Yield Curve Inversion Monitor

Overview

This pillar monitors the US Treasury yield curve, a historically reliable predictor of economic recessions. By tracking key spreads, it provides advance warning of potential downturns, influencing markets from interest rates to equity performance.

What It Does

It continuously tracks the difference between short-term and long-term US Treasury bond yields, specifically the 2-year vs 10-year (2s10s) and 3-month vs 10-year (3m10y) spreads. The pillar identifies when these spreads invert, meaning short-term rates are higher than long-term rates. It also analyzes the duration of the inversion and the speed of its return to normal.

Why It Matters

A yield curve inversion has preceded every major US recession for the past 50 years. This pillar provides a powerful, forward-looking signal on the health of the economy, giving traders a significant edge in markets related to GDP growth, monetary policy, and asset class performance.

How It Works

The system fetches daily yield data for 3-month, 2-year, and 10-year US Treasuries. It then calculates the spreads by subtracting the shorter-term yield from the longer-term yield. The pillar flags an inversion when the spread drops below zero and tracks the number of consecutive days it remains inverted, providing a signal whose strength increases over time.

Methodology

The core calculation is the daily spread in basis points (bps): Spread = (10-Year Treasury Yield) - (Shorter-Duration Yield). An inversion is officially flagged when the spread is less than or equal to 0 bps for three consecutive trading days. The model also calculates a 20-day moving average of the spread to identify the underlying trend and momentum.

Edge & Advantage

While the concept is well-known, this pillar quantifies the signal's duration and steepening velocity, providing a more nuanced outlook on recession timing than simple inversion alerts.

Key Indicators

• 2s10s Spread

  high

  The difference between 10-year and 2-year Treasury yields. A key long-term recession indicator.

• 3m10y Spread

  high

  The difference between 10-year and 3-month Treasury yields. Often considered a more immediate signal by the Federal Reserve.

• Inversion Duration

  medium

  The number of consecutive days the spread remains negative. Longer inversions are historically stronger signals.

Data Sources
