"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.
