Strong U.S. economic data, including the September flash PMI surging to a 62-month high of 58.4 with robust employment and input-cost pressures, combined with hawkish Federal Reserve communications, have driven the 5-year Treasury yield sharply higher this month. The benchmark climbed above 5% for the first time since 2007, reaching intraday peaks near 5.10% amid weak auctions reflecting elevated supply and fiscal concerns, plus oil-price volatility tied to geopolitical tensions. Real yields accounted for most of the move, signaling repriced growth and policy expectations rather than pure inflation fears. With September nearing its close, the market-implied path now centers on whether further data or central-bank signals sustain or ease these pressures before month-end resolution.
