Two of Europe's largest clearing houses have clashed over the costs of moving euro-clearing into the European Union once the UK has left the bloc.

During a breakfast briefing on June 25, hosted by Financial News' trading and technology correspondent Sam Agini, senior executives from London Stock Exchange majority-owned LCH and Deutsche Börse's Eurex engaged in a heated discussion over the likely costs of relocating the clearing of euro-denominated swaps from London — where the bulk of the activity currently takes place —into the EU27.
