There's a persistent gap between how fast the Federal Reserve is creating money and how fast the government says prices are rising. This gap isn't a conspiracy — it's a measurement difference with real consequences for your wallet. M2 measures the cause (money creation). CPI measures the effect (price changes). The cause consistently runs ahead of the effect.
Why the gap exists
When the Federal Reserve expands the money supply, those new dollars don't hit consumer prices immediately. They flow first into financial assets — stocks, bonds, real estate — before gradually filtering into the broader economy. This lag can be months or years. CPI captures the end of this process. M2 captures the beginning. The gap between them is the inflation that's already been created but hasn't fully arrived yet.
Think of it like water behind a dam. M2 measures the rising water level. CPI measures how much is flowing over the spillway. The water level is always higher than the flow. That difference is the pressure building behind the dam — and it's the pressure building against your purchasing power.
Historical pattern: M2 leads, CPI follows
This isn't theoretical. In 2020-2021, M2 surged by over 25% in a single year. CPI didn't spike until mid-2021 and didn't peak until June 2022 at 9.1%. The lag was roughly 12-18 months. The people who watched M2 saw inflation coming. The people who watched CPI were surprised.
Today the gap is smaller — 1.1 points — but the pattern continues. M2 is growing again after briefly contracting in 2023, and CPI remains below that growth rate. The gap is the unreported erosion happening right now, building pressure that will eventually show up in prices, in your rent, in your grocery bill.
What the gap means for your raise
Most companies benchmark raises against CPI. If CPI says 2.8%, a 3% raise looks generous. But if M2 says the real erosion rate is 3.9%, that "generous" raise is actually a 0.9% pay cut. The M2-CPI gap is the exact amount by which CPI-benchmarked raises systematically underpay workers relative to actual monetary erosion.
This gap is what the Debase Score tracks. It's the silent erosion rate — the purchasing power loss that's real but unreported. We calculate it fresh every morning from verified government data.
Over a career, the compounding effect of this gap is substantial. A worker receiving CPI-matched raises for 20 years while M2 consistently exceeds CPI by 1-2 points will lose the equivalent of several years' worth of purchasing power — without ever seeing a pay cut on paper.
