Medium and long-term U.S. bond yields have risen to levels not seen since September of last year, with the 30-year bond yield increasing by more than 0.09 percentage points to surpass 4.93%, while the 10-year bond yield reached 4.3%. This rise followed the sharp decline in Japanese bond markets, which extended its impact to global financial markets. These levels, not recorded since early September of last year, reflect a noticeable shift in investor sentiment and their reassessment of interest rate and inflation outlooks in the U.S. economy.
