STLFSI Weekly Change graph

Over the past week, 10 of the 18 indicators contributed negatively to the change in the index, the same number as in the previous week. As in the previous week, the largest negative contributions were made by the yield difference between the three-month commercial paper rate and the three-month Treasury bill (CPS_3mo) and the yield spread between the Merrill Lynch High-Yield Corporate Master II Index and the 10-year U.S. Treasury (HighYield_CRS). Five of the 18 indicators contributed positively to the weekly change in the index, also the same number as the previous week. The two largest positive contributions were from the Chicago Board Options Exchange Market Volatility Index (VIX) and expected inflation rate over the next 10 years (BIR_10yr).

The St. Louis Fed Financial Stress Index (STLFSI)

Link to STLFSI in FRED

The STLFSI measures the degree of financial stress in the markets and is constructed from 18 weekly data series: seven interest rate series, six yield spreads and five other indicators. Each of these variables captures some aspect of financial stress. Accordingly, as the level of financial stress in the economy changes, the data series are likely to move together.

How to interpret the index
The average value of the index, which begins in late 1993, is designed to be zero. Thus, zero is viewed as representing normal financial market conditions. Values below zero suggest below-average financial market stress, while values above zero suggest above-average financial market stress.

Note that the bar charts plot the change in the contribution from one week to the next or from the current week compared to the value 52 weeks earlier.

More information
