What is the one commonality between capitalism and merchantilism

Capitalism is an economic system and an ideology based on private ownership of the means of production and their operation for profit.

Mercantilism was a type of national economic policy designed to maximize the trade of a nation and especially to maximize the accumulation of gold and silver.

So in other words,. Mercantilism is a type of economic system based on international trade. Merchants export goods to other nations and import goods to their own nation in hope of making a profit. Because many businesses in a modern capitalist economy do the exact same thing, mercantilism can be interpreted as an early form of capitalism.
