This paper examines mercantilism as practiced by major trading nations during the sixteenth through eighteenth centuries, focusing on its core goal of accumulating precious metals through export-driven policies, trade regulation, and colonial exploitation. It then outlines Adam Smith's critique of mercantilism in The Wealth of Nations, including his arguments for free trade, specialization, economies of scale, and the principle of the "invisible hand." Finally, the paper considers the paradox that, despite Smith's foundational influence on modern economic thought, most industrialized nations today continue to employ mercantilist-style interventions such as tariffs, subsidies, and regulatory protections.
Mercantilism was practiced by the major trading nations during the sixteenth, seventeenth, and eighteenth centuries. These nations sought to increase exports so they could build wealth by accumulating precious metals, especially gold. To accomplish this, mercantilists favored foreign trade over domestic trade and focused on manufacturing as a means to produce exportable goods rather than on extractive industries such as agriculture.
State actions under mercantilism were aimed at ensuring that a nation sold more goods than it bought. Specifically, governments levied duties on imports, regulated production to secure high-quality, low-cost goods, signed treaties to obtain exclusive trading privileges, and exploited the commerce of their colonies for national benefit. These mercantilist policies eventually led to an oversupply of money and serious inflation.
Adam Smith was a leading critic of mercantilism. In his landmark work The Wealth of Nations, Smith rejected the idea that the wealth of a nation is measured by the size of its treasury. He also argued that free trade benefits both parties through specialization in production, which allows for economies of scale. Under free trade, goods could therefore be obtained at lower cost from abroad than if produced domestically.
Smith further argued that a collusive relationship between government and industry was harmful to the general population. He believed that removing such interference was essential to a nation's economic success.
Smith described the principle of the "invisible hand," by which every individual is led by natural market forces toward his or her own self-interest, and that this process simultaneously benefits society as a whole. In Smith's view, government interference in the market was a hindrance to this natural process rather than a help.
