- The 10-year Treasury yield leapt to 5.23% on Friday, its highest level since 2007, after trading just below 4.8% earlier this month.
- Fed funds futures show a 64% likelihood of a rate hike in October per the CME FedWatch tool, as investors price in further tightening amid stubborn inflation.
- The University of Michigan reported year-ahead inflation expectations surged to 4.6% in September, up from 4% in August — the highest reading since June.
- Thierry Wizman, global FX and rates strategist at Macquarie Group, argued the yield surge is driven more by heavy bond issuance than inflation, calling the current investment cycle 'abnormal' despite a non-aggressively tightening Fed.
- Vanguard estimates Alphabet, Amazon, Meta, Microsoft, and Oracle issued roughly $132 billion of debt through July, up sharply from the ~$35 billion annual average between 2020 and 2024.
- Broader AI-related debt issuance could reach $300 billion to $570 billion this year as data-center, semiconductor, and utility companies borrow to finance the buildout.
- Wizman warned yields could go higher, noting hyperscaler capital-spending plans are likely to keep bond issuance elevated through this year and into next.
Why it matters: Heavy AI-related bond issuance — up to $570 billion this year per Vanguard's framing — is flooding the market at the same time the federal government is financing a large deficit, creating dual supply pressure on Treasuries that even a patient Fed can't offset. Mortgage rates and corporate borrowing costs tied to the 10-year yield are already pricing in this reality, squeezing both homebuyers and the same companies powering the AI boom.
