Robert Zoellick will depart in June as president of the World Bank, once again raising the thorny issue of leadership of the Bretton Woods twins – the World Bank and the International Monetary Fund. At their birth, John Maynard Keynes memorably warned that if these institutions did not get good leaders they would “fall into an eternal slumber, never to waken or be heard of again in the courts and markets of Mankind.”

Getting a good leader, of course, requires a careful selection process. Today, however, the world is stuck with just the opposite: a dreadfully antiquated process whereby the United States and Europe, despite their economic travails, retain a monopoly on the leadership of the Bank and the IMF, respectively.

There is grudging agreement that this system should change. But the forces perpetuating the status quo – European and American resistance to change and emerging-market countries’ passivity – remain powerful, as the choice last year of Christine Lagarde to lead the IMF illustrated. Election-year politics in the U.S. will strengthen these forces further, with President Barack Obama’s administration unlikely to relinquish a symbol of global power, which would invite charges of weak leadership.

But, in some ways, the easy part is to state the case for the obvious: The World Bank requires a new selection process that will enable it to choose the most qualified person, regardless of nationality. The more difficult part is to identify the qualifications needed to run the Bank at a time when its role must be adapted to far-reaching global changes.

For the first time in a long time, a significant number of poor countries are catching up to the advanced economies, and the list of development successes is lengthening. That means that more of the poorest countries will therefore graduate out of the need for concessional lending from the World Bank.

The Bank’s nonconcessional lending agency, the International Bank for Reconstruction and Development, may well retain its rationale, especially because three-fourths of the world’s poor now reside in middle-income countries. But easier access to private finance will force a re-evaluation of the IBRD’s methods and the magnitude of its lending. For example, countries may want the World Bank to continue to provide neutral advice and set standards on procurement and quality, but without the high transactions costs that have become the hallmark of Bank finance.

At the same time, many of the development challenges in the foreseeable future – climate change, low agricultural productivity, growing water scarcity – are increasingly global in nature. Looking ahead, the World Bank will have to shift from lending to governments toward financing the provision of global public goods.

A more successful developing world also poses an intellectual challenge to the Bank as a custodian of research and policy thinking in the field of development economics. The World Bank, which has drawn predominantly upon U.S.-based centers of learning, can no longer ply a single model or dictate from a universal template. To be fair, the Bank has embraced the message of eclecticism, but a new leader will have to go further, paying greater attention to the specific contexts and demands of individual borrowers and learning from a wider set of successful development experiences.

The World Bank’s major shareholders also face a stark choice. If they believe that the Bank has a meaningful future worth supporting, it is the rapidly growing emerging-market countries, not the indebted West, that can provide the resources (this means China, of course, but even Brazil and India have growing aid programs). In return, they will rightly demand a greater voice in running the World Bank, especially if the Bank’s focus shifts towards global public goods.

But if the status quo powers are unwilling to cede control, the system of official international financing established by Bretton Woods will become increasingly fragmented. Countries like China will be reinforced in their belief that going it alone is the best option, with adverse consequences for multilateralism.

These dramatic shifts and daunting challenges mean that the World Bank’s next president will have to be someone whose primary task is to initiate and sustain change while commanding support and legitimacy across the Bank’s membership. He or she will also require a demonstrated capacity for political leadership and a core conviction that the Bank needs a new vision and path forward.

It is imperative that the selection process be altered to broaden the search for candidates who are sensitive to changing realities and possess key qualifications. This would not mean ruling out a deserving American candidate such as Hillary Clinton, but it would also mean looking carefully at others, such as former Presidents Luiz Inacio Lula da Silva of Brazil and Ernesto Zedillo of Mexico; Ngozi Okonjo-Iweala, the economics czarina in Nigeria; Mo Ibrahim, an exemplar of African business success; Nandan Nilekani, the Indian software mogul-turned-development-official; and Andrew Sheng of Malaysia, a distinguished former financial regulator.

The current selection procedure is losing legitimacy in a changing world, and it carries greater risks of a bad outcome: an unsuitable candidate. The consequences of retaining it might not be as dramatic as Keynes’ prophesied, but there is a real possibility that the World Bank will ossify into an institution whose increasingly impoverished G-7 donors dispense progressively smaller sums of money in the same questionable ways to a shrinking number of supplicants.
