Oil prices climb more than 3% amid robust demand and tighter supplies

MELBOURNE (Reuters) -Oil prices climbed on Friday, heading for gains of more than 3% for the week, on increasing signs of robust demand and tighter supplies over the next few months as rocketing gas and coal prices stoke a switch to oil products.

Brent crude futures touched their highest since October 2018, rising 84 cents, or 1%, to $84.84 a barrel by 0652 GMT. Front-month prices are set to climb for the sixth straight week, up 3% this week.

U.S. West Texas Intermediate (WTI) crude futures rose 74 cents, or 0.9%, to $82.05 a barrel, adding to an 87 cent jump on Thursday. The contract is heading for a 3.4% gain on the week, up for the eighth consecutive week.

Analysts pointed to a sharp drop in OECD oil stockpiles to their lowest level since 2015. Demand has picked up with the recovery from the COVID-19 pandemic, with a further boost coming from industry turning away from expensive gas and coal to fuel oil and diesel for power.

"The fact that Asian markets are content to chase prices higher at weekly highs, instead of lurking on price dips, is a strong signal that energy demand remains robust," OANDA senior analyst Jeffrey Halley said in a note.

The International Energy Agency on Thursday said the energy crunch is expected to boost oil demand by 500,000 barrels per day (bpd).

That would result in a supply gap of around 700,000 bpd through the end of this year, until the Organization of the Petroleum Countries and allies, together called OPEC+, add more supply, as planned in January.

"This energy crisis, particularly in coal and gas, has really pushed up the energy complex higher and oil has benefited as a result," said Commonwealth Bank commodities analyst Vivek Dhar.

"You're looking at a narrow window where things can tighten considerably, but it's going to be very weather-dependent," Dhar said.

RBC Capital Markets analysts said the global oil market is shaping up for a strong bull cycle, led by supply tightening and demand strengthening at the same time.

"We maintain the view that we have held all year - that the oil market remains in the early days of a multi-year, structurally strong cycle," RBC analyst Michael Tran said in a note.

Investors shrugged off a higher than expected gain in U.S. crude stocks last week as refinery crude runs fell.

Crude inventories rose by 6.1 million barrels in the week to Oct. 8 to 427 million barrels, compared with analysts' expectations in a Reuters poll for a 702,000-barrel rise, the Energy Information Administration said on Thursday.
