Tariff threats push U.S. yields higher amid Europe tensions

U.S. Treasury yields climbed after Trump threatened tariffs on eight European allies, fueling fears of a broader trade war and lifting longer-dated notes; the 10-year yield rose to about 4.273%, with the 20-year and 30-year maturities around 4.86% and 4.904%. The dollar index fell nearly 1% as risk appetite wavered, while European leaders signaled countermeasures and Japanese yields rose on a snap election, underscoring rising global funding costs ahead of Davos.
