Gunfire in Hormuz and the Biggest Daily Oil Supply Shock on Record
At least three commercial vessels were hit by gunfire in the Strait of Hormuz on April 22, according to maritime security sources and UKMTO-linked reporting, with crews reported safe but one ship’s bridge damaged. The incidents came as the Iran war and the ongoing Hormuz disruption pushed the global oil market into what the IEA now describe as the largest daily oil supply shock ever recorded. Supply losses have exceeded 12 million barrels per day, while the IEA said global oil supply fell by 10.1 million barrels per day in March and called it the largest disruption in history. The current shock is not only about crude. It is also disrupting LNG, refined products, fertilizer supply chains, and marine routing, with Hormuz having handled about one-fifth of global oil and LNG flows before the war.

Direct attacks at sea are now colliding with a record supply shock
The latest Hormuz story is no longer only about restricted passage or delayed cargoes. It now includes direct gunfire against commercial ships at the same time that the war-driven Gulf outage has become the biggest daily oil supply loss ever recorded. That combination matters because it links physical danger on the waterway with a supply disruption already large enough to rank above every previous daily oil shock.
- Security signal: three commercial vessels were fired upon in Hormuz.
- Energy signal: daily oil supply losses have moved above 12 million barrels per day.
- System signal: crude, LNG, refined fuels, and marine trade are now being hit together.
The market is dealing with both a live maritime attack pattern and a record-size supply deficit at the same time.

| Commercial ships are being shot at again |
Three commercial vessels were hit by gunfire in Hormuz on April 22, with one ship sustaining bridge damage.

The security threat has moved beyond passive restriction into active attacks on merchant traffic. | Even legally movable cargoes become harder to insure and schedule. | Higher war-risk pricing and greater vessel hesitation. | Shipowners, insurers, charterers, cargo owners. |
| The current oil supply hit is historically unmatched on a daily basis |
The shock has exceeded 12 million bpd, while the IEA reported a 10.1 mb/d supply drop in March and called it the largest disruption in history.
12m+ bpd lost
10.1 mb/d March drop
largest in history

The market is no longer comparing this to routine outage events but to the most severe energy disruptions on record. | Benchmark pricing, replacement sourcing, and emergency stock policy all shift upward in importance. | Higher crude prices and stronger backwardation pressure. | Refiners, governments, stockpile managers, traders. |
| This shock is larger by daily loss than the 1970s oil crises |
It has surpassed the peak daily losses seen during the 1973-74 Arab oil embargo and the 1978-79 Iranian Revolution.
bigger daily loss
above 1973-74
above 1978-79

The comparison point for this event is now historical-systemic, not merely regional. | Policy and market responses are more likely to become structural rather than tactical. | More urgency around stock releases, rerouting, and substitution. | IEA members, OPEC+ watchers, policymakers. |
| LNG has been hit at the same time as oil |
20% of global LNG production has been disrupted, and IEA data show Hormuz previously handled around one-fifth of global oil and LNG flows.
20% LNG disrupted
one-fifth of flows

This is an energy-system shock, not a crude-only shock. | Utilities and LNG buyers have to compete for replacement cargoes while oil users face their own supply squeeze. | Broader fuel substitution and higher gas procurement stress. | Asian utilities, LNG traders, gas-intensive industries. |
| The volume collapse through Hormuz remains severe |
IEA says crude and product flows through Hormuz fell from around 20 mb/d before the war to just over 2 mb/d in March.
20 mb/d to just over 2
March collapse

The lane is not just expensive or risky. It is operating at a fraction of normal throughput. | Alternative routes and ports cannot fully replace the lost movement volume. | Regional shut-ins and prolonged delivery delays. | Saudi, UAE, Kuwait, Iraq, Qatar, Asian importers. |
| The shock is spreading west as well as east |
Recent acute shortages first hit Asia and are increasingly reaching Europe, while alternative routes out of Saudi Arabia and the UAE have only partly offset losses.
Asia hit first
Europe increasingly affected
partial offset only

The market is transitioning from regional disruption to wider international supply stress. | Importers farther from the Gulf face tighter competition for replacement barrels and cargoes. | More Atlantic Basin strain and stronger destination competition. | European refiners, African importers, Atlantic traders. |
Hormuz Shock Severity Lab
This tool measures the current crisis across two linked dimensions: direct maritime violence and the size of the resulting oil-and-gas supply disruption. It helps readers test whether the market is still dealing with a traffic choke, a major energy shock, or a full-system global supply event.

Operational readout
The model combines maritime attack intensity and energy-system disruption because the current crisis is strongest where those two forces overlap.
The current Hormuz crisis looks like a full-system energy and shipping shock rather than a simple corridor disruption.
| Stage | System picture | Market behavior | Main driver |
|---|---|---|---|
| Stage 1 Corridor stress |
Hormuz is disrupted, but losses are still regionally containable. | Prices rise, but the wider system still absorbs much of the shock. | Routing risk |
| Stage 2 Major oil shock |
Oil losses dominate the market and push balances into deficit. | Replacement sourcing and stock policy become central. | Volume loss |
| Stage 3 Multi-fuel shock |
Crude, LNG, and products all tighten together. | Substitution and wider fuel stress spread across regions. | Cross-fuel disruption |
| Stage 4 System shock |
Direct attacks on shipping and record energy losses reinforce each other. | Trade, pricing, and policy all behave as if the disruption is historic in scale. | Maritime violence plus supply loss |
The defining feature of the current Hormuz crisis is not only that ships are being fired on, or only that supply is collapsing. It is that both are now happening at once, which is why the event is being measured as a record daily oil shock rather than a standard chokepoint disruption.
