U.S. commercial crude oil inventories fell by 8.6 million barrels to 415.6 million barrels in the week ended October 9, as lower imports, reduced domestic production and increased refinery processing tightened the country’s reported crude balance, according to data released Thursday by the U.S. Energy Information Administration (EIA).
The decline brought crude inventories approximately 3% below their five-year seasonal average. However, the broader petroleum picture was mixed: gasoline stockpiles increased by 3.5 million barrels, while distillate inventories fell by 2.5 million barrels.
The EIA’s weekly report, published October 15, showed commercial crude stocks declining from 424.134 million barrels to 415.577 million barrels. The 8.557 million-barrel reduction rounds to the agency’s headline figure of 8.6 million barrels.
Lower Imports Deepen Drawdown
U.S. crude oil imports averaged 6.049 million barrels per day during the reporting week, down 791,000 barrels per day from 6.840 million barrels per day in the preceding week. That decline reduced the volume of foreign crude entering the domestic supply system at the same time that U.S. refineries processed more oil.
Domestic crude production also fell, declining by 300,000 barrels per day to an estimated 13.679 million barrels per day from 13.979 million barrels per day. Together, the lower production and import figures indicate a substantial reduction in incoming crude supply. But imports alone do not explain the entire inventory movement.
Exports, refinery activity, inventory transfers and statistical adjustments are also important parts of the weekly petroleum balance. Crude exports decreased to 4.570 million barrels per day from 4.765 million barrels per day, partly offsetting the effect of lower incoming supply.
The reduction in weekly production should not automatically be interpreted as a permanent decline in U.S. output, because the EIA’s weekly production figures are estimates subject to subsequent data updates and benchmarking.
Refineries Increase Crude Processing
U.S. refineries processed an average of 16.615 million barrels of crude per day, an increase of 135,000 barrels per day from the preceding week’s 16.480 million barrels. Refinery utilization increased to 93.5% from 92.7%, a rise of 0.8 percentage points.
Higher refinery processing means more crude oil was being converted into transportation fuels and other petroleum products during the week. Combined with lower crude imports and production, this provides a clearer explanation for the sharp reduction in crude stockpiles.
The EIA supply estimates also showed that inventories declined despite lower crude exports. That distinction matters because a drawdown driven partly by stronger refinery processing has a different interpretation from one caused entirely by unusually strong crude exports or a sustained loss of domestic production.
The report establishes a significant weekly tightening in commercial crude inventories, but a single week’s results cannot determine whether the decline will persist.
Gasoline Stocks Rise Sharply
The largest divergence in the report occurred between crude inventories and refined petroleum products. Total motor gasoline inventories rose to 208.262 million barrels from 204.744 million barrels, an increase of approximately 3.5 million barrels. Despite that increase, gasoline inventories remained about 4% below their five-year seasonal average, according to the EIA.
Distillate fuel inventories, which include diesel and heating oil, moved in the opposite direction, falling to 102.611 million barrels from 105.138 million barrels. That decline of approximately 2.5 million barrels left distillate inventories 12% below their five-year seasonal average. The contrast is significant. Crude oil inventories provide information about unrefined supply available to the petroleum system, while gasoline and distillate stocks provide separate indicators of the availability of finished fuels.
Gasoline inventory growth does not necessarily imply stronger consumer demand. The EIA reported that gasoline product supplied averaged 8.7 million barrels per day over the latest four weeks, down 0.4% from the comparable period a year earlier. Distillate product supplied averaged 4.0 million barrels per day over four weeks, down 0.2% year over year.
These demand-related measurements are four-week averages, not changes from the preceding week, and should not be interpreted as direct explanations of the latest weekly inventory movements.
Broader Petroleum Stocks Decline
Total commercial petroleum inventories, excluding the Strategic Petroleum Reserve, declined by approximately 13.4 million barrels during the week. The EIA’s inventory series shows total crude oil and petroleum product stocks excluding the reserve falling from 1.2374 billion barrels to 1.2240 billion barrels.
The reduction was broader than crude oil alone, even though gasoline inventories increased. The Strategic Petroleum Reserve remained unchanged at approximately 283.0 million barrels. Its holdings are reported separately from commercial crude inventories and should not be included in the 8.6 million-barrel commercial drawdown.

