US midcontinent diesel inventories sank to a 90-month low last week as farmers wrap-up planting the biggest corn crop in 12 years.
Midcontinent diesel stocks in the week ended 23 May fell to 22.9mn bl, the lowest since 17 November 2017, according to US Energy Information Administration (EIA) data.
Diesel inventories fell by 3.4pc from the prior week and have been declining since the week ended 21 February when volumes were at 34mn bl, a 33pc decline over that span.
Regional diesel production fell last week by 2pc to 1.16mn b/d following three consecutive weekly gains.
Despite low stocks, Group Three ultra-low sulphur diesel (ULSD) prices continue to fall, indicating weakening demand. Prices closed at $2.01/USG on 29 May, the lowest since 7 May and 31¢/USG lower than a year earlier. Cash prices peaked on 14 May at $2.23/USG and have steadily declined since then.
US farmers are expected to plant 95.3mn acres of corn this spring, up by 5.2pc from last year, the US Department of Agriculture (USDA) predicted in its 31 March prospective planting report. That would be the highest corn acreage since 2013.
US corn planting, a proxy for diesel demand, was 87pc complete in the week ended 25 May, 2 percentage points ahead of the five-year average pace, according to the USDA. Missouri was 94pc complete, ahead of last year's 88pc pace. Corn planting in Illinois and North Dakota also were outpacing last year with 82pc and 78pc completed, respectively.
In Chicago, diesel prices have climbed in the past two sessions, even as spring planting winds down.
West Shore/ Badger pipeline ULSD was at $1.98/USG on 29 May, the highest since 23 May, while Buckeye Complex and Wolverine pipeline ULSD closed at $2/USG, also the highest since 23 May. Prices for West Shore/Badger ULSD were down by 19¢/USG from a year earlier, while Buckeye Complex and Wolverine ULSD were down on the year by 17¢/USG.
