The SEC moved to kill Rule 611, the 2005 rule that kept tokenized stocks offshore.
This is primarilt market structure story, but tokenization is noteworthy side effect.
Rule 611, the "trade-through" rule, made the national best bid and offer the legal default for US stock trade. (I.e.if there's a best price somewhere, its had to be honored)
It's also why on-chain equities couldn't trade onshore. An on-chain venue can't respect an order price that only lives on registered exchanges in market hours. They're non-compliant by default, or bolted onto the plumbing it was built to escape.
Strip out 611 and best execution falls back to FINRA Rule 5310, a broker-level duty rather than a routing mandate. A broker can meet a duty by routing to an on-chain venue.
Nearly all the tokenized equity trading today sits offshore. xStocks issues out of Jersey and Bermuda. Robinhood launched in the EU.
The on shore incumbents don't want to be caught flat footed. NASDAQ has approval to tokenize, NYSE is building a venue, DTCC starts tokenized trades in July.
611 existed because retail used to get filled at worse prices than were on offer.
With that rule gone, do we get something to replace it or does the consumer lose out?
