Sahm Rule Recession Indicator
The Sahm Rule, developed by economist Claudia Sahm, measures how far the 3-month average unemployment rate has risen above its lowest point in the prior 12 months. Built to be simple, real-time, and based solely on the unemployment rate, it crosses its threshold the moment a recession likely begins — without waiting on the NBER's lagged official dating.
Latest reading
As of June 2026, Sahm Rule (Sahm Rule indicator) stands at 0.07 — down from 0.10 the prior reading. Below 0.3 means the labor market is healthy with no signal. The 0.3-0.5 zone is elevated and worth watching. At 0.50 the rule triggers — historically a reliable mark that a recession is underway, correct for every US recession since 1970. The speed of the rise matters, and the brief 2024 trip above the line is a reminder to read it alongside other indicators, not in isolation. Series history runs from 1993 to present.
