Propane storages in the East started July higher at 369.5, commensurate with 2.328 MMbbl. This gain put propane 131.8 Mcm, or 55.45%, higher for the month, with a decrease of 22.4, or 5.72% below a year earlier. 

Canadian butane inventories stood at 990.9 Mcm at the beginning of July, for an increase of 213.7 Mcm, or 27.5%, from June. Like propane, the year-over-year comparison finds butane volumes to be lower than the prior year's total, with inventories 50.2 Mcm, or 4.82%, below 2022.  

Western butane supplies, at 570.2 Mcm, were higher by 60.4 Mcm, or 11.85%, from the previous months and were 83.7 Mcm, or 12.80%, less than last year. Eastern butane, at 420.7 Mcm, was 153.3 Mcm, or 57.33%, higher month over month, and totaled 33.5 Mcm, or 8.65%, above a year earlier.
