Update to CH Advisory 21-338
Please be advised that CME will support for flexible fixing date offset for overnight index swaps (OIS) in the New Release environment on Wednesday, November 17, 2021 and in the Production environment on Monday, December 6, 2021. This interest rate swap convention is also known as a “Lookback”, where the rate for each business day in a calculation period is determined on the basis of the rate observed for a certain number of business days prior to such date. This enhancement allows the OIS floating coupon to be known ahead of the calculation period end date.
