Higher Interest Rates: What Fixed Income Investors Should Know

Higher rates driven mainly by resilient growth have improved fixed-income entry yields without causing broad credit deterioration, making active duration and credit selection attractive.

• Between February 27 and September 30, 2026, the 10-year Treasury yield rose about 135 basis points to 5.28%, while the two-year yield increased about 151 basis points and the curve flattened as markets moved from expecting Fed cuts to anticipating further tightening.
• The move differed from 2022 because stronger real yields, rather than surging inflation expectations and aggressive Fed tightening, explained most of the increase; resilient employment, consumer spending, corporate earnings, and private investment supported growth.
• From the start of 2026 to September 30, investment-grade corporate spreads widened only from 78 to 80 basis points, while high-yield spreads moved from 281 to 312 basis points, suggesting that stronger growth helped borrowers absorb higher financing costs.
• Starting yields are historically supportive: the Bloomberg U.S. Aggregate yield exceeded 5% in only 37 of 288 months over the past 24 years, and those months were followed by an average 12-month return of 6.5%; when the 10-year Treasury started between 5% and 5.99%, average subsequent annualized returns were 6.7% over three years and 6.6% over five years.
• Credit performance was highly dispersed through September 30: Single-B corporate bonds returned 1.05% year to date versus -6.01% for AAA corporates, while AI infrastructure financing is creating opportunities across investment-grade bonds, high-yield debt, and project-related structures but adds construction, collateral, completion, and refinancing risks.

Takeaway: Higher starting yields provide income and some protection against further rate rises, but investors should favor active duration management and issuer selection because leveraged borrowers remain vulnerable and credit outcomes vary sharply by rating, sector, and structure.
