US CPI (Consumer Price Index)

What is the Consumer Price Index (CPI)?

The Consumer Price Index (CPI) is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. It's the most widely used inflation indicator in the United States and serves as the primary gauge for inflation.

How CPI is Calculated

The Bureau of Labor Statistics (BLS) calculates CPI through:

• Market Basket: 80,000+ items across 200+ categories
• Price Collection: 23,000 retail outlets monthly
• Weighting: Based on consumer spending patterns
• Base Period: 1982-1984 = 100

CPI Components

Why CPI Matters for Markets

• Fed Policy: Primary inflation target for monetary policy
• Interest Rates: Influences Federal Reserve rate decisions
• Bond Yields: Affects Treasury yields and yield curve
• Equity Markets: Impacts corporate earnings and valuations
• Cryptocurrency: Influences digital asset valuations and adoption

Federal Reserve Target

The Fed targets 2% annual inflation:

• Above 2%: May lead to rate hikes to cool inflation
• At 2%: Considered price stability achievement
• Below 2%: May prompt stimulative measures

Historical CPI Trends

Notable inflation periods:

• 1970s: Double-digit inflation, peaking at 14.8% in 1980
• 1980s: Volcker disinflation, rates dropped to 3.2%
• 1990s-2000s: Low inflation era, averaging 2.5%
• 2021-2022: Post-COVID inflation surge to 9.1%
• 2023: Disinflation to 3.1%, approaching Fed target
