The Securities Industry and Financial Markets Association is urging the U.S. Securities and Exchange Commission to implement a moratorium on market data rule filings for U.S. exchanges until the SEC is able to address the fundamental legal and policy issues created by for-profit exchanges.

SIFMA says it does not oppose market data fees per se, as exchanges should be able to recoup their costs and make a reasonable profit for providing this service. But, given the exchanges’ stranglehold on this data, SIFMA is advocating that prior to approving any new exchange market data fees, the SEC should comprehensively review the underlying cost data and competitiveness issues for all exchanges that provide market data (including NYSE, Nasdaq, AMEX).

As part of this review, SIFMA says, the SEC should conduct an economic and regulatory analysis to determine whether appropriate access to the product is available, and whether the proposed fee is fair and reasonable to firms, vendors and investors.

“The SEC cannot simply ignore the conflicts of interest inherent in today’s for-profit exchanges,” said Marc Lackritz, co-CEO of SIFMA. “The exchanges’ unique regulatory status allows them to profit from their market data without the threat of competition, but this conflicts with their congressional mandate to promote transparency.”

“This is a matter of investor protection. All investors and the professionals who serve them must have access to the same best quotes, based on the best information, to meet best execution obligations,” added Lackritz.

SIFMA says that the issue is perhaps best illustrated by NYSEArca’s “ArcaBook” market data product, which consists of “depth of book” market data that broker-dealers are legally required to provide NYSEArca. “Until now, NYSEArca redistributed this data back to the broker-dealer community and investors free of charge as a stimulus to generate liquidity and trading activity. NYSEArca recently filed a fee proposal with the SEC to begin charging for this data, but failed to provide any evidence that its proposed fees are fair or reasonable, as mandated by U.S. securities laws and regulations,” it says.
