What happened
Today, 1 January 2026, is the date the Basel Committee's cryptoasset standard takes effect. It is the second such date. The Committee published the standard in December 2022 as chapter SCO60, to apply from 1 January 2025. On 13 May 2024 the Group of Central Bank Governors and Heads of Supervision, the Committee's oversight body, agreed "to defer implementation of the Committee's prudential standard for banks' cryptoasset exposures by one year to 1 January 2026".
The extra year produced targeted amendments on 17 July 2024. The taxonomy did not move: Group 1a tokenised traditional assets, Group 1b stablecoins meeting the stabilisation criteria, Group 2a exposures that pass the hedging recognition criteria, Group 2b everything else. What moved was narrower. Short-term reverse repo receivables became eligible Group 1b reserve assets. Bankruptcy-remoteness of reserves was tightened, with a carve-out where a bank only provides custody. A proposed basis-risk test was dropped as a classification condition and pushed into bank due diligence, with supervisors able to override a classification. The haircut on Group 1b, 2a and 2b assets lent or posted in securities financing transactions became a flat 30 percent. The same day the Committee published Disclosure of cryptoasset exposures, chapter DIS55, which applies from 1 January 2026 as well.
What it changes
For any bank, today, nothing. The Committee's own Charter says so in section 3: "The BCBS does not possess any formal supranational authority. Its decisions do not have legal force. Rather, the BCBS relies on its members' commitments."
A Basel standard is a template plus a coordination date, and the date is the only enforcement it has, because the point of agreeing one is to stop any single jurisdiction moving first and disadvantaging its own banks. A deferral is therefore not a favour to banks. It is a repair to the coordination point: a standard half the membership implements is worse than none, since it relocates the activity rather than capitalising it.
What it does not change
No capital treatment moved. Total Group 2 exposure "should not generally be higher than 1% of the bank's Tier 1 capital and must not exceed 2%". The 1 percent is a soft trigger: breach it and the excess falls into Group 2b treatment. The 2 percent is the hard limit: breach it and the whole Group 2 book does. The 1250 percent risk weight applies to Group 2b only, and to the greater of the absolute value of aggregate long and of aggregate short positions in each cryptoasset. It is not a blanket weight on cryptoassets.
One thing coverage almost never says: a 1250 percent weight produces capital equal to the exposure only against the 8 percent minimum ratio. Buffers sit on top, so the real requirement is more than one for one.
It did not slow the jurisdictions that had already legislated, and it touches nobody outside a prudentially regulated bank. Not an exchange, not a fund, not a person holding coins. It says nothing about whether anyone may own bitcoin.
Context
The EU did not wait, and did not implement this standard either. Regulation (EU) 2024/1623, CRR3, in force since 9 July 2024, carries Article 501d, "Transitional provisions on the prudential treatment of crypto-assets". It is a simplified stand-in: tokenised traditional assets treated as the underlying, MiCA-compliant asset-referenced tokens at 250 percent, everything else at 1250 percent, and exposure to that last category capped at 1 percent of Tier 1 capital. That 1 percent is not the Basel 1 percent: it attaches to a different, MiCA-shaped set of exposures, and the two get conflated constantly. The article also obliges the Commission to propose a Basel-aligned regime by 30 June 2025, and the European Banking Authority published final draft technical standards under Article 501d(5) on 5 August 2025.
That is the second half of the mechanism. When the international date slips, a jurisdiction that has already legislated does not wait. It enacts a crude placeholder, Basel-shaped but not Basel, and the placeholder becomes the binding rule for years. Elsewhere less happened still: the United Kingdom has neither implemented the standard nor consulted on it.
And the date arrives with the text already reopened. On 19 November 2025 the Committee agreed to expedite a review of targeted elements of the standard.
What a bank obeys is never the Basel text. It is whatever its own supervisor has written down, which is usually a simplification of an older draft.
