United States vs Gambia
Broad money supply, growth and observation dates, side by side.
Native-currency series are rescaled by each economy's own latest USD ratio: the shape of the line is exact, the level of older points is approximate. Use the country pages for the source figures. Crossings do not establish when one economy's money stock overtook the other at historical exchange rates.
UNITED STATES's money stock is 15057165.2% larger than GAMBIA's — $30.68T against $203.77M. Average annual growth is 6.6% for United States and — for Gambia. These are nominal money stocks at each economy's stated observation date.
"So the bigger number is the richer country?" No. Broad money counts deposits and currency outstanding, not wealth, not output and not purchasing power. A country can have a large money stock and a poor population, and the reverse. It is also not comparable to GDP, and the two series here are measured on different dates by different agencies.
