CFTC final rule replaces CDOR and TIIE clearing mandates with overnight risk-free rate requirements for CAD and MXN swaps

Executive Summary

The CFTC issued a final rule on September 2, 2026 amending its interest rate swap clearing requirement for Canadian dollar and Mexican peso instruments. The rule removes clearing mandates for CDOR- and TIIE-referenced swaps and replaces them with mandates tied to overnight risk-free rate benchmarks in both currencies.

Bottom Line

The rule redraws the mandatory clearing perimeter for two currency segments. CAD fixed-to-floating swaps referencing CDOR exit the clearing mandate; MXN fixed-to-floating swaps referencing TIIE exit as well. CORRA overnight index swaps now carry a 30-year maximum termination date under the mandate, and Overnight TIIE Funding Rate overnight index swaps enter the mandatory clearing schedule for the first time. Swap dealers, buy-side firms, and any counterparty with CAD or MXN interest rate swap exposure must audit current positions and booking practices against the amended instrument definitions before the rule's effective date.

Key Regulatory Signals

• CDOR Clearing Mandate Removed: Swap dealers and other covered entities are no longer required to submit Canadian dollar fixed-to-floating swaps referencing the Canadian Dollar Offered Rate for central clearing. Firms holding or booking such instruments must reassess their clearing workflows and documentation against the amended scope.
• TIIE Clearing Mandate Removed: Mexican peso fixed-to-floating swaps referencing the Interbank Equilibrium Interest Rate are removed from the mandatory clearing schedule. Counterparties that structured MXN exposure around TIIE-based cleared instruments face reclassification of those positions under the amended framework.
• CORRA OIS Termination Range Expanded: The Canadian Overnight Repo Rate Average overnight index swap class now carries a stated termination date range of seven days to 30 years, extending the mandatory clearing perimeter for CORRA-referenced instruments beyond the prior range.
• Overnight TIIE Funding Rate Added to Clearing Mandate: MXN-denominated overnight index swaps referencing the Overnight TIIE Funding Rate, with stated termination dates from 28 days to 21 years, are newly subject to the mandatory clearing requirement. Firms active in MXN interest rate markets must confirm that eligible instruments in this class are routed to a derivatives clearing organization or exempt DCO.
• Effective Date Tied to Federal Register Publication: The rule takes effect 30 days after Federal Register publication. Compliance timelines for clearing workflow changes, documentation updates, and DCO connectivity confirmations run from that publication date, not from the September 2 press release.

Regulatory Delta

- This rule extends the global benchmark reform transition that began with LIBOR cessation, applying the same overnight risk-free rate substitution logic to CAD and MXN clearing mandates that prior CFTC amendments applied to U.S. dollar and sterling mandates.

- The structural change is twofold: legacy benchmark clearing obligations are removed and new overnight rate mandates are added. This alters which instrument classes fall within scope for central clearing, rather than merely adjusting compliance dates.

- The Bank of Canada completed CDOR cessation in June 2024, and Banco de México has advanced the Overnight TIIE Funding Rate as TIIE's successor. This CFTC action aligns with those central bank benchmark transitions.

Materiality Classification

HIGH — Final rule with an effective date 30 days after Federal Register publication; the amended clearing mandate falls on all swap dealers and covered counterparties active in CAD or MXN interest rate swap markets, requiring immediate audit of in-scope instrument classifications and DCO routing procedures.

Intelligence Outlook

Monitor the Federal Register for publication of this final rule to confirm the precise effective date and any associated compliance date amendments under this rulemaking.
