What specific deadline did the US EPA extend for the 2025 RFS compliance, and what related commitment did it make regarding small refinery exemptions (SREs)?

The US EPA extended the compliance deadline for the 2025 Renewable Fuel Standard (RFS) obligation from the original date of September 1, 2026, and committed to issuing decisions on long-pending small refinery exemption (SRE) applications by the end of August.

Why did the EPA extend the RFS compliance deadline, and what immediate market effect did this announcement have on D6 RIN prices?

The EPA extended the deadline primarily in response to a sharp surge in RIN prices—specifically, biomass diesel D4 RINs reached $2.41 and ethanol D6 RINs $2.37 by June 2026, roughly double their年初 levels and nearing 2021’s historical highs—placing severe compliance cost pressure on refiners like HF Sinclair; following the announcement, D6 RIN prices dropped from a July peak of $2.50 to $1.75, a nearly one-third decline, demonstrating an immediate market reaction to the policy signal.
