More jet fuel has been in U.S. West Coast inventories than over the previous five years for 29 out of 35 weeks so far in 2024, according to our Weekly Petroleum Status Report (WPSR). High inventories helped reduce Los Angeles regional crack spreads for jet fuel to an average of 5 cents per gallon (gal) in August, lower than any point in the last five years, including during the onset of the COVID-19 pandemic in 2020. Crack spreads represent the price difference between products and crude oil and can be used to determine the relative value of various petroleum products for refineries to produce.
