What Is the Total Money Supply on Earth Right Now
Money on Earth is measured in layers called monetary aggregates, with the narrowest being M0, which includes physical cash and central bank reserves. Broad measures like M2 include cash, checking deposits, savings accounts, and money market funds. The global M2 money supply has grown significantly in recent years due to central bank policies and digital banking expansion, reaching tens of trillions of dollars across major economies. For the latest figures on the U.S. money supply and definitions, see the Federal Reserve's data on M2 and other aggregates here.
Global wealth is a separate concept from the money supply and includes all assets such as real estate, equities, bonds, and private holdings. Credit Suisse and Knight Frank publish annual Global Wealth Reports that estimate total household wealth across countries. These reports show that the top countries by wealth hold a disproportionate share of global assets, while the majority of adults hold a small fraction of total wealth. The latest Global Wealth Report from Credit Suisse provides detailed regional breakdowns here.
How Much Physical Cash and Digital Money Exists Worldwide
Physical cash in circulation, or M0, is a small share of the total money supply in most advanced economies. The U.S. Federal Reserve tracks currency in circulation, which has grown steadily as demand for cash remained strong even amid digital payments. In contrast, digital money dominates in countries with high mobile payment adoption, where most transactions occur through bank accounts and electronic wallets rather than physical notes. The Bank for International Settlements publishes cross-border data on payment systems and cash usage trends here.
Broad money, including M2 and M3, captures demand deposits, savings, and near-money instruments that can be quickly converted to cash. Central banks around the world, including the European Central Bank and the People's Bank of China, report these figures regularly. The growth of broad money often reflects lending activity, government stimulus, and shifts in how people store value. The ECB's statistical portal provides detailed M3 data for the euro area here.
Who Controls and Tracks the World's Money
Central Banks and Monetary Authorities
Central banks such as the Federal Reserve, European Central Bank, and People's Bank of China control the issuance of base money and set interest rates that influence the broader money supply. They publish regular reports on currency in circulation, reserve balances, and monetary aggregates. These institutions also manage foreign exchange reserves, which are a form of global money held by governments to stabilize currencies and settle international trade. The IMF's International Financial Statistics provide cross-country comparisons of monetary aggregates here.
Global Wealth Distribution and Rankings
Wealth inequality is tracked by organizations such as Oxfam, Credit Suisse, and the World Inequality Lab, which publish reports on the distribution of global assets and income. The richest individuals and families hold a large share of total wealth, while the majority of the global population holds relatively little. These reports use data from national statistical offices, central banks, and financial disclosures to estimate net worth across countries. Oxfam's latest inequality
