Definition
Commercial capitalism is capitalism in its merchant-driven form. Profit derives from arbitrage — buying cheaply in one place or time and selling dearly in another — rather than from organising production. It is the dominant form from roughly the 16th to the 18th centuries, embodied in the Dutch and English East India Companies, Mediterranean trade, the Atlantic slave triangle, and the spice and sugar trades.
Although production is not yet reorganised around wage-labour at scale, commercial capitalism is genuinely capitalist: capital is invested with the expectation of profitable return, profits are reinvested, and the joint-stock company is invented precisely to pool risk across many investors for ventures too large for any single merchant.
Why it matters
History
Italian city-states, Dutch trading houses, and the chartered companies of London and Amsterdam pioneered the institutional toolkit of commercial capitalism. The Dutch East India Company, founded in 1602, was the first permanent joint-stock company with publicly traded shares — an institutional innovation that allowed capital to be raised at unprecedented scale and held independently of any single investor's life.
By the late 18th century, commercial capitalism's expansion had created the conditions for industrial capitalism: pools of investable capital, a class of wealthy investors looking for returns, and global supply chains for cotton, sugar, and tobacco that would soon feed factory production.
