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

A liquidity index for studying changes in financial liquidity and comparing its trajectory with asset-price changes, using separately defined weekly and monthly variants.
Important qualification: Weekly and monthly FLI are not interchangeable observations or a simple resampling of one series.
