Originally meant as bonds, they evolved into a currency used as legal tender. As there was no control over the amount to be printed, the value of the assignats exceeded that of the confiscated properties. This caused massive hyperinflation. In the beginning of 1792, they had lost most of their nominal value.

This hyperinflation was stirred up by repeated food shortages. Instead of solving the financial problems, the assignats became a catalyst for (food) riots. Instability continued after the abolition of the monarchy, exacerbated by the wars France faced. This situation impeded the implementation of good financial policies that would reduce debts. Bills such as the Maximum Price Act of 1793 aimed to regulate inflation.

When the Directoire came into power in 1795 the Maximum Price Act was lifted. Hyperinflation reemerged and in the next four years Paris was the stage of yet more riots.

The inflation was finally solved by Napoleon in 1803 by introducing the franc as the new currency. By this time, the assignats were basically worthless.
