U.S. Treasury yields rose on Thursday morning, as traders and investors dump bonds following President Donald Trump's latest round of proposed tariffs on automobile imports.

The benchmark 10-year Treasury yield (US10Y) hit a session high at 4.40%, marking its highest level since February 24. It was last up 3 basis points to 4.36%. 

The selling of bonds reflects growing unease over the impact of tariffs on the broader economy. With traders adjusting their portfolios, the climb in yields signals a shift in market sentiment, as investors price in potential economic disruptions from the proposed trade measures.    

Other longer-duration U.S. Treasury yields were also higher. The 30-year yield (US30Y) hit a session high at 4.76%, its highest level since February 21. It was last up 3 basis points to 4.72%. 

Another notable trend in the Treasury market is the steepening of the yield curve. The spread between the US10Y and the shorter-end 2-year Treasury yield (US2Y) hit its steepest level since January 24, widening to +0.26%.
