Europe increasingly more changing into a patchwork of auctions and off-exchange buying and selling, unearths file

With Eu law on darkish buying and selling starting to tighten, markets around the continent seem to be evolving clear of being an order book-dominated marketplace to a various panorama made up of auctions and off-exchange buying and selling.  

A contemporary file launched via the Affiliation for Monetary Markets in Europe (AFME) highlighted information from xyt which published that the lit order e-book best made up 27% of addressable buying and selling in This autumn 2025, with different mechanisms spanning auctions, systematic internalisers (SIs) and OTC transactions making up many of the remainder of the task. 

To provide an explanation for those findings, the find out about pointed against the EU’s transition from the double quantity cap (DVC) regime to the one quantity cap (SVC) for darkish buying and selling, as a part of an effort to simplify frameworks and strengthen transparency and consistency throughout Eu markets.  

Construction in this, the file published that early information has indicated that the shift has had an important have an effect on at the share of darkish buying and selling throughout Europe, with the choice of tools suspended on the EU degree beneath the SVC declining via 39% over a two-month duration – from 355 in October 2025, to 217 via the tip of December.  

In spite of this decline, displaced float does no longer seem to be shifting onto the substitute order e-book, however is as an alternative being routed to duration auctions, which noticed a marketplace proportion build up of one.3% following the SVC shift, indicating that institutional traders are prioritising decreasing knowledge leakage all the way through huge order execution.
