Alongside the commercial markets of the last module sits a parallel world of official and concessional finance — cheaper, longer, more patient money from multilateral institutions and other governments, but with strings and politics of its own. This module covers that world: the IMF and World Bank, the rise of China, and the central trade-off between cheap conditional money and expensive free money.
Concessional finance and the grant element
Money below market terms
Concessional finance is lending on terms more favourable than the market — below-market interest rates, long maturities (20–40 years), and grace periods (years before repayment starts). The degree of concessionality is measured by the grant element: the difference between the loan's face value and the present value of its repayments (discounted at a market rate), as a percentage. A pure grant has a 100% grant element; a market loan, roughly 0%. Concessional loans typically have grant elements of 35%+ — they are part loan, part gift. The sources: the IMF, the World Bank's soft-loan arm (IDA, for the poorest countries), the African Development Bank, and bilateral donors. Concessional finance is the cheapest money a poor country can get — which is exactly why the move to expensive commercial Eurobonds (last module) was a step up in cost and risk.
The IMF and conditionality
The IMF lends to countries in balance-of-payments or fiscal difficulty through a menu of facilities (the African Macro 101 course surveys them): the Extended Fund Facility and the concessional Extended Credit Facility for programme lending, the Rapid Credit/Financing Instruments for emergencies, and newer facilities like the Resilience and Sustainability Trust. IMF money is cheap and unlocks other financing (an IMF programme is a seal of approval that catalyses other lenders), but it comes with conditionality — policy commitments (fiscal targets, reforms) the country must meet to keep receiving funds.
The conditionality trade-off
Conditionality is the defining feature and the central controversy of IMF (and much official) lending. The case for it: the lender needs assurance the country will fix the problems that caused the crisis and be able to repay; conditionality can also provide a useful external anchor and political cover for reforms a government wants but cannot pass alone. The case against: conditions have often been intrusive, ideologically loaded (the structural-adjustment era's one-size-fits-all liberalisation, the Development and Political Economy courses), socially painful (austerity hitting the poor), and imposed without domestic ownership — and reforms imposed from outside without a domestic coalition that owns them get reversed (the political-economy-of-reform lesson). The modern Fund has tried to streamline conditionality and emphasise ownership and social spending floors. The trade-off for a borrowing country is real: cheaper, catalytic money in exchange for some loss of policy autonomy and the political cost of the conditions — exactly the freedom-vs-cost trade-off that made conditionality-free Eurobonds so tempting.
China as a creditor
The transformative development of the last two decades is China's emergence as the largest bilateral official creditor to Africa, lending heavily for infrastructure (roads, railways, ports, power) through the Belt and Road Initiative and its policy banks. Chinese lending filled a real gap (Western official finance had retreated from infrastructure) and built genuinely useful assets — but it raised concerns: opacity (terms often undisclosed, complicating debt transparency and restructuring), collateralisation (some loans secured against commodity exports or revenues), and the contested 'debt-trap diplomacy' thesis (the claim that China deliberately lends unsustainably to seize strategic assets on default).
The debt-trap debate, honestly
Horn, Reinhart, and Trebesch (2021) documented the scale and opacity of China's overseas lending ('hidden debts' not captured in standard statistics). But the careful evidence (Brautigam and others) largely rejects the simplistic 'debt-trap diplomacy' narrative — the Hambantota-port story is more complicated than the meme, China has generally restructured rather than seized assets, and African governments were willing, agential borrowers, not passive victims. The substantive problems are real but more mundane: opacity (which obstructs debt management and restructuring — you cannot restructure debt whose terms you don't know), the coordination problem China's scale creates for restructuring (module 7 — China as a large, non-Paris-Club creditor that must be brought into any deal), and sometimes poor project selection. The analyst's takeaway: avoid both the alarmist 'debt-trap' framing and naive enthusiasm; Chinese finance is a major, useful, but opaque and coordination-complicating source whose risks lie in transparency and restructuring, not in a grand seizure conspiracy.
Choosing among sources
A government's financing choice is a portfolio decision across these sources, each with a distinct profile: concessional multilateral money is cheapest and most patient but limited in size and conditional; Eurobonds are large and free but expensive and risky; Chinese loans are large and infrastructure-focused but opaque; domestic debt avoids currency risk but is shallow and crowds out. The prudent approach maximises concessional finance (the cheapest), uses commercial and Chinese borrowing selectively for productive investment, manages the resulting currency and refinancing risks, and keeps the whole structure transparent and sustainable. The mistake of the 2010s — substituting expensive, risky commercial debt for cheaper concessional finance because it was conditionality-free, while taking on opaque Chinese loans alongside — produced exactly the debt distress the next module's restructurings address.
Exercise
A government needs $2 billion to fund an infrastructure programme. It can get up to $800m concessional from the World Bank/AfDB (cheap, long, but conditional and tied to appraised projects), issue a $2bn Eurobond (free to spend, but 8% and hard-currency), or take a $2bn Chinese policy-bank loan (for a specific railway, opaque terms, possibly collateralised). (1) Compare the three sources on cost, conditionality, risk, and transparency. (2) Recommend a financing mix and justify it. (3) Explain the conditionality trade-off the government faces with the concessional option. (4) What transparency and coordination problems would the Chinese loan create if the country later needed to restructure?
