Discussions on reforming the World Bank have typically centered on
   making the most of existing resources — U.S. Treasury Secretary Janet
   Yellen’s squeeze-the-lemon approach — and enticing more private sector
   investment, an even more obvious approach now that former Mastercard
   CEO Ajay Banga is in charge of the bank.
   But there’s one question looming quietly but large in the wings:
   Whether to give the bank more money, i.e., a capital increase. Many
   experts say wealthy shareholders will have to put up more if they want
   to stare down the twin challenges of poverty and climate change, but so
   far talk has focused on billions of additional dollars.
   Now, apparently, we’re talking trillions.
   Nine experts, including former U.S. Treasury Secretary Lawrence
   Summers, were tasked by the Indian presidency of the Group of 20
   leading economies to outline a road map for reforming institutions such
   as the World Bank.
   In a lengthy report obtained by my colleagues Vince Chadwick and
   Shabtai, the experts say that achieving the bank’s proposed “triple
   mandate” — eliminating extreme poverty, increasing shared prosperity,
   and boosting global public goods such as climate and pandemic
   prevention — will require an additional $3 trillion in available
   capital per year by 2030.
   The experts’ report, which backs the ongoing reform efforts, also says
   multilateral development banks have to get better at drumming up
   private capital. “Today, MDBs only mobilise 0.6 dollars in private
   capital for each dollar they lend on their own account,” the G20
   authors write. “They should aim to at least double this target.”
