The windfall that can impoverish what it enriches

A giant deposit ought to make a country's fortune. It can also ruin it: by inflating its currency, it smothers its other sectors; and the rent corrupts its institutions. Guyana, which in five years became the fastest-growing economy in the world, is today the laboratory for it.

To discover a giant deposit beneath your feet: one imagines a fortune assured. Economic history often tells the opposite story. From the weight of statistics, it has been observed that the countries best endowed with natural resources frequently grow more slowly than the rest, when they do not collapse outright. The wealth of the subsoil can impoverish the nation it ought to enrich. Two mechanisms combine to bring this about: one strikes the currency, the other erodes the institutions.

1 The paradox of plenty

What ought to enrich can, statistically, handicap.

The puzzle
When the gift becomes a burden
It is called the "paradox of plenty": economies rich in oil, gas or minerals tend often to grow more slowly, to develop less well, and sometimes to sink into instability. This is no mechanical fate, but a regularity strong enough to have puzzled economists for half a century. Two forces explain it, and they must be kept apart: "Dutch disease", a monetary mechanism that smothers the other sectors; and the "resource curse", an institutional mechanism, by which the rent weakens the state itself.
2 Dutch disease

The monetary mechanism: the windfall appreciates the currency and kills the other exports.

The mechanism
The too-strong currency that strangles industry
The term was coined by The Economist in 1977, to describe the decline of Dutch industry after the exploitation of the large Groningen gas field. The mechanics, modelled by the economists Corden and Neary in 1982, come down to two effects. The "spending effect": the foreign currency drawn from the windfall pours in, domestic demand swells, the currency appreciates, and national goods become too dear against imports. The "resource-movement effect": labour and capital desert industry and agriculture for the booming sector. The result: a strong currency, a flourishing resource sector, and the whole rest of the economy withering alongside.
3 The curse, wider than the exchange rate

The institutional mechanism: the rent that corrupts the state.

Beyond the currency
When living off the rent excuses one from accountability
The "resource curse" (an expression popularised by Richard Auty in 1993, and backed by the famous study of Sachs and Warner in 1995) goes beyond the question of the exchange rate. The rent opens other wounds: the volatility of prices, which makes budgets erratic; rent capture and corruption, more tempting than patient productive work; underinvestment in education, judged less urgent while the oil flows; and above all a subtle political tilt. A state that finances itself through the resource rather than through taxation ceases to depend on its citizens: it is less accountable to them. Democracy and institutions are weakened as a result. The windfall can thus buy, along with roads, the unaccountability of those who manage it.
4 Guyana, the textbook case

A full-scale laboratory: a micro-state turned oil giant.

The laboratory
Eight hundred thousand people, an ocean of oil
No country illustrates the stakes better than Guyana. In 2015, a consortium led by ExxonMobil discovered the Stabroek field off this small South American country: about 11 billion recoverable barrels. Production began in late 2019, and everything took off. GDP surged by 43.6% in the single year 2024; over the period, Guyana posts the fastest growth in the world, averaging 47% a year. Income per head has almost tripled in two years, tipping the country into the "high income" category. Production is aiming for 1.3 million barrels a day around 2027. All of this for a population of about 800,000 souls: the windfall, here, is out of all proportion to the country that receives it.

5 The safeguards, and the IMF's warning

What Guyana is putting in place, and what the IMF fears.

Prudence, under watch
A fund, low debt, and a number-one risk
Guyana is not blind to the danger. It has created a sovereign fund, the Natural Resource Fund, with a tapering withdrawal rule and parliamentary oversight, to set the windfall aside rather than squander it; its public debt remains low, around 24% of GDP. The International Monetary Fund, in its review of May 2025, is rather reassuring: Dutch disease is not yet present, since the non-oil sectors are themselves also still growing. But it explicitly makes it its number-one risk: overheating, incipient inflation and the appreciation of the real exchange rate, if not contained, would produce "the effects commonly associated with Dutch disease". All the ingredients of the risk are in place; the question is whether the discipline will hold.
6 Those who managed to turn the windfall around

The proof that the curse is not a fate.

