Yield surge and inflation expectations
The benchmark 10-year Treasury yield climbed to 5.23% on Friday, marking its highest level since 2007. Earlier this month, the yield was trading just below 4.8%, making the rapid move above 5% a sharp shift in investor sentiment. Bond yields and prices move in opposite directions, so the jump reflects a selloff in Treasury prices.[S1]
Persistent price pressures are among the drivers of the recent jump. According to the University of Michigan's consumer sentiment survey, expected inflation over the coming year climbed to 4.6% in September, up from 4% in August and the loftiest level since June. Meanwhile, CME FedWatch data on fed funds futures points to a 64% probability of an October rate increase, reflecting bets that the Federal Reserve will tighten further.[S1]
Bond supply from deficits and AI borrowing
Thierry Wizman, global FX and rates strategist at Macquarie Group, argued that bond issuance is a bigger driver this year than the inflation narrative. He noted that yields at these levels are not unusual on their own, especially without extreme inflation expectations or an aggressively tightening Fed. What stands out, he said, is the presence of a very strong investment cycle.[S1]
Washington is selling debt to cover a sizable budget shortfall, and corporations are taking on large amounts of borrowing to build out artificial intelligence capacity. Vanguard calculates that Alphabet, Amazon, Meta Platforms, Microsoft and Oracle together issued roughly $132 billion of debt through July, a steep rise from the approximately $35 billion yearly average seen from 2020 through 2024. AI-linked issuance overall might total $300 billion to $570 billion this year as data-center, chip and utility players borrow for the expansion.[S1]
Wizman noted that hyperscalers and their suppliers will probably sustain heavy bond issuance for the rest of this year and into the next, which points to the possibility of yields climbing further. Rising yields tend to pressure equities by increasing what companies pay to borrow and by drawing income-focused investors toward bonds instead.[S1]
