Request for Comment – Proposed Amendments to IIROC Rules and Form 1 – Floating Index Margin Rate Methodology – Investment Industry Regulatory Organization of Canada (IIROC)

Market Regulation Document Type
IIROC rule review

IIROC is publishing for public comment proposed amendments to the IIROC Rules and Form 1 (collectively, Proposed Amendments) regarding the floating index margin rate methodology (Methodology) applicable to qualifying Canadian and U.S. index products.

IIROC’s existing Methodology calculates lower than optimal margin rate requirements during long periods of low market volatility but results in sharp increases in margin rates during intermittent periods of high market volatility. The Proposed Amendments are required to reduce this procyclicality in the Methodology.

The Proposed Amendments:

  • introduce floor margin rates for qualifying Canadian and U.S. index products, and
  • codify current practices, including IIROC’s discretionary authority to limit sharp increases in floating index margin rates, if needed.

A copy of the IIROC Notice, including the Proposed Amendments, is also published on our website at The comment period ends on June 27, 2022.
