Will Russia, Qatar, Venezuela, and Saudi Arabia finally have mercy on the global oil industry?

That was the question raised on Monday, when the four countries announced a tentative deal to freeze their oil output — pursuant to a few as yet unmet conditions, of course.

Up through mid-2014, the price of oil had been cruising along at about $110 per barrel. But problems were brewing: The slowdown in the global economy was cutting demand for oil in China and other developing markets. Meanwhile, the boom in North American shale oil production was driving up supply. And that's not the sort of thing companies can just flip off like a switch: The costs of paying off loans or of maintaining major projects like deepwater drilling can force companies to keep pumping to cover these expenses even when oil prices plunge.

Finally, the Organization of the Petroleum Exporting Countries (OPEC) — which includes Saudi Arabia, Qatar, and Venezuela, and keeps in dialogue with Russia — made an unusual decision. Instead of cutting production to bring supply more in line with demand, they decided to keep boosting production — the explicit point being to drive down the price and knock competitors out of business so they could corner more of the global oil market.

By the end of 2013 supply overtook demand and the global industry began building up big stockpiles of unused oil. Around mid-2014, the financial markets could no longer bridge the gap to sustain prices. The cost of a barrel of oil dropped like a rock, reducing itself by almost two-thirds. It's now bouncing around between $30 and $35 per barrel — the lowest it's been in a decade.

This brings us to the problems with the new deal proposed by Saudi Arabia & Co.

First off, the proposition is to freeze oil production at its January levels. They'd keep pumping, they just wouldn't increase the rate at which they're pumping. But industry experts weren't really expecting Russia, Qatar, and Venezuela to increase production much anyway, since they're already pumping about as fast as their infrastructures can manage.

As it stands, OPEC pumped a whopping 32.3 million barrels per day (mb/d) in January. Simply freezing at that rate isn't going to help much, as these December projections from the International Energy Agency (IEA) show:

The IEA actually assumed a slightly lower rate of OPEC output than what the international group pumped in January, and their projections still show supply (the green line) outpacing demand (the yellow line) at least through the end of 2016's third quarter. This means increases in oil stockpiles (the blue bars, measured on the right axis) will keep happening every quarter. But what's needed is for demand to overtake supply again, so that those blue bars can go negative again and the global industry can draw down the glut of oil stockpiles it's already built up.

"The market does not need a freeze. It needs a reduction," Michael Lynch, president of Strategic Energy and Economic Research in Massachusetts, told The New York Times. "They are not offering anything like that."

This isn't too surprising: Several OPEC nations, such as Saudi Arabia and Venezuela, are so thoroughly dependent on oil to fund their governments and power their economies that they can't really afford to stop pumping regardless of the price.

There are other wrinkles, too. The deal only holds "if other producers join this initiative," according to the Russian Energy Ministry. And neither Iran nor Iraq — both OPEC members — were among the initial four floating the idea.

Iraq is also already pumping about as fast as it can. And Iran is looking to ramp up: Its oil production was already slumping when sanctions were imposed on its exports in 2012. That drove Iranian production even lower, and it hasn't recovered since. Thanks to the nuclear deal, the sanctions were lifted last month, and Iran has made it clear they want to return to their pre-sanction rates of oil production. (IEA's projections assumed a ramp up in Iranian production as well.)

In short, even if the deal goes through, the main thing it might head off is an extra 0.73 mb/d from Iran. And that's nowhere close to what's needed to stabilize the price of oil. And the deal probably won't go through anyway, unless Saudi Arabia, Russia, Qatar, and Venezuela can convince Iran to swallow its pride.

At this point, the deal doesn't look like much more than Saudi Arabia & Co. trolling the global oil market.
