Available Endpoints
Global M2 (Liquidity)
Methodology: Daily series methodology: each day's value reflects each country's most recently published M2 figure converted to USD at that day's exchange rate. Intra-month movement reflects currency fluctuations only, not changes in the underlying money supply. When a new monthly figure is published by a central bank, that country's value steps to the new figure on the publication date.
