# Most Reliable Recession Indicators: Yield Curve, Sahm Rule & LEI

## Definition

Recession indicators are a set of quantitative economic signals designed to identify the onset of recessions in real time, filling the gap left by NBER's official recession declarations which typically come 6-12 months after a recession begins. The three most established US recession indicators are the yield curve inversion (10-year minus 3-month Treasury spread), the Sahm Rule (unemployment rate trigger), and the Conference Board Leading Economic Index (composite of 10 leading indicators). Each uses a different data domain — bond markets, labor markets, and a broad composite — providing independent signal confirmation when combined. [src1, src3]

## Key Properties

- **Yield curve inversion**: The 10Y-3M Treasury spread turning negative has preceded every US recession since 1955; inversions exceeding 3 months show 87.5% accuracy (7 of 8 recessions since 1968), with lead times of 6-24 months; the NY Fed publishes a formal recession probability model based on this spread [src3]
- **Sahm Rule**: Triggers when the 3-month moving average of the national unemployment rate rises 0.50pp or more above its 12-month low; correctly identified all 11 recessions since 1950 with only two false positives (1959, where a recession followed 6 months later); typically triggers about 3 months into a recession, well before NBER's declaration [src1, src4]
- **Conference Board LEI**: A year-over-year decline of more than 4% has preceded every US recession since 1960; the 10-component composite forecasts economic activity 6-9 months ahead; LEI declined 0.2% in December 2025 (fifth consecutive decline) [src2]
- **Supplementary signals**: BBB-Treasury credit spread above 200bps, ISM Manufacturing PMI below 45 for two consecutive months, declining real retail sales, rising continuing jobless claims [src2]
- **Current readings (late 2025)**: Sahm Rule at 0.35pp (below 0.50 trigger), yield curve normalized after 2022-2023 inversion, LEI in gradual decline [src1]

## Constraints

- All three indicators are calibrated for the US economy — they have weaker predictive power for countries with structurally different labor markets or financial systems [src4]
- No single indicator is sufficient — the most robust recession assessment combines all three with supplementary signals (credit spreads, employment breadth, retail sales) [src2]
- The 2022-2024 period produced extended false signals: the yield curve inverted for 16 months without recession; the LEI declined 15 of 18 months without recession; the Sahm Rule was briefly approached at 0.53pp (August 2024) without recession [src1, src2]
- NBER declares recessions 6-12 months after onset — these real-time indicators are faster but more error-prone than the official determination [src3]
- The Sahm Rule was designed for automatic fiscal stabilizer activation, not standalone recession forecasting — Claudia Sahm herself noted that immigration-driven labor force growth can push up unemployment without signaling true recession [src4]

```

## Application Checklist

### Step 1: Check Real-Time Indicator Levels
- **Inputs needed**: Current Sahm Rule reading (FRED: SAHMREALTIME), 3m10y and 2s10s Treasury spreads, LEI year-over-year change
- **Output**: Dashboard of current indicator levels vs. their recession thresholds
- **Constraint**: Use the 3-month moving average for all indicators — single-month readings are too noisy for recession calls [src1]

### Step 2: Assess Indicator Agreement
- **Inputs needed**: Results from Step 1 — which indicators are at or beyond their thresholds
- **Output**: Agreement score (0-3 core indicators triggering, plus supplementary signals)
- **Constraint**: If only one indicator is triggering, the false positive rate is historically high (especially post-2020). Require at least two confirming indicators before elevating risk assessment [src2]

### Step 3: Check for Structural Distortions
- **Inputs needed**: Current monetary policy regime (QE/QT status), labor force composition changes (immigration trends), fiscal policy posture
- **Output**: Assessment of whether current indicator readings may be structurally distorted
- **Constraint**: In QE/QT transition periods, yield curve signals are unreliable — weight the Sahm Rule and real economy indicators (retail sales, industrial production) more heavily [src3]

### Step 4: Determine Action Level
- **Inputs needed**: Agreement score from Step 2, distortion assessment from Step 3
- **Output**: Risk classification (low/moderate/elevated/high) with specific recommended actions
- **Constraint**: A "high" rating requires at least 2 core indicators triggering with no structural distortion explanation — otherwise classify as "elevated" with monitoring [src2]

## Anti-Patterns

### Wrong: Treating yield curve inversion as an immediate recession signal
An inverted curve signals elevated recession risk within 7-24 months, not an imminent downturn. Investors who sold immediately at the July 2022 inversion would have missed a 40%+ S&P 500 rally. [src3]

### Correct: Use inversion as a risk management trigger with a time horizon
Begin stress-testing business plans, gradually reduce portfolio risk, and establish monitoring cadence for confirming indicators. The actionable signal may be the curve's un-inversion, not the inversion itself. [src3]

### Wrong: Dismissing indicators after a single false signal
The 2022-2023 yield curve inversion not producing an immediate recession led many to declare the indicator "broken." The long-lag hypothesis (24+ months) and the QE-distortion hypothesis are both untested at this scale. [src2]

### Correct: Evaluate indicator reliability across the full historical record, not just the most recent cycle
The yield curve's 87.5% accuracy across 8 cycles is more informative than one potential miss. Adjust confidence intervals, don't discard the signal. [src3]

### Wrong: Using the Sahm Rule as a standalone recession forecast
The Sahm Rule was designed as a trigger for automatic fiscal stabilizers (stimulus checks), not as a forecasting tool. It typically fires 3 months into a recession, making it a confirmation signal, not a leading one. [src4]

### Correct: Combine the Sahm Rule with leading indicators for early warning
Pair the Sahm Rule (real-time confirmation) with yield curve and LEI (forward-looking) to get both early warning and real-time validation. The Sahm Rule's value is speed — it confirms what leading indicators predicted. [src1]

## Common Misconceptions

- **Misconception**: Yield curve inversion always means recession within 6 months.
  **Reality**: Lead times range from 7 to 24 months. The 2005-2007 inversion preceded the Great Recession by nearly 2 years. The 2022-2023 inversion (16 months) has not produced a recession as of late 2025. [src3]

- **Misconception**: The Sahm Rule triggered a false positive in August 2024.
  **Reality**: The Sahm Rule reading of 0.53pp in August 2024 was elevated by immigration-driven labor force growth increasing the unemployment rate without underlying economic weakness. Claudia Sahm herself noted this structural distortion. [src4]

- **Misconception**: If the LEI is declining, a recession is inevitable.
  **Reality**: The LEI declined 15 of 18 months through early 2024 without a subsequent recession. Financial components (stock prices, yield curve) can dominate the index during monetary policy transitions, producing false signals. [src2]

- **Misconception**: NBER's recession declaration is timely enough for decision-making.
  **Reality**: NBER typically declares recessions 6-12 months after they begin. The 2020 recession was declared in June 2020, four months after it started. Real-time indicators are essential precisely because the official arbiter is backward-looking. [src1]

## Comparison with Similar Concepts

| Concept | Key Difference | When to Use |
|---|---|---|
| Recession Indicators | Multi-indicator recession probability assessment | Specifically evaluating whether a recession is approaching or underway |
| Yield Curve Analysis | Deep analysis of a single indicator (term structure) | When the yield curve itself is the focus, including shapes, measures, and models |
| Economic Indicators | Broad classification (leading/coincident/lagging) | When monitoring overall economic health, not recession-specific risk |
| Interest Rate Impact | How rate levels affect businesses and valuations | When analyzing rate sensitivity for specific investments or business decisions |
