The U.S. financial regulatory agencies recently announced plans to relax capital requirements for the nation's largest banks. This regulatory shift could free up billions of dollars in balance sheet capacity and lower the barriers for institutions to engage in digital assets, including cryptocurrency custody and trading.
Implications of the Proposed Capital Rule Changes
The proposals involve several federal banking agencies, including the Federal Reserve, the Office of the Comptroller of the Currency (OCC), and the Federal Deposit Insurance Corporation (FDIC). These agencies are collectively responsible for overseeing the capital adequacy standards of banks operating in the U.S.
Under the current rules derived from the Basel III international framework, large banks with total assets of $100 billion or more must maintain specific Common Equity Tier 1 (CET1) capital levels and comply with the Supplementary Leverage Ratio (SLR). These buffers are designed to ensure that banks can absorb losses during periods of financial stress.
Why Easing Capital Rules Could Boost Banks' Crypto Activities
For the crypto market, capital requirements directly limit banks' ability to hold or service digital assets. Under the Basel Committee's current framework, unsecured crypto assets are classified as Group 2b, with a risk weight of up to 1250%. This means that for every $1 of crypto assets held, banks must retain $12.50 in capital reserves.
This risk weight makes crypto custody and trading prohibitively expensive for most traditional banks, despite the growing demand from clients for institutional-grade digital asset services. Any reduction in overall capital buffers, whether through lowering the CET1 minimum or SLR exemptions, could free up banks' balance sheet capacity, allowing them to reallocate to higher-risk asset classes, including cryptocurrencies.
Several large banks have already expressed intentions to expand their digital asset businesses. BNY Mellon has launched crypto custody services, Goldman Sachs is exploring digital asset trading desks, and JPMorgan has built blockchain-based settlement infrastructure. Easing capital requirements will reduce the regulatory capital costs associated with these expansions.
A Broader Deregulatory Trend Reshaping Banks' Relationship with Cryptocurrency
This capital relief proposal is not an isolated occurrence. It is part of a broader deregulatory trend that has been gradually dismantling barriers between traditional banks and the crypto industry over the past year.
In January 2025, the OCC issued Interpretive Letter 1183, explicitly allowing national banks to engage in crypto asset custody and participate in blockchain networks without prior regulatory approval. The FDIC subsequently relaxed earlier regulatory guidance that discouraged banks from offering crypto-related services.
The Securities and Exchange Commission (SEC) has also contributed to this shift. The rescission of SAB 121's requirement, which mandated banks to list crypto custody assets as liabilities on their balance sheets, has eliminated a significant accounting barrier.
