The 10-year U.S. Treasury yield hit its highest level since 2007 and yields on 10-year German and Japanese government bonds were at multiyear highs. The selloff reflects growing concerns over inflation and central bank tightening, with investors demanding higher returns to hold government debt. U.S. yields climbed above 4.5%, marking their strongest levels in over 15 years, while German bund yields approached 3% and Japanese 10-year yields rose above 0.8% for the first time in years. The synchronized rise across major economies signals a broad reassessment of monetary policy expectations, as markets price in prolonged higher interest rates.

Analysts warn the trend could pressure equity valuations and increase borrowing costs for governments and corporations globally. The move underscores a shift from the low-yield environment that dominated markets for over a decade, with central banks now focused on combating persistent inflation.
