30-Year Treasury Yield Surge Sparks Market Turmoil Amid Trump Tax Bill Fallout
The 30-year US Treasury yield climbed to an 18-year high, rattling Wall Street as President Donald Trump’s tax bill passage coincided with a Moody’s credit downgrade. Bond markets bled into equities, erasing 800 points from the Dow Jones Industrial Average in a 1.9% collapse.
Long-dated Treasuries breached the psychologically significant 5% threshold for consecutive sessions, with the 30-year settling at 5.088%. The parallel 15-basis-point spike in 10-year yields suggests structural repricing rather than temporary volatility.
