The U.S. Office of the Comptroller of the Currency (OCC) doesn’t typically make crypto headlines – but when it does, it shakes the whole industry. That’s exactly what happened when the OCC issued Interpretive Letters 1170 and 1172, redefining how federally chartered banks can interact with digital assets.
Let’s break it down:
Banks Can Now Custody Crypto
Before these letters, the idea of a traditional bank holding your Bitcoin felt like mixing oil and water. But Interpretive Letter 1170 changed that.

Banks Can Use Stablecoins, Too
The second bombshell came with Interpretive Letter 1172, which clarified that banks can use public blockchains and stablecoins for payment activities.

What’s the Catch?

TL;DR
The OCC’s interpretive letters gave crypto the green light inside the traditional banking world. Custody and payments – once taboo topics – are now viable, regulated services for U.S. banks. It’s a quiet revolution that could finally bridge the old and new financial worlds.
