The yield on the US 10-year Treasury note surged to 5.11% on Wednesday, according to market data reported by CNN, touching its highest level in nearly two decades as strong corporate activity figures drove up inflation concerns. Driven by mounting energy costs and accelerated business pace, the benchmark yield jumped 15 basis points to establish a fresh high for the year, last seen at comparable levels in 2007.
Rising Business Activity and Energy Costs Fuel Bond Sell-Off
Economic indicators released by S&P Global showed that US business activity accelerated in September at its fastest pace since July 2021. According to the reporting, input costs escalated simultaneously due to rising energy prices, shifting trader sentiment regarding monetary policy. Following the data release, the probability of a Federal Reserve interest rate increase in October climbed to 66%, up from 55% the previous day, based on CME FedWatch data cited by CNN.
Treasury yields climbed across the entire maturity curve during the session. The 30-year bond yield rose 11 basis points to 5.4%, reaching an intraday peak not seen since 2007 and a closing high matching levels from 2004. Meanwhile, the two-year Treasury yield, which closely tracks central bank policy expectations, increased by roughly 16 basis points to 4.9%, marking its highest point since 2024. Vail Hartman, a US rates strategist at BMO Capital Markets, noted in a report covered by CNN that the robust economic readings leave ample room for policy rates and Treasury yields to extend gains in the near term.
Geopolitical Pressures and Oil Price Volatility
Energy markets contributed directly to the fixed-income volatility on Wednesday. Front-month Brent crude oil futures advanced 3.86% to close at US$ 103.08 per barril, breaking a five-session losing streak as traders evaluated potential disruptions to Middle East shipping lanes. Chip Hughey, managing director of fixed income at Truist Advisory Services, described the convergence of rising oil prices and strong economic data as a “perfect storm” that pushed yields higher across all durations.
Geopolitical friction intensified during the session as Iranian President Masoud Pezeshkian addressed the United Nations General Assembly in New York. Pezeshkian stated that Iran would not submit to the United States amid ongoing tensions surrounding the Strait of Hormuz, asserting that Tehran would not permit the US to leverage the crucial maritime route to impose security threats or restrict access to regional waterways.
The surge in borrowing costs immediately impacted domestic equities. The S&P 500 fell 0.75% by the closing bell, while the Nasdaq Composite dropped 1.1%, reflecting broader investor anxiety over tighter financial conditions and a shift away from earlier Wall Street expectations of monetary easing.
Treasury Repurchase Program and Market Impact
In an effort to counter rising yields, the US Department of the Treasury continued its expanded debt repurchase operations. Treasury announced plans to conduct a buyback of up to US$ 6.000 millones on Thursday, following an earlier operation on September 10 that absorbed US$ 5.200 millones in long-term securities. The current program scales up regular operations—which typically total US$ 2.000 millones—to at least double or triple that volume between September and November.
Tony Miano, a global investment strategy analyst at the Wells Fargo Investment Institute, told CNN that the market indicates a genuine monetary tightening cycle is underway, with the 10-year yield shifting significantly higher from its 4.15% level at the start of the year.
