Benchmark pipeline CBOB at Chicago found a double-digit discount to gasoline futures Tuesday for the first time since June 22 on a selloff that market players said took Upper Midwest gasoline toward more typical differentials for mid-December.
CBOB on the West Shore pipeline from the city into eastern Wisconsin fell 5.25 cents/gal to the NYMEX January RBOB futures contract minus 10.25 cents/gal with bids heard at 15 cents/gal under futures.
The day-over-day drop in the differential was the largest since CBOB fell the same amount October 2.
BP said last week its 413,500 b/d Whiting, Indiana, refinery was back to normal operations after six weeks of planned work on a coker and crude unit. Whiting is the largest refinery in the Midwest and sixth largest in the US.
On November 2, CBOB was assessed 10.5 cents/gal over futures, meaning it has fallen at a rate of 79 points per trading day since then.
In mid-December 2017, Chicago differentials venture into positive territory as crude diluent for Canada occupied space on the Explorer Pipeline running northward through Illinois. But in mid-December 2016, the differentials were 5-10 cents/gal below futures.
The big dip Tuesday supported the story line that the Chicago market is historically prone to large swings.
