Two of the barriers most often blamed for slow institutional crypto adoption have been removed: there is a regulated spot bitcoin product, and there is a fair-value accounting standard. The barriers that remain sit in bank capital rules, fiduciary duties and custody arrangements, and they limit how much an institution holds and in what form. This guide states each rule with its conditions as of October 20, 2026.
Key takeaways
- The SEC approved the listing of several spot bitcoin exchange-traded products on January 10, 2024, and approved generic listing standards for commodity-based trust shares, including those holding digital assets, on September 17, 2025.
- FASB ASU 2023-08 requires in-scope crypto assets to be measured at fair value with changes in net income, for fiscal years beginning after December 15, 2024.
- Under the Basel standard, a bank's Group 2b crypto exposure carries a 1,250% risk weight, so $10M of exposure needs about $10M of capital at an 8% ratio, against $0.8M for $10M of a 100% risk-weight loan. An asset that passes Basel's hedging recognition tests is Group 2a and gets a different, market-risk-based treatment.
- Basel also says total Group 2 exposure should generally stay at or below 1% of Tier 1 capital and must not pass 2%, which is $50M and $100M for a bank with $5B of Tier 1.
- In 2025 the OCC, FDIC and Federal Reserve withdrew earlier crypto guidance, and the Labor Department rescinded its 2022 warning on crypto in 401(k) plans, but fiduciary duties of prudence and loyalty did not change. A Labor Department safe-harbor rule proposed in March 2026 was still a proposal on October 20, 2026.
Barriers that fell
A regulated wrapper
On January 10, 2024, the SEC approved the listing and trading of a number of spot bitcoin exchange-traded products (ETPs). The SEC chair's statement was narrow. It covered products holding a single asset, which the SEC called a non-security commodity, and it did not endorse bitcoin, the products' custody arrangements or crypto trading platforms.
On September 17, 2025, the SEC approved generic listing standards for exchange-traded products that hold spot commodities, including digital assets. An exchange can now list commodity-based trust shares that meet those standards without first filing a rule change under Section 19(b) of the Exchange Act. The release does not set out the eligibility tests, so this article does not describe them.
Fair-value accounting
FASB issued ASU 2023-08 on December 13, 2023. According to a Deloitte summary of the standard, in-scope crypto assets are measured at fair value after initial recognition, with changes recognized in net income each period. The standard applies to all entities for fiscal years beginning after December 15, 2024, and early adoption was allowed.
Scope has conditions. An asset must meet the definition of an intangible asset, be fungible and secured by cryptography, sit on a blockchain or similar ledger, carry no enforceable claim on goods, services or other assets, and not be created or issued by the reporting entity or its related parties. Wrapped tokens and nonfungible tokens are generally outside it. Before the standard, entities other than investment companies and certain broker-dealers generally carried such assets at historical cost less impairment, which meant a rise in price did not show in earnings.
The Basel standard for banks
The Basel Committee on Banking Supervision published its standard on banks' cryptoasset exposures in December 2022. It now sits in the Basel Framework as chapter SCO60, with an effective date of January 1, 2026. Basel standards are not US law; they apply to a bank only as its national authorities implement them, and this article did not confirm the status of US implementation.
The 1,250% risk weight
The standard splits cryptoassets into groups. Under SCO60.6, Group 2 assets are those that fail the Group 1 classification conditions, which tokenised traditional assets and stabilised cryptoassets can meet. A Group 2 asset is classified as Group 2b unless the bank shows its supervisor that the asset meets the hedging recognition criteria for Group 2a (SCO60.54). For each Group 2b cryptoasset, SCO60.84 requires a risk weight of 1,250%, applied to the greater of the bank's aggregate long and aggregate short positions in that asset.
A risk weight scales an exposure into risk-weighted assets, and the bank's capital ratio is applied to that total. At 1,250%, every dollar of exposure becomes $12.50 of risk-weighted assets. At an 8% ratio, $12.50 × 8% equals $1.00 of capital per $1.00 of exposure, which is why the charge is described as dollar-for-dollar. SCO60.86 states the intent: minimum capital at least equal in value to the Group 2b exposure.
The Group 2a route
Group 2a status, under SCO60.55, requires all three of these tests to be met:
- Form of exposure: for example, a spot holding of an asset that has a regulated-exchange ETF or ETN, or a derivative cleared through a qualifying central counterparty, referencing only that asset; or an ETF or ETN on the asset that a markets regulator has explicitly approved for trading.
- Liquidity: average market capitalisation of at least $10 billion over the previous year, and a 10% trimmed mean of daily trading volume against major fiat currencies of at least $50 million.
- Data: at least 100 real price observations over the previous year, plus sufficient data on volumes and market capitalisation.
