CRS Reviews Policy Debate Over Payment for Order Flow

The Congressional Research Service ("CRS") reviewed the policy debates over rebates that retail brokerage firms receive for directing retail investor stock trades to certain venues, known as "payment for order flow" ("PFOF").

In an In Focus Report, the CRS described the regulatory framework for broker-dealers and outlined the rules involving PFOF. CRS highlighted:

• Best Execution. Brokerages must (i) evaluate the orders from all customers and periodically determine which competing markets and market intermediaries offer the most favorable terms, (ii) consider price improvements and (iii) consider the trade-off between price improvements and the extra time it takes to seek better pricing.
• Disclosure and Transparency. Under Regulation NMS Rule 606(a) ("Disclosure of order routing information."), broker-dealers must provide quarterly, aggregated public disclosure of their practices in the routing and handling of "held orders" that required prompt execution at the best possible price. Under Regulation NMS Rule 606(b) ("Disclosure of order routing information."), upon a customer’s request, a broker-dealer must provide customer-specific disclosures related to the routing and execution of the customer’s exchange-listed securities submitted on a "not held" basis which gave the broker-dealer both time and price discretion during the prior six months. Under Regulation NMS Rule 607 ("Customer account statements."), a broker-dealer must, upon opening a new customer’s account, provide annual descriptions of the terms of any payments received for order flow and any profit-sharing arrangements that may influence a broker-dealer’s order routing decision.

The CRS detailed the following policy debates:

• Market concentration and competition. Opponents of PFOF argue that the market is opaque and not as fair and competitive as it could be for retail investors.
• Zero-commission trading and retail investor inclusion. Supporters of PFOF argue that the practice benefits investors by subsidizing low- or zero-commission rates and other services, allowing more people to invest their savings in stocks.
• Investor protection offered through best execution requirements. Proponents argue that existing best execution laws ensure that brokerage firms prioritize client interests and secure favorable trade outcomes for orders, regardless of PFOF. Opponents argue that broker-dealers may not pass PFOF rebates on to their clients, but rather to market makers that benefit the broker-dealer most.