The models
Norway, Botswana, Chile: the well-managed blessing
Three countries show that a resource can enrich lastingly. Norway placed its oil windfall in a sovereign fund that has become the largest in the world (about $1.8 trillion), with a golden rule: to spend each year only the fund's expected return, never the gross revenues. Botswana, one of the poorest countries in the world at its independence, converted its diamonds into development thanks to solid institutions and investment in education. Chile gave itself a structural-balance rule that disconnects public spending from the price of copper: one saves when the metal is dear, one supports the economy when it falls. In all three cases, discipline turned the rent into a lasting endowment.
7 Those who sank

The other side: the greatest wealth turned into the greatest ruin.

The wrecks
Venezuela, Nigeria: the wealth that ruins
At the other end of the spectrum, Venezuela holds the world's largest oil reserves; yet its economy collapsed by about 75% from 2013, in hyperinflation and mass emigration. The rent, diverted and undiversified, did not protect the country: it masked its fragility until the collapse. Nigeria offers the textbook case of Dutch disease: its agricultural exports, which made up about 42% of the total in 1970, fell below 3% in 1985, ground down by the strong currency of oil; poverty, for its part, did not recede. Angola illustrates the same drift, between real appreciation and persistent dependence. In all these cases, the resource did not create the fragility; it multiplied it.
8 The decisive variable

Let us be rigorous: neither a fate, nor an automatic blessing.

The counterpoint
"Institutions decide"
The curse is in no way deterministic, and this must be said plainly. Recent research has shifted the debate: the resource is neither a blessing nor a curse in itself; everything depends on the quality of the institutions. The economists Mehlum, Moene and Torvik summed it up in 2006 in a formula: "institutions decide". Where they are "producer-friendly", the resource enriches; where they are "grabber-friendly", it impoverishes. Others, such as Brunnschweiler and Bulte (2008), go further and dispute the raw result of Sachs and Warner: the usual statistic would measure dependence on resources, not abundance, and would confuse cause and consequence. Caution is called for: the windfall condemns no one in advance.
The magnifying mirror
The right image is therefore not that of a poison, but of a magnifying mirror. The resource amplifies what a country already is: it turns a well-governed state into a Norway, and a fragile one into a Venezuela. It creates neither virtue nor vice; it reveals and multiplies whichever is present.
9 A choice, not a fate

The windfall does not impoverish mechanically: it puts to the test.

The lesson
What the wealth of the soil demands of those who receive it
The windfall that can impoverish what it enriches is no absurd contradiction: it is a test. It offers a country the means of its future, provided it has the discipline not to spend the whole rent, the rigour to set the wealth aside, the institutional solidity to resist capture. Failing that, it appreciates the currency, ruins industry, corrupts the state, and leaves, once the deposit runs dry, a country poorer than before. Guyana is playing out this wager live, before our eyes, and under the Venezuelan threat to its Essequibo territory. From its success or its failure, we shall draw the next lesson of a very old paradox.
The compass
Two ills, one paradox. Dutch disease (the strong currency that strangles the other sectors) and the resource curse (the rent that corrupts institutions) can turn a windfall into a handicap.
Guyana, the laboratory. Growth of ~47%/yr, income per head tripled; a sovereign fund and low debt for safeguards, but the IMF makes it its number-one risk.
Institutions decide. Norway and Botswana for success, Venezuela and Nigeria for failure. Neither fate nor blessing: a choice. This sheet sheds light on a debate; it does not constitute investment advice.
The other face of resources
This dossier extends a theme we approached from the opposite angle: the battle for copper, where the scarcity of a resource becomes a source of power. Here, it is abundance that becomes a trap. To lack a resource or to overflow with it: in both cases, everything turns on how one prepares for it.
