OTC IRS Curves

OTC/IRS data contains the daily curve data generated for cleared Interest Rate Swaps.

CME Clearing independently generates valuation curves for all currencies in the cleared OTC IRS products offering. These valuation curves are used in both the initial margin and settlement variation (e.g., variation margin) calculations.

For curve construction, CME Clearing uses input instruments based on market feedback, liquidity analysis and quote availability. Inputs are reviewed periodically, which is designed to ensure that CME Clearing’s valuation curves reflect changes in the market standard specific to each currency. A typical combination of instruments is the deposit rate on the short end, followed by futures or FRAs, and finally swaps on the long end of the curve.

CME Clearing sources quotes from multiple data providers. The quotes are then validated against one another and blended together to derive inputs that are used in curve generation.

OTC / IRS Interpretation

What does the data represent?

CME Clearing independently generates valuation curves for all currencies in the cleared
OTC IRS products offering. These valuation curves are used in both the initial margin and
settlement variation (e.g., variation margin) calculations.

How is the data computed?

Bootstrapping a curve is the process of implying zero rates from the market quotes of
input instruments. Interpolation is an essential part of curve generation and is used to
generate daily zero rates along the entire term structure.
An appropriate bootstrapping algorithm and interpolation scheme are selected to
provide for accurate repricing of input instruments and compliance with general term
structure expectations.

How large are these files?

United States dollar is around 800 KB a day. All other currencies range from 300-800 KB daily.
