The ripple effect of MiFID III on market data costs
Been pondering the potential impact of an eventual MiFID III revision, specifically around market data and reporting obligations. MiFID II certainly tightened things up, but I'm curious if anyone has been running scenarios on how further unbundling or even more granular reporting requirements could disproportionately affect smaller European brokerages or prop shops. The operational lift and associated data costs could become a real barrier to entry or scalability.
From a risk perspective, the increased complexity of managing various data vendors and ensuring compliance across all those streams is also something that keeps me up at night. Are there any clear signals out of Brussels or national regulators on their leanings for the next iteration?
