China unexpectedly added 210,000 barrels per day to its crude oil stockpiles in July as weak refinery processing outweighed a sharp drop in imports.
The Bottom Line
- Inventory Rebound: China built a surplus of 210,000 bpd in July, shifting away from draws of 940,000 bpd in June and 500,000 bpd in May.
- Refining Cuts: Total crude throughput dropped 15.8% year-over-year to 12.51 million bpd, actively balancing lower import volumes.
- Export Shifts: Beijing restricted fuel exports to ensure domestic supply security, setting up potential market pressure as restrictions ease in August.
Decoding China’s Crude Balance Sheet in July
Here is the math behind the July numbers. China imported 8.41 million bpd of crude while domestic output added roughly 4.3 million bpd, giving refiners a total available pool of 12.72 million bpd, according to hydrocarbonprocessing.com. But the balance sheet tells a different story on the demand side.
Refinery throughput hit 12.51 million bpd. Subtracting that processing volume from total availability leaves an unexpected daily surplus of 210,000 barrels. For the first seven months of the year, China has accumulated about 480,000 bpd in total inventories, anchored by strong import volumes during the first quarter.
Navigating the Strait of Hormuz Supply Shock
Since attacks began in the Strait of Hormuz following military escalations involving the U.S., Israel, and Iran on February 28, global seaborne flows have faced heavy constraints. Prior to the conflict, nearly 20% of the world’s crude passed through the waterway.
Even optimistic U.S. government estimates point to a sustained loss of roughly 5 million bpd from the Middle East. Seaborne arrivals into China have hovered well below historical averages, with June hitting a decade-low of 7.12 million bpd before ticking up to 8.41 million bpd in July, according to customs figures reported by hydrocarbonprocessing.com.
Managing Throughput Versus Fuel Exports
Instead of aggressively tapping its strategic and commercial stockpiles—estimated to contain at least 1.2 billion barrels—Beijing adjusted domestic levers. Refiners dialed back processing rates, yet kept them high enough to satisfy domestic demand.
At the same time, Beijing choked off refined product shipments. July exports reached 4.65 million metric tons, keeping total fuel shipments down 13.1% to 28.25 million metric tons across the first seven months of the year. By restricting exports, refiners preserved crude inventories without draining reserves.
| Metric | Volume (bpd or % change) |
|---|---|
| Crude Imports | 8.41 million bpd |
| Domestic Production | 4.3 million bpd |
| Refinery Throughput | 12.51 million bpd (Down 15.8% YoY) |
| Implied Monthly Surplus | 210,000 bpd |
Forward Guidance as August Export Curbs Ease
Market watchers are now turning their attention to August adjustments. Beijing is easing fuel export restrictions for a second month in August, allowing refiners to capture elevated regional refining margins for diesel and gasoline across Asia.
According to estimates from commodity analytics firm Kpler, seaborne crude imports for August are projected near 7.0 million bpd. Whether increased product exports force Beijing to resume heavy crude buying—thereby putting upward pressure on global benchmark prices—remains the key variable for Q3 market direction.
