Sahm Rule Recession Indicator & Unemployment Threshold

Real-time macroeconomic risk modeling outlined on our recession signal intelligence portal relies heavily on the sahm rule recession indicator unemployment rate threshold. Formulated by former Federal Reserve economist Claudia Sahm, this empirical metric identifies the onset of an economic contraction with zero false positives since 1970.

The indicator triggers when the 3-month moving average of the national unemployment rate (U3) rises by 0.50 percentage points or more above its minimum 3-month average during the prior 12 months. Because labor market decelerations are non-linear, small increases in joblessness historically trigger negative feedback loops of reduced consumer spending, declining corporate revenues, and secondary layoff waves.

While immigration surges and temporary labor supply expansions can occasionally distort headline unemployment metrics, triggering the Sahm Rule forces algorithmic asset allocators to trim cyclical equity exposures and increase duration positioning across sovereign debt.
