Concerns over deepening trade tension between US and China sent oil prices down today. Brent crude oil futures fell by 0.2% to $77.93 per barrel. US West Texas Intermediate (WTI) futures dropped by 0.3% to $68.79 a barrel. If sources were to be believed, the US is planning to impose tariffs on about $200 billion on Chinese imports, and an announcement regarding the same might come on Monday.
