Worries that tariffs could end up driving inflation higher helped push long-term bond yields higher, including the 10-year Treasury, which rose to 4.54 per cent from 4.52 per cent late on Thursday.
โItโs not the safe haven that it normally is because these tariffs might result in higher inflation and the need for the Fed to remain on pause for longer or to reverse course and raise rates,โ Stovall said.
Shorter-term US government bond yields mostly fell.
Yields have been generally climbing since September as the US economy has remained much more solid than economists expected. More recently, worries about tariffs and other possible Trump administration policies that could add upward pressure on inflation and the US governmentโs debt have also sent yields higher.
The Federal Reserve left its benchmark interest rate unchanged as it closed out its most recent meeting on Wednesday. The central bank is signalling a more cautious approach as it waits to see how policies under Trump will impact inflation and the broader economy. Higher tariffs and tax cuts could push inflation higher, while deregulation could possibly reduce it.
โMarkets are on edge watching President Trumpโs plans to raise tariffs and tighten immigration policies, since both are pressuring the Fed to keep interest rates elevated,โ said Bill Adams, chief economist for Comerica Bank.
