SEC plans to repeal trade-through rule, vote set for next week

The SEC is planning to vote next week on repealing the trade-through rule, a regulation that has long governed US equity market execution. This repeal could reshape market structure by increasing competition among trading venues and potentially opening pathways for tokenized securities to trade more efficiently across blockchain networks.

The SEC's proposed repeal of the trade-through rule represents a significant shift in regulatory approach to US equity markets. The trade-through rule, established under Regulation SHO, requires that brokers execute customer orders at the best available price across all registered exchanges. By removing this requirement, the SEC aims to foster greater competition and allow market participants more flexibility in order routing decisions.

This regulatory change emerges amid broader momentum toward modernizing financial market infrastructure. The fintech and blockchain sectors have long advocated for regulatory clarity on tokenized securities and distributed trading venues. The rule's repeal removes a structural barrier that could have hindered the integration of blockchain-based trading systems into the traditional equity market ecosystem. As central limit order books face pressure from alternative trading venues and technological innovation, relaxing this rule acknowledges shifting market dynamics.

For market participants, this change could reduce execution constraints and potentially lower trading costs through increased venue competition. Traditional market makers and retail investors may experience different execution quality depending on broker routing decisions. Blockchain projects developing tokenized securities platforms gain clearer regulatory pathways to operate within US markets, accelerating the digitalization of equity trading infrastructure.

The vote scheduled for next week will determine implementation timeline and any transitional provisions. Market observers should monitor whether the SEC proposes safeguards to prevent predatory routing practices, as removing best-execution mandates could incentivize brokers to route orders based on payments for order flow rather than customer benefit. The outcome will likely influence how quickly blockchain-based equity trading systems can achieve regulatory compliance.
