Coinbase Global (NASDAQ:COIN) Inc, the largest cryptocurrency exchange in the U.S, is reportedly calling on U.S banking regulators to revise or clarify their stance on banks offering custody and trading services for cryptocurrencies.

This move is aimed at making it easier for banks to partner with companies like Coinbase.

Coinbase has sent a letter to the Office of the Comptroller of the Currency (OCC), the Federal Reserve Board of Governors, and the Federal Deposit Insurance Corp. (FDIC), according to Bloomberg.

The letter, which was viewed by Bloomberg, appeals to the OCC to revoke an interpretive letter. Coinbase claims this letter establishes a de facto application process for new bank activities, which hinders banks from participating in the digital asset market.

In addition, Coinbase has requested the Federal Reserve and the FDIC to affirm that state-chartered banks under their jurisdiction can both offer and outsource custody and execution services related to cryptocurrencies, the report said.

Coinbase also retained three law firms that submitted a separate letter. This letter argues that current federal laws and regulations already permit banks to provide cryptocurrency services and engage with third-party service providers like Coinbase. Coinbase insists that banking regulators need to confirm this.
