Hong Kong - Oil is heading for a fifth weekly advance as political upheaval in the world’s biggest crude exporter countered an expansion of US output to the highest level in more than three decades.
Futures were little changed in New York, up 2.5% for the week. Arrests on the weekend of senior Saudi Arabian officials in an anti-corruption probe is seen as consolidating power for Crown Prince Mohammed bin Salman, who supports extending Opec-led output cuts.
While prices eased during the week, record weekly US oil production and a surprise increase in crude stockpiles weren’t enough to peg back on Monday’s 3.1% surge.
Oil is heading for the longest run of weekly gains since October 2016 as global supplies tighten and on signs the Organisation of Petroleum Exporting Countries (Opec) will extend output curbs past the end of March.
Opec this week said US shale production will grow considerably faster than expected over the next four years after cuts triggered a price recovery.
"Political stability was jolted awake this week after Saudi Arabia launched an anti-corruption probe," Daniel Hynes, a Sydney-based analyst at Australia & New Zealand Banking Group, said in a note.
"While the likelihood of a disruption to supply remains low, we believe the events raise the probability of Saudi Arabia taking a more aggressive stance on production curbs.
The risks now lie towards curbs remaining in place longer than expected."
