The new bond playbook: Fed credibility, fiscal risk, AI investment, and opportunity

Higher yields and divergent macroeconomic forces create a more attractive but selective environment for active bond investors.

• Payroll growth has slowed toward an estimated monthly breakeven pace of roughly 50,000 jobs, while unemployment remains in the low 4% range and inflation is making limited progress toward the Fed’s 2% target.
• The Fed raised its policy rate to 3.75%–4%, which Vanguard views as a modest recalibration that reverses the 2025 insurance cuts rather than the beginning of an extended hiking cycle.
• Persistent fiscal deficits and high issuance could increase the term premium and steepen yield curves; Vanguard is cautious on French and Italian sovereign bonds and U.K. gilts, while viewing German bunds as relatively attractive versus Treasuries.
• AI infrastructure investment is expanding bond issuance across corporate, asset-backed, securitized, and municipal markets; eight hyperscalers represent 31% of the S&P 500 but only about 2% of the Bloomberg U.S. Aggregate Bond Index.
• The Bloomberg U.S. Aggregate has yielded more than 5% since August 31, 2026, and rates would need to rise nearly a full percentage point to produce a flat one-year return at current yields, although wider spreads or higher rates can still generate losses.

Takeaway: Investors should favor short- and intermediate-duration bonds, use deep research and relative-value analysis to select AI-related and other credit exposures, and limit long-duration risk because fiscal pressure, inflation, term premiums, and tight credit spreads leave less room for error.
