The politics of Donald Trump continue to affect us at the pump.

Oil prices are rising back up to last month's highs, ahead of this week's meeting of OPEC leaders in Vienna.

JIran and Venezuela are likely to veto the increase, to protest Donald Trump's tariffs.

JMI Wealth director Andrew Kelleher says told Mike Hosking Russia and Saudi Arabia want to increase production, but could have their hands tied.

"They can increase capacity, there's been talks of anything from 500,000 barrels a day through to 1.5 million barrels a day," he said.

"The waters are muddied of course by the US because they have sanctions against Iran and Venezuela - the Iranians, the Iraqis, the Venezuelans, they don't like that."
