Heating oil stocks rose 10,000 barrels in the week to Sep 4, EIA reports, reversing prior draw
The EIA put US distillate heating oil stocks up by 0.010 million barrels in the week to September 4, a small build that flips the prior week's draw of 0.033 million barrels. Ten thousand barrels either way is noise. What matters heading into fall is direction, and for one week the direction turned from drawing down to adding.
For jobbers watching heating oil supply into the Northeast, a build this early is the outcome you want. It says refiners and blenders are putting product into tank rather than pulling it, which is normal for September but worth confirming week to week as heating demand starts to show up.
Read the two prints together and the takeaway is modest. A 43,000-barrel swing from a draw to a build, on a base measured in the tens of millions of barrels, does not tell you much about where winter inventories land. It tells you the trend paused. One weekly number is a data point, not a season.
The propane PDH forecast
A market research note from IndexBox projects the propane and liquefied gas market growing through 2035, with propane dehydrogenation capacity, PDH, cited as the driver. PDH plants crack propane into propylene, a petrochemical feedstock, so every new unit is a standing buyer of propane that competes with the guy filling home tanks and grain dryers.
US operators should watch this part. The US is a large propane exporter, and new PDH capacity, whether built here or abroad, could tighten the propane balance that retail and ag customers draw from. If the forecast plays out, propane demand may firm on the petrochemical side regardless of what a mild or cold heating season does to residential draw.
The 2035 horizon is a long-dated forecast from a research firm, not a supply commitment, and PDH projects slip. It does not change what a propane retailer pays this month. It does flag that the demand pull on propane could keep growing from a source that has nothing to do with weather.
What to watch
Next week's EIA distillate print, to see whether the small heating oil build holds or the draw resumes as the calendar moves toward heating season. One build does not make a trend.
On propane, watch physical inventory and export numbers over the near term rather than the 2035 forecast. If PDH demand is real and growing, it should start showing in tighter propane balances and steadier export volumes, and that is where a retailer would feel it first.
