This paper considers a rulemaking effort underway at the Securities and Exchange Commission to regulate the conflicts of interest that result when brokers send client orders to venues that pay the broker a fee in exchange for routing to them. These payments for order flow or rebates present a distortive conflict to a broker’s duty of best execution that has troubled the SEC for over 40 years and which the SEC has tried to regulate through multiple reforms. Courts have described the broker’s duties to their client as having a fiduciary character, which has long led some to question whether PFOF and exchange rebates violate that duty. The SEC’s new Chair has indicated he will more forcefully address broker conflicts. He has even suggested that an outright ban on PFOF and exchange rebates is “on the table”. Robinhood, a popular trading app that makes most of its equity trading revenue via payment for order flow, has threatened to challenge the rule in court.
Analysis of this rule, and of the likely outcome in subsequent court challenge, shows that Robinhood is likely to lose. The four top broker recipients of payment for order flow obtained $2.5 billion in PFOF in 2020, thus they have much at stake in this reform. The three dominant stock exchange families (particularly NYSE and NASDAQ) also have a stake in this rule, given that it is likely to prohibit similar broker inducements paid by stock exchanges. Supporters of the current system argue that zero commissions, popular among retail investors, are at risk if PFOF and exchange rebates are banned. While that may be true for some business models, this article notes that it is not true for business models like Fidelity that manage to provide zero commissions without accepting PFOF. This pending rule may well be the most substantial of Chair Gensler’s term and stands to bring more significant reform to the national market system than anything since the 1975 amendments to the Exchange Act that established the national market system. Yet this analysis is of interest not merely to brokers accepting PFOF and to the wholesale brokers and stock exchanges that pay them. This challenge also offers a deeper appreciation of the administrative law environment of SEC rulemaking in the market structure context.
