Derivative transactions may include collateral offered by the parties involved. These transactions require both parties to document the security provided by either one. Therefore, they may use a credit support annex (CSA). This document may give rise to a collateral choice option. Before discussing this option, it is crucial to understand what a CSA is.
What are Credit Support Annexes?
Credit support annexes are a document that supports over-the-counter (OTC) derivative transactions. They record the terms of the provision for the security offered by the parties in those transactions. Essentially, CSAs are a part of a standard contract from the International Swaps and Derivatives Association (ISDA). They provide a legal foundation for OTC derivatives trading.
The primary focus of credit support annexes is to mitigate counterparty credit risks. Since OTC derivatives come with lower regulations and get traded as speculation, they involve higher risks. Therefore, CSAs can help document the collateral each part offers in these transactions. CSAs can also help cover losses for the parties involved in the future.
Some CSAs also allow the parties involved to post various currencies as collateral in a derivative transaction. This feature allows the part posting the collateral to choose the currency they can post. Moreover, it also gives rise to an option, which comes in the form of the collateral choice option.
What is a Collateral Choice Option?
Collateralized contracts have become more common in many transactions over the years. Most of these contracts offer cash as collateral. However, some of it may be in different currencies. CSAs allow the parties involved to provide currencies as collateral. This feature of collateralized contracts leads to optionality. This optionality is known as the collateral choice option.
A collateral choice option provides parties with the choice between posting different currencies in a CSA. This option comes with its own value. However, calculating it is not as straightforward. Several models can be used to estimate a collateral choice option value. The inclusion of collateral choice options also complicates credit support annexes due to the implications involved.
How does a Collateral Choice Option work?
A collateral choice option offers a party the ability to change the type of security in a derivative transaction. This party is known as the collateral-posting party. Due to the nature of these contracts, this party can choose the currency of the deposited collateral. However, the existence of this choice in a CSA complicates the valuation of the underlying option. Most analysts use several assumptions when calculating the value of the collateral choice option.
A collateral choice option defines the optionality in a collateralized contract. It provides the collateral-posting party with a collection of collateral securities. Furthermore, it encourages them to optimize their choice of collateral security. However, the parties must determine the collateral rates of each currency within the collateral currencies.
Collateralized contracts include credit support annexes to document the underlying terms for the collateral offered. These may also come within various currencies provided as collateral. Due to this feature, collateralized contracts give rise to a collateral choice option. This option offers the collateral-posting party to select the type of security provided in a derivative transaction.
