Treasurer Jim Chalmers has lured a foreigner to become the Reserve Bank of Australia’s new deputy governor, appointing British central banker Andrew Hauser as second in charge at the central bank.

The appointment of an external candidate to fill the bank’s second-most senior role is the latest move by Dr Chalmers to overhaul the RBA, which is undergoing its most significant restructure in decades after the release of an independent review in April.
