500 Francs Small

The "Small" designation distinguishes this from the earlier, larger-format 500 Francs series — a size reduction the BRB introduced to cut printing costs, a move common among central African issuers during the 2000s as substrate and logistics expenses climbed. Burundi's franc has operated under chronic inflationary pressure throughout this period, and the 500-franc denomination has progressively lost practical purchasing power while remaining in active everyday circulation.

The print date of 30 April 1945 listed here is almost certainly a catalog data error — that date predates the Burundian state by nearly two decades.
