ISDA master agreement
Last updated: November 10, 2025
Quick definition
ISDA master agreement is an industry standard agreement developed by the International Swaps and Derivatives Association that governs all derivatives trading between a hedge fund and its swap dealer counterparties, establishing the legal framework for over-the-counter derivatives transactions.
An ISDA master agreement creates the legal foundation that hedge funds need to trade
It's like a master rulebook that covers all future trades between two parties. The agreement establishes fundamental legal terms that apply to every transaction. These terms include basic promises each party makes, known as representations. They also include ongoing obligations they must meet, which are called covenants. The agreement specifies situations that would trigger a default and conditions that would allow either party to end the relationship. It also establishes rules for combining multiple payments into a single net amount.
Hedge funds must sign ISDA agreements with dealers before they can engage in any swaps or derivatives transactions. This requirement ensures that both parties understand their legal obligations. It also provides clear procedures for resolving disputes or handling defaults when they occur.
The ISDA documentation system consists of four main components that work together to create a complete trading framework. Understanding how these pieces fit together helps explain why the system works effectively for complex financial transactions.
The ISDA master agreement provides the standard legal terms that apply to all trades between the parties. This document contains the basic rules that govern the relationship, but it's designed to be modified for specific situations.
The Schedule allows the hedge fund and dealer to modify specific provisions in the Master Agreement. This is where they negotiate custom terms that the standard agreement does not include. For example, they might adjust default triggers or change how disputes will be resolved.
Individual trade Confirmations specify the exact details of each particular transaction. Every time the parties execute a trade, they create a Confirmation that references the Master Agreement but provides the specific terms for that deal.

The Credit Support Annex governs collateral requirements. This document receives separate treatment due to its complexity and importance in managing counterparty risk.

This document addresses practical concerns about counterparty risk—the risk that the other party might not be able to fulfill its obligations. The CSA establishes clear rules for several key areas. First, it determines when and how collateral must be delivered. Second, it specifies requirements for additional collateral when the value of existing trades changes. Third, it lists what types of assets qualify as acceptable collateral. Fourth, it addresses whether interest is paid on posted collateral and at what rate. Finally, it includes standard legal terms that govern the relationship between the party providing collateral and the party receiving it.
CSA negotiations typically focus on operational details that significantly impact trading costs and efficiency. The most important areas include timing for
Other key negotiation points include threshold amounts that trigger initial collateral requirements and detailed specifications of what assets qualify as acceptable collateral. Parties negotiate rights to substitute one type of collateral for another and dispute resolution procedures for disagreements about collateral valuations. They also address
ISDA master agreements include special provisions that address the unique characteristics and risks of hedge fund operations. Unlike traditional asset managers, hedge funds often use more complex strategies and higher leverage. They may also have less regulatory oversight, which creates additional risks for their trading counterparties.
The Schedule negotiations focus on
These hedge fund-specific termination events cover several scenarios.
Other important triggers include adverse events affecting the investment manager, such as loss of key personnel or regulatory sanctions.
These provisions ensure that dealers can exit trading relationships when circumstances suggest the hedge fund may no longer be able to honor its trading obligations.
When hedge funds work with prime brokers, potential conflicts can arise between ISDA Master Agreements and prime brokerage agreements. Understanding these potential conflicts helps hedge funds protect their interests.
Some prime brokers attempt to incorporate their own agreement terms into other contracts. These efforts can override more favorable terms that exist in trading agreements, including ISDA master agreements or
Hedge funds should ensure that prime brokerage agreements do not adversely affect their rights or obligations under existing trading agreements. The most important areas requiring protection include collateralization requirements that determine how much collateral the fund must post. More collateral means higher costs and less capital available for investments.
Other key protection areas include set-off and
The
Single loan or security total return swaps qualify as "security based swaps" under SEC jurisdiction. This means they fall under Securities and Exchange Commission rules and oversight. In contrast, portfolio-based total return swaps fall under Commodity Futures Trading Commission jurisdiction as regular "swaps."
A 2023 federal court decision in CFTC v. Archegos Capital Management LP provided additional clarity about these jurisdictional boundaries. The court ruled that total return swaps based on exchange-traded funds are considered security-based swaps under SEC jurisdiction. However, those based on broad-based security indices remain under CFTC oversight.
The SEC's security-based swap regulatory regime became effective in November 2021. This regime requires security-based swap dealers to register with the SEC and comply with comprehensive rules. These include business conduct standards that govern how dealers interact with customers and documentation requirements that specify what paperwork must be maintained. The rules also include margin requirements that largely parallel existing CFTC regulations but apply to different products and counterparty relationships.
Although total return swaps may not face mandatory clearing requirements through
These margin requirements can increase the total cost of total return swap transactions. They require additional collateral posting beyond what the parties might otherwise negotiate privately. This means hedge funds may need to tie up more capital in collateral, reducing the amount available for investments and potentially affecting overall returns.
