The Measure of the Money Stock Called M1 Includes

When economists and policymakers discuss the health of an economy, they often refer to the money supply, but few people stop to consider exactly what counts as money. The measure of the money stock called m1 includes the most liquid assets available in an economy, representing the cash and near-cash resources that individuals and businesses can spend immediately. Understanding this definition is crucial because it forms the foundation for analyzing inflation, interest rates, and overall economic activity. Still, while many people assume money only means physical bills and coins, the reality is far more nuanced. This guide breaks down exactly what constitutes M1, why these specific assets are chosen, and how they differ from broader measures of money in circulation That alone is useful..

What Is the Money

What Is the Money Supply?

At its core, the money supply is the total stock of currency and other liquid instruments circulating in a country’s economy at a specific point in time. Day to day, the supply is categorized into a hierarchy of aggregates—typically labeled M0, M1, M2, and sometimes M3—ranked by their degree of liquidity, or how quickly and easily an asset can be converted into spendable cash without significant loss of value. Central banks, such as the Federal Reserve in the United States, monitor and manage this supply through monetary policy to achieve macroeconomic goals like price stability and maximum employment. M1 sits at the top of this hierarchy as the narrowest and most liquid measure, capturing only those assets that function directly as a medium of exchange And it works..

The Core Components of M1

The measure of the money stock called M1 includes four distinct categories, each representing a claim on goods and services that can be exercised instantly No workaround needed..

1. Currency in Circulation

This is the most tangible component, consisting of Federal Reserve notes (paper bills) and U.S. Treasury coins held by the public. Crucially, it excludes cash held in the vaults of depository institutions (bank reserves) and cash held by the U.S. Treasury or the Federal Reserve Banks themselves. Only currency actively circulating in the hands of households and businesses qualifies, as this represents immediate purchasing power The details matter here..

2. Demand Deposits

These are balances held in commercial bank accounts from which the depositor can withdraw funds on demand without prior notice or penalty—most commonly, standard checking accounts. Because funds can be accessed via checks, debit cards, ATMs, or electronic transfers instantly, these deposits function as perfect substitutes for physical cash in nearly all transactions Worth keeping that in mind..

3. Other Liquid Deposits (Including NOW and ATS Accounts)

This category captures interest-bearing accounts that retain full checking privileges Simple, but easy to overlook..

• NOW (Negotiable Order of Withdrawal) Accounts: Interest-bearing checking accounts offered by commercial banks, savings banks, and credit unions.
• ATS (Automatic Transfer Service) Accounts: Savings accounts from which funds are automatically transferred to a checking account to cover checks written or to maintain a minimum balance.
• Share Draft Accounts: The credit union equivalent of checking accounts.
• Demand Deposits at Thrifts: Transaction accounts held at savings and loan associations and mutual savings banks.

4. Traveler’s Checks

Once a staple of international travel, these are pre-printed, fixed-denomination checks issued by non-bank financial institutions (like American Express) that function as cash equivalents. While their usage has plummeted in the era of global ATM networks and credit cards, they remain a component of M1 because they are a direct liability of the issuer payable on demand to the bearer Which is the point..

The May 2020 Redefinition: A Critical Shift

For decades, M1 excluded savings deposits and money market deposit accounts (MMDAs) due to regulatory restrictions—specifically Federal Reserve Regulation D, which limited convenient withdrawals from these accounts to six per month. This distinction created a hard line between M1 (transaction accounts) and M2 (transaction accounts plus savings/small time deposits) Practical, not theoretical..

In April 2020, the Federal Reserve Board announced an interim final rule suspending the six-transfer limit on savings deposits to support banking system liquidity during the COVID-19 pandemic. So naturally, in May 2020, the Fed redefined M1 to include "Other Liquid Deposits," effectively absorbing the bulk of what was previously classified strictly as M2 savings deposits. This change caused a massive, structural spike in the reported M1 figure—jumping from roughly $4 trillion to over $16 trillion virtually overnight—not because new money was printed, but because the definition of "liquidity" had officially expanded to match the new regulatory reality.

M1 vs. M2: Understanding the Distinction

The primary difference between M1 and M2 lies in the immediacy of access.

• M1 (Narrow Money): Assets spendable right now. Cash, checking balances, and instantly accessible interest-bearing accounts. It is the "wallet" measure.
• M2 (Broad Money): M1 plus "near money." This includes savings deposits (even those without checking privileges), small-denomination time deposits (Certificates of Deposit under $100,000), and retail money market mutual fund shares. These assets are highly liquid but typically require a small step—like a transfer, a waiting period, or a penalty for early withdrawal—before they can be spent.

Economists watch M1 for signals on immediate transaction velocity and short-term inflationary pressure, while M2 is often viewed as a better indicator of overall liquidity conditions and potential future spending capacity Not complicated — just consistent..

Why M1 Matters for Policy and Markets

The M1 aggregate is more than an accounting identity; it is a primary input for monetary policy transmission.

