That marked an almost 11 per cent jump from a year earlier. About 50 per cent of the IDA lending went to Africa, followed by South Asia with a roughly 25 per cent share.
World Bank President Jim Yong Kim said the 188-nation Bank was on track in its mission to promote economic growth and shared prosperity and to fight extreme poverty in developing countries.
"The Bank's performance has been strong during my first year as president, and we are well positioned to address the economic challenges developing countries face during these still uncertain times," Kim said in the statement.
