Basel Committee held its line on permissionless crypto risk

The Basel Committee on Banking Supervision said on December 7, 2023 that it would retain the existing prudential treatment for cryptoassets using permissionless blockchains after concluding that their risks could not be sufficiently mitigated at that time. The global banking standard-setter also agreed to consult on targeted revisions to the criteria determining whether stablecoins qualify for preferential “Group 1b” treatment.

The decision mattered because it addressed how internationally active banks could obtain exposure to public crypto infrastructure—not whether individuals could hold or transact in cryptoassets. By declining to ease its approach to permissionless networks, the Committee preserved a substantial regulatory distinction between digital assets capable of meeting its lower-risk classification conditions and those remaining under the framework’s more conservative treatment.

The line between Group 1 and Group 2

The Committee’s underlying cryptoasset standard, issued on December 16, 2022, divided bank exposures into two broad groups. Group 1 included tokenized traditional assets and stablecoins satisfying the complete set of classification conditions. Group 1b specifically covered cryptoassets with effective stabilization mechanisms.

Qualifying stablecoins had to meet conditions addressing redemption, reserve sufficiency and supervision. The Committee’s May 31, 2023 summary said Group 1b was available only to stablecoins issued by supervised and regulated entities. Stablecoins failing any Group 1 condition joined unbacked cryptoassets in Group 2, where the framework applied more conservative capital treatment.

On December 7, the Committee did not announce that a particular stablecoin had qualified or failed. It agreed to review the criteria governing access to Group 1b and said a consultation would be published during December 2023. The announcement supplied no proposed reserve composition, statistical test or final amendment that could properly be attributed to the December 7 record.

Permissionless networks remained the dividing issue

The Committee said permissionless blockchains generated risks that banks could not sufficiently mitigate at that point. Its announcement did not enumerate those risks, but the conclusion meant supervisors were unwilling to relax the existing framework merely because regulated institutions might apply controls around their own participation.

That distinction had implications beyond unbacked cryptocurrencies. Banks and traditional financial firms were exploring tokenized securities, settlement assets and custody services using distributed ledgers. If an asset’s underlying infrastructure prevented it from satisfying the classification conditions, placing a regulated institution around the transaction would not by itself secure preferential treatment.

The Committee separately reviewed operational risks arising when banks provide cryptoasset custody. It called for full implementation of its existing operational-resilience and operational-risk principles and said it would continue monitoring custody activity. That was a supervisory warning, not a new custody prohibition or a finding that a named bank had breached a rule.

A standard-setting decision, not a direct ban

The Basel Committee described itself as the primary global standard-setter for prudential bank regulation, but it also emphasized that it has no supranational authority and that its decisions have no direct legal force. Member jurisdictions implement Basel standards through their own regulatory systems.

The December 7 decision therefore did not ban permissionless blockchains, regulate crypto exchanges or impose requirements directly on token holders. Its practical force lay in the incentives facing internationally active banks: regulatory capital and supervisory treatment can affect whether providing exposure, custody or tokenization services is commercially viable.

The December 2022 standard was expected, as of December 7, 2023, to be implemented by January 1, 2025. That was the contemporaneous timetable, not evidence that every member jurisdiction had enacted matching rules.

Later documentary context

On December 14, 2023, the Committee published the promised consultation with proposed stablecoin-reserve and due-diligence amendments. That later document clarified the contemplated changes but does not alter what was established on December 7: the Committee had decided to consult while retaining its existing approach to permissionless-blockchain risk.
