Mercantilism

• 1. Introduction

  ›

  Mercantilism shaped the economic ambitions of European states for roughly 250 years, from the 15th century through the early 19th. In 1639, Claude Lorrain painted a sun-drenched seaport at the precise height of the system's influence, with ships, commerce, and the promise of bullion filling every corner of the canvas. That image captures something real: the entire political order of the age ran on the idea that national power was measured in gold, and that every trade with a foreigner was a competition to be won. How did a set of ideas with no single founding theorist come to govern empires? Why did it take nearly three centuries for anyone to dismantle it? And what does it mean that some economists still see it alive today?

• 2. The Bullion Obsession

  ›

  Antonio Serra, an Italian economist, wrote what scholars consider one of the first treatises on political economy in 1613, titled A Short Treatise on the Wealth and Poverty of Nations. His starting premise, shared by nearly every mercantilist thinker, was that a nation's wealth lived in its stock of precious metals. Gold and silver were not just convenient payment; they were the scoreboard of national greatness. Early evidence of these ideas appeared even earlier in Venice, Genoa, and Pisa, where city-states actively managed control of Mediterranean bullion trade.

  Mercantilist writers were not, however, simple hoarders. Thomas Mun, an English merchant born in 1571, argued that money needed to circulate to generate economic activity. Mun's posthumously published England's Treasure by Forraign Trade, probably written in the late 1620s and published in 1664, became what Adam Smith later called the archetype of mercantilist texts. Mun's insight was that a nation grew richer by selling more abroad than it bought, not simply by locking bullion in a vault.

  Philipp Wilhelm von Hornick, an Austrian lawyer, laid out the logic most crisply. In his 1684 work Austria Over All, If She Only Will, he detailed a nine-point program: use every patch of domestic soil, convert raw materials into finished goods at home, ban gold and silver exports, discourage all foreign imports, and constantly seek foreign buyers for domestic surplus. Raw materials, he argued, gained value when worked by domestic labor. That value was the point. Gold flowing out for foreign luxuries was wealth surrendered.

• 3. England Builds the System

  ›

  "We must always take heed that we buy no more from strangers than we sell them, for so should we impoverish ourselves and enrich them." That line appeared in a 1549 text now attributed to Sir Thomas Smith, and it captures the guiding logic of the Elizabethan approach. Queen Elizabeth I, who reigned from 1558 to 1603, pushed trade and navigation acts through Parliament and issued direct orders to the Royal Navy to protect English shipping. Her court sought to break the Spanish grip on Atlantic trade and to push English merchants into more distant markets.

  Gerard de Malynes, active roughly from 1585 to 1641, and Thomas Mun, 1571-1641, gave the system its intellectual architecture. Josiah Child, who died in 1699, refined and extended their ideas. The first Navigation Acts, formalizing these protectionist instincts into law, passed Parliament in 1651 and 1652 under the English Commonwealth. They barred foreign merchants from England's domestic trade and reserved colonial commerce for English ships.

  Mercantilism reached its English peak during the Long Parliament government of 1640-60. Robert Walpole was another major proponent in the early 18th century. Adam Smith praised the Navigation Acts of 1660-1760 as instruments that genuinely built the British merchant fleet and helped turn Britain into a global naval and economic power. British mercantilist policies also left a lasting domestic imprint: the conversion of what contemporaries called wastelands into agricultural land, including drainage projects like The Fens, followed directly from the mercantilist principle that all resources must be used at their highest value.

• 4. Colbert and French State Power

  ›

  In 1539, France banned the import of woolen goods from Spain and parts of Flanders. The following year came restrictions on bullion exports. French mercantilism began as a reflex of royal power asserting itself over commerce, and over the rest of the 16th century it grew into a full ideology of state control. Jean-Baptiste Colbert gave it its definitive shape.

  Colbert served as Controller-General of Finances under King Louis XIV from 1665 to 1683, a span of 22 years. His operating principle was that the state should govern the economy exactly as it governed diplomacy: the king's interests came first, above merchants and above everyone else. Under his direction, the French government organized industries into guilds and monopolies, regulated production through more than a thousand directives specifying how different goods should be made, and actively imported foreign artisans and craftsmen to build domestic expertise. Colbert also reduced internal tariffs and built roads and canals to move goods more efficiently within France.

  Colbert's results were real. France's industrial output grew substantially and France became the dominant European power during his tenure. Where he fell short was overseas trade: Britain and the Dutch Republic remained supreme there. France applied the same mercantilist logic to its North American colonies, extracting maximum material benefit while investing minimally in colonial development. The trading monopolies it created there, including La Compagnie des Cent-Associes, founded in 1627 by King Louis XIII, and the Communaute des habitants in 1643, were the first corporations to operate in what is now Canada.

