Canada’s New Crypto Rules Change the Math for Banks

Key Takeaways

• Rules start November 1 for Canada’s big banks.
• Matched crypto hedges now offset across exchanges.
• Client clearing no longer counts toward the cap.
• The 5% cap and collateral limits stay.

OSFI finalized the revisions in September, and its implementation letter sets November 1, 2026 as the start for institutions with October 31 year-ends, which include Canada’s six largest banks. Banks with December 31 year-ends follow on January 1, 2027, despite the guideline’s 2027 label.

Two limits, two different jobs

Banks face two separate constraints on crypto. Capital is the cushion held against losses on a position. The Group 2 exposure limit caps how much measured crypto exposure a bank can carry, at 5% of its Net Tier 1 capital. Go over it, and all Group 2 exposure falls into the harshest Group 2b treatment. Under the Basel standard OSFI follows, that means a 1,250% risk weight, roughly capital equal to the full exposure.

The new rules ease each constraint in a different place. Hedges get relief on capital, and client clearing gets relief on the cap. Two examples, using hypothetical numbers rather than any bank’s actual figures, show how.

Hedges: the offset counts for capital, not for the cap

The hedge change covers Group 2a, crypto exposures that meet OSFI’s conditions for hedge recognition. For the relevant price-risk calculation, regulated exchanges of traditional financial assets are now treated as a single exchange. Matching long and short positions in the same crypto-asset with the same maturity can be fully offset, even when they sit on different venues.

Take a bank with C$10 million of long Bitcoin futures on one qualifying exchange and C$10 million short on another, both measured on a delta-equivalent basis, which adjusts derivatives for how much they move with the underlying price. The contracts meet the Group 2a tests and match on terms.

For capital against price risk, the two positions now cancel. Counterparty, basis and other risks still need to be assessed separately.

For the exposure cap, the position still counts as C$10 million, not zero. OSFI measures each crypto-asset by the larger of the absolute long or short total, so equal positions do not net out. Its crypto-asset FAQ keeps the two measures explicitly separate. A perfectly hedged book can still use up room under the cap.

Client clearing: room under the cap, not cheaper capital

The clearing change excludes qualifying derivatives client-clearing exposures from the Group 2 limit. It applies when a bank stands between a client and a qualifying central counterparty, or QCCP, not to every service a crypto client uses. In its consultation responses, OSFI says the industry asked for relief from both the cap and the capital requirements; it granted the first and refused the second.

Take a bank with C$1 billion in Net Tier 1 capital. Its 5% cap allows C$50 million of Group 2 exposure. If qualifying clearing trades would have counted for C$20 million of that, excluding them frees C$20 million of room, 40% of the whole allowance. That is capacity, not savings. The bank still holds capital against the clearing business; it simply has more space under the cap for everything else.

Built for intermediaries, not bigger bets

The design favours banks that sit in the middle of client trades and run matched books, rather than banks taking directional positions in crypto. Whether that shows up in practice depends on eligibility. Even as regulated crypto futures markets expand, each product still has to pass the Group 2a tests, and positions in different coins, different maturities or instruments that move differently cannot be offset as if they were identical.

Nor is this the moment banks were first allowed into crypto. OSFI’s September backgrounder says the earlier framework did not stop them; the new rules change how specific activities are treated.

What stays the same

The 5% of Net Tier 1 ceiling itself is not new; OSFI set it in an October 2025 letter, and the final guideline keeps the Group 2b penalty for breaching it. Group 2 assets still cannot count as high-quality liquid assets for liquidity rules.

Lending against crypto gets no relief either. OSFI declined to recognize Group 2a crypto-assets as eligible collateral for capital purposes, citing enforceability, liquidity and volatility under stress, so better treatment for a Bitcoin hedge does not carry over to a loan backed by Bitcoin. Tokenized bank deposits sit under a separate analysis, as Coindoo explained in its look at Canada’s tokenized-deposit rules.

The first quarter under the new treatment runs from November through January. The big banks’ fiscal first-quarter results, usually published in late February, will be the first that could show whether the extra room is being used for clearing and hedging, and whether any of it reaches client pricing.
