Those pressures may feed into consumer inflation through fuel, transport and other production costs, but neither the size nor timing is fixed: it depends on what the route carries, how long disruption lasts, and whether inventories, other suppliers or alternate routes can compensate.
How a shipping disruption can affect oil prices
There are two related price channels. A blocked or delayed route can make oil or refined products less available to buyers, particularly if the cargo has no immediate substitute. At the same time, a ship sent on a longer route may take more time and fuel to reach its destination, while added demand for vessels and higher insurance costs can raise the cost of transportation. These effects can occur together, but their size varies by route and cargo. The U.S. Energy Information Administration (EIA) explains that disrupted trade flows raise the risk of shortages and can cause petroleum-product price spikes in its petroleum trade explainer.
A disruption does not necessarily mean oil has been permanently lost. Cargoes may arrive late or reach buyers by a different route. That can still tighten supply in a particular region or period, and markets may respond to the possibility of future scarcity before a shortage is confirmed. Inventories, spare production capacity, alternative suppliers and the duration of the disruption all influence how much pressure reaches prices.
Why the route and cargo matter
Shipping chokepoints are not interchangeable. Their importance depends on how much oil or fuel normally passes through them, what kind of cargo is involved, and whether buyers can replace it. The figures below use different measures and periods; they should not be read as directly comparable estimates of disruption risk.

| Route or example | What the dated evidence shows | Why it matters |
|---|---|---|
| Bab el-Mandeb | EIA reported that the strait handled 12% of seaborne oil trade and 8% of seaborne LNG trade in the first half of 2023. Its October 2024 report, citing Vortexa data, put average oil flows at 4.0 million barrels per day in 2024 through August, compared with 8.7 million barrels per day for full-year 2023; those periods differ. EIA, February 1, 2024; EIA, October 11, 2024. | A route can remain open yet carry less traffic, or cargo can divert. Flow measures and trade shares describe different things, so neither alone predicts a price change. |
| Strait of Hormuz | EIA reported average oil flows of 20.9 million barrels per day in 2023, about 20% of global petroleum-liquids consumption. EIA, October 11, 2024. | The scale of flows makes sustained disruption consequential, but actual market effects still depend on duration, alternatives and available buffers. |
| Suez and the Cape of Good Hope | For a Persian Gulf-to-Amsterdam-Rotterdam-Antwerp petroleum-trading-hub voyage, EIA’s February 2024 example was 19 days via Suez versus nearly 35 days via the Cape of Good Hope. A separate EIA June 2024 example said an Arabian Sea-to-Europe trip via the Cape takes about 15 days longer than via Bab el-Mandeb and Suez. These are distinct route examples. EIA, February 1, 2024; EIA, June 2024. | Rerouting can preserve delivery while extending the voyage, tying up ship capacity and adding operating costs. |
In a February 2024 route analysis, EIA estimated that fuel for a very large gas carrier using high-sulfur bunker fuel cost about $30,000–$35,000 per day at average 2023 prices. This is a vessel-specific illustration, not a general surcharge for oil shipments; actual costs depend on the vessel, fuel and operating conditions. EIA route analysis.
How shipping costs reach inflation—and why the effect can lag
Higher crude prices can push up fuel costs directly. Freight and energy are also inputs into transporting and producing other goods, so higher costs may reach consumer prices over time. But ocean freight increases do not translate one-for-one into a consumer price index (CPI): the pass-through depends on how persistent the increase is, how much a product relies on the affected route, and whether businesses absorb costs or pass them on. The International Monetary Fund (IMF) discusses these channels in its March 2024 Red Sea analysis and March 2026 analysis.
Two estimates help illustrate why qualifications matter. UNCTAD estimated that global consumer prices could be 0.6% higher by late 2025 if the container freight-rate increases observed between October 2023 and June 2024 had continued through the end of 2025. That was a conditional scenario about container freight, not a measured effect of an oil-route disruption by itself. UNCTAD, June 2024.
An IMF Working Paper published in February 2026 by Jiao, Lan, Liu and Zhao reported that a 100-hour shipping delay was associated with roughly a 0.5-percentage-point increase at the inflation peak five months later in the setting they analyzed. It is a study-specific finding, not a universal rule for every route, country or type of disruption. IMF Working Paper 26/26.
What determines who feels the price pressure most
- Exposure to the affected cargo: A region that depends on oil or refined products moving through the disrupted route may face tighter local supply than one with other sources.
- Alternatives and buffers: Inventories, spare capacity, alternate shipping routes and available suppliers can cushion a shock or help trade adjust.
- Household and national energy dependence: Import dependence and limited buffers make economies more exposed. The IMF’s March 2026 analysis identifies energy importers and countries with limited buffers as particularly vulnerable.
- What the route carries: Crude oil, refined fuels, LNG and containerized goods are different markets. A statistic about container freight or all maritime trade cannot be treated as a direct measure of oil supply.
- Duration and adjustment: A short delay may be managed through inventories or rerouting; a prolonged disruption can leave less time for those adjustments and sustain pressure.
Trade can adapt, which may moderate a shock even when it does not eliminate the added cost. In an example that was not itself a shipping-route closure, EIA described European diesel buyers replacing Russian supply after sanctions with more distant cargoes. The tighter market also affected U.S. prices as exports increased; EIA says those price effects subsided as trade routes adjusted. EIA petroleum trade explainer.

In its March 2024 account of the Red Sea and Panama Canal disruptions, the IMF said the Suez Canal carried about 15% of global maritime trade volume and the Panama Canal about 5%. The Suez Canal’s trade volume fell 50% year over year in the first two months of 2024, while Cape of Good Hope transits were 74% above their prior-year level. The IMF cited an average delivery-time increase of 10 days or more for diversions around the Cape. These figures describe all maritime trade or shipping activity, not oil alone. IMF, March 7, 2024.

For a more recent, oil-specific episode, EIA reported that front-month Brent futures ranged from $72 to $118 per barrel in the second quarter of 2026 amid continuing Hormuz-related flow disruption. That is an observed range during a particular quarter, not a forecast or a standard increase caused by any route disruption. EIA, July 15, 2026. The World Bank’s April 2026 commodity outlook discussed the shock and projected higher annual energy prices on the assumptions that acute disruption would ease and shipping would gradually recover; that projection likewise depends on its stated assumptions, rather than describing a permanent price outcome. World Bank, April 28, 2026.
For a household, a route disruption can therefore show up first as a change in fuel or transport costs and, if pressures persist, in prices of goods that rely on affected energy or shipping. The size and timing cannot be inferred from a route’s headline trade share alone: the cargo at risk, the available substitutes, the length of disruption and the importing economy’s buffers all matter.
