The US Expansion Is 77 Months Old: What History Says Comes Next

As seen on the 24/7 Wall St. homepage on October 31, 2026.

This cycle has already run 10 months past the postwar average, with 51 months still separating it from the 2009-2020 record. Expansions do not die of old age, but positioning as if this one runs forever is a choice.

The US economy has now been in an expansion for 77 months. Average expansion since 1949: 67 months Longest: 128 months (2009 - 2020) Shortest: 12 months (1980 - 1981) https://t.co/Ekn3ejJxnV

The current expansion has already outlasted the postwar average by 10 months. Since 1949, the average US expansion has run 67 months, meaning this cycle crossed into above-average territory some time ago and is still going.

The record to beat is 128 months, set during the 2009 to 2020 expansion, so this cycle still has historical room to run before it claims the title.

The shortest expansion on record lasted just 12 months, from 1980 to 1981, a reminder that expansions do not follow a predictable clock and age alone tells an investor very little about timing.

The record supports neither positioning for an imminent end nor assuming this expansion keeps going. The read is uncertainty, which is exactly where knowing the historical benchmarks pays off.
