Rising Treasury Yields Track Fed Policy, Not AI Spending

Treasury yields are rising on shifting Fed policy expectations and inflation concerns, not AI spending, according to PIMCO’s latest analysis.

Treasury yields have increased in recent months, driven primarily by changing expectations for Federal Reserve policy.
Despite soaring capital commitments to AI infrastructure, PIMCO maintains that immediate bond market moves reflect cyclical forces, not AI-driven term premiums.
Long-term pressures from AI-related debt could impact yields in the future, but for now, policy uncertainty remains the dominant factor.

Key Takeaways

Yields Respond to Policy Shifts Not AI Boom

Yields on US Treasurys have climbed sharply since late February, sparking debate over what’s driving the moves. Despite record-setting investment flowing into artificial intelligence infrastructure, PIMCO Managing Director Lotfi Karoui argues that the day-to-day action in the bond market is still anchored in shifting monetary policy and geopolitical events. According to PIMCO, blaming AI’s buildout for higher yields misses the mark—instead, it’s the Fed’s next move (and market speculation about it) that’s front and center.

Policy Expectations and Inflation Take Center Stage

PIMCO traces the recent run-up in longer-dated Treasury yields to changes in investor expectations around inflation and central bank action. With energy prices rising since the outbreak of war in Iran, inflation pressures have filtered into sectors across the US economy, impacting construction, transport, and more. As concern about persistent inflation grows, markets have started to price in the risk that the Fed could resume rate hikes. According to Karoui, analysis of the 10-year Treasury shows that most of the increase has come from repricing rate expectations, not from additional risk tied to the AI boom.

AI Lease Obligations Remain a Slow Build

AI-driven capital flows are enormous, but their effect is more gradual. Moody’s Ratings estimated in February 2026 that major hyperscalers such as Amazon, Meta, Microsoft, and Alphabet have $662B in lease obligations for yet-to-begin projects—liabilities that are still largely off-balance-sheet. Gartner projects $2.5T in global AI spending this year. Still, PIMCO views these as slower-developing pressures. Hyperscalers are locking in long-term borrowing, and already account for more than 30% of this year’s 30-year Treasury issuance, but these moves haven’t yet significantly shifted the term premium or overall yield structure.

Why It Matters

The headline move in yields carries immediate implications for CRE capital markets. Higher Treasury rates drive up real estate financing costs, which can compress yields and chill transaction activity. According to PIMCO, the forces moving the bond market today—Fed policy uncertainty and energy-driven inflation—make it harder to predict when rate relief might arrive. While debt-fueled AI growth could pressure yields over time, CRE borrowers and investors should stay focused on monetary policy and geopolitical risk in the near term.

What’s Next

CRE pros should watch for further developments in monetary policy as the Fed signals its intentions in response to persistent inflation threats. Any signs of accelerated AI refinancing or visible impacts on the Treasury market may take years to fully emerge, but for now, the bond market’s fate is closely tied to inflation, energy, and rate speculation. Follow future Fed guidance and keep an eye on hyperscaler borrowing trends as potential incremental yield drivers down the line.
