I'm teaching cryptocurrency today in my Payment Systems class, and I'd been puzzling about why no one has applied the Electronic Fund Transfers Act and Reg E thereunder to crypto: after all, if you have a crypto account with an exchange, it would seem to be an "account" at a "financial institution" that is primarily for personal, family, or household purposes and is used for electronic transfers of "funds." In fact, I had just emailed Bob Lawless for a sanity check on this, when I came across a very recent SDNY decision that held that the EFTA applies to crypto. That's a huge consumer protection win. Reg E has important consumer protections regarding unauthorized transactions, error resolution, and provision of receipts and periodic statements. It also creates huge compliance headaches for crypto exchanges, which are not set up for dealing with any of those problems. All of the Zelle scam error resolution issues are now going to become crypto scam error resolution issues. And the ruling also indicates that consumer protection at cryptocurrency exchanges is now squarely within the existing regulatory authority of the Consumer Financial Protection Bureau. This could get interesting.
