Focus: Financial Law / MiFID License

The transition from MiFID II to the much-anticipated MiFID III (the 2026 MiFIR Review Amendments) represents the most significant overhaul of European capital markets in a decade. While MiFID II focused on unbundling research and increasing transparency, MiFID III is about efficiency and the centralization of data.

The Great Ban on “Payment for Order Flow” (PFOF)

The most seismic change in 2026 is the total EU-wide prohibition of Payment for Order Flow. For years, “zero-commission” brokers made money by selling their users’ trade orders to high-frequency market makers. Regulators argued this created a conflict of interest, as the broker was incentivized to send trades to whoever paid the most, rather than whoever provided the best price for the client.

In 2026, brokers must now adopt a pure fee-based or spread-based model. This has led to the “rebirth of the commission,” as retail platforms adjust their revenue streams. For licensed firms, the compliance burden has shifted to proving “Best Execution 2.0,” which requires microsecond-level data logs to justify why a specific trade venue was chosen.

Launching the “Consolidated Tape” (CT)

Market fragmentation has long been the “Achilles’ heel” of European trading. Unlike the U.S., which has a centralized feed for stock prices, Europe’s data was scattered across dozens of venues like Euronext, Deutsche Börse, and various dark pools.

The 2026 introduction of the Consolidated Tape Provider (CTP) changes the game. This central entity provides a real-time, “all-in-one” stream of trade data for equities and ETFs. For MiFID-licensed entities, this means:

1. Mandatory Data Contribution: Firms must pipe their trade data into the CT immediately.
2. Lower Data Costs: Small investment firms no longer have to pay exorbitant fees to multiple exchanges to see the “real” market price.

New Rules for “Dark Pools” and Systematic Internalisers

MiFID III further restricts “Dark Pool” trading. The “Double Volume Cap” (which limited how much trading could happen away from public exchanges) has been simplified into a single, stricter cap. This is designed to push more trading onto “Lit Venues” (public exchanges), ensuring that price discovery remains transparent and fair for all participants.