• 5. Wars, Colonies, and Trade as Weapon

  ›

  Four Anglo-Dutch Wars, spanning 1652 to 1784, can be traced directly to mercantilist logic. When governments assumed that global trade was fixed in total volume, the only way to gain was to take. Wars were not incidental to the system; they were a natural extension of it. The Franco-Dutch Wars from 1672 to 1678 followed the same reasoning. Most conflicts had other causes, but mercantilism sharpened every rivalry by framing trade competition as a zero-sum contest with a clear enemy.

  The drive for colonies followed identical reasoning. Nations expended enormous effort to conquer territories that could supply gold, as in Mexico, or sugar, as in the West Indies, and to seal those territories as exclusive markets. Companies with government-guaranteed monopolies, such as the Dutch East India Company and the Hudson's Bay Company in present-day Canada, carried European power across the globe under an explicitly mercantilist charter.

  Marxist economist Giovanni Arrighi, who lived from 1937 to 2009, analyzed mercantilism as resting on three interlocked foundations: settler colonialism, capitalist slavery, and economic nationalism. He argued that slavery was partly a condition and partly a result of successful settler colonialism. France's Atlantic trade made this connection explicit: the route ran from France to Africa to the Americas and back, with enslaved African labor in the New World generating the commodity surplus that sustained the entire cycle.

  Spain's experience showed the system's fragile side. Early gains from New World gold and silver flooded the treasury, but the influx drove severe inflation. Heavy royal intervention froze production at fixed levels, gutting the efficiency of the Castilian textile industry year by year. Spain required much of its agricultural land to be devoted to sheep rather than grain, which produced food shortages in the interior and forced grain imports from the Baltic. Spain defaulted in 1557, again in 1575, and again in 1596.

• 6. The Intellectual Dismantling

  ›

  John Locke, in 1690, argued that prices vary in proportion to the quantity of money. That single observation cut at the heart of the mercantilist program: if more gold raised prices, a permanent trade surplus would eventually make domestic exports too expensive to sell abroad. David Hume pushed the argument further, pointing out that bullion flowing into a country would raise prices there while the exporting country's prices fell, until the trade advantage reversed on its own.

  Adam Smith's The Wealth of Nations, published in 1776, made the critique systematic. Smith spent a large portion of the book attacking mercantilism, though scholars have noted that his characterizations sometimes simplified mercantilist positions. His core charge was what he called the "popular folly of confusing wealth with money": bullion was just another commodity and deserved no special treatment. Smith also saw the mercantile system as a conspiracy by manufacturers and merchants against consumers, a reading that led Robert E. Ekelund and Robert D. Tollison to later describe mercantilism as a rent-seeking society. David Ricardo, in 1817, completed the theoretical demolition by fully working out comparative advantage: two countries could both gain from trade even when one was more efficient at producing everything.

  The transition away from mercantilism was uneven. Britain removed mercantilist regulations steadily through the 18th century, and Parliament's repeal of the Corn Laws under Robert Peel in 1846 became the symbol of free trade's arrival. In France, economic controls remained royal until the Revolution. In Germany, mercantilist ideas persisted as a serious ideology well into the early 20th century. James Steuart's Principles of Political Economy, published in 1767, is often cited as the last major mercantilist work before Smith made the system intellectually untenable.

• 7. The Long Afterlife

  ›

  John Maynard Keynes, born in 1883, offered a partial rehabilitation in the 20th century. He affirmed that stimulating production mattered as much as encouraging consumption, that the pre-paper-money focus on bullion supplies was rational within its era, and that mercantilist policies helped lower domestic interest rates while attracting foreign investment through a favorable balance of trade. Paul Samuelson, writing within a Keynesian framework, put it bluntly: with employment below full capacity and output below its potential, the debunked mercantilist arguments turned out to be valid.

  The American School of economics, which dominated United States policy from the Civil War through the mid-20th century, drew directly on mercantilist principles. Its three core elements were selective high tariffs, especially from 1861 to 1932; government investments in infrastructure; and a national bank oriented toward productive enterprise. Alexander Hamilton's Report on Manufactures in 1791 is cited as its founding document.

  Robert J. Samuelson, writing in the 14th of May 2007 issue of Newsweek, described China's trade strategy as neo-mercantilist, arguing it threatened the post-World War II international economic order. After Donald Trump's 2024 re-election, Serbian-American economist Branko Milanovic described Trump's tariffs, trade blocs, and barriers against China as neo-mercantilism, calling it a symbolic end to global neoliberalism. Michael Strain of the American Enterprise Institute offered a harsher assessment, describing the policies as a combination of genuine mercantilist belief and what he called shocking ignorance about how the global economy works. The debate Antonio Serra first entered in 1613 is plainly not over.
