Spanish Resource Curse
The Spanish Resource Curse describes the historical pattern by which Spain's enormous windfall of New World silver, particularly from the Potosí mines discovered in 1545, failed to generate lasting prosperity because Spain's feudal Catholic institutional structure directed wealth toward religious spending and European wars rather than productive investment, causing Spain to go bankrupt multiple times in the 16th century despite controlling the world's greatest mineral wealth, while Protestant Dutch and English merchants captured the commercial benefits.
The resource curse is the well-documented historical and economic pattern in which extraordinary mineral wealth paradoxically weakens rather than strengthens national economies, because it allows elites to extract revenue without building productive institutions, removes the competitive pressure that drives innovation, and creates political conflict over who controls the windfall rather than productive collaboration to grow it. Spain is the archetypal historical case of the resource curse at civilizational scale.
Spain's institutional structure had three specific failure modes. First, the feudal exemption: Spanish nobility and clergy paid no taxes and contributed no productive economic activity, they consumed surplus without generating it. With New World silver financing the monarchy, there was no pressure to reform this extractive elite. Second, Catholic theology's economic orientation: the Church directed investment toward religious projects (magnificent cathedrals, masses for the dead, festivals, religious orders) rather than productive industry, and its condemnation of usury restricted financial innovation. Third, the monarchy's strategic priorities: rather than using New World silver to develop Spanish industry, Philip II and his successors spent it on the Habsburg's European wars, the Dutch Wars of Independence, the Armada against England, the Italian conflicts, which were simultaneously economically ruinous and ultimately unsuccessful.
The result was structural: Spain went bankrupt in 1557, 1560, 1575, 1596, 1607, 1627, 1647, 1652, and 1662, despite being the world's largest empire. The silver flowed through Spain to the Protestant merchants of the Dutch Republic and England who supplied the manufactured goods the Spanish Empire consumed but did not produce. Max Weber's thesis, that Protestant theology created capitalism's psychology, is partly confirmed by this contrast: Protestant England and the Dutch Republic accumulated the institutional advantages that Catholic Spain's structure prevented. Spain exemplifies the 'resource curse'; Protestant northern Europe exemplifies the opposite dynamic, where the absence of easy extractive wealth forced the development of productive commercial institutions.

Frequently asked questions
Why did Spain's enormous New World wealth not make it prosperous? +
Three institutional failure modes: (1) feudal exemption, nobility and clergy paid no taxes and produced nothing; (2) Catholic economic orientation, investment toward religious projects rather than industry; (3) imperial wars, silver spent on ruinous European conflicts rather than productive development. Spain went bankrupt nine times in the 16th–17th centuries while being the world's largest empire. The silver flowed through to Protestant Dutch and English merchants who supplied goods Spain couldn't produce.
