The International Monetary Fund on Monday named Jamaican Finance Minister Nigel Clarke to a top post at the agency, after the official spearheaded fiscal reforms in the Caribbean nation.

Clarke, nominated by IMF Managing Director Kristalina Georgieva, is set to replace Antoinette Sayeh as one of the IMF’s three deputy managing directors at the end of October.

Clarke had been key in negotiating credit lines with the IMF, starting in 2016 as ambassador of economic affairs before being appointed finance minister two years later.
