China’s Crude Oil Buying Rebounds, Weakening the Global “China Buffer”

China’s plunging oil imports prevented a bigger price spike after the Iran war broke out, but its crude purchases are now ticking up again

1.    Chinese crude imports show early recovery

o    China is beginning to increase crude oil purchases after several months of subdued imports during the US-Israel war on Iran.

o    The rebound could reduce an important buffer that had helped limit the rise in global oil prices.

2.    August imports rise 6.2%

o    China's crude imports increased 6.2% month-on-month in August to 37.9 million tonnes.

o    This was the highest level in four months, but remained more than 23% below August 2025.

3.    September imports also recovering

o    Kpler estimates China's September crude imports at 7.84 million bpd, compared with 7.25 million bpd in August.

o    However, September imports remain well below the 9.76 million bpd recorded a year earlier.

4.    Shift in sources

o    China's imports from Iraq have surged from 177,000 bpd in August to more than 1 million bpd in September.

o    At the same time, purchases from Iran and Saudi Arabia are expected to decline.

5.    Middle East and Russia supply risks

o    The rebound comes amid renewed supply uncertainty caused by:

§  Attacks on Saudi Arabia's East-West pipeline.

§  Ukrainian attacks on Russia's Novorossiysk export terminal.

o    These disruptions have increased concerns over crude availability and put upward pressure on prices.

6.    China had deliberately reduced imports

o    From April to August, China's crude imports were approximately 3.2 million bpd below the previous year's level.

o    Chinese refiners had been drawing down inventories rather than purchasing aggressively.

o    Growing adoption of new-energy vehicles also reduced oil demand.

7.    The China oil buffer is weakening

o    Chinese crude inventories declined from approximately 1.25 billion barrels in April to 1.14 billion barrels in September, according to Kpler.

o    This reduction means China has less capacity to continue absorbing supply disruptions through inventory drawdowns.

8.    China's renewed buying adds price pressure

o    Analysts said the earlier weakness in Chinese purchases had helped offset part of the global supply shortfall and restrained upward pressure on oil prices.

o    The return of Chinese buyers is now contributing to recent gains in global crude benchmarks.

9.    Large reserves still provide protection

o    China is not expected to return immediately to pre-war import levels.

o    Analysts estimate that existing stocks can cover more than 80 days of demand.

o    Including commercial and strategic reserves, another estimate puts available inventory at around 4–6 months of consumption.

10.  High prices discourage aggressive restocking

o    Brent and WTI rose by more than 20% from late August, approaching US$110/barrel on Tuesday, before falling to around US$100/barrel on Friday.

o    At these prices, Chinese refiners face weaker margins.

11.  Refining margins under pressure

o    Analysts said higher crude prices are eroding Chinese refining margins while domestic product prices are regulated above approximately US$80/barrel.

o    With crude prices remaining above US$100/barrel, Chinese refiners are unlikely to substantially accelerate purchases.

12.  China remains price-sensitive

o    Weak domestic demand and elevated crude prices make aggressive inventory rebuilding less attractive.

o    A prolonged disruption to Saudi exports could further raise crude prices and squeeze Chinese refinery margins.

13.  Possible refined-product response

o    If supply disruptions persist, Beijing could potentially tighten refined-product exports to ensure adequate domestic supplies.

Key Takeaway

China's crude imports are recovering but remain substantially below last year's levels. The decline in Chinese inventories means the “China buffer” against global oil-supply disruptions is becoming weaker. However, substantial remaining reserves and high crude prices are likely to prevent a rapid return to pre-war import volumes.

China is showing early signs of stepping up imports of crude oil after months of subdued buying amid the US-Israel war on Iran, threatening to erode a buffer that has helped prevent a larger surge in global oil prices.

But analysts do not expect China to quickly return to its pre-war import levels, as elevated crude prices could squeeze margins for Chinese refineries and the country’s stockpiles are still large enough to last for several months.

