Mismanagement of printed currency resulted in inflationary periods. The colonies often had insufficient bullion left over to circulate in their own markets, so they issued paper currency to replace it. Inflation and taxation: The British government demanded that trading be conducted using gold and silver bullion, ever seeking a positive balance of trade.In turn, slaves were returned to America or the West Indies and traded for sugar and molasses. The colonies provided rum, cotton, and other products demanded by African imperialists.
This fostered the development of the slave trade in many colonies, including America.
