Long-End Yields Reprice Equity Risk, Unevenly

The US 30-year Treasury yield has climbed from ~5.0% in early July to 5.34% , its highest since 2007.

This isn't primarily a Fed story. Pressure sits at the long end: wide fiscal deficits and heavy Treasury supply, rising term premium, inflation and oil risk, and AI-related capex increasingly financed in the bond market. US federal interest costs now exceed the defence budget.

That looks like a regime shift, not noise.

Using Quant Insight's MFERM macro factor model, we screened S&P 500 sensitivity to a steeper 5s30s curve since 1 July. 59% of market cap is hurt by long-end-led steepening.

Hit hardest:
Semiconductors, Autos, Insurance, Tech Hardware, Banks

Relative winners:
Telecom, Energy, Software. Semis and Software sit in the same Tech bucket, yet moved in opposite directions.

The IGV/SOXX ratio has tracked the 30yr yield closely. Sector labels hide macro risk.
