When considering the economic and development challenges of developing economies in the face of the climate crisis, most people tend to view debt as a complicating factor at best and a source of many of our problems at worst. There are good reasons for this. Rising public debt across the developing world—and the surging interest bills that accompany it—is diverting public funds from already underfunded health and education programs. It threatens to push more countries into outright distress and more people back into poverty.
Yet there is no escaping the fact that debt will continue to be a critical component of the funding developing economies need to meet their sustainable development goals—particularly climate resilience—and fulfill their economic development potential more generally. The challenge, therefore, is to both lend and borrow “better.” What does this mean?
Well, for sure it means ensuring that public borrowing is anchored in sustained fiscal discipline. However, it also means avoiding debt that is very likely to prove unsustainable. While overall debt sustainability is determined by multiple factors, experience teaches us that the rate of economic growth is the most important driver of debt dynamics. There is a simple rule to help determine when the terms of new borrowing are unlikely to prove sustainable over time, at least when it comes to cost: put simply, rates of interest that are likely to exceed the rate of future nominal growth cannot be considered sustainable. The more such rates feature across a public debt portfolio, the greater the likelihood of sovereign debt distress in the future.
Flawed framework
Although there has been much focus on the very high interest rates paid by some developing economies on their Eurobond issuances since the start of 2024, the problem of unsustainably high borrowing costs is also evident in lending by the official sector. In fact, the recent rise in global interest rates has revealed a flawed IMF lending framework for middle-income countries that no longer supports debt sustainability. It is in desperate need of reform.
Let’s start with the central issue of cost. At the start of the millennium, surcharges were introduced on all IMF lending to middle-income countries through the General Resources Account (GRA), which includes Stand-by Arrangements (SBAs), Extended Fund Facilities (EFFs), and Rapid Financing Instruments (RFIs). The surcharge structure comprises a level-based surcharge of 2 percent on GRA borrowing that exceeds 187.5 percent of quota and an additional 1 percent “time-based” surcharge on the portion of GRA credit above this threshold that is outstanding for more than 36 months (or 51 months in the case of the EFFs).
The IMF introduced these surcharges when it was trying to extinguish the flames of the first emerging market debt crises, including by burning through its own capital. The underlying objective of the new surcharges was to dissuade large and prolonged borrowing from depleting the IMF’s resources, particularly among higher-rated emerging market sovereign borrowers. The surcharges worked well, and these countries quickly regained investment grade ratings after the crisis. Years later the approach worked well again: Organisation for Economic Co-operation and Development countries that had been forced to borrow from the Fund during the global financial crisis were able to prepay their IMF liabilities once the worst of the instability problems had subsided, thanks to deep domestic capital markets.
But the world has changed radically over the past 25 years. For a start, the IMF has gone from having precautionary balances of $6.2 billion as of April 1999 to approximately $33 billion as of April 2024. It has also succeeded in making a much-needed pivot, gradually expanding its role as a lender of last resort to become a partner of some of the poorer and most fragile countries in the world at a time when their access to liquidity has been severely compromised.
The scale of IMF lending has also increased. In fact, 187.5 percent of quota is no longer a big deal: as of April this year, 21 middle-income countries had borrowed above this level from the Fund. Compared with a decade ago, the average per capita income of countries with active EFFs has fallen by a factor of 4.
Yet the Fund’s surcharge regime remains unchanged and has exposed fragile sovereign borrowers to the full force of rising world interest rates, even though the IMF is now well capitalized and does not rely on market borrowing to fund its lending arrangements.
Surcharge regime
As of June this year, the minimum all-in interest rate payable on GRA disbursements (this covers SBA, EFF, and RFI disbursements) had surged to 5.1 percent a year, with sovereigns paying 7.1 percent on the portion of their drawings that exceeds 187.5 percent of quota. GRA liabilities outstanding for three years or more (or four in the case of the EFF—less than halfway to final maturity) now have a record interest rate of 8.1 percent. The IMF cannot argue that its lending programs have debt sustainability at heart when its own lending to middle-income countries cannot be considered sustainable.
This is a problem the IMF must address. Incentivizing sovereign borrowers to repay the IMF is not wrong in itself, but it is wrong in a world where most GRA borrowers have no reliable access to alternative sources of sustainable financing. The IMF’s surcharge regime needs to be reformed urgently—either through a radical overhaul that includes caps that take into account the interest rate cycle or preferably by scrapping it outright.
