Oil hits $100 as Strait of Hormuz stays closed despite ceasefire

Iran claims ceasefire terms already violated within 24 hours; LNG sector left scarred as Goldman Sachs resets oil price forecasts

Briefing

Crude prices have hit $100 a barrel after the largest single-day drop since 2020, as the US-Iran ceasefire showed immediate signs of collapse. The Strait of Hormuz remains blocked, keeping a physical constraint on supply that traders have not priced out. Iran's assertion that ceasefire terms were violated within 24 hours has stalled equity futures and halted an emerging-market recovery. Goldman Sachs has reset its oil price forecasts for the rest of 2026, and an industry executive warned that the LNG sector has been left scarred by the conflict.

Oil Hits $100 as Ceasefire Credibility Collapses

Crude prices climbed to $100 a barrel on Wednesday after posting their steepest single-session decline since 2020, as scepticism over the durability of the US-Iran ceasefire reasserted itself across energy markets.

The Strait of Hormuz, through which a significant share of global seaborne oil flows, remains physically blocked, according to Bloomberg. That supply constraint has given traders a tangible reason to fade the ceasefire-driven sell-off, regardless of diplomatic posturing. The S&P 500 has diverged from oil, however, with equity markets showing more resilience than crude prices as the Hormuz closure persists, Investor's Business Daily reported.

Iran's claim that the ceasefire had been violated within 24 hours of its announcement compounded the uncertainty. US equity futures wavered on the news, and an emerging-market rebound that had briefly taken hold stalled, Bloomberg reported.

The sequence of events has exposed the fragility of market moves driven by geopolitical announcements rather than verified changes on the ground. Reuters reported that traders placed a $950 million options bet on falling oil prices in the hours immediately before the ceasefire was announced, a position that will be under pressure as prices recover.

Goldman Sachs has reset its oil price forecasts for the remainder of 2026, TheStreet reported, reflecting the scale of the uncertainty introduced by the conflict and the unresolved status of the Strait. An industry executive told Reuters that while the ceasefire had eased some fears, the LNG sector had been left scarred by the episode, suggesting supply chain and contracting disruptions that will persist beyond any near-term diplomatic resolution.

Republican lawmakers have been cautious about claiming victory on energy prices despite the ceasefire, Politico noted, a signal that the political calculus in Washington remains unsettled. Retail gasoline prices are unlikely to fall to $3 a gallon in the near term even if crude were to decline further, owing to refining margins and distribution costs, according to CNN.

The Economist has argued that the broader conflict, which it has characterised as the third Gulf war, will leave a lasting imprint on energy markets well beyond the immediate price moves.

Analysis

The Hormuz blockage persisting through a nominal ceasefire confirms that the physical supply constraint is now decoupled from diplomatic signaling. The $950 million options position betting on falling oil, placed just before the ceasefire announcement, is now deeply offside, creating forced unwind pressure that amplifies the upside in crude. Airlines that already passed through bag fee increases on the prior spike face a second repricing cycle with less consumer goodwill remaining and no competitive cover argument to hide behind.
Iran's claim of ceasefire violation within 24 hours directly reactivates the two-sided Fed rate debate documented in the March minutes. The dovish camp's year-end cut thesis was already conditioned on the conflict proving transitory; a ceasefire that collapses inside 24 hours removes that conditionality entirely. With IMF and World Bank having already ruled out a benign scenario, the Fed hold thesis hardens, sustaining pressure on duration assets and high-multiple equities that had partially recovered on the initial ceasefire announcement.
The Polymarket insider trading episode and the $950 million crude options position placed before the ceasefire announcement together establish a pattern of information-advantage positioning around this conflict's diplomatic events. Regulators scrutinizing prediction markets now have a parallel case in regulated derivatives markets to cite, strengthening the argument that ceasefire announcements are being leaked or anticipated through channels unavailable to the public, which increases the probability of a CFTC or DOJ inquiry into the options trade.

Fed March minutes reveal two-sided rate debate as Iran war clouds inflation outlook

The Fed March minutes showed the committee explicitly conditioning its rate path on war-resolution, with the dovish cut thesis requiring the Iran conflict to prove transitory. A ceasefire that breaks down within 24 hours with Hormuz still blocked eliminates the transitory framing the doves were relying on.

Polymarket accounts net $600k on Iran ceasefire bets placed hours before announcement

The Polymarket accounts that netted $600k on ceasefire bets placed hours before the announcement now sit alongside the $950 million crude options position as parallel evidence of pre-announcement positioning, giving regulators and legislators a two-market pattern rather than an isolated incident.

Delta raises first checked bag fee to $45 as jet fuel costs push airlines to reprice

Delta's bag fee increase to $45, already passed through on the prior oil spike, leaves the carrier with no remaining pricing lever that does not directly hit demand elasticity if crude retraces toward $100 and forces a second cost-recovery round.
