Nasdaq, the US-based exchange group, said it has recruited Roland Chai, a senior exec from the Hong Kong stock exchange who also sat on the board of London’s LME Clear, as its new chief risk officer.

Chai, who was most recently head of HKEX’s post-trade division, overseeing clearing and risk management, will take up his new role on 1 June and will be based in Stockholm, where Nasdaq has substantial operations thanks to its ownership of Nordic stock-exchange operator OMX.
