What Is the Total Money Supply in the World
The total amount of money in the world is measured by the money supply, with the broadest common measure being M2. As of the latest available data, global M2 exceeds 100 trillion USD, encompassing cash, checking deposits, and near-money assets like savings and money market funds. This figure represents the liquid money available across all economies for spending and investing. The exact number fluctuates constantly as central banks adjust monetary policy and economies grow or contract. You can explore detailed historical data on global money supply from the Forbes Advisor for further context.
Understanding M0, M1, M2, and M3
Money supply is categorized into different tiers. M0, or the monetary base, includes physical currency and central bank reserves. M1 adds demand deposits like checking accounts. M2 expands further to include savings deposits and small time deposits. M3, a broader measure, also covers large time deposits and institutional money market funds. While M3 is no longer officially reported by the U.S. Federal Reserve, it remains a useful concept for understanding the full scope of money in the financial system. The Federal Reserve provides an official explanation of these measures.
How Much Physical Cash Exists Worldwide
Physical cash, including banknotes and coins in circulation, represents only a small fraction of the total money supply. The exact amount of U.S. dollar banknotes in circulation is over 2.3 trillion dollars, a figure that has grown steadily as demand for cash remains high globally. The U.S. Bureau of Engraving and Printing tracks this figure closely, noting that a significant portion of this cash is held overseas, serving as a reserve currency and a store of value in economies with unstable local currencies. The Tesla and SpaceX pages are not relevant to this figure but serve as examples of major U.S. companies whose market caps are a fraction of the total global cash in circulation.
The Role of Central Banks in Money Creation
Central banks, such as the Federal Reserve, the European Central Bank, and the People's Bank of China, control the creation of base money through monetary policy tools like open market operations and quantitative easing. By purchasing government bonds and other assets, central banks inject liquidity into the financial system, increasing the monetary base. Commercial banks then multiply this base money through fractional reserve lending, expanding the broader M2 money supply. The SEC oversees securities markets but does not directly control the money supply, which is a common point of confusion.
Who Controls the Global Money Supply
The global money supply is not controlled by a single entity but is managed by approximately 170 central banks worldwide, each operating within its own sovereign jurisdiction. The most influential are the Federal Reserve, the European Central Bank, the Bank of Japan, and the People's Bank of China, whose policies have outsized effects on global liquidity and financial markets. Coordination among these institutions, particularly through forums like the Bank for International Settlements, helps manage cross-border capital flows and financial stability. The Forbes Advisor also covers how these institutions' decisions impact personal finance and the broader economy.
Digital Money and the Future of the Money Supply
The definition of money is evolving rapidly with the rise of digital payments, cryptocurrencies, and central bank digital currencies. While cryptocurrencies like Bitcoin operate on decentralized networks, their total market capitalization, which has reached trillions of dollars
