What Counts as Money in Global Figures
Money in the world is measured by layers called monetary aggregates, which capture cash, bank deposits, and near-money instruments. The narrowest layer, M0, covers physical notes and coins plus bank reserves, while broader layers add checking accounts, savings, and money market funds. Central banks and the Bank for International Settlements publish these figures, and the International Monetary Fund tracks cross-country comparisons in its Financial Soundness Indicators.
As of the latest available data, global M0 stands around 10 trillion U.S. dollars, while M2 across reporting economies exceeds 100 trillion U.S. dollars, reflecting the dominance of digital bank money over physical cash. The Federal Reserve, European Central Bank, and People's Bank of China together hold the largest shares of base money, and their balance sheet sizes directly shape the global money stock.
How Much Physical Cash Exists Worldwide
Physical cash in circulation is a small fraction of total money, yet it remains the most tangible measure of how much money is in the world. U.S. dollar bills dominate global holdings, with the Federal Reserve noting that the value of Federal Reserve notes in circulation has grown steadily, reaching over 2 trillion U.S. dollars in recent years, driven by both domestic use and international demand as a store of value.
Outside the United States, the euro and Chinese yuan account for large shares of physical notes, while the Japanese yen and British pound also contribute meaningfully. The BIS and national central banks publish annual data on banknote circulation, and the rise of high-denomination notes in some regions reflects demand for portable, anonymous value.
Top Currencies by Cash in Circulation
U.S. Dollar
The U.S. dollar remains the most widely held currency globally, with Federal Reserve data showing that a significant portion of U.S. notes circulate outside the United States, especially in emerging markets and regions with unstable local currencies.
Euro
The European Central Bank reports that euro banknotes in circulation have grown in value over the past decade, with the 50 and 100 euro notes accounting for a large share of the total face value.
Chinese Yuan
China's central bank tracks renminbi cash in circulation, which has expanded as the economy grew, though digital payments have reduced the relative share of physical notes within the country.
Broad Money Supply and Digital Money
Broad money, often labeled M2 or M3, includes savings deposits, time deposits, and money market funds, and it represents the most comprehensive public measure of how much money is in the world. The IMF's International Financial Statistics and the Bank for International Settlements compile these figures across countries, showing that advanced economies typically have M2-to-GDP ratios above 100 percent, while emerging markets vary widely depending on financial depth and dollarization.
Digital money has transformed the composition of the money supply, with commercial bank deposits now forming the largest component of broad money in most nations. Fintech firms, payment networks, and central bank digital currency projects are reshaping how money moves, and the Financial Stability Board monitors these shifts to assess systemic risk and liquidity conditions globally.
Money, Credit, and Financial Stability
Credit creation by banks is closely tied to the money supply, as new loans generate new deposits, expanding broad money beyond the base money issued by central banks. The Bank for International Settlements tracks bank credit to the non-financial sector, and the Financial Stability Board publishes indicators that link money growth to leverage and vulnerability in the global financial system.
