Oil prices rose at the close of trading today, Sept. 15, amid investor concerns about the impact of Ukrainian attacks on Russian refineries and US President Donald Trump's call for NATO countries to stop purchasing Russian oil.

Brent crude futures for November delivery rose 0.67%, or 45 cents, to settle at $67.44 a barrel.

WTI crude futures for October delivery rose 0.97%, or 61 cents, to settle at $63.30 a barrel.

Ukraine launched a massive attack using at least 361 drones targeting Russian refineries, causing a brief fire at the Kirishi refinery in northwestern Russia, Russian officials told Reuters.

Meanwhile, HSBC warned that Brent crude prices could fall below its current forecast of $65 per barrel in 2026 due to rising inventories and a surplus in the oil market in the fourth quarter of this year.
