US Treasury Just Dropped a Big One for Stablecoins – July 2028 Deadline Is Real

Hey,

So the US Treasury dropped a Notice of Proposed Rulemaking yesterday (August 17) that hits right at the heart of how crypto exchanges deal with stablecoins for American users. Under the GENIUS Act, come July 18, 2028, platforms will generally have to stop selling or offering unapproved payment stablecoins to people in the US.

And they’re not messing around with the details. Advertising an unapproved stablecoin as available to Americans? Violation. Helping someone bypass IP checks or other location blocks so they can still buy it? Also a violation. Even responding to an unsolicited message from a US person by saying “yeah I can sell you some” counts.

This all comes from the GENIUS Act that President Trump signed back on July 18, 2025. It’s the big federal framework for payment stablecoins – the ones meant to stay stable and be used for actual payments. Issuers need to get licensed (federal or qualifying state) if they’re putting them out in the US, and platforms have this three-year runway before the hard stop on offering non-permitted ones to US persons.

The main effective date for a lot of the issuance rules is expected around January 18, 2027. But the big distribution cutoff for exchanges and other digital asset service providers is locked in for July 18, 2028 – three years after the law was signed.

Foreign issuers like Tether still have a possible path if their home country’s rules are judged “comparable,” they register properly, keep enough liquidity in the US, and can actually freeze coins when US authorities order it. But for regular USDT? A lot of people are watching closely to see if it makes the cut or if exchanges start pulling it for American customers well before the deadline. Tether already launched USAT through Anchorage as a more US-friendly version, so they’re clearly thinking about this.

The proposed rules are pretty broad on what counts as “offering or selling.” Direct soliciting, ads aimed at US buyers, guiding people around geoblocks, entering contracts – all of it. Platforms are going to need solid systems in place: real geolocation controls, no targeted marketing, and policies that actually work.

Public comments are open for about 60 days (roughly mid-to-late October). If you’re an exchange, issuer, or just care about how this plays out, that’s the window to speak up.

This feels like one of those regulatory moves that could quietly reshape liquidity and listings over the next couple years. Compliant, bank-linked or fully licensed dollar stablecoins will probably get a bigger push from institutions, while the pure offshore ones keep dominating global and DeFi volume. Two-tier market, maybe?
