Olli Rehn, a former European Union top economic official, has been appointed Bank of Finland governor, the euro zone nation's central bank said today. 

During his years in Brussels as the EU's economic affairs commissioner between 2010 and 2014, Rehn became known as a low-key but hardline figurehead for austerity. 

He was hailed in several northern states as an enforcer of sound public finances, but loathed in the crisis-hit south as a driver of mass unemployment and recession. 

The 56-year-old Rehn, who holds a doctorate from Oxford University and loves playing football, has been the bank's deputy governor since 2017.

The governor's term in office is seven years.
