Multilateral development banks (MDBs) have become the darling of policy-makers nowadays. In a recent speech, US Treasury Secretary Janet Yellen called on the World Bank and other international lenders to support developing countries struggling with the effects of rising inflation and aggressive interest rate hikes. And a recent independent report commissioned by the G20 concludes that these institutions are uniquely positioned to help governments achieve the United Nations’ Sustainable Development Goals.

The G20 report argues that MDBs could expand their lending without hurting their AAA credit ratings, were it not for excessive capital adequacy requirements that limit lenders’ ability to take risks. But which countries would benefit the most from an increase in multilateral financing? While multilateral development banks play a critical role by providing long-term loans at concessional interest rates to low-income countries (LICs), the overwhelming majority of their financing goes to middle-income countries (MICs).

A recent OECD report finds that 70% of MDB loans went to MICs in 2020, following a large increase in lending to lower-middle-income countries (LMICs).

In other words, the problem is one of allocation, not volume.

Clearly, MDBs must significantly increase their lending to developing countries struggling with extreme poverty and limited institutional capacity. Unlike MICs, most LICs have little to no access to capital markets and are in dire need of financing, owing to the disproportionate effects on their economies of the Covid-19 pandemic, the war in Ukraine and climate change.

Why, then, is multilateral lending so skewed toward MICs? The reason is rooted in the MDB financing model. International lenders like the World Bank, the African Development Bank, and the Inter-American Development Bank rely on their perfect credit ratings to borrow cheaply and lend at higher rates to MICs that have not yet reached investment grade status or lost it.

At the same time, lending to LICs is somewhat separate and financed mostly by direct contributions from shareholding governments to LIC-focused bodies like the World Bank’s International Development Association. Without lending to MICs, the argument goes, the MDB model will not be viable. But with more MICs graduating to investment grade ratings, multilateral lending could eventually dwindle.

Many LICs have been trying to reduce their dependence on MDBs; several countries have even managed to borrow in international financial markets for the first time in decades. But the current confluence of economic and geopolitical crises has stalled these plans. In the face of aggressive monetary tightening, most LICs have effectively lost access to capital markets, leading to painful negotiations with creditors and a looming debt crisis.

Ghana’s recent default could be a harbinger of future financial calamities. In recent years, the emergence of non-traditional creditors like China has allowed LICs to diversify their borrowing. But the opaque nature of resource-backed loans has raised doubts about the sustainability of such financing, which seems to have dried up.

There are, however, some encouraging signs that China might join the Bretton Woods institutions in allowing LICs to restructure their debts. While MDBs should increase their lending to LICs, doing so is more complicated than many seem to realise. A major obstacle is these countries’ limited absorptive capacity, which leads to a scarcity of bankable projects.

Likewise, the fact that most LICs have underdeveloped private sectors makes it difficult to scale up investments, particularly for lenders like the World Bank’s International Finance Corporation, which focuses on support for private firms. Moreover, the International Monetary Fund’s (IMF) strict debt limit policies can impede developing countries’ ability to borrow from MDBs – preventing LICs from accessing dozens of billions of dollars at a time when they need it most.

There is no easy solution to this conundrum. Sending MDB staff to LICs could help to build these countries’ institutional capacities and implement projects. And increased coordination between multilateral lenders and the IMF could help to prevent future bottlenecks.

But merely pressuring MDBs to lend more could be ineffective and even counterproductive. For example, lenders could be tempted to prioritise budget support – designed to encourage developing countries to undertake structural reforms that they might have pursued anyway – over longer-term investment projects.

Simply put, lending more is not enough. To benefit LICs and their populations, international lenders must also focus on scaling up meaningful, transformative investments. Then, and only then, will the MDB model finally reach its full potential.
