Global monetary value in 2017 reflected a mature financial system nearing recovery from the 2008 crisis. Experts tracked not only cash and deposits but also broad measures such as broad money and liquid instruments to capture the full scale of economic activity.
By combining currency, bank deposits, and near-money assets, analysts estimated the aggregate sum of money available for spending and investment across nations. This overview uses a structured snapshot to clarify how the total was composed and measured in 2017.
| Metric | 2017 Value (USD) | Share of Total | Notes |
|---|---|---|---|
| Physical Currency (Cash) | ~6 trillion | ~5% | Notes and coins in circulation, held by public and banks |
| Bank Deposits (Demand & Savings) | ~27 trillion | ~22% | Retail and corporate deposits in commercial banks |
| Broad Money (M2) Components | ~75 trillion | ~60% | Includes savings, time deposits, and retail money market funds |
| Total Broad Money Supply (M2) | ~120 trillion | ~100% | Approximate global M2, the primary measure of money availability |
| Total Financial Assets (wider scope) | ~150–200 trillion | ~100%+ | Bonds, equities, and other instruments beyond narrow money |
Global Money Supply Measures in 2017
Analysts categorized money using metrics such as M0, M1, M2, and M3 to reflect different levels of liquidity. In 2017, M2 became the most widely reported benchmark, capturing cash, deposits, and short-term liquid instruments. Tracking these measures helped institutions assess inflation risks and monetary policy effectiveness across regions.
Among emerging markets, rapid digitalization began shifting how balances were held, with mobile money and fintech accounts contributing to broader M2 components. Central banks monitored these trends closely to ensure stability while accommodating new payment technologies. By quantifying deposits and near-money instruments, M2 offered a practical view of resources available for spending and investment.
Physical Currency and Central Bank Reserves
Physical currency formed a small but visible slice of global money in 2017, with the majority held outside formal banking systems. Central bank reserves, including gold and foreign exchange, represented another layer of stored value, supporting international trade and confidence in currencies. Together, these stores of value underpinned the broader monetary framework despite their modest share of total financial assets.
High-denomination banknotes played a disproportionate role in cash holdings, especially in regions with limited banking access. Policymakers weighed the benefits of cash inclusion against risks such as illicit activity and reduced seigniorage revenue. The resilience of cash in 2017 highlighted its role as a fallback store of value during periods of financial uncertainty.
Broad Money, Banking, and Financial Depth
Broad money aggregates grew steadily in 2017, driven by higher bank lending, expanding deposit bases, and improved financial inclusion. Commercial banks remained central to money creation, converting central bank liquidity into loans and deposit liabilities. This process amplified the total amount of usable balances beyond the base money issued by authorities.
Disparities across countries were pronounced, with advanced economies showing deeper banking systems and higher per capita deposit volumes. Emerging markets continued to build infrastructure, leveraging technology to lower costs and expand access. Financial depth, measured by deposits relative to GDP, signaled the capacity of economies to fund investment and consumption.
Digital Money, Fintech, and New Instruments
Fintech innovation in 2017 accelerated the inclusion of non-bank balances into the broader money stock. Mobile wallets, e-money accounts, and peer-to-peer platforms allowed users to hold and transfer value without traditional bank accounts. Regulators grappled with how to count these balances while maintaining oversight of systemic risk.
As digital transactions expanded, velocity of money increased, complicating inflation forecasts based on traditional aggregates. Central banks began experimenting with broader definitions that captured stablecoin-like instruments and prepaid digital credits. This evolution underscored the need for adaptable metrics in a rapidly changing payments landscape.

FAQ
Reader questions
How was the total value of money in 2017 calculated across countries?
Researchers aggregated central bank statistics, International Monetary Fund data, and banking reports to compile money supply figures, harmonizing methodologies where possible and using market exchange rates for cross-country comparison.
What portion of the world's money in 2017 was held in digital form versus cash?
The majority of money existed as electronic deposits rather than physical notes, with digital balances comprising roughly 90% or more of broad money, while cash represented a small but culturally significant fraction.
Did money supply growth in 2017 outpace economic growth, and what does that imply?
In many regions, monetary aggregates rose faster than nominal GDP, reflecting accommodative policies and financial deepening, which supported activity but also prompted monitoring of asset prices and debt levels.
How does the composition of money in 2017 compare to earlier decades in terms of stability and risk?
While cash shares declined, the system in 2017 showed improved crisis resilience due to stronger bank capital and better supervision, though new risks from shadow banking and digital currencies began to emerge.
