Oil prices rose more than one per cent, on Wednesday, as investors sought bargains following the previous day’s slump.

But the recovery was stunted by fears of a slow recovery in demand due to new pandemic lockdowns in Europe and a build in U.S. crude stocks.

Brent crude futures rose 69 cents, or 1.1 per cent, to $61.48 a barrel by 0733 GMT, after tumbling 5.9 per cent and hitting a low of $60.50 the previous day.

West Texas Intermediate (WTI) crude futures climbed 63 cents, or 1.1 per cent, to $58.39 a barrel, having lost 6.2 per cent and touched a low of $57.32 on Tuesday.

Both benchmarks touched their lowest levels since early February on Tuesday and have now fallen about 14 per cent from their recent highs earlier this month.

The front-month spread for both Brent and WTI slipped into a small contango, where front-month contracts are lower than the later months.

This is a sign that demand for prompt crude is declining.

“Investors adjusted positions from Tuesday’s sharp selloff,’’ said Kazuhiko Saito, chief analyst at commodities broker Fujitomi Co.

“But the market sentiment remained bearish due to growing concerns about demand recovery in the wake of new pandemic curbs in Europe,’’ he said.

Germany, Europe’s biggest oil consumer, extended its lockdown to April 18 as Chancellor Angela Merkel urged citizens to stay at home for five days over the Easter holiday.

Worries over the pace of the recovery from the pandemic were also heightened after a U.S. health agency said the AstraZeneca Plc vaccine developed with Oxford University may have included outdated information in its data.

“Past patterns, in general, has been for the markets to pare back on initial lockdown announcements but then to recover.

“However, there are more worries at the moment about a lagged rise in U.S. COVID-19 cases to follow in Europe’s footsteps due to Spring break festive proclivities,’’ Stephen Innes, chief global market strategist at Axi said in a note.

“So, there is still a chance there could be more pain to come,’’ he said.

Adding to the pressure, U.S. crude oil stocks jumped by 2.9 million barrels in the week to March 19, against analysts’ expectations in a Reuters’ poll for a decline of about 300,000 barrels, according to trading sources citing data from industry group the American Petroleum Institute.

But gasoline stocks fell by 3.7 million barrels, compared with expectations for a build of 1.2 million barrels.

Human rights sanctions on China imposed by the U.S., Europe and Britain, which prompted retaliatory sanctions from Beijing, also added to market concerns.

The weakness in oil this week seems to have validated the cautious view expressed by Saudi Arabia at the last OPEC meeting and increases the probability of yet another rollover of current production levels at next week’s meeting, Axi’s Innes said.