Group 2a exposures use modified versions of the market-risk approaches, which allow some recognition of hedging. Whether a given asset passes is for the bank to show its supervisor, so the 1,250% figure describes the default and the strictest case, not every crypto holding.
The Group 2 exposure limit
A separate limit applies to the size of the book, and it covers Group 2a and Group 2b alike. Under SCO60.116, it applies to direct holdings and to indirect ones, such as those held through investment funds, ETFs and ETNs. Under SCO60.117, a bank's total Group 2 exposure should not generally exceed 1% of Tier 1 capital and must not exceed 2%. Tier 1 capital is the bank's core loss-absorbing capital. SCO60.119 says exposure is measured the Group 2b way, using the higher of long and short positions in each asset.
Under SCO60.118, a breach of the 1% threshold should not generally occur, must be communicated to the supervisor immediately and must be rapidly rectified. Exposure above 1% gets Group 2b treatment until the bank is back in compliance. If exposure exceeds 2% of Tier 1, all Group 2 exposures receive Group 2b treatment.
The review under way
The Committee said in a February 25, 2026 release that, given recent cryptoasset market developments, it had expedited a review of targeted elements of the standard. After its September 28–29, 2026 meeting, an October 1, 2026 release said the Committee had advanced the review and expected to provide an update by the end of the year. Neither release says which elements are under review. No amended text had been published as of October 20, 2026, so the 1,250% weight and the 1% and 2% limits are described here as written in the current chapter.
Worked example: what a charge costs
Illustrative example. A bank holds $10M of a Group 2b cryptoasset and, separately, a $10M unrated corporate loan assumed to carry a 100% risk weight. Assume an 8% total capital ratio for both. The ratio is a round number for the arithmetic; actual requirements differ by bank and jurisdiction, and the loan's risk weight depends on the framework a bank uses.
Capital = Exposure × Risk weight × Capital ratio
Crypto: $10,000,000 × 12.50 × 8% = $10,000,000
Loan: $10,000,000 × 1.00 × 8% = $800,000
Exposure is the amount held, risk weight is the Basel multiplier (1,250% equals 12.50, 100% equals 1.00) and capital ratio is the share of risk-weighted assets the bank must back with capital. The crypto position needs 12.5 times as much capital as the loan, and its charge equals the full amount of the exposure.
| Item | Share of Tier 1 | Amount for a bank with $5B Tier 1 |
|---|---|---|
| General expectation: 1% of Tier 1 | 1% | $50,000,000 |
| Ceiling: 2% of Tier 1 | 2% | $100,000,000 |
| Capital at 1,250% and 8% on a $50M position | 1% | $50,000,000 |
| Capital at 1,250% and 8% on a $100M position | 2% | $100,000,000 |
The last two rows follow from the dollar-for-dollar charge: at that 8% ratio, a Group 2b position at the 1% limit requires minimum capital equal to 1% of the bank's Tier 1 amount. A higher required ratio would push the charge above the exposure. The table shows the arithmetic of the limits. It does not describe any bank's actual holdings, and a $10M position in this bank would be 0.2% of Tier 1.
The same $10M of capital would support $125M of 100% risk-weight loans at an 8% ratio ($10M ÷ 0.08).
US bank regulators in 2025
The US agencies removed procedural barriers in 2025. On March 7, the OCC issued Interpretive Letter 1183, which confirms that national banks and federal savings associations may engage in crypto-asset custody, certain stablecoin activities and participation in independent node verification networks. It also rescinds the requirement for OCC-supervised institutions to obtain supervisory nonobjection first.
On March 28, the FDIC issued FIL-7-2025, which rescinds FIL-16-2022 and lets FDIC-supervised institutions engage in permissible crypto-related activities without prior FDIC approval, provided they manage the risks. On April 24, the Federal Reserve Board rescinded its 2022 advance-notification letter (SR 22-6) and its 2023 nonobjection letter on dollar token activities (SR 23-8), and joined the withdrawal of two 2023 joint statements.
These actions concern permission and process. They do not change how much capital the Basel chapter would assign to a position, and none of the three releases addresses the risk weights above.
Fiduciary duties and 401(k)s
For retirement plans, the binding question is what a prudent fiduciary can justify. In 401(k) plans governed by ERISA, the Labor Department issued Compliance Assistance Release 2025-01 on May 28, 2025. It rescinded the March 2022 release that told fiduciaries to use "extreme care" before adding a cryptocurrency option. The Department said it takes no position for or against a fiduciary who concludes that crypto belongs on a plan menu, and that the analysis is context specific, resting on ERISA's prudence and exclusive-purpose requirements.
