Crude posted the biggest monthly loss since July 2016 as a slew of factors from threats of weaker demand to key OPEC producers boosting output weighed on the market.

Futures in New York lost 7.3 per cent in July as some of the largest producers, such as Saudi Arabia, are seen raising supply levels.

The drop was exacerbated Tuesday amid low-volume trading and a strengthening dollar. Meanwhile, U.S. President Donald Trump said he would be willing to meet Iranian President Hassan Rouhani with “no preconditions” following Trump’s decision to withdraw from a 2015 nuclear deal.

“It’s some of these concerns about oversupply with OPEC. There are also starting to be concerns about the slowdown or the plateauing in demand," said Ashley Petersen, lead oil analyst at Stratas Advisors in New York. Still, the low volume is indicative of “the summer doldrums. The prices are down, but the activity actually hasn’t been that high.”

The U.S. benchmark crude declined in July as trade tensions between the U.S. and China weighed heavily on the market and as production from Saudi Arabia and Russia surged. Output in the U.S. remained at record levels. Consultants JBC Energy estimated that Saudi Arabia raised production by 310,000 barrels a day to 10.8 million a day in July.

West Texas Intermediate crude for September delivery fell US$1.37 to settle at US$68.76 a barrel on the New York Mercantile Exchange. Total volume traded was about 35 per cent below the 100-day average.

The global benchmark traded at a US$5.49 premium to September WTI. The more active Brent October contract lost US$1.34 to close at US$74.21.

The Bloomberg Dollar Spot Index rose as much as 0.2 per cent.

“I would certainly meet with Iran if they wanted to meet,” Trump said Monday during a joint press conference at the White House with Italian Prime Minister Giuseppe Conte. “I don’t know if they’re ready. They’re having a hard time.”

Yet, the White House said the U.S. will end sanctions on Iran only if the Islamic Republic changes its behavior.
