Deutsche Börse warns 24/7 trading fragments liquidity, risks Germany 40 volatility

Deutsche Börse CEO Stephan Leithner reiterated warnings on April 27 via Reuters that 24/7 trading could fragment liquidity, increase volatility, and raise execution costs for indices like Germany 40 as Nasdaq gears up for extended hours. This builds on his April 24 comments opposing Wall Street's shift—Nasdaq filed in December for 23-hour weekday trading and CME launched 24/7 crypto futures—while many banks resist. Europe’s global equity trading share has dropped below 30% from ~55% two decades ago, prompting calls for regulatory consolidation.
