Why it matters
The monthly change is the freshest reading of price pressure: the yearly rate is the sum of the last twelve monthly changes, so today's monthly figure tells you where the yearly rate is heading.
How it is calculated
the Bureau of Labor Statistics (prices and jobs), the Bureau of Economic Analysis (GDP, income and spending) and the Census Bureau (retail sales, housing, trade) prices a fixed basket of goods and services across the country and compares the index with the previous period. Seasonal patterns (sales, holidays) make raw monthly figures jumpy; some countries also publish seasonally adjusted numbers.
Monthly inflation = index(this month) ÷ index(last month) − 1
Annualised ≈ (1 + monthly)¹² − 1What changes mean
- Compare with the same month in earlier years: January and September often have seasonal jumps.
- 0.2% a month is about the 2% a year most central banks aim for.
Higher than expected: A higher figure than expected makes the Federal Reserve more likely to keep rates high or raise them: it tends to support the US dollar and push bond yields up, and is often a weight on stocks.
Lower than expected: A lower figure than expected gives the Federal Reserve room to cut or hold rates lower: the US dollar tends to soften and bond yields to fall.
A short history
Monthly price indexes date from the early 20th century; many countries began publishing them during or after the First World War to adjust wages to the cost of living.
