The Regime Matrix: Why Inflation + Fed Policy Matters More Than Either Alone
Most regime analysis looks at one variable. We combined inflation and Fed policy into 8 distinct regimes. The results reveal a danger zone you might be entering right now.
Current Regime Alert: Just Entered Cutting Territory
The Fed just crossed into cutting territory in December 2025. Historically, "Moderate Inflation + Cutting" has been one of the worst environments for equities.
S&P 500 average monthly returns across 8 combined regimes. Cutting cycles are dangerous regardless of inflation.
I The Complete Regime Matrix
We classified each month from 2005-2025 into one of 8 regimes based on inflation level and Fed policy direction. The results show a clear pattern: cutting cycles are dangerous regardless of inflation, but the combination of high inflation with cutting is catastrophic.
| Regime | Months | SPY Avg Return | Win Rate | Volatility | Rating |
|---|---|---|---|---|---|
| Low Inflation + Pause | 85 | +1.61% | 71% | 3.56% | BEST |
| Moderate Inflation + Pause | 75 | +1.27% | 72% | 3.60% | GOOD |
| Moderate Inflation + Hiking | 23 | +1.00% | 70% | 2.59% | OK |
| Low Inflation + Cutting | 14 | +0.81% | 64% | 8.02% | VOLATILE |
| High Inflation + Pause | 13 | +0.50% | 62% | 4.71% | NEUTRAL |
| High Inflation + Hiking | 18 | +0.38% | 67% | 5.19% | NEUTRAL |
| Moderate Inflation + Cutting | 13 | -1.15% | 38% | 6.09% | DANGER |
| High Inflation + Cutting | 9 | -3.25% | 22% | 4.01% | WORST |
II What Works in Each Regime
Worst Regime: High Inflation + Cutting
9 months, -3.25%/mo avg, 22% win rate (think 2008)
III Factor Performance by Inflation
Inflation level has the largest impact on factor returns. Low inflation (<2%) is the sweet spot for equities. High inflation (>4%) crushes everything except gold.
| Factor ETF | High Inflation (>4%) | Moderate (2-4%) | Low Inflation (<2%) | Spread (H-L) |
|---|---|---|---|---|
| QQQ Growth | -0.63% | +1.33% | +2.07% | -2.70pp |
| IWF Growth | -0.44% | +1.13% | +1.72% | -2.16pp |
| IWM Small Cap | -0.90% | +0.69% | +1.67% | -2.57pp |
| SPY Market | -0.40% | +0.93% | +1.50% | -1.90pp |
| IWD Value | -0.50% | +0.71% | +1.32% | -1.82pp |
| XLF Financials | -1.03% | +0.68% | +1.44% | -2.47pp |
| TLT Bonds | -0.35% | +0.43% | +0.47% | -0.82pp |
| GLD Gold | +1.26% | +1.12% | +0.77% | +0.49pp |
| XLE Energy | +1.53% | +0.02% | +1.07% | +0.46pp |
IV Industrial Production: The Contrarian Signal
Here's a surprise: factors perform better during IP contraction than expansion. Why? Markets trade the second derivative. Contraction often follows peak tightness and leads to rate cuts and recovery rallies.
Contracting (<-2% YoY)
Flat (-2% to +2%)
Expanding (>+2% YoY)

VI Current Positioning
Summary
- Inflation + Fed Policy combined is more predictive than either alone. The best regime (Low Inflation + Pause) produces +1.61%/mo. The worst (High Inflation + Cutting) produces -3.25%/mo.
- Cutting cycles are dangerous regardless of inflation. When the Fed cuts, it's usually because something is broken. TLT is the only consistent winner during cuts.
- We just entered cutting territory in December 2025. With moderate inflation + cutting, historical returns are -1.15%/mo with a 38% win rate.
- Gold is the only asset that performs better in high inflation. +1.26%/mo in high inflation vs +0.77%/mo in low inflation.
- IP growth is contrarian. Factors perform better during contraction than expansion because markets price in recovery before data confirms it.
