Canadian Alternative Reference Rate Working Group

The Canadian Alternative Reference Rate Working Group (CARR) was created to identify and seek to develop a new term risk-free Canadian dollar interest rate benchmark. On this page, you can find more information about our mandate, market notices, publications, meetings, and membership.


Interest rate benchmarks are a cornerstone of the global financial system and are used by market participants across a wide range of financial products and contracts. In 2013, the Financial Stability Board (FSB) established the Official Sector Steering Group (OSSG) to advise the FSB on recommendations to strengthen existing interbank offered rate benchmarks (commonly known as IBORs), as well as to promote the development of alternative risk-free or nearly risk-free reference rates that could be used for some types of transactions. Both existing and new benchmarks would need to adhere to international regulatory standards, including the International Organization of Securities Commissions (IOSCO) Principles for Financial Benchmarks.

In response, Canada established the Canadian Alternative Reference Rate Working Group—sponsored by the Canadian Fixed-Income Forum—to identify and seek to develop a Canadian dollar term risk-free rate benchmark that is robust, reliable, and resilient to any market stress, as well as consistent with the IOSCO Principles for Financial Benchmarks and compliant with any applicable regulations. CARR will also explore possible enhancements to the existing Canadian overnight risk-free rate, the Canadian Overnight Repo Rate Average (CORRA).

ISDA IBOR Fallback Update

A guest speaker from ISDA provided an overview of ISDA’s consultation on final parameters for benchmark fallback adjustments. This consultation seeks input on the final parameters that will apply to RFRs if derivative fallbacks are triggered and interbank offered rate contracts convert to contracts referencing adjusted versions of the RFRs.

Enhanced CORRA Case Study

The Bank of Canada presented a case study on how CORRA would have behaved under the enhanced calculation methodology compared to the current methodology during abnormal market conditions seen on the 12 of June 2019 when CORRA set 14bps below the Bank of Canada’s target rate. Enhanced CORRA was found to have better-reflected overall market conditions because it represents a much larger volume of trades and trims the lowest 25% of trades, by repo rate.
