Set-off applies one enforceable obligation against a mutual counter-obligation, reducing the amount payable while remaining subject to contract, law, and insolvency limits.
Set-off is the application of one enforceable monetary obligation against a counter-obligation between the same parties, reducing the amount that must be paid separately. In lending, banking, derivatives, trade credit, and insolvency, set-off can reduce exposure when the required contractual and legal conditions are met.
Set-off is more than subtracting two accounting balances. The claims usually must satisfy rules on mutuality, legal capacity, maturity, currency, enforceability, notice, and insolvency. The exact requirements vary by agreement and jurisdiction.
Suppose Party A owes Party B $100,000, while Party B owes Party A $35,000. If the obligations are eligible for set-off, the smaller claim is applied against the larger one:
| Position | Before set-off | After set-off |
|---|---|---|
| A owes B | $100,000 | $65,000 |
| B owes A | $35,000 | $0 |
Set-off reduces payment flows and gross credit exposure, but it does not settle disputes over whether either claim is valid, due, assignable, or legally mutual.
The same two legal persons generally must owe each other. A debt owed by a parent usually cannot be set off against a receivable from its subsidiary merely because the entities are in one corporate group.
The parties usually must act in the same legal capacity. Funds held as trustee, escrow agent, fiduciary, or custodian may not be freely set off against a personal debt of the beneficiary or account holder.
The relevant claim must be valid and enforceable. Some rights require both obligations to be due, while contracts or laws can address unmatured, contingent, disputed, or future claims differently.
Cross-currency set-off can require an agreed conversion rate, valuation time, and payment currency. Without workable terms, currency differences can prevent or complicate exercise.
The account agreement, credit agreement, assignment notice, consumer rule, insolvency stay, court order, or applicable law can restrict set-off.
When a customer deposits money with a bank, the bank generally owes that amount to the customer under the account terms. If the same customer also owes a matured loan to the bank, the two obligations can support set-off if the contract and law permit it.
A business owes its bank $120,000 under a defaulted loan and holds $40,000 in an ordinary deposit account at the same bank. Assume both obligations belong to the same legal entities in the same capacities and the bank has an exercisable contractual and legal set-off right.
The bank applies $40,000 against the loan, reducing the loan balance to $80,000.
The result changes if:
UCC Section 9-340 addresses how a bank’s set-off rights interact with a security interest in a deposit account. The general rule and exceptions depend on who maintains the account and how the competing security interest is perfected by control.
This is not a simple “bank always wins” rule. Analysts should identify the account bank, debtor, secured party, control arrangement, source of the bank’s claim, and applicable subsection.
Commercial agreements can expressly permit one party to deduct amounts owed by the counterparty. Important terms include:
An affiliate set-off clause may attempt to reach obligations across a corporate group, but enforceability and insolvency treatment require separate analysis. Contract wording cannot always manufacture legal mutuality.
U.S. Bankruptcy Code Section 553 generally preserves qualifying rights of set-off that exist under other law, subject to stated exceptions. It does not independently create the right. Among other matters, Section 553 addresses mutual prepetition debts and certain claims acquired or obligations incurred around insolvency.
The automatic stay under Section 362 can restrict collection and set-off after a bankruptcy filing unless relief or an exception applies. Financial contracts can also have specialized safe-harbor provisions.
The practical review should ask:
Bankruptcy outcomes are procedural and fact-specific; a pre-filing contract clause is not the end of the analysis.
For U.S. consumer credit cards, Regulation Z Section 1026.12(d) generally prohibits a card issuer from offsetting card debt against funds the cardholder has on deposit with the issuer. The official interpretation also treats certain account freezes as the functional equivalent of an offset.
The rule includes specified treatment for consensual security interests, court processes, and agreed automatic payment plans. A routine account clause is not necessarily a qualifying consensual security interest. This restriction should not be generalized to every deposit and loan relationship.
| Concept | Main distinction |
|---|---|
| Set-off | Applies independent mutual obligations against each other |
| Recoupment | Reduces a claim using a closely connected claim arising from the same transaction or relationship, depending on law |
| Netting | Calculates a net obligation across covered transactions, often under a master agreement or payment system |
| Security interest | Property interest securing an obligation |
| Payment application | Allocates a payment among principal, interest, fees, or multiple debts |
The labels can overlap in business usage. Legal characterization matters most during default and insolvency.
An invalid set-off can create repayment, damages, stay-violation, consumer-compliance, fiduciary, or priority disputes. Even a valid right can be limited by insufficient counter-obligations, trapped funds, timing, or legal process.
Set-off rules vary substantially by contract, transaction, and jurisdiction. This page is educational and is not legal, bankruptcy, banking, accounting, or personalized financial advice.
