US diesel price up 70% since US-Israel war with Iran began

The policy response is the real signal here: releasing reserves and easing dyed-diesel rules address crude and retail margins, not the refined-product bottleneck that is actually driving the move. That distinction matters because the burden lands on farmers and truckers, who cannot pass costs through as easily as larger operators, and because the tax and logistics friction keeping retailers from adopting dyed diesel suggests the relief is narrower in practice than on paper. The open question is whether the administration shifts toward measures aimed at refining capacity rather than inventories.
