After multiple sources told media that U.S. president Donald Trump is considering targeted strikes on Iran's security forces and leaders, West Texas Intermediate settled up $2.21, or 3.5 percent, at $65.42 per barrel. Brent settled up $2.31, or 3.3 percent, at $70.71 per barrel; both benchmarks are now technically in overbought territory. Citi analysts said in a note that further geopolitical escalation could push Brent prices to as high as $72 per barrel over the next three months. Also, conflicting news regarding Kazakhstan's giant Tengiz oilfield, which was forced to close due to a fire and power outage, continued: earlier in the week, sources told media that Tengiz will likely restore less than half its normal production by February 7. On Thursday, Kazakhstan said Chevron would take measures to ensure the reliable and safe operation of the facilities, with the aim of reaching full production in a week.
