SPR posts 14th straight weekly draw as propane inventories stay above seasonal

The Strategic Petroleum Reserve fell again in the week ended June 26, its 14th consecutive weekly draw, per the EIA's Weekly Petroleum Status Report out this morning. That is better than three months of steady withdrawals. Every barrel that leaves the reserve thins the cushion the government keeps against a supply break, and it does so while summer driving demand is building. For jobbers, the takeaway is simple. The federal backstop you count on if a refinery or a pipeline goes down is smaller than it was in the spring.

None of this has forced product prices higher yet. But a shallower reserve gives the market less room to absorb a shock, so a hurricane hit to Gulf refining or an unplanned outage could bite harder than it would have a quarter ago.

Propane build

U.S. propane inventories posted a smaller-than-expected build last week, and stocks are still well above seasonal levels. Production has stayed high, though it has come off the highs seen earlier in June. For anyone selling autogas or lining up winter fill, that mix reads friendly. Plenty of supply in the tanks and heavy output should keep propane well stocked as the summer build runs, which could hold a lid on wholesale costs into the fall.

The number worth tracking is production. It eased this month, and if that softening continues while the seasonal build is supposed to be filling storage, the comfortable picture gets less comfortable.

Capline and Longview

RBN's latest walkthrough of Louisiana refining is a useful reminder of how those plants actually get fed. They pull crude from the Houston and Nederland areas and the broader U.S. Gulf, and they bring barrels in from abroad. Some also take crude piped in from Longview, Texas. Others lean on Capline, which now moves crude south out of Illinois.

Because they can pull from several sources, Louisiana refiners keep making product when any one route tightens. For a fuel buyer in the Southeast pulling from Gulf Coast supply, the health of Capline and the Longview line matters as much as what WTI does on a given morning. When one feed backs up, the refiner has somewhere else to turn, and your rack supply holds.

What to watch

Whether the SPR keeps drawing, and how low the government lets it run before it stops. The propane production trend is the other tell. If output keeps easing into the build season, the current surplus could tighten. And keep an eye on Gulf crude logistics as hurricane season gets going, since a shorter reserve leaves less margin if something on the coast breaks.
