M2 is the Federal Reserve's broadest measure of how much money exists in the U.S. economy. It includes every dollar in your checking account, your savings account, money market funds, and certificates of deposit under $100,000. When someone says "the money supply," they're usually talking about M2.
The Federal Reserve publishes M2 data weekly in its H.6 statistical release. As of early 2026, M2 sits at approximately $22.44 trillion. That number has grown dramatically — it was $15.4 trillion at the start of 2020.
Why M2 matters to your paycheck
Here's the principle: when the money supply grows faster than the economy produces goods and services, each existing dollar loses purchasing power. More dollars chasing the same amount of stuff means each dollar buys less. This is the mechanism behind inflation, and it operates whether CPI measures it accurately or not.
The government's official inflation metric — CPI — currently sits at 2.8% year-over-year. But M2 is growing at 3.9%. That 1.1-point gap represents erosion that shows up in your grocery bill, your rent, and your gas tank before it ever shows up in the official statistics.
The M2 expansion of 2020–2021
Between January 2020 and January 2022, M2 surged from $15.4 trillion to $21.6 trillion — a 40% increase in two years. This was the fastest monetary expansion in U.S. history, driven by pandemic-era stimulus, Federal Reserve bond purchases, and direct fiscal transfers.
The consequences weren't theoretical. By mid-2022, CPI had hit 9.1%, the highest in four decades. But even as CPI has since cooled back toward 3%, the money supply has not contracted proportionally. Those newly created dollars are still in the system, permanently diluting the ones you already had.
How to read M2 data yourself
The Federal Reserve publishes M2 data every Tuesday for the prior week on the FRED (Federal Reserve Economic Data) database. The key metric is the year-over-year percentage change. When this number exceeds GDP growth, purchasing power is eroding. When it exceeds CPI, the official inflation measure is understating the real cost to your wallet.
The gap between M2 growth and CPI is what we call the Debase Score. It measures the erosion that doesn't appear on any government report — or on your pay stub.
What this means for your salary
If M2 is growing at 3.9% and your last raise was 3%, you didn't get a raise. You took a 0.9% pay cut in real purchasing power terms. The math is simple and the consequences compound: each year the gap persists, you fall further behind. Over five years, those fractions add up to thousands of dollars in lost buying power that nobody sends you a bill for.
This is the number the Debase Brief tracks every morning — the gap between what the government says inflation is and what the money supply says it actually is. Use the calculator to see what your specific salary is actually worth after M2 erosion.
