How much money is in the world? A complete breakdown

Ever wondered how much money exists in the world? The answer is more complex than you might think. Between cash, bank deposits, investments, and digital currencies, the total amount of money in circulation is always changing. Let's break it down.
What counts as money?
Money isn’t just the cash in your wallet. It comes in different forms based on how easily it can be spent or accessed. Economists group money into categories to help track its availability and use. Think of it like layers:
M0 (physical money): This is the most basic form — cash and coins you can hold in your hand.
M1 (instant access money): This includes M0 plus the money in checking accounts, ready to be spent anytime.
M2 (broad money): Expands on M1 by adding savings accounts and money market funds, which aren’t instantly available but can be accessed fairly quickly.
M3 (widest money definition): The broadest category, including M2 plus larger deposits and institutional funds that move more slowly but still contribute to the economy.
How much money is in the world?
Estimating the total money supply is challenging because different countries define and report their money differently. However, experts approximate global money supply using data from major economies like the U.S., China, the Eurozone, Japan, and the U.K.
Here’s what recent estimates suggest:
M0 (cash and coins): Around $8 trillion worldwide.
M1 (cash + checking deposits): Roughly $50 trillion.
M2 (including savings & money markets): Over $90 trillion.
M3 (widest financial assets): Well over $130 trillion.
These numbers come from sources like the U.S. Federal Reserve, European Central Bank, People’s Bank of China, and other major financial institutions. Since different countries define money slightly differently, these estimates are always approximate.
Why is it hard to measure global money supply?
Unlike counting the cash in your pocket, calculating the world’s total money supply is tricky. Here’s why:
Different definitions: Countries use slightly different criteria for M0, M1, M2, and M3.
Currency fluctuations: Exchange rates impact how we compare money across nations.
Reporting lags: Some central banks update their money supply figures monthly, while others do so less frequently.
No single data source: Organizations like the International Monetary Fund (IMF) and Bank for International Settlements (BIS) compile reports, but no one entity publishes a universal, real-time figure.
The rise of digital money
Beyond traditional banking, digital currencies like Bitcoin and Ethereum are making an impact. The cryptocurrency market alone is valued at just under $3 trillion, although this constantly fluctuates. Though volatile, these assets are reshaping financial systems worldwide.
How much money is there per person?
With the world population surpassing 8 billion, dividing the estimated global money supply gives a rough idea of money per person:
If we consider M1 (~$50 trillion), that’s about $6,250 per person.
Expanding to M2 (~$90 trillion), each person theoretically has $11,250.
Looking at M3 (~$130 trillion+), the figure rises to $16,250 per person.
Of course, money isn't distributed evenly, which is why understanding financial literacy and responsible money management is important.
Why this matters for families
Knowing how money works on a global scale helps kids and parents appreciate financial systems and personal finance. Teaching children about different forms of money — from cash to digital wallets — can help set them up for success in an increasingly cashless world.
