Oil prices fell more than 1% on Thursday, extending the previous session’s 3% drop, pressured by mounting recession concerns and a surprise boost in U.S. crude inventories.

In a sign of investor concern that the world’s biggest economy could be heading for recession, weighing on oil demand, the U.S. Treasury bond yield curve inverted on Wednesday for the first time since 2007.

China’s threat to impose counter-measures in retaliation for the latest U.S. tariffs on $300 billion of Chinese goods also weighed on oil prices.
