In recent US Congressional testimony on oversight of depository institutions, Acting Comptroller Michael Hsu teased the prospect of collaboration by the OCC, Federal Reserve, and FDIC on crypto regulation. 

While a coordinated effort by these banking regulators would be preferable to an existing approach that Mr. Hsu described as "fragmented", it may yet take an even larger team-up involving the SEC and the CFTC to better shape the overall US federal regulatory landscape for digital assets.  

One can only hope for a sequel where state-level regulators join as well.
