Oil prices have dropped, closing out the largest monthly decline in two years on supply worries after OPEC output reached a 2018 high in July, overshadowing reports that the US and China might reopen trade talks that could boost demand.
October Brent crude futures fell $US1.34 to settle at $US74.21 a barrel on Tuesday.
The September contract, which expires later on Tuesday, settled at $US74.25, while US crude futures fell $US1.37, or nearly 2 per cent, to settle at $US68.76.
Brent lost more than 6 per cent in July, while US crude futures slumped about 7 per cent, the biggest monthly decline for both benchmarks since July 2016.
Oil prices extended losses in post-settlement trade, with US crude at $US68.32 a barrel, after data from the American Petroleum Institute showed domestic crude inventories rose 5.6 million barrels last week.
