What Happens When the Leading Economic Index Turns Negative?
The Leading Economic Index anticipates recessions by 6-12 months. What happens when its six-month change turns negative, warning of contraction ahead?

The Mechanics
The St Louis Fed's Leading Economic Index (USSLIND) aggregates forward-looking indicators: yield curve, stock prices, building permits, initial claims, manufacturing orders, and consumer expectations. The six-month annualized change is the most reliable recession signal: a decline below negative 2% has preceded every US recession since 1960 with a median lead time of six months.
Unlike coincident indicators (GDP, employment), leading indicators capture expectations and forward commitments. When permits fall, construction slows 3-6 months later. When orders drop, production slows within a quarter. When the yield curve inverts, credit contracts over 12-24 months. Aggregating these channels into one index dampens noise and captures broad-based weakening.
The Conference Board LEI and St Louis Fed LEI usually move together, but their methodologies differ. The St Louis version uses a factor-model approach drawing on fewer but cleaner financial variables, while the Conference Board version incorporates more consumer and industrial survey data. Divergences between them can reveal whether financial or real-economy channels are driving the signal.
Historical Context
USSLIND six-month changes below -2% have preceded each recession since 1970. The 1973-1975 recession saw the LEI turn negative in late 1973 with peak six-month declines of -5%. The 1980-1982 double-dip produced two separate LEI collapses. The 2001 recession was preceded by LEI turning negative in early 2000. The 2008 recession showed LEI turning negative in December 2007, the exact month the recession began. The 2022-2023 period saw LEI turn negative for over 20 consecutive months without triggering a formal recession, the longest such streak on record and a reason some economists questioned the indicator's continuing reliability in the post-COVID economy.
Market Impact
LEI turning negative historically precedes 10-25% equity drawdowns over the following 6-12 months. The most severe outcomes pair LEI declines with credit-spread widening.
LEI negative turns coincide with the Fed preparing to cut. TLT typically rallies 10-20% as markets price the easing cycle.
Small caps are more sensitive to credit tightening and domestic demand weakness. IWM typically underperforms SPY by 500-1500 bps in the 12 months following LEI turning sharply negative.
Industrials (XLI), materials, and consumer discretionary (XLY) underperform defensive sectors by wide margins. The rotation often begins before LEI turns negative but accelerates on confirmation.
Gold typically outperforms as real yields fall. The gold-to-S&P ratio often marks major lows when LEI first turns negative.
Initial DXY strength from flight-to-quality flows, then weakness as Fed easing widens policy differentials against foreign central banks.
What to Watch For
- -Six-month LEI change below negative 3% annualized
- -Credit spreads widening above 500 bps confirming the LEI signal
- -Yield curve un-inverting (bull steepener)
- -ISM Manufacturing falling below 45 confirming broad-based weakness
- -Continuing claims rising above 2.0 million confirming labor deterioration
How to Interpret Current Conditions
Track USSLIND and its six-month annualized change monthly. Compare against the Conference Board LEI and the Convex Recession Index for convergence or divergence. LEI weakness alongside tightening credit spreads is the most concerning combination, while LEI weakness with credit spreads still tight often produces the false-signal scenarios (2022-2023).

Frequently Asked Questions
What triggers the "the Leading Economic Index Turns Negative" scenario?▾
The scenario activates when six-month change turns negative 2% or worse. The trigger metric and its current reading are shown on this page, so the live state of the scenario is always visible rather than abstract. Convex tracks this trigger continuously and flags crossings within hours.
Which assets are most affected when this scenario unfolds?▾
The Market Impact section lists the full asset-by-asset response, but the primary affected assets include: US Equities (S&P 500), Treasury Bonds (TLT), Small Caps (IWM), Cyclical Sectors. Each asset has historically shown a characteristic pattern of response that is described in detail on the per-asset deep-dive pages linked below.
How often has this scenario played out historically?▾
USSLIND six-month changes below -2% have preceded each recession since 1970. The 1973-1975 recession saw the LEI turn negative in late 1973 with peak six-month declines of -5%. The 1980-1982 double-dip produced two separate LEI collapses. The 2001 recession was preceded by LEI turning negative in early 2000. The 2008 recession showed LEI turning negative in December 2007, the exact month the recession began. The 2022-2023 period saw LEI turn negative for over 20 consecutive months without triggering a formal recession, the longest such streak on record and a reason some economists questioned the indicator's continuing reliability in the post-COVID economy.
What should I watch for next?▾
The most important signals to track while this scenario is active: Six-month LEI change below negative 3% annualized; Credit spreads widening above 500 bps confirming the LEI signal. The full list is on this page under "What to Watch For." These signals are the ones that historically preceded the scenario either resolving or accelerating.
How should I interpret the current state of this scenario?▾
Track USSLIND and its six-month annualized change monthly. Compare against the Conference Board LEI and the Convex Recession Index for convergence or divergence. LEI weakness alongside tightening credit spreads is the most concerning combination, while LEI weakness with credit spreads still tight often produces the false-signal scenarios (2022-2023).
Is this a prediction or a conditional analysis?▾
This is conditional analysis, not a prediction that the scenario will happen. Convex describes what typically follows once the trigger fires and shows how close or far the current data is from that trigger. The page is informational; it does not constitute financial advice.
