Oil dips on signs of ample supply despite OPEC cuts, Iran sanctions

Oil prices fell on Wednesday, weighed down by ample supplies despite ongoing output cuts by producer cartel OPEC and looming U.S. sanctions against major crude exporter Iran.

Brent crude futures were at $78.23 per barrel at 0445 GMT, down 20 cents, or 0.3 percent, from their last close.

U.S. West Texas Intermediate (WTI) crude futures were at $71.08 a barrel, down 23 cents, or 0.3 percent, from their last settlement.

Despite the dips, both financial oil benchmarks remained close to their November 2014 highs of $79.47 and $71.92 a barrel respectively, reached the previous day.

But there are signs in physical crude markets that may give pause to financial investors.

There are also signs that oil production will rise, especially at majors like ExxonMobil, Royal Dutch Shell , Chevron, BP and Total.

"Aggregate production - both actual and projected - is growing for the majors," S&P Global Ratings said in a report published on Tuesday.

Spot crude oil cargo prices are at their steepest discounts to futures prices in years as sellers are struggling to find buyers for West African, Russian and Kazakh cargoes, while pipeline bottlenecks trap supply in west Texas and Canada.

The bottleneck in North America likely contributed to a 4.9 million barrel rise in U.S. crude oil inventories, to 435.6 million barrels, that the private American Petroleum Institute reported on Tuesday.

"The API inventory data in the U.S. fits with ... a topping pattern – or at least a decent pause – for oil prices at the moment," said Greg McKenna, chief market strategist at futures brokerage AxiTrader.

Official U.S. government fuel storage data is due for release by the Energy Information Administration (EIA) later on Wednesday.

"We expect the EIA report to display bearish results amidst higher rig counts and production levels in the U.S.," said Singapore-based brokerage Phillip Futures.

Despite Wednesday's dips and some indicators implying the financial oil has overshot physical oil, overall crude market conditions have tightened since 2017 when the Organization of the Petroleum Exporting Countries (OPEC) started to withhold supplies to push up oil prices.

With renewed U.S. sanctions looming against OPEC-member Iran and oil demand strong, analysts said crude markets will likely remain tight for much of the year.

Stronger oil prices are also spilling into other markets.

"A rising oil price brings upside price risk to all commodities," Morgan Stanley said in a note to clients this week.