Signs of a rebound in Chinese demand emerged in August, when China’s crude imports rose 6.2 per cent compared with the previous month to hit 37.9 million tonnes, according to Chinese customs data. The figure was the highest import level seen for four months, though still more than 23 per cent lower than a year earlier.

The recovery has continued this month, with China’s crude imports running at 7.84 million barrels per day (bpd) in September, up from 7.25 million bpd the previous month, according to trade intelligence firm Kpler. A year ago, the figure was 9.76 million bpd.

The uptick in Chinese purchases has come amid renewed turbulence in the oil market, as the conflicts in Ukraine and the Middle East cause further disruptions to global supplies. According to Kpler, China’s imports from Iraq shot up from 177,000 bpd in August to over 1 million bpd this month, but its purchases from Iran and Saudi Arabia are set to decline.

“A recent partial rebound in Chinese import demand coincided with increased uncertainty regarding crude oil supply availability from the Middle East – following attacks on Saudi Arabia’s East-West pipeline – and Russia due to Ukrainian attacks on the Novorossiysk export terminal,” said Ivan Ryabov, head of oil trading analytics at Kpler.

“As two major exporters with remaining spare crude production capacity, these disruptions created upwards pressure on prices and raised supply security concerns for importing countries.”

Chinese firms “have held back on buying for several months, but have come back to the market to reduce their drawdown rate and support increased crude runs to replenish domestic product inventory”, said June Goh, a senior oil market analyst at Sparta.

The return of Chinese buyers comes after months of weaker imports, which helped partly offset a global supply shortfall and limit upwards pressure on prices after the outbreak of the Iran war.

China’s crude imports from April to August were about 3.2 million bpd lower than a year earlier, largely because refiners drew on inventories and consumers increasingly switched to new-energy vehicles, according to a report by Huatai Securities published on Tuesday.

But that China buffer is now weakening as inventories fall.

China’s vast crude oil stockpiles have been declining since April, with inventories falling from about 1.25 billion barrels to 1.14 billion barrels in September, data from Kpler showed.

“China’s oil inventories have fallen significantly from the levels built up before the Strait of Hormuz closure, making it harder to sustain the ‘China buffer’ that had helped keep oil prices in check,” the Huatai Securities report said.

Goh agreed that China’s muted crude buying in recent months had helped contain upwards pressure on oil prices, while its return had partly contributed to the recent gains in global oil benchmarks.

“Now, the crude market cannot rely heavily on China to rebalance again,” said Sun Jianan, a senior oil analyst at Energy Aspects.

Even so, analysts do not expect Chinese buyers to return to the market aggressively.

“We see no imminent risk to China’s crude supply,” Sun said, adding that China still had ample crude stocks that could meet more than 80 days of demand and cushion potential supply losses.

Goh estimated that China still had around four to six months of inventory at current consumption rates, when factoring in both commercial and strategic reserves.

Global oil benchmarks such as WTI and Brent rose more than 20 per cent from late August to nearly US$110 a barrel on Tuesday, before falling back to about US$100 a barrel on Friday.

Higher prices are one reason Chinese refiners are unlikely to rush to rebuild inventories.

“Higher crude prices are now eroding Chinese refining margins, as domestic product prices are regulated above US$80 per barrel,” Sun said, adding that he did not expect China to “significantly increase crude purchases with flat prices above US$100 per barrel”.

Similarly, Terine Ooi, associate director of energy markets at Dow Jones Energy, said she did not expect China to quickly return to pre-war import levels.

“Chinese buyers remain highly price-sensitive, particularly when domestic demand is weak,” Ooi said. “At current elevated crude prices, aggressive restocking becomes less attractive and could move the market against China’s own interests.”

A prolonged disruption to Saudi exports could push up crude prices and further pressure refiners’ margins, while Beijing could also tighten refined-product exports to prioritise domestic supply, she added.
