The reason for the price rise is simple: The total money supply had risen from $109 million in 1830 to $159 million in 1833, an increase of 45.9 percent, or an annual rise of 15.3 percent. Breaking the figures down further, the total money supply had risen from $109 million in 1830 to $155 million a year and a half later, a spectacular expansion of 35 percent. This monetary expansion was spurred by the still-flourishing Bank of the United States, which increased its notes and deposits from January 1830 to January 1832 from a total of $29 million to $42.1 million, a rise of 45.2 percent. The total money supply rose from $150 million at the beginning of 1833 to $267 million at the beginning of 1837, an astonishing rise of 84 percent, or 21 percent per annum.[2]
The notes and deposits of the BUS had risen, from January 1823 to January 1832, from $12 million to $42.1 million, an annual increase of 27.9 percent. This sharp inflation of the base of the banking pyramid led to a large increase in the total money supply, from $81 million to $155 million, or an annual increase of 10.2 percent. Clearly, the driving force of this monetary expansion of the 1820s was the BUS, which acted as an inflationary spur rather than as a restraint on the state banks.
