LFSI: Frequently Asked Questions
Liquidity & Financial Stress Index
The systemic heartbeat of the financial system.
LFSI measures systemic funding stress across the US financial system, combining interbank spreads, commercial paper rates, repo market conditions, and broad credit availability signals into a single normalized composite.
What does the LFSI measure?
The Liquidity & Financial Stress Index (LFSI) measures the overall health of the US financial plumbing — the interbank lending market, short-term funding conditions, and the ease with which financial institutions can access liquidity. A high LFSI reading signals systemic stress; institutions are reluctant to lend to each other, short-term credit is scarce, and the financial system is under strain. A low reading indicates ample liquidity and well-functioning credit markets.
What inputs drive the LFSI?
LFSI combines several key funding market indicators: the TED spread (Treasury bill rate minus 3-month LIBOR/SOFR), the LIBOR-OIS spread (a measure of bank credit risk vs. the overnight risk-free rate), commercial paper spreads, repo market rates relative to the Fed Funds rate, and money market mutual fund flows. Each input is normalized over a rolling window before being aggregated into the composite.
What LFSI level signals financial stress?
MarketSchema classifies LFSI readings above 60 as 'Elevated Stress,' indicating funding markets are under material strain. Readings above 80 have historically corresponded to acute crisis conditions (2008 financial crisis, March 2020 pandemic shock, October 2022 UK gilt crisis). Readings below 30 indicate loose liquidity conditions — historically associated with risk-on environments and compressed credit spreads.
How does LFSI differ from the CRSI?
LFSI focuses on funding markets — the plumbing of the financial system — while CRSI (Credit Spread Intensity) focuses on credit risk pricing in corporate bond markets. LFSI spikes when banks stop trusting each other; CRSI spikes when investors demand higher compensation for corporate default risk. They often move together during crises, but can diverge during periods of credit stress that haven't yet infected interbank funding (or vice versa). When both are elevated, the signal is highly reliable.
Can LFSI be a leading indicator?
Yes — LFSI tends to lead broader market stress events because funding market dislocations often precede visible price movements in equities and credit. Historically, sustained LFSI readings above 55 for 2+ weeks have preceded significant risk-off moves in equities by 2-6 weeks in roughly 70% of instances over the past 20 years. However, it can produce false positives during periods of technical funding pressure that don't reflect underlying economic stress.
Why does LFSI matter for non-financial investors?
Funding stress in the financial system affects all asset classes because financial institutions are the transmission mechanism for credit to the real economy. When LFSI is elevated, bank lending tightens, corporate credit conditions worsen, and the probability of a broader economic slowdown increases. Equity investors should track LFSI as a leading indicator of credit tightening cycles. Bond investors should watch it for spread widening signals across IG and HY markets.
