Sol: 1) Free banking refers to the time period when banks are allowed to issue their own currency notes(that is not possible in general case), without any intervention of central bank or any other agencis.Notes issued on the behalf of commodities like gold, silver etc.
When banks get no fear , increase the money supply due to whcih things not look so expansive and the worth of the money get reduced even to zero.
Banks in order to enjoy the benefits of free banking grant more loan, enjoy their own interest rates. having their own reserve requirements. Granting more loans lead to increase in money supply that increases the demand of all the goods and services due to which condition of inflation arises. but shouldn't treated as hyperinflation as only exists for a shorter period of time. once the things get normal or the at the end of "Free banking era" , control comes under the central govt. ( The FED), price started getting stabilize.
hence should not be treated as Hyprinflation.
Can see the case of " free banking era" of U.S.A, will find that many banks shut down , only the state-chartered banks exists issue their own currency on behalf of gold,silver etc.
