The London Stock Exchange (LDNXF) agreed earlier this month to purchase economic information provider Refinitiv from a group of investors led by Blackstone (BX).

If completed, the deal would combine the information generated by the exchange with Refinitiv’s worldwide distribution and analytics.

It would also bolster the UK company’s position in foreign exchange and fixed earnings trading by way of Refinitiv’s FXall and Tradeweb platforms.

In February, an electronic trading method operated by CME Group (CME) was hit by a 3-hour outage triggered by a technical challenge.
