Wood Mackenzie: Strait of Hormuz closure risks greatest global energy supply shock in decades
What happened
Wood Mackenzie lays out three Strait of Hormuz disruption scenarios and says a prolonged closure would be the largest recent shock to oil and LNG markets. The report explicitly flags large volumes of crude and LNG being inaccessible to markets, which makes the analysis operationally real for projects that import feedstock or rely on marine logistics. Watch carrier notices, insurer surcharges, and supplier quote behavior as the next concrete market signals
Buyer takeaway
Treat this as a portfolio‑level supply and logistics risk that should be reflected in contract pass‑through, contingency, and mobilisation language
Cost / money
Directional upward pressure on feedstock, shipping, and commissioning fuel costs; expect suppliers to seek pass‑throughs and contingencies
Supplier / commercial
Shipping and storage providers gain short‑term leverage; expect carriers and terminals to negotiate premium terms for capacity or expedited handling
Safety / operations
Schedule compression from supply shocks can drive rushed handovers; maintain strict acceptance criteria to protect safe commissioning
What to watch
Watch for carrier/insurer advisories, port notices, and suppliers shortening quote validity or inserting mobilisation‑only pricing
Key facts
- Scenarios range from near‑term reopening to extended disruption
- Report cites large volumes of crude and LNG currently inaccessible

Meanwhile, over 80 million tpy of LNG supply, equivalent to around 20% of global supply, remains inaccessible to global markets. In its new report, Wood Mackenzie has shared three distinct scenarios: Quick Peace, Summer Settlement, and Extended Disruption
