The Narrative Of Energy Inventories

While there is a direct relationship between the steepness of contango in the oil futures curve and the amount of crude siphoned from the market to storage, it is not an immediate one. When crude prices originally collapsed starting in late 2014, twisting the WTI curve from backwardation to so far permanent contango (of varying degrees), it wasn’t until January 2015 that domestic inventories began their surge. And while oil prices rose through spring, flattening out again the futures curve and drastically reducing that contango, the spike in oil stocks didn’t actually end until almost the end of last April.

Given the “dollar’s” explicit seasonality, combined with the usual intra-year swings of crude itself, it isn’t surprising to find the process repeated almost exactly a year later. This time it happened in two separate events, the latter of which was a near replica of the start to 2015. The futures curve was pressed into deep contango after October 2015, and sure enough oil inventories spiked again in early January 2016. And like last year, though the futures curve would begin to flatten out again starting February 12, oil storage levels continued to build until the end of April.