1. Inflation Signaling: Rapid growth in M1 relative to real output (GDP) suggests an excess of spending power chasing too few goods, a classic precursor to inflation. The dramatic post-2020 expansion of M1 (driven by both the redefinition and massive fiscal/monetary stimulus) was closely watched as a leading indicator of the inflationary surge that peaked in 2022.
2. Velocity of Money: The ratio

The Ratio that Connects Money and Activity

The velocity of money (V) is the simplest way to gauge how quickly the dollars in M1 circulate through the economy. It is calculated as:

[ V_{M1} = \frac{\text{GDP}}{\text{M1}} ]

When V is high, each dollar is being used many times to purchase goods and services, implying dependable spending and, often, upward pressure on prices. Conversely, a low V suggests that money is sitting idle—perhaps in balances that are technically “liquid” but not yet being spent Simple, but easy to overlook..

Recent Trends in M1 Velocity

*Q1 2024 estimate (BEA preliminary release).

The table shows a steady decline in V_M1 despite the massive expansion of M1 after the 2020 redefinition. The paradox is explained by three interlocking factors:

1. Excess Liquidity in “Savings‑like” Accounts – Even after the redefinition, a sizable share of the newly classified “Other Liquid Deposits” remained in balances that households chose to keep untouched, effectively converting the broader M1 into a de‑facto savings vehicle.
2. Fiscal Transfer Lag – The surge in M1 was driven largely by direct stimulus payments and expanded unemployment benefits. Those funds entered the banking system in 2020‑2021, but many were earmarked for specific expenses (rent, utilities, debt repayment) rather than discretionary consumption.
3. Monetary Policy Response – The Federal Reserve kept the policy rate near zero through most of 2021 and only began a aggressive tightening cycle in early 2022. Low rates reduced the opportunity cost of holding cash, reinforcing the “hold‑onto‑money” behavior.

What the Falling Velocity Means for Policymakers

Market Participants’ Takeaway

• Equities – When V is low, earnings growth is often driven more by valuation expansion than by sales momentum. Investors watch for any signs that V might rise (e.g., a shift from savings to consumption) as a potential catalyst for earnings‑driven rallies.
• Bond Markets – The relationship between M1 growth and nominal yields has weakened in the low‑velocity environment. On the flip side, a sudden uptick in V can re‑ignite inflation expectations, pushing yields higher and reshaping the yield curve.
• Commodities – Precious metals and real assets are often viewed as hedges against future inflation spikes that could accompany a V rebound. Traders monitor M1‑velocity forecasts as part of their macro‑overlay models.

Looking Ahead: The New Money‑Velocity Paradigm

The post‑2020 episode has introduced a structural shift in how we interpret money aggregates:

1. Definition‑Driven Volatility – The 2020 redefinition shows that changes in classification can create headline‑level swings without any real economic activity. Analysts now treat month‑over‑month M1 changes with a healthy dose of skepticism, looking through the “accounting noise.”
2. Hybrid Liquidity – The line between M

The New Money‑Velocity Paradigm (continued)

1. Hybrid Liquidity – Beyond the Traditional M‑Aggregates

The post‑2020 redefinition of M1 highlighted a hybrid nature of money that blends traditional cash‑like assets with near‑money instruments:

You'll probably want to bookmark this section That's the part that actually makes a difference. Turns out it matters..

Because velocity now depends on the mix of these assets, a simple M1‑to‑M2 ratio no longer captures the speed at which purchasing power circulates. Analysts therefore supplement the classic aggregates with “effective velocity” indices that weight each component by its transaction frequency and ease of conversion into spendable funds.

2. Revised Policy Framework

Given the hybrid landscape, the Federal Reserve and other authorities are experimenting with more granular policy levers:

This is the bit that actually matters in practice.

These tools aim to smooth the transmission of monetary policy in an environment where money can sit idle in high‑interest‑bearing savings or flow instantly through digital channels It's one of those things that adds up. Simple as that..

3. Scenario Outlook

4. Conclusion

The prolonged period of low money‑velocity, underscored by the 2020 redefinition of M1, has re‑engineered the relationship between monetary aggregates and economic activity. Policymakers can no longer rely on a single, headline‑driven metric; instead, they must monitor a portfolio of liquidity measures, understand how households and firms allocate their cash‑like holdings, and employ a mix of conventional and targeted levers to steer the economy toward price stability.

In practice, this means:

• Greater data granularity – tracking not just M1 growth but also the composition of near‑money assets and their transaction frequencies.
• More nuanced communication – using “effective velocity” language to keep markets grounded in the underlying speed of spending.
• Flexible toolkits – adjusting reserve requirements, offering incentives for rapid asset turnover, and applying macro‑prudential caps where needed.

By integrating these refinements into their policy arsenal, central banks can mitigate the risk of abrupt inflation spikes while preserving the accommodative stance that has supported growth. The new money‑velocity paradigm, therefore, does not signal a breakdown of monetary transmission; rather, it calls for a more sophisticated, data‑driven approach that reflects the modern, hybrid nature of money in the digital age.
