- Genscape reports that crude stockpiles at the Cushing, Oklahoma delivery hub rose by 1.7 million barrels.
- Turkey's financial crisis and trade wars threaten economic growth in emerging markets.
- U.S. sanctions targeting Iranian oil sector loom over markets.
Oil prices recouped much of their losses on Monday after moving sharply lower as data suggested inventories at the U.S. crude delivery hub rose in the latest week, compounding worries that troubled emerging markets and trade tensions will dent the outlook for fuel demand.
U.S. light crude ended Monday's session down 43 cents $67.20 a barrel, after hitting a seven-week low at $65.71. Benchmark Brent crude oil were down 20 cents to $72.61 a barrel by 2:29 p.m. ET, after briefly dropping to a nearly four-month low at $71.04.
Prices extended losses after inventories at the Cushing, Oklahoma, delivery hub for WTI rose by about 1.7 million barrels in the week through Aug. 10, traders said, citing data from market intelligence firm Genscape.
Crude inventories at Cushing have been dwindling, in part due to an outage at an oil processing facility in Canada that has reduced the flow of crude into the hub. The Canadian Syncrude processing facility has begun ramping up light oil production and was expected to return to full production in September.
"It is possible that it is the Syncrude return that has added to barrels," said Bob Yawger, director of energy futures at Mizuho.
Turkey's financial crisis has raised the risk of contagion throughout emerging economies, dragging down South Africa's rand, Argentina and Mexico's pesos and the Russian rouble. It has also dented emerging market stocks while curbing growth and the outlook for oil demand.
That is compounding worries that a deepening trade war between the United States, China and the European Union will squeeze business activity in the world's biggest economies. Crude oil futures have struggled to find a footing since Wednesday, after they fell about 3 percent as a trade dispute between the United States and China escalated further and after Chinese import data showed a slowdown in energy demand.
Turkey is a relatively small oil consumer, accounting for less than 1 million barrels per day (bpd), or around 1 percent of global demand. However, contagion concerns are prompting risk-off sentiment, Jim Ritterbusch, president of Ritterbusch and Associates, said in a note.
"The energy complex is being increasingly jostled by fresh daily headlines that don't necessarily have much effect on current supply or demand on a short term basis but could dramatically affect oil balances when looking down the road just a few months," he said.
The Organization of the Petroleum Exporting Countries forecast lower demand for its crude next year as rivals pump more and said top oil exporter Saudi Arabia, eager to avoid a return of oversupply, had cut production.
In a monthly report, OPEC said the world will need 32.05 million bpd of crude from its 15 members in 2019, down 130,000 bpd from last month's forecast.
Hedge funds and other money managers reduced their bullish positions in U.S. crude futures and options in the week ending Aug. 7, data from the U.S. Commodity Futures Trading Commission showed on Friday.
Despite the cautious mood in oil markets, bullish sentiment found some support from expectations that U.S. sanctions against Iran would restrict Iranian crude exports, tightening global supply.
The United States has started implementing new sanctions against Iran, which from November will also target the country's petroleum sector.
"There are lots of variables in the oil market, the most important of which is Iran," said Tamas Varga, analyst at London brokerage PVM Oil Associates.
"If 1 million bpd or more of Iranian exports go AWOL, the current fragile supply-demand balance will be upended, potentially sending oil prices above the May peak."
