In English law, economic duress refers to situations where one party exerts illegitimate commercial pressure, forcing another to enter or modify a contract against their free will.
Economic duress involves wrongful or improper threats, typically economic in nature, leaving the pressured party with no reasonable alternative but to agree. Contracts or contract modifications entered under economic duress may become voidable.
Contracts formed or modified under economic duress can be rescinded, with the parties potentially returned to their original positions. Damages may be available if applicable.
The doctrine protects parties from coercive practices, preserving commercial fairness and genuine freedom of contract.

Atlas threatened to withhold deliveries unless Kafco agreed to substantially higher carriage charges, despite an existing contract. The court held the variation unenforceable for lack of fresh consideration and because Kafco’s apparent consent was obtained through economic duress.
Armstrong, chairman of Landmark Corporation, threatened to have Barton, the managing director, killed unless he executed a deed purchasing Armstrong's shares. The Privy Council held that a contract may be avoided for physical duress even if the threats were not the main reason for entering the agreement.
CTN Cash and Carry paid £17,000 to Gallaher for stolen cigarettes after Gallaher threatened to withdraw credit facilities. Gallaher genuinely but mistakenly believed payment was owed. The Court of Appeal held that lawful commercial pressure exercised in bona fide pursuit of a believed debt did not constitute economic duress enabling recovery of payment.
D & C Builders, a small building company in financial difficulties, were owed £482 by Rees. His wife offered £300 in full settlement, threatening they would receive nothing otherwise. The Court of Appeal held the payment did not discharge the debt as there was no consideration and the agreement was obtained through intimidation.
The Paos sold their company shares to Fu Chip, receiving Fu Chip shares as payment with restrictions on selling. They later demanded a guarantee from the Laus against share price falls, threatening not to complete unless given. The Privy Council held valid consideration existed and rejected the economic duress defence, establishing key principles on past consideration and economic duress.
Times Travel, a travel agent reliant on PIAC for airline tickets, was pressured into signing a new contract waiving claims for unpaid commission. The Supreme Court held that lawful act economic duress requires a 'bad faith demand' - the threatening party must not genuinely believe in its legal entitlement. As PIAC genuinely believed it had a defence, duress was not established.
The ITF 'blacked' a flag-of-convenience vessel at Milford Haven, compelling the shipowners to pay $80,000 including $6,480 to a Welfare Fund. The shipowners sought recovery of the Welfare Fund contribution on grounds of resulting trust or economic duress. The House of Lords held there was no trust, but the demand was not connected with terms and conditions of employment, constituting recoverable economic duress.
