The 10-year Treasury note yield recorded its most rapid one-day increase since April 7, 2025, on Wednesday, and further topped 5.17% on Thursday. John Roque, head of technical analysis at 22V Research, noted that in 16 past instances of rapid yield advances over five decades, financial calamities always followed. Regional bank ETF (KRE) has already fallen nearly 10% from its recent high, and the S&P 500 utilities sector dropped over 4% in the past week. JPMorgan's trading desk advises investors to monitor bond volatility, which is often a greater headwind to stocks than absolute yield levels.
