Oil hit a three-year high above $86 a barrel yesterday driven by tight supply and a global energy crunch, although prices eased as some investors took profits on signs the rally is looking overstretched.

Helping to drive the latest gain, a supply report from the U.S. Energy Information Administration on Wednesday showed crude and fuel inventories tightened, with crude inventories at the Cushing storage hub falling to a three-year low.

Brent crude rose as high as $86.10, the highest since October 2018, but was down 92 cents by 1.1 per cent, to $84.90. United States (US) West Texas Intermediate crude fell 74 cents, or 0.9 per cent, to $82.68.

“Traders who had set $86 as their selling threshold took the opportunity to already pocket some profit. Oil prices took a dive as a result,” Louise Dickson of Rystad Energy said.

The price of Brent has risen over 60 per cent this year, supported by a slow ramp-up in supply by the Organisation of the Petroleum Exporting Countries and allies, and a global coal and gas crunch which has driven a switch to oil for power generation.

Oil also came under pressure from a drop in coal and natural gas prices. In China, coal fell 11 per cent on Thursday, extending losses this week since Beijing signalled it might intervene to cool the market.

“With coal and gas prices easing and with the relative strength index technical indicators still in overbought territory, the odds of a sharp, but material fall in oil prices are rising,” Jeffrey Halley, analyst at brokerage OANDA said.

Even so, some analysts are calling for oil to rally even more as OPEC+ is likely to stick to its plan for gradual output increases while demand is expected to reach pre-pandemic levels.

Rystad said the outlook was bullish for the rest of the year and Giovanni Staunovo of Swiss bank UBS said in a report he expected Brent to trade at $90 in December and March.
