The 8 April ceasefire announcement and parallel discussions around a 45-day truce have not resolved the Strait of Hormuz disruption. They have, for now, capped the worst-case scenario, but tanker traffic remains at a fraction of normal levels and Iran's demand for transit fees signals a structural shift, not a temporary one.
What began as a regional conflict has become a global energy shock, and the question for markets is no longer whether Hormuz was disrupted, but how permanently the disruption changes the pricing floor for oil.
Key takeaways
Around 20 million barrels per day (bpd) of oil and petroleum products normally pass through the Strait of Hormuz between Iran and Oman, equal to about one-fifth of global oil consumption and roughly 30% of global seaborne oil trade.
This is a flow shock, not an inventory problem. Oil markets depend on continuous throughput, not static storage.
If the disruption persists beyond a few weeks, Brent could shift from a short-term spike to a broader price shock, with stagflation risk.
Tanker traffic through the strait fell from around 135 ships per day to fewer than 15 at the peak of disruption, a reduction of approximately 85%, with more than 150 vessels anchored, diverted, or delayed.
A two-week ceasefire was announced on 8 April, with 45-day truce negotiations under way. Iran has separately signalled a demand for transit fees on vessels using the strait, which, if formalised, would represent a permanent geopolitical floor on energy costs.
Markets have begun rotating away from growth and technology exposure toward energy and defence names, reflecting a view that elevated oil is becoming a structural cost rather than a temporary risk premium.

The Strait of Hormuz handles roughly 20 million barrels per day of oil and petroleum products, equal to about 20% of global oil consumption and around 30% of global seaborne oil trade. With global oil demand near 104 million bpd and spare capacity limited, the market was already tightly balanced before the latest escalation.
The strait is also a critical corridor for liquefied natural gas. Around 290 million cubic metres of LNG transited the route each day on average in 2024, representing roughly 20% of global LNG trade, with Asian markets the main destination.
The International Energy Agency (IEA) has described Hormuz as the world’s most important oil transit chokepoint, noting that even partial interruptions may trigger outsized price moves. Brent crude has moved above US$100 a barrel, reflecting both physical tightness and a rising geopolitical risk premium.

Tankers idle as flows slow
Shipping and insurance data now point to strain in real time. More than 85 large crude carriers are reported to be stranded in the Persian Gulf, while more than 150 vessels have been anchored, diverted or delayed as operators reassess safety and insurance cover. That would leave an estimated 120 million to 150 million barrels of crude sitting idle at sea.
Those volumes represent only six to seven days of normal Hormuz throughput, or a little more than one day of global oil consumption.
Updated shipping and insurance data now confirm more than 150 vessels have been anchored, diverted, or delayed, up from the 85 initially reported. The 1.3 days of global consumption coverage from idle crude remains the binding constraint: this is a flow shock, not a storage problem, and the ceasefire has not yet translated into meaningfully restored throughput.
🌋 Trump, volatility and Hormuz.
As tariff shocks collide with a ten year extreme in oil positioning, the margin for error is zero. See the technical markers and safe haven pivots defining the current risk environment.
Oil markets function on continuous movement. Refineries, petrochemical plants and global supply chains are calibrated to steady deliveries along predictable sea lanes. When flows through a chokepoint that carries roughly one-fifth of global oil consumption and around 30% of global seaborne oil trade are interrupted, the system can move from equilibrium to deficit within days.
Spare production capacity, largely concentrated within OPEC, is estimated at only 3 million to 5 million bpd. That falls well short of the volumes at risk if Hormuz flows are severely disrupted.

Indicative market trajectories based on disruption severity
Scenarios for the weeks ahead
1–2 WEEKS
Ceasefire catch-up
Markets face catch-up repricing. Brent could consolidate in the US$105–US$115 range as risk premia unwind. Brent may trade lower (US$95–US$110) if strategic stocks bridge the temporary shortfall.
2–4 WEEKS
Infrastructure blitz
Shifts to structural supply shock. Brent moving toward US$150–US$200 cannot be ruled out. This is the stagflation trigger where energy costs constrain central bank flexibility.
STRUCTURAL
Geopolitical floor
Iran's transit fee demand creates a permanent input cost. The pre-crisis price structure (US$60–US$70) may not return, embedded in insurance and freight rates.
Critical Threshold
US$120 remains the level at which energy inflation becomes a direct Federal Reserve policy problem.
Inflation risks and macro spillovers
The inflationary impact of an oil shock typically arrives in waves. Higher fuel and energy prices may lift headline inflation quickly as petrol, diesel and power costs move higher.
Over time, higher energy costs may pass through freight, food, manufacturing and services. If the disruption persists, the combination of elevated inflation and slower growth could raise the risk of a stagflationary environment and leave central banks facing a difficult trade-off.

What makes the current episode particularly acute is the lack of slack in the global system.
Global supply and demand near 103 million to 104 million bpd leave little spare cushion when a chokepoint handling nearly 20 million bpd, or about one-fifth of global oil consumption, is compromised. Estimated spare capacity of 3 million to 5 million bpd, mostly within OPEC, would cover only a fraction of the volumes at risk.
Alternative routes, including pipelines that bypass Hormuz and rerouted shipping, can only partly offset lost flows, and usually at higher cost and with longer lead times.
Bottom line
Until transit through the Strait of Hormuz is restored and seen as credibly secure, global oil flows are likely to remain impaired and risk premia elevated. For investors, policymakers and corporate decision-makers, the core question is whether oil can move where it needs to go, every day, without interruption.
