U.S. sovereign bond prices slumped Monday, following a public holiday for the market Friday, as traders continued to eye inflation trends following the election of Donald Trump.

The yield on the benchmark 10-year Treasury note, which moves inversely to its price, moved higher to 2.261 percent, while the yield on the 30-year Treasury bond was higher at 3.01 percent. The benchmark yield also hit its highest level since Dec. 31, 2015 earlier in the session.

Perceived safe havens like fixed income usually suffer when equities are en vogue, and that was the case Monday with global stocks continuing to be buoyed by the result of the U.S. election. Trump's policies are expected to see inflation trending upwards over the coming years which is traditionally bad for bonds.

As a result, the yield on the 30-year U.S. sovereign bond rose above 3 percent and hit its highest since early December 2015. The German 30-year yield topped 1 percent for the first time since early May and the Italian 10-year yield broke above 2 percent for the first time since September 2015.

"The good news about the aftermath of the election result is that we're going to get a change in the global policy order away from solely monetary towards fiscal policy. That's encouraging," Jim Reid, a strategist at Deutsche Bank, said in a note Friday.

On Monday, investors will be able to hear what Federal Reserve members have to say about this new environment for bonds. San Francisco Fed President John Williams is speaking at 6:30 p.m. ET.

There are no economic data of note due out on Monday.
