China’s crude stockpiling rate is one of the most watched numbers in the oil market.

The rate then fell sharply during the mid-2026 Hormuz supply shock, to an estimated 430,000 barrels a day in April as imports slumped, with underlying inventory builds still running near 580,000 barrels a day on some trackers. For the full year, consultancy FGE has estimated a build of about 730,000 barrels a day. Every figure here is an estimate derived from customs, satellite and tanker-tracking data, because China does not publish reserve flows.\"},\"takeaways\":[\"The rate was not constant. It ran near 1.24 million barrels a day early in 2026, then dropped to roughly 430,000 barrels a day by April as the Hormuz crisis cut imports.\",\"Different trackers disagree because none see the real number. Estimates for 2026 range from about 430,000 barrels a day in the weakest month to a full-year average near 730,000 barrels a day.\",\"The build is measured indirectly: apparent supply (imports plus domestic output) minus refinery runs. That residual is what analysts call stockpiling, and it carries real error bars.\",\"By April 2026, aboveground crude stocks reached an estimated record 1.24 billion barrels, on top of state reserves and expanding storage capacity.\",\"The pace is a commercial signal.

State companies including Sinopec and CNOOC are adding at least 169 million barrels of storage capacity across eleven sites through 2025 and 2026, explicitly framed as lifting reserves toward three months of net import cover, so the capacity to keep buying is expanding even when the pace pauses.\"]},{\"id\":\"commercial\",\"q\":\"What does the pace signal commercially?\",\"h\":\"The Fill Rate Is a Price Floor You Can Read\",\"p\":[\"For anyone selling into or pricing off the oil market, China's fill rate is a leading indicator.

China does not publish stockpiling flows, so analysts infer them from apparent supply, which is imports plus domestic production, minus refinery runs. Different assumptions about refinery throughput and unreported barrels produce different rates, which is why a single month can be quoted as 430,000 or 580,000 barrels a day.\"},{\"q\":\"Why did China slow its buying in April 2026?\",\"a\":\"Because prices rose during the Hormuz supply shock and China chose not to chase them.
