Canada’s banking regulator has finalized a narrow change to its crypto capital rules that should reduce capital overstatement for some market-neutral positions without broadly easing how banks must treat digital-asset risk.
The Office of the Superintendent of Financial Institutions’ 2027 guideline, published Sept. 10, treats all regulated exchanges of traditional financial assets as one exchange when banks calculate delta risk for qualifying Group 2a crypto exposures. That allows positions in the same crypto asset on different qualifying regulated exchanges to receive full capital recognition when they also have the same time to maturity.
What changes, and what does not
The change addresses a specific mismatch between trading practice and capital calculations. In its May consultation backgrounder, OSFI said banks primarily use market-neutral strategies for crypto exposures and that prices for the same asset tend to move almost identically across major regulated exchanges. Treating each venue separately could therefore make the calculated risk, and the capital held against it, larger than the underlying position warranted.
The final treatment does not create unconditional offsetting. It applies only to Group 2a exposures that satisfy the guideline’s hedging-recognition tests, including product structure, regulatory approval or qualifying clearing, liquidity and data-history conditions. Positions associated with unregulated exchanges do not gain the same cross-exchange recognition, and differences in time to maturity still matter.
In plain terms, Group 2a contains crypto exposures that qualify for limited hedging recognition, while Group 2b covers the Group 2 exposures that do not. The framework retains a 94% correlation parameter for calculating delta or vega capital within a Group 2a bucket. Delta and vega risk weights remain 100%, and banks cannot recognize diversification across different Group 2a crypto assets.
Group 2b treatment is substantially stricter. For each Group 2b asset, a bank must deduct from common equity tier 1 capital the greater of its absolute aggregate long or short position. If the prescribed market-risk and credit-valuation-adjustment calculation produces a higher requirement, the bank must use that higher amount.
OSFI also kept Canada’s aggregate gross exposure limit for Group 2 crypto assets at 5% of Net Tier 1 capital, with an exclusion for certain client-clearing derivatives. A breach makes all of the institution’s Group 2 exposures subject to the Group 2b treatment.
The result is targeted relief rather than a broad capital easing. Banks can remove an exchange-specific penalty for a tightly matched hedge that meets the rule’s conditions, but they still face high risk weights, conservative treatment for non-qualifying assets and a firm exposure ceiling.
The guideline takes effect Nov. 1, 2026, for institutions with an Oct. 31 fiscal year-end and Jan. 1, 2027, for institutions with a Dec. 31 fiscal year-end. The effective dates match those laid out when OSFI opened consultation in May.
