SEC scrutinizing fairness of stock exchange pricing system

The US Securities and Exchange Commission is investigating whether the multi-tiered pricing system used by stock exchanges favors large brokers at the expense of small ones, Reuters reports, citing a person familiar with the matter.

Under the current system, Wall Street banks and other massive traders get hefty rebates based on how much business they funnel to exchanges. The result of this complex and often opaque system is that big users can end up trading for free, or even get paid to trade, while small brokers pay substantial fees.

Most exchange operators, including New York Stock Exchange-owner Intercontinental Exchange Inc., Nasdaq Inc. and Cboe Global Markets, have embraced the system in at least some of their exchanges to help boost volumes and fatten their bottom lines.

While the SEC has not launched a formal civil investigation, it is seeking information from the exchanges on the pricing system. If the SEC were to determine that the tiered structure is unfair, exchanges could be forced to simplify their pricing models, potentially costing them millions of dollars in fees.

SEC spokeswoman Judith Burns declined to comment. NYSE and Nasdaq declined to comment on the SEC probe into multi-tiered pricing.

Cboe said it offers different types of pricing tiers catering to all of its clients and that the tiers are the result of years of intense competition among exchanges.

“At this point, we do not have plans to change our pricing schedules,” said Bryan Harkins, who co-heads Cboe’s markets division.

More generally, exchanges say that fierce competition in the industry has resulted in tighter bid-ask spreads that benefit all investors.

The regulatory scrutiny is part of a broader effort by the SEC under Chairman Jay Clayton to improve transparency around exchange pricing and ensure it is fair and equitable as required under the Exchange Act.

“The SEC has thrown the gauntlet down,” said Chester Spatt, a finance professor at Carnegie Mellon University and a former chief economist at SEC. Tiered pricing will likely emerge as a central issue in the debate, said Spatt, who has a working paper on the topic.

The regulator has also ordered exchanges to justify recent fee hikes for market data, and has mandated a pilot program to test banning rebate payments that exchanges make to brokers for liquidity-adding stock orders.

ICE, Nasdaq and Cboe have filed lawsuits or appeals challenging the SEC’s authority on those two mandates.

Tackling US exchanges is one of the few areas where Republicans and Democrats agree. Republicans believe the current rules are anti-competitive, while Democrats worry existing exchang structures and incentives could hurt small and large investors.
