Definition and Scope
Set-off (Muqassah) is the extinction of a debt receivable by a debt payable. It occurs when two parties are simultaneously both creditors and debtors to each other. The standard covers three forms:
- Compulsory set-off: automatic discharge without consent when strict conditions are met.
- Set-off on demand: the creditor with the superior debt can force it by giving up that superiority.
- Contractual set-off: both parties agree to the set-off.
Compulsory Set-Off
Definition: An automatic discharge of two debts without need for request or consent. This occurs spontaneously when conditions are met.
Four conditions must be met:
- Each party must be both creditor and debtor simultaneously.
- Both debts must be equal in kind, type, description, and maturity. If unequal in amount, set-off occurs for the smaller amount; the creditor of the larger debt remains a creditor for the balance.
- Neither debt may be encumbered by a third-party right, such as a pledgee's mortgage.
- The set-off must not violate Shari'ah, including riba or shubhat al-riba concerns.
Example: Bank A holds a Murabahah financing from Customer X (AED 100,000 due in 6 months) and an Islamic savings account for Customer X (AED 100,000 on hand). If both debts mature on the same date, have the same currency, and are not mortgaged, a compulsory set-off occurs: both debts extinguish.
Set-Off on Demand
Definition: A discharge at the request of the party with the SUPERIOR debt. This party can force the other to accept set-off, forgoing their advantage.
Four conditions:
- Each party must be both creditor and debtor.
- The creditor with the superior debt must consent to relinquish the superiority. Superiority can be in quality, such as a mortgaged debt, or duration, such as one debt due now and the other due later.
- Both debts must be similar in kind and type, but not necessarily in maturity or quality.
- There must be no Shari'ah violation.
Example: Bank A owes Customer X AED 50,000 (savings account, due on demand). Customer X owes Bank A AED 100,000 (financing, due in 6 months). Bank A (the on-demand creditor) can demand set-off if it consents to wait for the remaining AED 50,000 until month 6.
Contractual Set-Off
Definition: A discharge by mutual agreement of both parties. This is the most flexible form.
Three conditions:
- Each party must be both creditor and debtor.
- Both parties must mutually consent. This is the key difference from other forms.
- There must be no Shari'ah violation.
Critical Advantage: Unlike compulsory set-off, contractual set-off does NOT require debts to be similar in kind, type, quality, or maturity. The parties can agree to waive those similarity requirements. For example, Bank A could contractually set off a USD 100,000 debt due in 6 months against a EUR 95,000 debt due now. The exchange rate at settlement applies.
Set-Off in Modern Banking (the Debt Set-Off standard)
Consolidation of Debts: Banks and customers often pre-agree (contractually) that any future debts arising from deferred-payment sales will be subject to set-off. This is permissible if both parties consent. It saves documentation each time a dispute arises.
Clearing House Operations: When cheques clear through a central bank or clearing house, set-offs happen between financial institutions. These are usually compulsory or contractual depending on whether the banks have agreed in advance.
Card Networks: Credit card and debit card networks (Visa, Mastercard) enable set-off between member banks through automated clearing. This is permissible under contractual or compulsory set-off rules if the network rules are agreed by all participants.
Currency Swaps and Set-Off (the Debt Set-Off standard)
Riba-Based Currency Swaps are Prohibited: If two institutions swap fixed-rate interest-bearing securities, the underlying debt is interest-bearing and the set-off itself is not permissible under Shari'ah. Banks must ensure that any currency swaps are based on Islamic principles (e.g., swapping Islamic receivables, not interest-bearing bonds).
