ISDA Statement on RBSL CDOR Announcement

ISDA has published the following statement in response to today’s announcement by Refinitiv Benchmark Services (UK) Limited (RBSL) on the future cessation of all remaining Canadian Dollar Offered Rate (CDOR) tenors.

Today’s announcement constitutes an index cessation event under the ISDA 2020 IBOR Fallbacks Supplement, the 2021 ISDA Interest Rate Derivatives Definitions and the ISDA 2020 IBOR Fallbacks Protocol. As a result, the fallback spread adjustment published by Bloomberg is fixed as of the date of the announcement for all remaining CDOR settings.

“RBSL specifically announced that calculation and publication of all remaining CDOR tenors will cease immediately after final publication on June 28, 2024. The fallbacks (ie, to the adjusted risk-free rate plus spread) will automatically occur after June 28, 2024 for outstanding derivatives contracts that incorporate the IBOR Fallbacks Supplement, including as a result of both parties adhering to the ISDA 2020 IBOR Fallbacks Protocol, or the 2021 ISDA Interest Rate Derivatives Definitions.

“The ISDA 2020 IBOR Fallbacks Protocol, which incorporates the fallbacks into legacy non-cleared derivatives trades with other counterparties that choose to adhere to the protocol, remains open for adherence on the ISDA website.”
