European competition authorities are ready to block the $9 billion (5 billion pounds) merger of NYSE Euronext
EU regulators met the exchanges at a meeting on Tuesday and discussed whether rivals and users felt that their proposals addressed competition concerns.
If the feedback is negative, it would be up to the companies to offer more substantial concessions or run the risk of the European Commission blocking the merger.
Le Monde said the authorities currently consider that the merger would lead to a duopoly on the European derivatives market and in the clearing business.
A person close to Deutsche Boerse said that it is premature to conclude anything has passed or failed in terms of regulatory approval.
Negotiations are ongoing, and we're still in the process of bluff and counterbluff, the source who is familiar with the company's thinking said.
A spokesman for Deutsche Boerse said the article was highly speculative and declined to comment. A spokeswoman for NYSE Euronext in Paris declined to comment.
Deutsche Boerse shares extended losses and were down 1.7 percent at 44.19 euros by 1:45 p.m. BT, slightly underperforming a 1 percent weaker STOXX Europe 600 Financial Services index <.SXFP>.
