Who controlled us banking systems north or south?

The banking systems in the United States prior to the Civil War were primarily controlled by the North, which had a more developed financial infrastructure. Northern states established a network of banks and a more robust currency system, while Southern states relied heavily on agriculture and had fewer banking institutions. The North's industrial economy also supported a greater demand for banking services, further solidifying its control over the financial system. Consequently, the North played a dominant role in shaping U.S. banking policies and practices during that era.
