U.S. refiners are short on $1.6 billion worth of credits they need to comply with U.S. biofuel laws. Reuters reviewed corporate earnings disclosures to come up with that total. The big liability comes as the Biden Administration considers potential relief for oil refiners from biofuel mandates. Refiners say they need the relief because of soaring credit costs and the economic hardship brought on by COVID-19 that’s hurt the industry. RIN prices are higher since the start of 2021 because of higher feedstock costs and market uncertainty. RINs were trading at the highest price since the program began 13 years ago. Prices have dropped 50 cents since hitting a recent high of $2 a credit. If the Biden administration grants some relief from the mandates, refiners may not need to fulfill all their obligations. Some lawmakers and refining industry representatives have requested help for the industry. The White House hasn’t said what actions President Biden will take to relieve refiners of their obligations under the Renewable Fuel Standard.
