The Price Revolution in Europe
Between approximately 1520 and 1650, European prices roughly tripled. This sustained inflation — modest by modern standards but unprecedented in a world accustomed to centuries of price stability — was called the Price Revolution by later historians. The historian Earl Hamilton documented it in detail in his 1934 study American Treasure and the Price Revolution in Spain, arguing that the influx of American silver was its primary cause.
The Evidence
Hamilton matched Spanish silver import records with commodity price data from Andalusian markets and found a strong positive correlation: as silver imports rose, prices rose. The transmission mechanism was straightforward: a larger money supply chasing a relatively fixed supply of goods produces higher prices. The quantitative theory of money — famously summarised as MV = PQ (Money × Velocity = Price level × real Output) — operated across a hemisphere.
The price rise was not uniform. Spain experienced the earliest and most severe inflation, as the first point of silver entry. Prices then rose across Europe as silver flowed through trade networks. Wages, being stickier than goods prices, rose more slowly — meaning real wages fell for much of the 16th century in regions receiving silver. Landowners with fixed rents saw their real income erode; creditors who had lent at fixed rates in the pre-inflation period were repaid in depreciated money.
Winners and Losers
The Price Revolution produced systematic redistributive consequences:
Beneficiaries: Debtors who had borrowed before the inflation and repaid in depreciated money. Merchants who bought goods cheaply in one region and sold them in another, profiting from price arbitrage. Farmers in commercialised agricultural regions who could sell output at rising prices while paying fixed rents.
Losers: Fixed-income receivers — landlords on long leases, creditors, pensioners, wage earners. The Tudor scholar Thomas Smith observed in 1549 that landowners were being "eaten alive" by inflation that eroded the real value of their fixed rents while their costs rose.
The Revisionist Debate
Hamilton's silver-inflation thesis has been challenged by later historians. Some argue that population growth — European population roughly doubled between 1400 and 1600 — was as important a driver of price increases as monetary expansion, increasing demand for food and pushing agricultural prices up independently of silver. Others argue that the correlation between silver imports and prices is less clean than Hamilton presented.
The current historical consensus is that both factors contributed: silver expanded the money supply while population growth increased real demand. The Price Revolution illustrates that causation in historical price episodes is rarely monocausal — but the monetary channel was real and significant.
