100 years of inflation, rates and debt — the long run

Inflation, interest rates, recessions and federal debt across a full century, plus by-president and by-decade tables. The long view is the antidote to headline myopia: double-digit 1970s inflation, the Volcker squeeze, the 2010s lowflation decade and the 2021-22 spike all on one axis.

Live readings

Every era's "unprecedented" inflation had precedent. The tables slice the same data by presidential term and by decade — useful context, though monetary policy, wars and oil shocks respect no political calendar.

What this page measures

Annual averages of the seven series that define a macro era — CPI inflation, the fed funds rate, the 10-year Treasury yield, the 30-year mortgage rate, unemployment, federal debt to GDP and M2 growth — drawn from the Federal Reserve's archive on one axis, from 1914 to 2025. The long view is the antidote to headline myopia: every era's "unprecedented" inflation had precedent.

Inflation by decade — average of the annual rates

1910s 10.0% (6 years), 1920s 0.1%, 1930s -2.0%, 1940s 5.6%, 1950s 2.1%, 1960s 2.3%, 1970s 7.1%, 1980s 5.6%, 1990s 3.0%, 2000s 2.6%, 2010s 1.8%, 2020s 3.9% (6 years).

The shape is the story: the two wars and their aftermaths, the 1970s (oil embargoes on top of an economy already running hot, ending in the Volcker squeeze of 1979–82), the great moderation, the 2010s lowflation decade when the fed funds rate sat at zero for seven years, and the 2021–22 spike. Today's Gauge of 3.45% and official CPI of 3.7% sit against that record, not against the last five years.

Each calendar year counts for one president only: the one in office for most of that year, so an inauguration year goes to the incoming president. Debt to GDP from the last quarter completed before the term began to the last quarter completed before it ended. It is left blank for the term in progress. The quarterly debt series starts in 1966. The highest average inflation over a completed term: Woodrow Wilson 10.85%, Jimmy Carter 9.73%, Gerald Ford 7.44%; the lowest: Herbert Hoover -5.47%, Warren Harding -5.10%, Calvin Coolidge 0.14%. Useful context, with the caveat the page states: monetary policy, wars and oil shocks respect no political calendar, and the Fed, not the White House, sets the policy rate.

Sources and construction

BLS CPI-U (1913 onward; annual inflation is the change in the annual-average index from the year before, the way BLS computes it; 2025's annual average covers 11 months: no October 2025 CPI was published); Federal Reserve fed funds (1954 onward) and the long-term Treasury composite (1925–1961) spliced with the 10-year constant-maturity yield; Freddie Mac mortgage rates (1971 onward); BLS unemployment (1948 onward; 2025's annual average covers 11 months: no October 2025 unemployment rate was published); total public debt to GDP from the Office of Management and Budget and the St. Louis Fed (quarterly, 1966 onward); Fed M2 (1960 onward). Availability varies by series and the page charts only what is official; nothing is interpolated.

Terms on this page

Annual average
The mean of the monthly values of a year. Annual inflation is the change from one year's average index to the next, not December over December.
Debt to GDP
Total public debt, which is debt held by the public plus debt held by federal trust funds such as Social Security, as a share of nominal GDP (FRED series GFDEGDQ188S).
Constant-maturity yield
The Treasury yield interpolated to an exact maturity (here ten years) from the traded curve, published daily by the Fed.
