'Only happened a handful of times': Analyst sounds alarm at rare economic 'red flag'

A massive sell-off in U.S. bonds led a CNN analyst to sound the alarm about a rare "red flag" as financial markets reel.

The country saw a significant sell-off in U.S. bonds this week, driven by concerns over President Donald Trump's tariff policies and broader economic uncertainty. The yield on the 10-year Treasury note surged to as high as 4.53%, marking its highest point since February and a dramatic increase from Monday’s low of 3.87%. This reflects a sharp decline in bond prices, as yields and prices move inversely.
