Strait of Hormuz Oil Disruption — May 2026: Live Supply Impact & Price Tracker
The May 2026 Hormuz crisis is the largest physical oil-supply disruption since the 1990–91 Gulf War. Brent has cleared $90/bbl, Singapore Jet is +37 %, and roughly 3.6 million barrels per day of crude flow is either re-routed, delayed or off-market. This page tracks the disruption indicator-by-indicator and explains who absorbs the shock.

The 20 mb/d chokepoint — and why bypass capacity is a myth
Hormuz handles ~20 mb/d of crude + condensate (≈ 21 % of global oil consumption) and ~30 % of seaborne LNG. The bypass infrastructure looks impressive on a map but is structurally undersized:
| Pipeline | Owner | Nameplate | Realistic spare |
|---|---|---|---|
| Petroline (East-West) | Saudi Aramco | 5.0 mb/d | ~2.0 mb/d |
| ADCOP (Habshan-Fujairah) | ADNOC | 1.8 mb/d | ~0.5 mb/d |
| Goreh-Jask | NIOC | 0.3 mb/d | ~0.3 mb/d (Iran-only) |
| Iraq-Turkey (ITP) | KAR/SOMO | 1.0 mb/d | 0 (closed since 2023) |
| Total realistic bypass | ≈ 3 mb/d |
Even fully optimised, the alternative routes can absorb less than 15 % of the volume that normally transits the strait. The detailed engineering breakdown is in our alternative shipping routes analysis.
What is actually disrupted right now
- Crude flows: Kpler shows 17–20 VLCC daily transits vs. the 24–27 baseline. Net = roughly 2.8 mb/d off the export curve for May.
- LNG: Qatar (76 Mt/y) loadings reduced to one cargo every 18 h vs. the normal 4–5/day cadence.
- Refined products: Singapore Jet +37.6 %, ULSD +22 % since 1 May. Mechanics in the jet-fuel crunch explainer.
- Insurance: war-risk premium 0.07 % → 0.31 %, adding $1.4–1.8 M per VLCC voyage. Translation into $/bbl in the war-risk premium breakdown.
- AIS dark traffic: at least 6 confirmed AIS shutdowns in the eastern approaches in 72 h (why tankers go dark).
Brent price scenarios for H2 2026
| Scenario | Trigger | Brent peak | Comment |
|---|---|---|---|
| Base | Current grey-zone harassment continues | $92–98 | Already priced in |
| Bull | One mining incident OR US/Iran direct exchange | $115–135 | SPR releases trigger above $110 |
| Bear | De-escalation deal + IAEA verification | $75–82 | Premium collapses in 2–3 weeks |

Who absorbs the shock
- Asia (China, India, South Korea, Japan) import 76 % of Hormuz crude. China has accelerated SPR draws; India has switched 0.4 mb/d of Iranian barrels to Russian Urals at discount.
- Europe is less directly exposed on crude but fully exposed via jet fuel and LNG. The Med-2 refinery margin has collapsed below $4/bbl.
- GCC producers see a windfall on price but a structural threat to the predictability premium their barrels carry.
- Africa absorbs the inflation second-round — see the pan-African inflation tracker.
How we track the disruption
- AIS + dark-vessel SAR: ESA Copernicus Sentinel-1 + Planet Labs SkySat tasking on incidents
- Cargo flows: Kpler crude flows API, cross-checked against EIA Weekly Petroleum Status
- Insurance: Lloyd's Joint War Committee listed-areas updates
- Geopolitical events: UKMTO advisories + primary IRGC / CENTCOM statements

FAQ
How much oil is actually disrupted by the May 2026 Hormuz crisis? Roughly 3.6 million barrels per day are either re-routed, delayed or off-market, against a baseline transit of about 20 mb/d. Most of the impact is timing-driven (slower transit, AIS-dark crossings) rather than outright cancellation.
Will the Strait of Hormuz close completely? Highly unlikely. A formal closure would constitute an act of war under UNCLOS and trigger a CENTCOM response. Iran's strategy is to constrain transit economically without crossing that legal threshold.
What is the Brent price forecast if Hormuz disruption worsens? Base case is $92–98/bbl. A single mining incident or direct US–Iran exchange would lift Brent into the $115–135 range, at which point coordinated SPR releases become the most likely backstop.
Can Saudi Arabia and the UAE re-route enough crude to compensate? No. Combined realistic spare bypass capacity via Petroline and ADCOP is about 3 mb/d — less than 15 % of normal Hormuz throughput. Bypass cannot replace the strait at any meaningful scale.
How quickly do jet fuel and diesel prices react to a Hormuz disruption? Faster than crude. Singapore Jet and ULSD cracks moved within 72 hours of the first IRGC boarding, with Jet +37.6 % and ULSD +22 % vs. 1 May 2026.
Which countries are most exposed to a Hormuz oil disruption? China, India, South Korea and Japan, which jointly absorb about 76 % of Hormuz-origin crude. Europe is exposed indirectly via jet fuel, LNG and Med refinery margins.
