LONDON, Dec 3 (Reuters) – The gap between developing nations’ debt servicing costs and new financing hit a more than 50-year high of $741 billion between 2022 and 2024, the World Bank said on Wednesday, urging countries to use the more relaxed global financing conditions to bring their houses in order. In its annual International Debt Report, the Washington-based lender also found that overall interest payments had hit a fresh record of $415.
