Inflation Component & Basket Tracker

Overview

This pillar deconstructs headline inflation reports like CPI and PCE into their core components. It separates persistent, slow-moving prices from volatile, fast-moving ones to provide a clearer picture of underlying economic trends.

What It Does

It analyzes the composition of inflation by tracking specific baskets of goods and services. The pillar isolates 'sticky' price inflation, like shelter, from 'flexible' prices, like energy and food. This differentiation helps determine if inflation is a temporary shock or a more entrenched, long-term problem.

Why It Matters

Headline inflation numbers can be misleading. By understanding the drivers, you can better anticipate the Federal Reserve's policy decisions, as they often focus on 'supercore' inflation (services ex-housing) to gauge the persistence of price pressures.

How It Works

First, the pillar ingests monthly CPI and PCE data from official government sources. It then categorizes each line item into predefined baskets, such as sticky, flexible, shelter, and supercore. Finally, it calculates the contribution and momentum of each basket, highlighting which parts of the economy are driving the overall inflation rate.

Methodology

The analysis uses the Atlanta Fed's Sticky-Price CPI methodology to classify components. Supercore inflation is calculated as services less energy services and housing. High-frequency proxies, like the Manheim Used Vehicle Value Index, are used to forecast volatile components ahead of official data releases. Component contributions are weighted according to their share in the respective index.

Edge & Advantage

This pillar provides a forward-looking view by distinguishing lagging indicators like shelter from real-time price changes, helping you anticipate the Fed's reaction before the market consensus forms.

Key Indicators

• Shelter Lag Monitor

  high

  Tracks Owner's Equivalent Rent (OER) and rent prices, which are known to lag real-time market changes by several months.

• Supercore Inflation Index

  high

  Measures services inflation excluding housing and energy, a key metric watched by the Federal Reserve for persistent price pressures.

• Flexible vs. Sticky Price Ratio

  medium

  Compares the inflation rate of items with frequently changing prices (flexible) to those with slow-moving prices (sticky).

Data Sources

• U.S. Bureau of Labor Statistics (BLS)

  Provides the official monthly Consumer Price Index (CPI) data.

• U.S. Bureau of Economic Analysis (BEA)

  Provides the official monthly Personal Consumption Expenditures (PCE) price index data.

• Federal Reserve Bank of Atlanta

  Publishes research and data on Sticky-Price CPI.

Example Questions This Pillar Answers

• → Will the year-over-year Core CPI be over 3.5% on the next release date?
• → Will the Federal Reserve raise, lower, or hold interest rates at the next FOMC meeting?
• → Will the 'Shelter' component of CPI show a month-over-month increase of 0.4% or more?
