Basel III proposal omits Bitcoin; 1,250% SCO60 risk weight exposes lender capital trade-offs

The latest confirmed developments

U.S. banking regulators released Basel III proposals on March 19, 2026 that did not mention Bitcoin or cryptocurrency, a gap industry commenters flagged after the rule was published. The Federal Reserve’s notice on March 19 lays out the proposal text and lacks explicit treatment of crypto assets. (See the Federal Reserve notice.)

In reaction, individual market participants submitted formal comments: Pierre Rochard filed written comments to U.S. banking regulators on March 29, 2026 regarding the Basel III capital framework and its treatment of crypto exposures.

How the rule could affect operations

Separately, the Basel Committee’s SCO60 crypto-asset framework assigns a 1,250% risk weight to unbacked crypto assets such as Bitcoin. That number is the core technical anchor for why domestic adoption of similar capital calibrations would change how banks price and provision for crypto custody and financing. (See the Basel Committee SCO60 framework.)

A 1,250% risk weight mechanically raises regulatory capital requirements for any bank with on-balance exposure to Bitcoin. In practice that means higher capital charges for custody businesses, larger capital cushions for lending desks that accept Bitcoin as collateral, and a direct hit to return-on-equity for unit economics built around low-margin custody and leverage products.

Where lender risk sits

The immediate lender-level effect is straightforward: applying a very high risk weight to unbacked crypto increases the capital a bank must hold against those positions. That, in turn, forces lenders to change pricing, reduce leverage, or limit product scope for Bitcoin-backed loans and custody services. Past regulatory guidance that did explicitly address tokenized securities shows regulators can and do give clear capital treatment when assets fit existing securities frameworks; the present gap on Bitcoin is what creates the ambiguity for lenders.

Where the signal really sits

Two things are clear from the record. First, the baseline Basel SCO60 treatment for unbacked crypto already exists and assigns a 1,250% risk weight — a hard reference point for U.S. rulewriters considering how to translate international guidance into domestic capital rules. Second, the March 19 U.S. proposals did not adopt or cite crypto-specific language; that omission leaves a policy choice open rather than resolving how Bitcoin exposures should be treated in the U.S. capital regime.

Assetify judgment: The juxtaposition of a domestic proposal that omits crypto and an existing international SCO60 standard with a 1,250% risk weight reveals the policy trade-off regulators face. If U.S. rulemaking imports a similarly high risk weight, Bitcoin lending and custody would require materially larger capital reserves, which would change loan economics and the availability of crypto-backed credit. That consequence matters for collateralized lending, counterparty exposure limits and the liquidity profile for Bitcoin in institutional markets.

If enacted, the practical change would be immediate: banks would need to reprice or withdraw certain Bitcoin-bearing products unless alternative mitigants or lower supervisory calibrations are specified in final U.S. rules.
