Oil prices reversed course today after rising over 1% in the previous session, on a firmer dollar and as investors shrugged off jitters arising from supply cuts from Saudi Arabia and Russia.
Brent crude futures were down by 59 cents to $89.45 a barrel, while US West Texas Intermediate crude (WTI) futures traded at $86.21 a barrel, down 48 cents.
Against a basket of currencies, the dollar was at 104.69, not far off the six-month high of 104.90 touched overnight.
A stronger dollar can weigh on oil demand by making the fuel more expensive for holders of other currencies.
"The reason the market gave back half of the gains and is listless this morning, is because within the language of the joint announcement there is a caveat that these cuts will be reviewed on a monthly basis," said John Evans of oil broker PVM.
"This flexibility add-in allows for wiggle room, but the market smells a taper," he said, citing conditions like anti-inflation battles in the US and other countries, whether crude prices near $100 a barrel, or the effect on Saudi oil revenues.
Saudi Arabia and Russia yesterday extended their voluntary oil cuts to the end of the year, the former to the tune of 1 million barrels per day (bpd) and the latter by 300,000 bpd.
These are on top of the April cut agreed by several OPEC+ producers running to the end of 2024.
Both countries will review their decisions monthly to consider deepening cuts or raising output depending on market conditions.
However, analysts warned that price rises could meet with obstacles as demand may dip when US refineries enter their September-October maintenance period, while potentially higher supply from Iran, Venezuela and Libya could also weigh.
