Harvest Season to Test Stressed Midwest Fuels Markets

   SECAUCUS, NJ (DTN) -- Heavy agricultural demand for the upcoming Midwest 
harvest is set to severely test a regional fuel distribution network already 
mired in midstream outages, constrained refining capacity and lack of backup 
supply from the Gulf Coast.

   With oncoming agricultural works signaling more diesel consumption, Midwest 
distillate inventories stood at a tight 28.6 million bbl as of the week ended 
August 21, according to Energy Information Administration data.

   Complicating matters is idling of the 1,830-mile Explorer Pipeline carrying 
fuel northward into PADD 2 from the Gulf Coast -- an outage persisting since an 
August 17 explosion and fire at its Glenpool, Oklahoma tank farm hub.

   The lack of a substantial supply cushion leaves regional basis bids acutely 
vulnerable to price spikes at the exact moment that field equipment and heavy 
transport fleets require maximum volume.

   So far in August, Chicago ULSD spot prices jumped 13.7% to $4.0254 gallon 
from July levels, while for Group 3 ULSD spot prices surged 11.8% to $4.0509 
gallon, underscoring the severe monthly cost inflation facing physical buyers, 
DTN data showed.

   A Midwest fuels trader told DTN that the market's physical tightness emerged 
well before the mid-August supply disruptions. Pre-harvest markets typically 
build an inventory buffer in anticipation of peak agricultural burn.

   "If anything, there should be a supply carry heading towards September," the 
trader said. "We didn't see that happening, and we're closing in on the meat of 
harvest season in the coming weeks."

   The absence of a market carry signals that the midstream bottleneck at 
Explorer could place far greater pressure on Midwest refiners to meet surging 
harvest demand.

   Even with refinery runs averaging 4.21 million bpd for August at an average 
run rate of 98.6%, recent EIA data shows regional distillate production topping 
out at 1.29 million bpd. That is against peak harvest distillate demand, 
estimated by analysts at 1.40 million bpd.

   "Reading between the lines, it appears that people in the Midwest are not 
putting out enough product, despite refinery runs being this high," the trader 
noted, adding that the absence of Gulf Coast backup supply further imperiled 
the situation.
