Economic Context: The 1940s Era
World War II dominated the 1940s economy. Price controls were implemented during the war, but once lifted, pent-up demand drove prices sharply higher in the late 1940s.

How to Beat Inflation
With an average annual inflation rate of 3.74% since 1940, simply keeping cash in a savings account would have resulted in a significant loss of purchasing power. Here are strategies that have historically outpaced inflation:
S&P 500 Index Funds
Historically returning ~10% annually before inflation, the stock market has been one of the most reliable ways to grow wealth beyond inflation. Even accounting for downturns, long-term investors who stayed the course have seen real returns of approximately 7% per year.
Real Estate
Property values have historically appreciated at rates exceeding inflation, averaging 3-5% annually plus rental income. Real estate also provides a natural inflation hedge since rents and property values tend to rise with the general price level.
I-Bonds & TIPS
Treasury Inflation-Protected Securities (TIPS) and Series I Savings Bonds are specifically designed to keep pace with inflation. Their principal adjusts with the CPI, guaranteeing your investment maintains its purchasing power.
Dividend Growth Stocks
Companies that consistently increase their dividends — known as Dividend Aristocrats — have historically outpaced inflation. Many have raised dividends for 25+ consecutive years, providing a growing income stream that offsets rising costs.
Frequently Asked Questions
What is inflation?▼
Inflation is the rate at which the general level of prices for goods and services rises over time, causing purchasing power to fall. It is measured using the Consumer Price Index (CPI), which tracks the average price change paid by urban consumers for a basket of goods and services.
How is the CPI calculated?▼
The Bureau of Labor Statistics (BLS) calculates the CPI by tracking the prices of approximately 80,000 items in 75 urban areas across the country. The index measures price changes from a reference base period (1982-84 = 100) across categories including food, housing, transportation, medical care, and education.
What causes inflation?▼
Inflation can be caused by demand-pull factors (too much money chasing too few goods), cost-push factors (rising production costs passed to consumers), or monetary policy (central banks increasing the money supply). Major events like supply chain disruptions, energy crises, and fiscal stimulus can also drive inflation.
How can I protect my savings from inflation?▼
To protect your savings from inflation, consider investing in assets that historically outpace inflation: stock index funds (averaging ~10% annually), real estate, Treasury Inflation-Protected Securities (TIPS), I-Bonds, and commodities. Keeping all your money in a standard savings account virtually guarantees a loss of purchasing power over time.
What is the current inflation rate?▼
As of early 2026, the annual inflation rate is approximately 2.5-3%, moderating from the highs of 2022 when inflation exceeded 9%. The Federal Reserve targets a 2% annual inflation rate as its long-term goal.
