Latest on Force majeure
- What is force majeure?
- Force majeure is a contract law doctrine that excuses a party from performance when an extraordinary event beyond their control, such as war or natural disaster, makes fulfilment impossible or illegal. It suspends, but does not void, the obligation.
- Has Iraq declared force majeure on its oil exports?
- Yes. Iraq declared force majeure on all oilfields operated by foreign companies in March 2026 after the Strait of Hormuz was closed by Iran, leaving it unable to route crude through Gulf terminals.Source: Iraq government statement
- What is the difference between force majeure and an act of God?
- An act of God covers natural events only (earthquakes, floods). Force majeure is broader: it includes war, government intervention, and civil unrest. The 2026 Hormuz closure is a force majeure event, not an act of God, because it is a deliberate military action.
- How has the Iran conflict triggered force majeure in shipping?
- Over 3,000 vessels were stranded across the Middle East by March 2026 as the Hormuz closure and port strikes made transit impossible. Shipowners issued force majeure notifications to charterers to suspend delivery obligations without incurring breach-of-contract penalties.Source: IMO
- Can force majeure cancel a contract permanently?
- No. Force majeure suspends the obligation for the duration of the qualifying event. If the event continues long enough, some jurisdictions allow termination, but the default effect is suspension pending resolution, meaning all stranded shipping contracts remain live.
Background
Force majeure (French: "superior force") is a doctrine in contract law that excuses a party from performance when an extraordinary event beyond their control makes fulfilment impossible. Codified in commercial contracts since the nineteenth century, it covers acts of war, natural disasters, and government actions, and requires formal notification plus a causal link between the trigger and the specific obligation that cannot be met.
Since Iran closed the Strait of Hormuz in March 2026, force majeure declarations have cascaded through global energy and shipping markets. Iraq declared force majeure on all oilfields operated by foreign companies, unable to route exports through blocked Gulf terminals . QatarEnergy invoked the clause after Iranian strikes on Ras Laffan destroyed two LNG trains , and more than 3,000 vessels remained stranded as insurers absorbed wave after wave of notifications .
The doctrine has become a proxy indicator of market confidence in conflict duration. When Lloyd"s of London and War risk coverage underwriters invoke it, they signal that hostilities are priced as structural rather than transient. Producers and shippers who cannot invoke force majeure face breach-of-contract exposure on top of physical losses, creating a two-tier crisis between those with legal cover and those without.
