Strait of Hormuz effectively closed to commercial shipping since 28 Feb 2026, cutting seaborne oil and LNG flows
On 28 February 2026 the Strait of Hormuz was declared shut; commercial transits have since collapsed to a small fraction of pre-crisis levels, producing a sustained seaborne oil and LNG supply shock that raises war-risk insurance and freight costs and shifts fiscal/FX exposure between hydrocarbon exporters and fuel importers (ongoing, through Nov 2026).
The desk brief
On 28 February 2026 the Strait of Hormuz was declared shut; commercial transits have since collapsed to a small fraction of pre-crisis levels, producing a sustained seaborne oil and LNG supply shock that raises war-risk insurance and freight costs and shifts fiscal/FX exposure between hydrocarbon exporters and fuel importers (ongoing, through Nov 2026).
Persistent near-closure of Hormuz reduces physical seaborne flows and raises war-risk premiums, which supports higher global benchmark oil prices and can bolster fiscal receipts and FX for African hydrocarbon exporters. Conversely, African importers face higher fuel and freight bills that tighten external balances and fiscal space; pass-through to local inflation and FX depends on policy buffers and hedging capacity.
Monitor US–Iran diplomatic talks or any Iran reopening proposal and IMF PortWatch daily transit counts for an observable return toward pre-crisis transit volumes.
