Who led the anti federalists movement which supports a decentralized banking system?

The correct answer is Thomas Jefferson

Explanation:

Thomas Jefferson was a staunch anti-federalist. Federalists believed that most of the power should remain with the central government. Today, this is usually termed as 'Big Government'

However, Thomas Jefferson believed that the States should be largely independent and should hold the power to decide local laws and taxes.

A decentralized banking system was at the core of the anti-federalists movement as it would provide an independent financial system for each States.
