Counter-Seasonal Whipsaw - Mont Belvieu Propane Soars Over Conway

A blast of Arctic air plunges the Midwest and Northeast into deep freeze. Already-low propane inventories result in supply shortages in local markets. Propane transport trucks move product hundreds of miles from storage hubs to replenish regional terminals as markets scramble to meet surging propane demand. Are we talking about the nightmarish polar vortex winter of 2013-14, when regional propane inventories were sucked down dangerously low and Conway, KS, propane prices skyrocketed to almost $5.00/gal? No. We are talking about now. This is a description of what is happening today in U.S. propane country –– that belt of northern states that depend heavily on propane for heating. But this is not 2013-14. Things have changed.  So in today’s blog we’ll explore how the latest polar vortex could be quite different than that weather-driven crisis seven years ago.

The official start of propane heating season is only two months away, and inventories are skinny, pretty close to the five-year minimum. Should that be a concern? After all, stocks were at the low end of the range last year, and it was a relatively benign market, with few supply chain disruptions. But there’s a potential gotcha in that statement. Because last year the first three months of winter were quite mild in propane country. What would happen if the market were hit with weather events like what we saw during the “polar vortex” of 2013-14, a winter etched into the minds of all propaners who lived through it? Obviously, the outcome would be quite different.  In today’s RBN blog, we continue our series on the upcoming propane heating season with a look at the challenges that unusually cold weather could bring.

For 10 years prior to 2018, the differential between propane prices at the Conway, KS, hub averaged less than a nickel per gallon below Mont Belvieu. In fact, between 2013 and 2017, the price spread was only 3.5 c/gal — excluding a winter 2014 Polar Vortex aberration — which basically reflects the cost of moving barrels 700 miles north-to-south. Not this year, though. After starting 2018 at 3 c/gal, the propane price spread took off, and has averaged 18 c/gal since April, some days moving above 26 c/gal, far above the per-bbl cost of transporting propane 700 miles south to Mont Belvieu. Is it pipeline capacity constraints? In part. But there is a much more significant factor driving this differential wider, not only in the propane market, but across all five of the NGL purity products. What is this mysterious factor? To find out, read on. But here’s your first clue: the problem is not in Kansas anymore.
