ISDAISDA
The International Swaps and Derivatives Association is the industry body for over-the-counter derivatives. Its standard ISDA Master Agreement sets the legal terms — including what happens on default — for most swaps between institutions.
ISDA is the trade body behind the standard legal paperwork for over-the-counter derivatives. Its Master Agreement sets out how two firms trade swaps with each other, and what happens if one of them defaults. Understanding it helps explain how counterparty risk is managed outside exchanges. Rules differ by country, especially on whether netting holds up in insolvency.

ISDA in plain words
ISDA's goal is to make derivatives markets safe and efficient so that users can manage risk effectively.1
Its flagship document, the ISDA Master Agreement, is the umbrella contract two firms sign once to cover all their OTC derivatives deals.2
It was founded by a group of large international swap dealers based in New York.3
How an ISDA relationship works
Sign the Master Agreement
Choose a version — 1992 and 2002 are the most common.2
Negotiate the Schedule
The parties tailor terms such as termination events and governing law.
Add collateral terms
A credit support document sets how Margin is posted.
Trade and confirm
Document each trade with a confirmation, which becomes part of the single master agreement.2
Net routine payments
Net payments on the same day so only one amount changes hands while both firms are healthy.2
Close out on default
Know the difference: close-out netting applies when the agreement is terminated, for example after a default.2
Worked examples
Example 1 — Payment netting
$2m single paymentHypothetically, on one day Bank A owes Bank B $5 million on a swap and Bank B owes Bank A $3 million in the same currency.
| Gross payments | $5m + $3m = $8m |
| Net payment | $5m − $3m = $2m from A to B |
Only the net amount moved, because payment netting applies in normal business.2
Example 2 — Close-out netting
$8m net claim instead of $14m grossHypothetically, Fund X defaults with three trades: Bank Y is owed $10m, $4m, and owes X $6m.
| Owed to Y | $10m + $4m = $14m |
| Owed to X | $6m |
| Net claim | $14m − $6m = $8m |
After the default, all open trades were netted into one amount, as far as the law allowed in each jurisdiction.4
Example 3 — Without netting
Much higher exposureSame trades, but hypothetically netting is not enforceable where X is based.
| Y must pay X | $6m |
| Y claims in insolvency | $14m, recovery uncertain |
Whether close-out netting holds up is a separate legal question from whether the party was allowed to trade derivatives at all.5
ISDA OTC trading vs exchange trading
| Aspect | ISDA (OTC) | Exchange |
|---|---|---|
| Contract terms | Negotiated per relationship | Standard contract specs |
| Counterparty | The other firm | Clearing house |
| Default handling | Close-out netting under the agreement | Clearing house rules |
| Flexibility | High | Low |

Going deeper
Read as far as you need. Each level builds on the one before it.
One agreement, many trades
Beginner
All trades sit inside one agreement rather than many separate contracts.2 That single-agreement idea is what makes netting possible.
Two kinds of netting
Intermediate
Legal enforceability
Advanced
Close-out netting clauses are built into widely used master agreements, including the ISDA Master Agreement and the IFEMA.4 Whether they hold up is a legal question that differs by country, which is why ISDA gathers legal opinions on it.
Common mistakes
Assuming netting always works
Enforceability depends on local insolvency law.
Mixing up versions
1992 and 2002 terms differ on close-out.
Ignoring the Schedule
Key terms are changed in the Schedule, not the printed form.
Confusing ISDA with a regulator
ISDA is an industry body, not a government agency.
