Stock exchange operator IEX Group made waves this week when it released a report claiming that rival exchanges charge much more for market data compared to what it costs to produce.

This analysis estimated that in 2018, firms paid about 10 times to 30 times more than they had in 2010 to receive the same market information. This is partly owing to the proliferation of charges incurred for the same basic data, according to The Wall Street Journal.

The Nasdaq and New York Stock Exchange, competitors of IEX, in return pointed to the higher transaction fees associated with IEX in dismissing the findings of the report.

Either way, the report certainly reignited the debate about rising fees at the major stock exchange — something oft-complained about by institutional market participants.
