10-year bond yields now track diesel prices more than crude, but Trump's fuel moves may fall short

For the first time on record, 10-year Treasury bond yields are tracking diesel prices more closely than crude oil, a shift highlighting that refined fuel costs, not crude, are now the primary driver of inflation expectations and market behavior. This development comes as the Trump administration takes emergency measures to lower diesel prices ahead of the midterm elections. Diesel remains 71% above year-ago levels at $6.277 per gallon, despite easing from its all-time high, with the surge hitting manufacturing, agriculture, and logistics. President Trump has signed an executive order deferring the 24-cent federal diesel tax and announced a deal with Vladimir Putin for Russian diesel supplies, though experts say both moves will provide minimal relief given the $2.60 per-gallon annual increase and the global nature of fuel markets. Analysts note the breakdown in the traditional crude-refined product price relationship, with diesel now a better gauge of inflationary pressure and Fed policy expectations. However, a Politico poll shows that even significant fuel price drops would likely not sway undecided voters, with only 10% saying a $1 per gallon decrease would make them more likely to support Republicans.
