The US 30-year Treasury yield has closed above 5% for 14 consecutive sessions, marking its longest such run since July 2007. This year, it has finished above 5% 29 times, the most in any calendar year since 2007. Analysts note this sustained high yield, driven by factors like higher oil prices, strong economic data, and government borrowing, suggests the bond market's previous ceiling is becoming a new floor, increasing competition for stocks and raising borrowing costs.
