VIENNA (AP) -- With Saudi Arabia declaring a "critical day" for OPEC, oil ministers of the cartel moved closer Wednesday to end infighting and reach an agreement to cut output for the first time in eight years.
The price of oil rallied as chances grew that the 14-nation group will agree on individual quotas for its members _ the international benchmark for crude oil soared $3.22 to $49.60 a barrel.
An OPEC decision to cut production could have an impact on consumers, as oil price increases feed into the cost of car fuel, heating and electricity.
An agreement appeared distant as late as the eve of the cartel's meeting due to a rivalry between Saudi Arabia, OPEC's top producer, and Iran, whose struggle for dominance in the Mideast is also playing out in the Organization of the Petroleum Exporting Countries.
The Saudis have been hesitant to shoulder the lion's share of a cut, while Iran has resisted reducing its own production. It argues it has yet to recover its output levels hit by years of sanctions.
But as ministers headed into their closed decision-making session, comments from both sides suggested a compromise was near.
"We have agreed to a waiver from a cut to Iran in recognition of the impact of the sanctions on their economy and their industry," said Khalid Al-Falih, the Saudi oil minister.
Iran's oil minister, Bijan Zanganeh, confirmed that "for Iran, no reduction, no freeze."
OPEC has in September laid out the contours of a cutback the ministers needed to sign off on Wednesday. That agreement aims to pare up to 1.2 million barrels a day off total OPEC production, which is now over 33 million barrels a day.
If implemented, it would send a signal that the cartel, which accounts for about a third of the world crude output, is once again focused on regulating supplies and prices after years of inaction that dented its image as the arbiter of the market.
Any lasting effect on oil prices is unclear, even if cuts are agreed on. Russia, a major non-OPEC oil producer also must join in, and with the world economy feeble and oversupplied with oil, a bounce may be only temporary.
Still, even a symbolic sign that OPEC is back in the business of regulating the market would be significant, something Al-Falih alluded to as the meeting convened.
Al-Falih expressed hope that non-OPEC producers would "also contribute and reciprocate" with oil cuts or freezes of their own in case Wednesday's meeting was successful.
Iran's Zanganeh also suggested a deal was near, declaring "I'm optimistic." He also claimed that non-OPEC oil nations "already have agreed to cut after our decision."
"It seems that Russia is ready and sent very positive signal to us for contributing," he said.
Resolving the Iran-Saudi dispute is key to the success of the meeting
Once second only to Saudi Arabia in production within OPEC, Iran chafed for years under sanctions that crimped its oil sales while watching its rival increase its output. With sanctions lifted this year as a result of a nuclear agreement, Iran is looking to regain its market share within OPEC while pushing the Saudis to give up gains it says were made while Tehran was sanctioned.
A compromise agreement could see Tehran increasing output, but not to pre-sanctions level of around 4 million barrels a day, as the Iranians originally demanded.
Even a full OPEC cut will not restore crude prices to the levels over $100 that a barrel fetched in June of 2014, before increased output from the U.S. and other non-OPEC countries led to oversupply.
OPEC then opted to pump at high volumes instead of throttling production, in an attempt to maintain market share and drive U.S. shale oil and gas producers with higher operating costs, out of business.
Crude prices plunged as a result. In January, they fell below $30 a barrel for the first time in over a decade before rising to levels now that are still less than half of their mid-2014 peak
