Are the difficulties caused by COVID-19 grounds for refusing or delaying the performance of financial contracts (e.g., financing agreements; OTC derivatives, etc.) in order to obtain more advantageous conditions, or to terminate them?
Under Portuguese law, as a general rule, the risk of circumstances happening after the signing of the contract, which jeopardize the economic balance envisaged by the parties at the time of contracting, shall be borne by the debtor, that is, the one who is bound to perform, since only the impossibility of performance, for reasons not attributable to the debtor, exonerates the debtor without further consequences. To make applicable the impossibility framework, the supervening circumstance must make the performance absolutely impossible, as even an extremely serious and unforeseeable hardship is not considered sufficient, nor is a practical or economic "impossibility", or the exception of the debtor’s ruin. Such cases, the respective "conditions of admissibility" having been verified, set motion the application of Article 437 of the Civil Code, the institute that regulates the "change in circumstances" which is applicable when performance is still possible but entails to the debtor an unexpected loss at the time of the contract and makes unfair the claim for performance by the part of the creditor.
