Most people assume the resource curse begins when oil starts flowing. The evidence suggests otherwise. In country after country, the damage begins at the moment of discovery — sometimes a decade before the first dollar of revenue arrives.
Most people assume the resource curse begins when oil starts flowing. The evidence suggests otherwise. In country after country, the damage begins at the moment of *discovery* — sometimes a decade before the first dollar of revenue arrives.
This is the presource curse: the pattern of fiscal overexpansion, premature borrowing, governance distortion, and political instability that resource-rich countries exhibit during the gap between discovery and production. It is poorly understood, rarely diagnosed in time, and almost entirely absent from policy advice to resource-discovering countries.
How It Works: Four Channels
Premature Borrowing
Governments borrow against future revenues — often on unfavourable terms — before any production begins. Debt accumulates when repayment capacity is still theoretical.
Fiscal Overexpansion
Public spending surges in anticipation of windfalls. Wages rise, headcounts grow, and commitments are made that are hard to reverse if production underperforms or prices fall.
Governance Distortion
Political competition shifts toward capturing anticipated rents rather than delivering services. Regulatory and institutional capacity erodes before revenues arrive to test it.
Expectation Shocks
Citizens and political actors form expectations of rapid improvement. When reality lags, the result can be instability, populist policy pivots, or erosion of institutional trust.
Three Cases — and a Risk on the Horizon
Ghana
Oil · Discovery 2007
Fiscal deficit widened sharply in the years before Jubilee field production began. By the time revenue arrived, the IMF was already back — with a $918m programme and sharp conditionality.

Gas · Discovery 2010
Hidden debts of over $2 billion accumulated during the presource period. The scandal broke in 2016 — six years before LNG exports began. Fourteen donors withdrew simultaneously.

Oil & Gas · Discovery 2014–16
A decade of systematic debt misreporting. $7 billion in hidden liabilities. When production began in June 2024, Senegal entered the revenue phase with debt above 100% of GDP and an IMF programme suspended.

Malawi has no single transformative resource discovery — but a wave of new mining project investments has generated expectations of substantial revenue and growth. The presource curse does not require a Jubilee-scale event. A portfolio of anticipated investments in a low-capacity state can generate identical dynamics.
Read Malawi briefThe Key Extension: Trigger is Anticipated Wealth, Not Discovery
The presource curse is not limited to oil and gas discoveries. In countries with low resource-sector maturity, major new mining investments and project commitments can trigger the same mechanisms — premature borrowing, unrealistic growth forecasts, governance strain — even without a single large discovery event.
The trigger is anticipated wealth, not the source of it. This makes the presource curse directly relevant to the new generation of critical mineral and mining investment in sub-Saharan Africa.
Why This Matters for Policy
The presource period is the most important — and most neglected — window for policy intervention. Once debt has accumulated and expectations have been set, the range of feasible policy choices narrows sharply.
Evidence-based advice delivered *before* the curse takes hold can prevent growth collapses that cost billions in lost output and leave millions worse off. A modest investment in research and advisory capacity at this stage has asymmetric returns.
✓ Policy Checklist: Avoiding the Presource Curse
- → Manage expectations explicitly: communicate realistic, conservative revenue timelines publicly
- → Design fiscal rules that bind during the presource window — not just post-production
- → Require parliamentary approval and independent auditing of all borrowing within 3 years of a major discovery
- → Anchor fiscal plans to the pessimistic revenue scenario, not the central estimate
- → Build governance institutions before revenues arrive — not in response to them
- → For critical minerals contexts: apply the same safeguards as for petroleum, regardless of whether there is a single large discovery
