U.S. recessions · Source: NBER

Index score (0–100) · 1916-03-01–2026-10-01 · 1,328 observations. Snapshot retrieved 2026-10-30. Monthly reconstructed/current-revision history. Regime levels and changes answer separate research questions.

Recession shading uses NBER’s monthly convention: the month after a peak through the trough month, inclusive. Dates are determined retrospectively and are not contemporaneous signals. Historical snapshot, not a live feed or an archive of originally published vintages. Earlier observations may be reconstructed or revised; original publication timestamps have not been verified. These plots do not establish historical tradability, predictive performance or causation. Weekly FLI has its own scale and is not interchangeable with monthly FLI. GFC is plotted on its observation dates without a forward shift. Display does not grant a redistribution license.

Research applications

Liquidity-cycle monitoring, historical regime research, cross-asset context.

A bounded liquidity-regime score for classifying the state of the financial-liquidity cycle and studying changes within it.

Important qualification: Long-run reconstructed observations must not be confused with an archive of real-time publications.
