What problems did the articles of confederation gave the u. s. economy?

Below are the problems of the articles of confederation:

1. Since the Congress had the privilege to manage all types of American cash, the Articles neglected to require a particular type of money. This implied the national government could print cash, however, each state could also. Thusly, America had no uniform arrangement of cash which made the exchange between the states, and with remote substances, considerably more troublesome and less effective. 

2. Congress neglected to shield American from the proceeding with the danger of Britain following the Revolutionary War. Not long after marking the Treaty of Paris in 1783, Britain started to break the understanding. 

3. The national government neglected to concoct the assets to raise an armed force equipped for putting down the insubordination. It took a gathering of rich traders from Massachusetts pooling their assets to pay for a local army.