Another measure of underlying activity showed total petroleum products supplied averaging 21.1 million barrels per day over the previous four weeks, 2.0% above the same period in 2025. That broader increase contrasts with the weaker year-over-year readings for gasoline and distillate separately, illustrating why the different petroleum demand indicators should not be treated as interchangeable.
The latest data also comes amid substantial oil supply risks related to Middle East shipping and energy flows. Nevertheless, the domestic inventory report alone cannot establish how much of an oil price movement is attributable to U.S. stock levels rather than geopolitical developments or changes in global supply expectations.

U.S. Petroleum Inventory Drawdown: Independent Calculation
U.S. commercial crude inventories declined by 8.557 million barrels in the week ended October 9, 2026. Investozora's calculations show that this represented a 2.02% reduction from the preceding week's inventory level. Crude accounted for approximately 63.9% of the broader decline in commercial petroleum inventories, excluding the Strategic Petroleum Reserve.
Inventory Reconciliation by Category
The following comparison uses reported end-of-week stock levels. All values are expressed in millions of barrels. Negative changes indicate inventory declines.
| Category | Oct. 2 | Oct. 9 | Change |
|---|---|---|---|
| Commercial crude | 424.134 | 415.577 | −8.557 |
| Motor gasoline | 204.744 | 208.262 | +3.518 |
| Distillate fuel | 105.138 | 102.611 | −2.527 |
| Strategic reserve | 282.983 | 282.983 | 0.000 |
| Total excl. SPR | 1,237.400 | 1,224.016 | −13.384 |
What the Reconciliation Reveals
Crude oil represented approximately 63.9% of the total commercial petroleum inventory decline. The remaining net reduction was approximately 4.827 million barrels, or 36.1%, across petroleum products and other non-crude stock categories combined.
This residual is calculated by subtracting the crude inventory decline from the total commercial petroleum decline. It should not be confused with the sum of gasoline and distillate movements alone, because the total also includes other petroleum product categories.
Gasoline inventories increased by 3.518 million barrels while distillate stocks declined by 2.527 million barrels. Their combined net movement was a 0.991 million-barrel increase. Other non-crude categories therefore accounted for an implied net decline of 5.818 million barrels.
These figures describe changes in inventory holdings, not independently established causal contributions from imports, exports, production or refinery activity. The stock comparison alone cannot identify which flow caused each movement.
Calculation Method and Limitations
Investozora calculated absolute inventory changes by subtracting the October 2 stock level from the October 9 stock level. Percentage changes use the October 2 level as the denominator. The crude share of the total decline divides the absolute crude drawdown by the absolute total commercial petroleum drawdown.
Stock values are expressed in millions of barrels, not barrels per day. All comparisons use the same two reporting weeks and geographic coverage. Calculations use the displayed EIA stock figures, with percentages rounded to two decimal places for the crude decline and one decimal place for inventory shares.
Total commercial petroleum stocks exclude the Strategic Petroleum Reserve. The component categories shown above are not exhaustive and must not be summed as though they constitute the entire commercial petroleum inventory. EIA weekly figures are estimates and may subsequently be revised.

What Comes Next
The October 15 release showed a substantial weekly contraction in U.S. commercial crude inventories, with lower domestic production, reduced crude imports and higher refinery processing all contributing to tighter reported balances. But the increase in gasoline stocks and continued weakness in some fuel-demand indicators complicate any straightforward conclusion that overall petroleum demand is accelerating.
The EIA's next Weekly Petroleum Status Report is scheduled for Wednesday, October 21, 2026, at 10:30 a.m. Eastern Time, covering the week ending October 16. That release will provide the next indication of whether the crude inventory decline continues, whether production and imports recover, and whether the divergence between gasoline and distillate inventories persists.
