Consumer Price Index (CPI) — Year-over-Year vs M2 Money Supply (Year-over-Year Change)

What Consumer Price Index (CPI) — Year-over-Year measures

The Consumer Price Index measures the average change over time in the prices paid by urban consumers for a basket of goods and services. The year-over-year change is the most commonly cited measure of inflation.

Inflation at 2.8% remains above the Federal Reserve's 2% target but has moderated significantly from the 2022 peak of 9.1%. For executives, this means input costs are still rising faster than the Fed's comfort zone, but the pricing environment is stabilizing. Companies with strong pricing power can pass through cost increases; those in competitive markets face margin pressure. The Fed is unlikely to cut rates aggressively until CPI moves closer to 2%.

What M2 Money Supply (Year-over-Year Change) measures

M2 is a measure of the money supply that includes cash, checking deposits, savings deposits, money market funds, and small time deposits. Year-over-year changes in M2 are a leading indicator of inflation and economic activity.

M2 growth has recovered to 3.9% year-over-year after an unprecedented contraction in 2023 (the first in modern history). The normalization of money supply growth supports economic activity without being excessively inflationary. For executives, moderate M2 growth (3-5%) is consistent with a healthy economy — it means enough liquidity to support business activity without fueling the kind of excess that drove 2021-2022 inflation.
