OCC Greenlights US Banks for Crypto Custody Services in Landmark Decision

In a groundbreaking move for the crypto industry, the Office of the Comptroller of the Currency (OCC) has issued Interpretive Letter #1184, confirming that US national banks and federal savings associations can now provide cryptocurrency custody and execution services on behalf of customers.

Announced on May 7, 2025, this decision marks a significant step toward mainstream adoption of digital assets, bridging traditional finance and the crypto ecosystem.

The OCC’s letter, which reaffirms and expands on Interpretive Letter #1170 from 2020, clarifies that banks may buy, sell, and hold crypto assets in custody, as well as engage in third-party risk management practices for crypto-asset activities.

It also acknowledges sub-custodians for crypto custody, allowing banks to offer services like facilitating cryptocurrency and fiat exchange transactions, transaction settlement, trade execution, recordkeeping, valuation, tax services, reporting, and more. As the OCC stated, “Providing crypto-asset custody services is a modern form of traditional bank custody activities.”

This regulatory clarity is expected to boost institutional participation in crypto markets. Banks can now custody assets directly or through sub-custodians, developing processes to ensure secure handling of digital assets on behalf of clients.

The move aligns with growing demand from institutional investors, with a 2024 Fidelity report noting that 74% of US institutional investors plan to allocate to crypto by 2026.

Industry leaders hailed the decision as a game-changer. “This is a pivotal moment for crypto adoption,” said Sarah Thompson, CEO of blockchain analytics firm Chainalysis, in a statement on X.

“Banks entering the space with regulatory backing will drive liquidity and trust.” However, the OCC emphasized that banks must implement robust risk management practices, reflecting the volatility and security challenges inherent in crypto markets.

For On-Chain Media readers, this development signals a new era of financial integration. With US banks now able to custody Bitcoin, Ethereum, and other assets, the line between TradFi and DeFi continues to blur.

Expect increased competition among banks to roll out crypto services—and potentially a surge in retail adoption as trusted institutions enter the fray.
