China has spent around $24 billion on building its crude reserves since 2015, at an average of $50 a barrel, and now holds around 850 million barrels of oil in inventory. The United States is not party to the deal, and its crude output has risen 10 percent this year to more than 9.5 million bpd.
"China has played a major role in global crude oil markets by helping to clear most of the excess seen in the last two to three years, which puts an even greater importance on understanding better, but also scrutinising the Chinese data", the IEA said in its monthly oil market report. U.S. crude supplies fell by 2.75 million barrels last week, according to Energy Information Administration (EIA) data on Thursday. Analysts had expected a draw of 2 million barrels. Last week, US refineries ran at 89 percent of operating capacity, up from a low of 77 percent in early September.
Earlier in the week, oil prices were pressured by a government report that showed USA fuel inventories rose despite efforts by OPEC to cut production. The IEA said the string of hurricanes that slammed into the US was partially to blame for the decline in the third quarter.
