Why I Watch the 30-Year U.S. Treasury Yield Before the S&P 500

Many investors spend their days analyzing stocks but overlook a chart that influences virtually every market: the 30-Year U.S. Treasury yield (TVC:US30Y on TradingView).

In my view, it is one of the best barometers of the long-term cost of capital.

When yields rise, companies face higher financing costs, valuations become more demanding, and growth-sensitive sectors such as technology, real estate, and utilities are generally the first to come under pressure. Conversely, a lasting decline in yields often supports risk assets.

THE INDICATORS I USE ON TRADINGVIEW

📈 SMA 200

This is my primary indicator.

• Yield above the 200-day SMA: yields are in an uptrend.
• A rising 200-day SMA: structural pressure remains on bond prices.
• The further the yield moves above its 200-day SMA, the greater the risk of a pullback or consolidation.

☁️ Ichimoku

I mainly monitor:

• the yield’s position relative to the cloud;
• the slope of the Kijun-sen;
• the slope of the leading cloud, especially Senkou Span A;
• the Chikou Span.

A yield that remains above the cloud with a rising Kijun-sen generally reflects a solid trend.

📊 ADX (14)

ADX measures the strength of the move.

• below 20: no clear trend;
• above 25: a trend is developing;
• above 30: a strong trend.

📉 MACD

I mainly look for:

• moves above the zero line;
• signal-line crossovers;
• divergences.

MACD often helps filter false signals when yields move in a directionless market.

📦 Volume Profile

Even though the yield itself has no true traded volume, Volume Profile can still highlight the price zones where the market has spent the most time.

I pay particular attention to:

• the Point of Control (POC);
• High Volume Nodes (HVNs);
• Low Volume Nodes (LVNs).

📐 Linear Regression

This is very useful for judging whether yields are trading near the center of their trend or in an overextended area.

📏 ATR

ATR simply measures volatility.

A simultaneous rise in ATR and ADX often confirms an acceleration in the trend.

WHAT ELSE I MONITOR

I regularly compare the 30-year yield with:

• the 10-Year U.S. Treasury yield;
• the S&P 500;
• the Nasdaq;
• the U.S. Dollar Index (DXY);
• gold.

This cross-market view often makes sector rotations easier to understand.

MY DASHBOARD

⭐ 200-day SMA
⭐ Ichimoku
⭐ ADX
⭐ MACD
⭐ Volume Profile
⭐ Linear Regression
⭐ ATR

In my view, following equity indices without monitoring long-term interest rates is like driving without looking several hundred meters down the road.

The bond market often sends the first signals.
