05:38 AM EST, 11/17/2025 (MT Newswires) -- Crude oil prices declined on Monday after a key Russian export hub resumed operations following a Ukrainian drone attack.

Brent crude at last look fell 0.7% to US$63.93/barrel and West Texas Intermediate crude lost 0.8% to $59.59/b. The losses erased the previous week's gains from the suspension of loadings at the Novorossiysk port and a neighboring Caspian Pipeline Consortium terminal, which affected an estimated 2% of global supply, Reuters said in a Monday report.

Novorossiysk port resumed oil loadings on Sunday. However, Ukraine's continued attacks on Russian energy infrastructure still pose supply risks, the report said, noting attacks on Russia's Ryazan oil refinery and the Novokuibyshevsk oil refinery over the weekend.

"Investors are trying to gauge how Ukraine's attacks will affect Russia's crude exports in the long term, while also locking in profits after last Friday's rally," Reuters quoted Toshitaka Tazawa, an analyst at Fujitomi Securities, as saying.
