According to @AltcoinDaily, a new U.S. Office of the Comptroller of the Currency (OCC) letter states that U.S. banks are officially allowed to buy and sell Bitcoin (BTC), Ethereum (ETH), and other cryptocurrencies for customers.

Traders should locate and review the OCC letter on the OCC’s official site to confirm the exact scope of permissions (e.g., brokerage execution vs. agency services), eligible customer segments (retail vs. institutional), any supervisory non-objection requirements, and the effective date before positioning.

For context, the OCC previously clarified in 2020 that national banks may provide cryptocurrency custody services, showing the agency uses interpretive letters to define permissible bank crypto activities that can influence market access.

Until the OCC document is reviewed, monitor official OCC publications and U.S. bank disclosures for confirmation and operational timelines that could affect fiat on-ramps and trading flows across BTC and ETH markets.
