What is a problem for the economy of the new nation was that?

A significant problem for the economy of the new nation was the lack of a stable currency and a unified financial system. This led to difficulties in trade, as different states issued their own currencies, creating confusion and undermining economic confidence. Additionally, the new nation faced substantial debt from the Revolutionary War, straining resources and complicating efforts to establish a robust economic foundation. These challenges hindered the development of a cohesive economic policy and infrastructure necessary for growth.
