After the shale production revolution, U.S. propane supply began to exceed domestic demand, turning the U.S. into a net exporter of propane. Consequently, propane’s value relative to crude began to fall consistently below its previous 70 percent relative valuation benchmark.
Propane’s average value to crude has been 50 percent in the past 10 years, reflecting the increased abundance of propane. Currently, propane is well below the 10-year average at 33 percent. It is unusual for propane to be valued this low relative to crude during this time of year. In fact, propane is setting new lows each week for this time of year, but it is still above its all-time low of 24 percent set in 2015. That also happens to be the year propane set its all-time highest inventory level of 102.804 million barrels. Currently, propane inventories are less than 500,000 barrels below that record with potential to increase more.
