She will be taking over as many developing economies are facing severe stress, including a jump in poverty and capital outflows — as well as the plunge in commodity prices — because of the pandemic.
"The hit to emerging markets is just very broad. Nigeria is in terrible shape. South Africa is in terrible shape. Turkey is in terrible shape. Ecuador already is in default status, as well as Argentina. These are big emerging markets. It's going to be enormously costly," Ms Reinhart recently told Bloomberg Markets in an interview with Mr Rogoff.
Ms Reinhart also urged China to support debt relief for emerging markets, which is seen as critical given the flood of infrastructure loans supplied to developing economies through its Belt and Road Initiative in recent years.
"The largest official creditor by far is China. If China is not fully on board on granting debt relief, then the [G20] initiative is going to offer little or no relief. If the savings are just going to be used to repay debts to China, well, that would be a tragedy," she said.
David Malpass, the president of the World Bank, said Ms Reinhart's arrival would help "boost our efforts to restore growth and meet the urgent debt and recession crises" affecting many countries.
"Carmen has dedicated her career to understanding and surmounting financial crises in both advanced and developing economies in order to achieve growth and higher living standards," Mr Malpass said.
Ms Reinhart's research has also stoked controversy. Most notably, a 2010 paper co-authored with Mr Rogoff — which concluded that debt-to-GDP levels exceeding 90 per cent would impair growth — was attacked for containing spreadsheet errors and fuelling austerity policies in the wake of the crisis.
