NBER Recession Watch

The official US business cycle chronology from the National Bureau of Economic Research, plus FRED's USREC monthly indicator. The canonical "ground truth" for recession dating — and famously slow to publish (median 7-month peak announcement lag, 15-month trough). Updated .

NBER's Business Cycle Dating Committee declares peaks and troughs only after extensive deliberation — protecting against false recessions, at the cost of late confirmation. The BCI nowcast on the dashboard exists precisely because of this lag: real-time risk management can't wait 7-15 months for NBER to confirm. This page surfaces NBER's view as the reference benchmark; the BCI-based regime calls live elsewhere.

Current state

USREC indicator history (1950 onwards)

USREC = NBER's monthly recession indicator (1 in recession, 0 in expansion). Shaded bands mark each recession period. Since 1950 the US has had NBER-dated recessions. The current expansion (started ) is on its ᵗʰ month — long by historical standards.

NBER chronology — every modern recession with its announcement lag

Why the announcement lag matters

The lag is the whole problem

Median NBER peak announcement comes months after the recession actually starts. By the time NBER says "we're in a recession," the equity-market drawdown has typically already happened (median S&P peak-to-trough of past 4 recessions: −34%). Real-time risk management can't wait. The BCI nowcast and recession-ensemble probabilities exist exactly to cover this gap.

When NBER does call it, it's right

Despite the lag, NBER's record is essentially perfect — every modern US recession was correctly dated, and there are zero "false positive" recession declarations. The committee deliberates until the data is unambiguous. NBER's role is the ex-post benchmark; nowcasts measure themselves against this ground truth.

Most recent recession (for context)

peak → trough. Duration months. Peak announced (-month lag). Trough announced (-month lag). The COVID recession was the shortest and most severe in the modern record — and the trough announcement lagged 15 months, fairly typical despite the unusual cycle shape.
