Inflation History

This inflation history explorer aggregates official US CPI data into clear charts and tables, making it easy to spot historical trends. It solves the problem of relying on short-term headlines by offering 100+ years of context.

Whether you are researching the Great Depression, the stagflation of the 1970s, or the low-inflation 2010s, this tool provides the long-term perspective you need. It filters out the noise of monthly reports to show the signal of long-term purchasing power changes.

Follow these steps to decode past US inflation patterns.

1. Review the chart: See the year-by-year inflation percentage. Notice the spikes during wars and oil crises.
2. Check averages: Look at the 5-year and 10-year rolling averages to understand the 'era' of inflation (e.g., the high-inflation 80s vs the low-inflation 2000s).
3. Decade Summary: Use the table to see which decades eroded wealth the fastest.

US CPI (Consumer Price Index)

The standard measure of inflation in the United States, compiled by the Bureau of Labor Statistics (BLS). It tracks a basket of goods aimed at the urban consumer.

Stagflation

A period of slow economic growth and relatively high unemployment (stagnation) accompanied by rising prices (inflation). The US experienced this in the 1970s.

Hyperinflation

Extremely rapid inflation. While the US hasn't experienced true hyperinflation, this tool puts our 'high' inflation periods into perspective relative to global events.

Fed Target

The Federal Reserve targets an average inflation rate of 2% over the long run to maintain price stability.

Retirement Stress Testing

The 1970s averaged over 7% inflation. If your retirement plan fails in a 1970s-style scenario, you might need to save more buffer.

Mortgage Rate Context

Current mortgage rates might feel high, but in 1981, 30-year fixed mortgage rates peaked over 18% as the Fed fought inflation. History provides perspective.

Investment Strategy

During the low-inflation 2010s, growth stocks soared. In inflationary periods, value stocks and commodities often perform better. Understanding cycles helps asset allocation.

1. Recency Bias: Thinking the low inflation of the last 10 years is the permanent state of the world. History shows it cycles.
2. Ignoring Volatility: An average of 3% might hide years of -1% and +7%. It's the spikes that hurt cash flow.
3. Confusing Disinflation with Deflation: Disinflation means prices are rising slower (e.g., 5% to 3%). Deflation means prices are actually falling (below 0%).

The CPI basket changes over time to reflect consumer habits (e.g., adding smartphones, removing typewriters). Comparing 1950 CPI to 2024 CPI is imperfect but the best available metric.
