Wednesday, July 8, was a classic risk-off rotation split along the oil price axis. The S&P 500 fell as much as 1.1% intraday before paring losses{{cite:b7522e7a57c0}}. The Dow dropped over 500 points{{cite:b7522e7a57c0}}. Oil stocks rose while travel stocks fell as the Wall Street session began{{cite:b7522e7a57c0}}.

Among energy names, ConocoPhillips (COP) gained 2.1% to close at $110.72, and Halliburton (HAL) rose 3.5% to $34.97 on July 8{{cite:01a25622a104}}. Chevron (CVX) added 1.1% to $175.91{{cite:01a25622a104}}. ExxonMobil (XOM) was the outlier among majors, slipping 0.5% to $140.95{{cite:01a25622a104}}. The oil ETF USO rose 3.0% to $112.21, while the Brent-tracking BNO fund gained 3.9% to $43.57{{cite:01a25622a104}}.

Airlines took the heaviest hit on the consumption side. American Airlines sank 5%, United fell 4%, and Delta and JetBlue each slipped 3% as crude oil jumped{{cite:b7522e7a57c0}}. Logistics companies also felt the pressure: UPS declined 1.8% to $109.94 and FedEx dropped 1.0% to $309.76{{cite:01a25622a104}}, reflecting both fuel-cost exposure and the potential for Hormuz disruption to cargo routes.

In pre-market on July 9, COP gave back 1.5% to $109.06 as oil stabilized, while HAL edged 0.3% higher to $35.08{{cite:01a25622a104}}. FedEx was up 1.0% in pre-market at $313.00{{cite:01a25622a104}}. These early reads suggest the market is now distinguishing between a temporary flare-up and a sustained disruption — but that distinction hinges entirely on whether the Hormuz traffic collapse persists.

The sanctions waiver revocation: a second channel of supply risk

Beyond the kinetic escalation, the Treasury’s revocation of the Iranian oil sanctions waiver is a separate supply shock that the market is still digesting. The waiver, issued in June, had authorized Iranian oil sales through August 21 as part of the negotiations framework. The new order moves the cutoff to July 17 and prohibits any new transactions, including purchases or loading, effective immediately{{cite:f7ec649f66a3}}.

Millions of barrels of Iranian crude that had moved out of the Gulf under the sanctions easing are now in legal limbo{{cite:466db3abe441}}. This creates a binary: either the waiver is restored as part of a renewed diplomatic track, removing that supply from the market for a defined period, or it remains revoked, tightening global supply by the volume Iran had been exporting under the waiver.

Iranian Deputy Foreign Minister Kazem Gharibabadi called the revocation a “blatant violation” of the MoU and said Tehran would take “decisive actions” to safeguard its interests{{cite:f7ec649f66a3}}. That language stops short of threatening a full Hormuz closure but signals that Iran views the sanctions move as a breach of the diplomatic framework, not merely a military escalation.

What to watch next

Hormuz transit counts. The daily Kpler commodity-vessel count is the most direct leading indicator. Wednesday’s 14 transits need to be compared against Thursday and Friday data. If traffic remains below 20 for consecutive days, the market will start pricing a sustained disruption rather than a short flare-up. The pre-war baseline was 34 daily under the MoU; anything persistently below 20 signals a return to wartime conditions{{cite:5470d2fc38b8}}.

The July 17 sanctions deadline. If the Treasury waiver revocation holds, Iranian oil exports effectively stop on that date. Watch for any signaling from the Treasury or State Department about whether the deadline is a negotiating lever or a hard cutoff. A restoration of the waiver would be the single fastest de-escalation signal.

Iran’s retaliation scope. Tehran’s strikes on Bahrain, Kuwait, and Qatar mark an expansion of the conflict’s geographic footprint{{cite:36d70a6dd8a0}}. If Gulf state infrastructure — particularly LNG facilities in Qatar — is damaged, the energy market response would be disproportionate to the oil-specific moves seen so far. Qatar is the world’s largest LNG exporter, and LNG traffic through Hormuz is already at a standstill{{cite:5470d2fc38b8}}.

Trump’s deal-making signals. The president’s claim that Iran “called” to make a deal, combined with his statement that the flare-up would “end quickly,” introduces a de-escalation path that could reverse the oil surge as fast as it arrived{{cite:f30c7ffa1985}}. The pattern — threats followed by deal-making optimism — has been a recurring feature of this conflict. Neil Wilson at Saxo Markets noted that Trump’s proclivity for throwing around threats, combined with both sides’ need for a return to pre-war normality, suggests a total negotiation breakdown is not the base case — but the risk has clearly increased{{cite:f30c7ffa1985}}.

SPR and US inventory data. The 6.2 million-barrel SPR draw last week, combined with gasoline at its lowest seasonal level since 2012, means the US buffer is thinning at a moment when import disruption is a live risk{{cite:466db3abe441}}. Subsequent weekly inventory reports will show whether the emergency drawdown is accelerating in response to the Hormuz slowdown.

Defense sector flows. The escalation has put aerospace and defense stocks back in focus{{cite:b7522e7a57c0}}. Sustained conflict would support defense outperformance, but a rapid diplomatic resolution would remove that tailwind. The defense trade is now tightly correlated with the diplomatic calendar, not just the military one.
