Bond yields are rising on fiscal math, not just inflation — and credit is starting to widen

What moved

Bond markets sold off this week. Fixed income markets, with the exception of floating-rate debt, sold off during the week, according to DoubleLine's analysts, after October consumer price data and hawkish remarks from Federal Reserve Governor Christopher Waller. The German 2-year yield rose roughly 17 basis points on the week, UBS notes, and Japanese 10-year yields climbed to their highest levels since 22 October. m:…9088 m:…7663

Producer prices tell the same story from the other side. Final demand producer prices rose 0.3% in October 2026, according to PNC Economics, with year-over-year inflation reaching 6.5%. Goods producer prices rose 0.5% in the month and sit 10.2% higher than a year ago, while services producer prices rose 0.2% and are 5.0% higher year over year. Energy producer prices fell 0.1% in the month but are up 36.8% year over year. m:…4556

The October consumer price data raised the odds of a 50-basis-point hike at the Federal Reserve's December 9 meeting, DoubleLine notes, with the probability at approximately 10% by Friday. Russell Investments anticipates one additional rate hike in December, and PNC Economics projects two more 25-basis-point rate hikes through early 2027. Investors are also weighing comments from Christopher Waller regarding a potential 50-basis-point hike in December, according to UBS. m:…9088 m:…6478 m:…4556 m:…7663

The fiscal thread

But inflation is only half the story. The federal budget gap was $404 billion in October, DoubleLine reports, 42% higher than in the same period last year. US debt currently stands at approximately 101% of GDP, according to Russell Investments, and could reach 120% of GDP within a decade according to Congressional Budget Office projections. m:…9088 m:…6478

Russell Investments puts a price on that trajectory: each percentage-point increase in the debt-to-GDP ratio may reduce real economic growth by approximately 3.3 basis points and increase borrowing rates by 3 to 5 basis points. The implication is that the fiscal position itself is becoming a market variable, not just a backdrop. m:…6478

Credit is already responding. Credit spreads widened by 21 basis points in technology and 34 basis points in communications in October, Russell Investments notes, and spreads on Caa-rated bonds widened by 109 basis points during the month. The weakest credits are widening fastest, which is what usually happens when borrowing costs rise and growth is in question. m:…6478

What it means for portfolios

For portfolios, the message is mixed rather than bleak. Elevated starting yields have improved the appeal of the traditional 60/40 balanced portfolio, UBS argues, and the firm rates high-grade and investment-grade bonds as Attractive. High-quality bonds offer income, capital appreciation potential and a cushion against equity market declines, according to UBS, but the firm also warns that the diversification benefit of bonds depends on the cause of equity market declines, and that completion assets can provide differentiated returns. m:…7663

Russell's reading points the same way: persistent inflation and resilient employment reinforce expectations for higher interest rates. Nonfarm payrolls increased by 165,000 in October, and the October estimate for core personal consumption expenditures inflation is 3.3% year over year, a combination that leaves little room for the bond market to relax. The spread between 2-year and 10-year Treasury yields has narrowed to around 30 basis points, Russell notes, which leaves little cushion if growth disappoints. m:…6478
