# Global bond sell-off intensifies as US economic overheating fears grow Strong PMI data and oil price rebound fuel expectations of aggressive Fed rate hikes - **Source:** [Business | The Guardian](https://www.theguardian.com/uk/business) - **Published:** 2026-09-24 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/945a2e22-077c-43c5-971c-e32ea1931368 ## Rate hike expectations surge Markets now price a 55% chance of half-point Fed rate increases by December, following this month's hike. CME FedWatch indicates potential for two quarter-point hikes as traders react to strong economic indicators. The shift reflects growing consensus that the Fed needs to act more aggressively than previously anticipated to curb inflation pressures. ## Historic Treasury yield spike The 10-year Treasury yield jumped 15.2 basis points yesterday - the largest single-day increase since April 2025's market turmoil. This dramatic move signals deep bond market repricing amid changing rate expectations. The sell-off reflects investor concerns about prolonged higher rates rather than temporary policy tightening. ## PMI data shows overheating September flash PMIs revealed the fastest US economic expansion in over five years, with new orders growing at April 2022 levels. Manufacturing hiring reached February 2021 peaks, while resilient consumer spending and AI investment offset energy price concerns. These indicators suggest the economy may be running beyond sustainable capacity. ## Dual inflationary pressures Elevated input costs persist due to high energy prices and ongoing supply chain constraints, according to PMI data. Simultaneously, strong demand pushes output prices higher. This combination creates a challenging environment for Fed policymakers trying to balance growth and inflation control. ## Labor market tightness With unemployment at 4.1% and growth above trend, the Fed faces classic overheating signals. The strong job market fuels wage growth and consumer spending, creating self-reinforcing inflationary pressures. Policymakers must now consider whether demand needs active cooling via rate hikes. ## October hike probability Futures markets now assign a 71% likelihood to a Fed rate increase at the October meeting. This represents a significant shift from just weeks ago, when many expected the hiking cycle to pause. The repricing reflects incoming data showing persistent economic strength and price pressures. ## Global spillover effects The US bond sell-off creates ripple effects across global fixed income markets, pushing yields higher worldwide. Other central banks face pressure to align with Fed policy to prevent currency depreciation and capital outflows, potentially accelerating global monetary tightening. ## Policy dilemma intensifies The Fed must now weigh the risk of overtightening against allowing inflation to become entrenched. With strong growth metrics but stretched supply chains, policymakers face complex trade-offs. Their coming decisions will shape market trajectories through year-end and beyond. ## Sources covering this story - https://www.theguardian.com/business/live/2026/sep/24/global-bond-sell-off-us-economy-fears-stock-markets-ftse-dollar-pound-latest-news-updates — --- _Summary written by Brifing from the original reporting.