On August 7, 2025, Executive Order 14330 listed "holdings in actively managed investment vehicles that are investing in digital assets" among the alternative assets it addresses. It told the Secretary of Labor, within 180 days, to reexamine fiduciary guidance on offering asset allocation funds that include alternative assets, and to propose rules or guidance as appropriate, which may include safe harbors. An executive order directs agencies; it does not change ERISA.
The Labor Department followed with a proposed rule published on March 31, 2026. It would clarify the duty of prudence, and provide a safe harbor, for selecting designated investment alternatives in participant-directed plans, including asset allocation funds that hold alternative assets. Its preamble says there is no per se rule on actively managed vehicles that invest in digital assets. Comments closed on June 1, 2026, and as of October 20, 2026 no final rule had been published in the Federal Register, so the proposal does not bind plans.
The change moves crypto from a flagged risk to a decision a committee must document like any other, with a prudent process behind it.
Custody and the stablecoin statute
Custody is the operational barrier. The SEC's January 2024 statement said the approval did not endorse the products' custody arrangements. In the SAB 122 release, the SEC staff rescinded Topic 5.FF on January 23, 2025, so entities that safeguard crypto-assets for platform users now assess a loss liability under loss contingency standards (FASB ASC 450-20 or IAS 37) instead of the earlier special guidance.
For investment advisers and funds, the SEC proposed custody rules, published on October 6, 2026, that address how registered investment advisers may custody client crypto and how regulated funds may custody crypto securities. Comments are due December 7, 2026; until rules are adopted, the existing custody rules apply.
In New York, the Department of Financial Services issued updated custody guidance on September 30, 2025. It tells BitLicensees and limited purpose trust companies to segregate customer virtual currency from corporate assets and to obtain DFS approval before adding a sub-custodian.
The GENIUS Act (Public Law 119-27) became law on July 18, 2025 and takes effect on the earlier of 18 months after enactment, which is January 18, 2027, or 120 days after the primary federal payment stablecoin regulators issue final implementing regulations.
Frequently asked questions
Does the 1,250% risk weight apply to a bank's holdings of a bitcoin ETF?
It depends on the fund's classification. SCO60.83 applies the 1,250% treatment to funds of Group 2b cryptoassets, naming Group 2b cryptoasset ETFs, and to equity investments in them. Under SCO60.55, an ETF or ETN that a markets regulator has explicitly approved can qualify as Group 2a if the referenced asset also passes the liquidity and data tests. Either way, the holding counts toward the Group 2 exposure limit, which SCO60.116 extends to indirect holdings through funds, ETFs and ETNs.
Can a bank hedge a Group 2b position to cut the charge?
Not under the Group 2b treatment. SCO60.84 applies the 1,250% weight to the greater of the bank's aggregate long and aggregate short positions in each asset, so a bank long $10M and short $10M of the same Group 2b asset still carries $125M of risk-weighted assets. SCO60.86 adds that supervisors are to consider an additional capital charge where a bank has material short positions or crypto derivatives that could lose more than the 1,250% weight covers. Hedging is recognised only for Group 2a assets.
Did the 2025 US actions lower bank capital charges for crypto?
No release in this article addresses capital. The OCC, FDIC and Federal Reserve actions removed prior-notice and nonobjection steps and withdrew earlier guidance. The Basel risk weights are a separate matter, and the Basel Committee said on October 1, 2026 that it expected to give an update on its targeted review by the end of 2026.
Can an ERISA plan now add crypto to its menu?
The Labor Department's 2025 release says it neither endorses nor disapproves of fiduciaries who conclude crypto belongs on a menu, and that the decision should consider all relevant facts and circumstances. Duties of prudence and loyalty are unchanged, so adding crypto is permitted only if the fiduciary can support the decision under those standards. The safe harbor in the March 2026 proposal would apply only if the rule is finalized.
What changed when ASU 2023-08 took effect?
In-scope crypto assets are measured at fair value with changes in net income, and the balance sheet shows them separately from other intangibles. Adoption required a cumulative-effect adjustment to opening retained earnings, and prior periods were not restated.
Checklist for adoption news
- Identify the institution type: a bank (Basel capital and exposure limits), a retirement plan (ERISA duties) or a corporate treasury (fair-value earnings volatility).
- Check the form of exposure: direct holding, ETP shares or a fund, since Basel's limit counts indirect exposure, and for a bank, whether the asset is treated as Group 2a or Group 2b.
- Compare the size with the institution's capital base, using the 1% and 2% of Tier 1 limits as a yardstick for banks.
- Look for the date and the issuing body on any rule cited, and confirm it on the regulator's own page.
- Treat a headline about permission as separate from a headline about allocation size.
