Borse Dubai, the holding company representing the two largest Dubai exchanges, has borrowed $5.8bn (€4.05bn) from a group of six banks to bankroll its purchase of OMX, the Nordic exchange operator, and a substantial stake in the London Stock Exchange.

The exchange group, which plans to buy OMX and flip it on to Nasdaq in return for the majority of the US exchange's stake in the LSE, has funded its purchases in two one-year deals valued at $4.2bn and $1.6bn, according to Bloomberg.
