Quick Thoughts: Bond Market Blues—Real or Inflationary?

The recent rise in Treasury yields is mainly a real-rate shock rather than a repeat of the inflation-driven 2022 selloff, but it still threatens growth and equity returns.

• The 10-year Treasury yield has risen about 45 basis points over the past month to roughly 5.25%, with only 1 basis point coming from higher long-term inflation expectations and about 44 basis points from higher real yields.
• Since the end-February low, nominal 10-year yields have climbed about 125 basis points, while inflation expectations increased only 9 basis points, implying roughly 116 basis points of higher real yields.
• The increase in real rates may reflect stronger-than-expected growth, reduced expectations for near-term Federal Reserve easing, heavy Treasury issuance, larger fiscal deficits, investment linked to artificial intelligence, infrastructure and energy, and a higher term premium.
• This differs from the first four months of 2022, when 10-year yields rose roughly 120 basis points and about one-third of the increase reflected rising inflation expectations; inflation is now lower, although price pressures remain sticky in some areas.
• Strong 2026 earnings have outpaced the S&P 500's rise, pushing its forward price-to-earnings ratio from roughly 22x at the start of the year to about 18x, but higher real rates are tightening financial conditions for housing and lower-quality borrowers.

Takeaway: Equities may absorb higher yields for now, but the drag could intensify in 2027 as fiscal support fades and capital-expenditure growth peaks; investors should monitor both nominal and real yields because either renewed inflation or further real-rate increases could hurt profits and valuations.
