[!info] TL;DR The BCBS (Basel Committee on Banking Supervision) published the “Prudential treatment of cryptoasset exposures” standard (SCO60) in 2022-12 , classifying cryptoassets into 2 groups: Group 1 (compliant tokenized assets or qualifying stablecoins) applies existing risk weights of 5-100%; Group 2 (other cryptoassets including BTC/ETH) applies a 1,250% risk weight + 1% exposure limit. 2025-01-01 was set as the target implementation date for jurisdictions.

Key facts

  • BCBS SCO60 published: 2022-12-16
  • Global implementation target date: 2025-01-01
  • Group 2 exposure limit: 1% of Tier 1 capital
  • Treatment when limit exceeded: amount above limit receives 1,250% × 2 = effective 2,500% risk weight
  • EU / HK / JP / SG / CH: full implementation 2025-01 through 2025-04
  • UK: implementation 2026-01-01
  • USA: 2025-07 delayed to 2026-07 · delayed due to banking industry lobbying

Mechanism / How it works

BCBS SCO60 4 -group classification:

  • Group 1a (Tokenized TradFi): tokenized bonds/equities/commodities · same RW as underlying (5-100%) · examples: BUIDL / OUSG / ONDO · redeemability + legal enforceability required
  • Group 1b (Qualifying SC): fully reserved + real-time redemption · must pass redemption risk + basis risk (≤10bp for 99% of the time) tests · candidates: USDC PPSI / EURC / USDB · disqualified: DAI / FRAX / USDT
  • Group 2a (Hedged): BTC/ETH hedged with derivatives · 1,250% RW + capital relief
  • Group 2b (Other): 1,250% RW = 100% capital backing · 1% exposure limit

Basel III formula: RWA = Exposure × Risk Weight × 12.5 · Capital = RWA × 8%. $100 BTC exposure → RWA = $100 × 1250% = $1,250 → Capital = $100, i.e. 1:1 capital deduction. Practical effect = banks must maintain 1:1 capital against BTC positions, degrading ROE relative to normal credit by ~12.5x. Comparison with USDC Group 1b: reserve = short-term treasuries + cash · applicable short-term treasury risk weight 0-20% · capital ~10%, far less costly. HK’s reserve framework connects directly to SCO60 ; see HK FRTB Stablecoin Reserve Requirements · HKMA Reserve Framework for details.

Origin & evolution

BCBS launched cryptoasset consultation in 2019 年, introducing the Group 1/2 classification prototype in the 2 th round CP of 2021 年. Final CPs issued 2022-06 ; SCO60 standard published 2022-12-16. Jurisdictions completed domestic BCBS implementation proposals in the first half of 2024 年, setting 2025-01 as the global implementation target. In the US Endgame proposal, megabank lobbying sought partial exemptions for BTC/ETH ETFs; Trump 2.0 leans toward a light-touch approach, with 1,250% possibly softened to ~150-300% in the 2026-Q3 final rule.
