Oil prices fall into bear market on rising supply, economic concerns

By Henning Gloystein

SINGAPORE (Reuters) - Oil markets on Friday remained weak as rising supply and concerns of an economic slowdown pressured prices, with U.S. crude now down by around 20 percent since early October.

U.S. West Texas Intermediate (WTI) crude oil futures were at $65.60 per barrel at 0509 GMT, down 4 cents, or 0.1 percent from their last settlement. WTI is set to fall for a fifth week, down 4.1 percent so far this week.

Front-month Brent crude oil futures were at $70.69 a barrel, 4 cents above their last close. Brent is set for a 2.9 percent drop for the week, its fifth straight week of declines.

Both Brent and WTI have declined by around 20 percent from the four-year highs they reached in early October.

"Oil prices continue to decline and are now officially in a bear market, having declined 20 percent from their (October) peak," said William O'Loughlin, investment analyst at Australia's Rivkin Securities.

Reuters technical commodity analyst Wang Tao said on Friday that "Brent oil may slide further into a range of $68.59-$69.69 per barrel."

That would be the first time Brent has fallen below $70 since April.

Analysts said the main downward price pressure came from rising supply, despite the U.S. sanctions against Iran that were imposed this week, as well as concerns over an economic slowdown.

"As OPEC exports continue to rise, inventories continue to build which is putting downward pressure on oil prices," analysts at Bernstein Energy said.

"A slowdown in the global economy remains the key downside risk to oil," Bernstein added.

The decline in prices over the past weeks follows a rally between August and October when crude rose ahead of the re-introduction of sanctions against Iran's oil exports on Nov. 5.

The sanctions, however, are unlikely to cut as much oil out of the market as initially expected as Washington has granted exemptions to Iran's biggest buyers which will allow them to continue buying limited amounts of crude for at least another six months.

China National Petroleum Corp (CNPC) said on Friday it was continuing to take oil from Iranian oilfields in which it has ownership stakes.

"Our main cooperation with Iran is upstream investment. Lifting equity oil is recouping our investment there," Hou Qijun, deputy general manager for CNPC, said on the sidelines of an industry event in Shanghai.

Bernstein Energy expects "Iranian exports will average 1.4-1.5 million barrels per day (bpd)" during the exemption period," down from a peak of almost 3 million bpd in mid-2018.
