SignalTrace interpretation · Current event

Refinery product mix, storage locations and actual demand stand between crude oil and finished products. A rise in crude inventories alone does not show that product-specific supply constraints have eased.

U.S. commercial crude inventories rose slightly in the week ended August 21. Gasoline and distillate inventories fell, remaining below their averages for the same time of year over the past five years.

SignalTrace interpretation · Current event

The transmission runs from crude supply through refinery inputs and product mix, then through regional storage and transport demand. More crude in storage therefore does not mean every petroleum product is in ample supply.

We weaken the divergence interpretation if the next report shows distillate inventories recovering while refinery output stays similar. One week of data does not establish company outcomes.

Refinery throughput and product mix determine how much crude supply becomes product supply. Check inputs and utilization, product mix and outages, then inventories and cash flow. We weaken the interpretation if official throughput and inventory evidence do not confirm the channel.

Distillate supply connects petroleum supply to freight and industrial activity. Assess distillate inventories alongside transport volumes, fuel use, utilization and cash flow. We weaken the interpretation if official demand and operating evidence do not confirm the channel.

Official source fact · Historical context

The official tables separate inventories by region and product, so national totals cannot represent supply in every region.
