We forecast retail gasoline and diesel prices will decline in 2023 and 2024, according to our latest Short-Term Energy Outlook (STEO), after reaching multiyear highs in the first half of 2022. We forecast that retail prices for regular-grade gasoline will average $3.32 per gallon (gal) in 2023 and continue to decrease to average $3.09/gal in 2024, down from $3.96/gal in 2022. We expect on-highway diesel prices to decrease to average $4.23/gal in 2023 before decreasing further to $3.70/gal in 2024. These forecast price decreases are based on our expectation of lower demand growth for diesel and motor gasoline with continued high production of those products.
