Why Seven Models Instead of One
As we have seen with both the yield curve (16-month inversion in 2022-2023 with no recession) and the Sahm Rule (triggered in July 2024 due to labor supply shifts rather than demand weakness), individual recession indicators have blind spots. Each model was designed to capture a specific mechanism through which recessions develop, and no single mechanism explains all recessions.
Combining multiple models addresses this limitation. When only one model flashes warning, it might be a false positive driven by unusual circumstances. When five or six models converge, the signal is much harder to dismiss.
What the Seven Models Capture
The yield curve model captures financial market expectations about future growth and monetary policy. Its strength is its long track record. Its weakness is highly variable timing and the recent false signal.
The Sahm Rule captures labor market deterioration through rising unemployment. Its strength is simplicity and historical accuracy. Its weakness, revealed in 2024, is sensitivity to labor supply shocks that mimic demand weakness.
Leading economic indicators capture a broad basket of forward-looking metrics. Their strength is breadth. Their weakness is heavy manufacturing weighting in a services-dominated economy.
Credit spread models capture financial stress through the gap between corporate and Treasury yields. Their strength is real-time market pricing. Their weakness is sensitivity to central bank interventions that can suppress spreads artificially.
Consumer sentiment models capture household confidence and spending intentions. Their strength is capturing the demand side of the economy. Their weakness is that sentiment can be temporarily influenced by political factors unrelated to economic fundamentals.
Housing market indicators capture one of the most interest-rate-sensitive sectors of the economy. Housing starts, permits, and prices tend to lead the broader economy. Their weakness is regional variation, since a national housing slowdown can mask pockets of resilience.
Manufacturing and industrial production indices capture the goods-producing sector. While manufacturing is a smaller share of GDP than services, it tends to be more cyclical and often leads broader economic turns.
The Power of Convergence
The composite scorecard assigns a status to each model: green (no recession signal), yellow (approaching trigger threshold), or red (triggered). The number of models in each state, plus the trajectory (are models moving from green to yellow, or from yellow back to green), gives you a subtle read on recession probability.
Historical analysis suggests that when four or more models simultaneously trigger, a recession has always followed within 12 months. When only one or two trigger, the false positive rate is high. The threshold of three models triggering is the ambiguous zone where further investigation is warranted but the signal is not definitive.
Integrating 50+ FRED Indicators
The Federal Reserve Economic Data (FRED) database provides over 800,000 economic data series. The scorecard draws from 50+ of these indicators, organized under the seven model categories. Initial jobless claims, building permits, ISM manufacturing PMI, consumer confidence, retail sales, industrial production, and dozens more feed into the composite view.
The advantage of pulling from FRED is data quality and timeliness. Most series are updated weekly or monthly, giving you a near-real-time view of economic conditions. The disadvantage is that economic data is revised, sometimes substantially, so the scorecard needs to account for the difference between the initial release and the final revised number.
Practical Application
The scorecard is not designed to time the market. Recession calls are notoriously difficult even for professional economists, and the lag between economic deterioration and market impact is unpredictable. What the scorecard does is inform your risk posture. When the majority of models are green, you can lean into risk assets with confidence. When multiple models are yellow or red, reducing position sizes, tightening stops, and increasing cash allocation is prudent, even if you do not know exactly when the downturn will hit.
