‘Exchanges owe us answers’ says IEX as it discloses market data and connectivity costs


Investors Exchange (IEX) has publicly disclosed its costs of producing market data and connectivity, suggesting that incumbent exchanges could be marking up charges for such services by as much as 4,000%.

Through a detailed review of the costs for IEX to provide depth of book market data, physical connectivity and logical connectivity, co-founder and CEO Brad Katsuyama said in a statement that “exchanges owe us all some answers”. 

IEX concluded in its review that for depth of book data products, incumbent exchange operators including NYSE, Nasdaq and Cboe, are charging fees that are between 900-1,800% more than IEX’s costs to offer the same product. In addition, for physical connectivity in data centres, IEX said incumbent exchanges charge fees that are between 2,000-4,000% more than IEX’s costs to provide the same connectivity. The TRADE is awaiting comment from the exchanges mentioned in IEX’s report.

The bold move by IEX makes it the first US exchange operator to publicly disclose its costs of producing market data and connectivity to investors, which Katsuyama has described in the past as being “almost complete cloaked in darkness”. 

“The costs IEX incurs to offer these products and services include the same basic costs incurred by other exchanges,” Katsuyama said about IEX’s report. “The potential profit margins that are implied by our study, on their face, contradict the claims by the major exchanges that the fees they charge the industry for their market data and connectivity are fair, reasonable, and competitive.”

The battle over exchange market data costs and connectivity came to a head in October, after the US financial regulator hosted a roundtable discussion with industry heavyweights on the issue. Broker-dealers, trading firms and IEX, heatedly argued the fees that exchanges charge for depth of book data, as well as SIP data, are grossly overpriced considering how little they supposedly cost to produce.

Major Wall Street firms, alongside IEX, have urged the Securities and Exchange Commission (SEC) to examine the fees in terms of revenues and costs, but incumbent exchange groups countered that for full transparency, every firm must reveal their operational costs. 

Against this backdrop, a band of institutions in the US announced plans earlier this month to launch MEMX, or Members Exchange. MEMX aims to reduce fixed costs of trading with a low-cost fee structure, a move that some in the industry suggested could be a ploy to bring the issue of costs to the incumbent exchanges.

“All exchanges, including IEX, have a distinctive responsibility to help maintain a healthy capital markets ecosystem and must be held to a higher standard than any other participant. With this unique regulatory position comes the responsibility to prove that the prices they charge their members are fair, reasonable, and promote rather than undermine competition. The exchanges owe us all some answers,” Katsuyama concluded.
