Who decides what you pay at pump?

Oil companies don’t set the prices — prices are based on trading of futures contracts.

Consider the game of chicken that plays out every day across Pennsylvania State Highway 441. In Marietta, where the road hugs the Susquehanna River, a Rutter’s Farm Store gas station stands on one side, a Sheetz gas station on the other.

Kelly Bosley, who manages Rutter’s, doesn’t even have to look across the highway to know when Sheetz changes its price for a gallon of gas. When Sheetz raises prices, her own pumps are busy. When Sheetz lowers prices, she has not a car in sight.

She calls Rutter’s headquarters to report the competition’s new price and wait for instructions.

“I call a lot of times and say, ‘They went down, hurry up! Hurry up! Call me! Call me!’ Or it could be where theirs goes up, and I’ll say, ‘Take your time! You know, I like being busy.’ But I have no control over that.”

You think you feel helpless at the pump?

Bosley makes a living selling gas — and even she has little control over what it costs.

So how exactly are gas prices set? What determines the hair-pulling figure you see displayed in large electronic or plastic numbers?

It all starts with oil.

The biggest factor in the skyrocketing price of gasoline is the historic ascent of crude oil, which has surged from $45 per barrel in 2004 to more than $135 this past week.

In the first quarter of this year, based on a retail price of gas that now seems like a steal — $3.11 a gallon — crude oil accounted for all but about a dollar, or 70 percent, of the cost, according to the federal government.

The rest is a complex mix of factors, from the cost of turning oil into gas to taxes to marketing costs to, sometimes, nothing more than the competitive whims of your local gas station owner.

Not that understanding the breakdown makes it any less cringe-inducing to fill ’er up.

The knee-jerk villains in all of this are the oil companies, fat with multibillion-dollar profits, frequent targets of populist anger. But wait: The oil companies don’t set the price of oil or the cost of a gallon of gas.

Prices are a function of the open market, the result of futures contracts being traded on the New York Mercantile Exchange, or Nymex, and other exchanges around the world.

Buying the current July crude oil futures contract means you’re buying oil that will be delivered by the end of July. But most investors who trade futures have no intention of ever accepting the underlying oil: Like stock investors who frequently buy and sell their holdings, they’re simply betting that prices will rise or fall.

Of late, on the Nymex, oil futures have been rising.

Why? Blame the falling dollar. Oil is priced in U.S. dollars, and the weaker the dollar gets, the more attractive dollar-denominated oil contracts are to foreign investors — or any investor looking for a safe haven in the turbulent stock market.

The rush of buyers keeps pushing oil futures to a series of new records, and the rest of the energy complex, including gasoline futures, has followed. That pushes up the price of gas that goes into your tank.

There is some evidence Americans are buying less gas as the price marches higher, and common sense suggests they would cut back even more if gas rose to $4.50 or $5 a gallon.

Lower demand should mean lower prices — but it takes time for that to happen, given the enormous scale of refining operations that produce gasoline.

“Once demand begins to slow, that needs to translate into inventories, then you get some price weakening,” said Jim Ritterbusch, president of energy consultancy Ritterbusch and Associates in Galena, Ill. “But it takes a while.”

Oil and gasoline prices often move in the same direction, but they aren’t linked directly. In fact, while oil prices have more than doubled in the past year, gasoline is only up about 19 percent during the same time.

Oil prices often fluctuate with production decisions from the Organization of Petroleum Exporting Countries, which supplies about 40 percent of the world’s crude, or when conflict in the Middle East or Nigeria threatens supplies.

And the rise has only grown more dramatic. Oil sprinted higher this past week, rising more than $4 a barrel on Wednesday alone and past $135 on Thursday.

As for gasoline prices: They’re closely tied to demand from U.S. drivers and how efficiently refineries are operating. Falling production or inventories often send prices skyrocketing.

Those prices can vary greatly depending on the region.

The Gulf Coast is the source of about half the gasoline produced in the United States, and areas farthest from there tend to have higher prices because of the cost of shipping gas via pipeline and tanker truck all over the country.

Add higher taxes in places like California and New York that push the price higher.

Oil companies insist their earnings, measured against revenue, are in line with other industries. On top of that, rising oil prices have sharply cut profit margins for refining, and that hits the major oil companies — which both pump oil and refine it for use as gasoline.

A giant like Exxon Mobil can handle the blow. Its refining and marketing profits for the first quarter were down 39 percent from a year ago, but Exxon still banked a nearly $11 billion profit because of the hefty prices earned on crude it pumped out of the ground.

Smaller refiners aren’t so fortunate. Sunoco Inc.’s refining and supply business lost $123 million in the first quarter, hurt by lower margins. Tesoro Corp. lost $82 million for the same period.

In any case, huge profits at big oil companies like Exxon Mobil and Chevron aren’t because of high prices at the pump. Their massive profits are tied to their exploration and production arms, which are benefiting from record crude prices.

What happens when that gasoline makes its way to your neighborhood gas station?

Major oil companies own fewer than 5 percent of gas stations. Most are owned by small retailers — and many of them say they’re struggling these days to turn a profit on gas. That’s because wholesale gasoline prices have risen sharply in recent months — again, blame it on crude — but station owners have been unable to raise pump prices fast enough to keep pace.

And you can’t keep jacking up the price when drivers are buying less.

Gas station owners face a balancing act: They must try to maintain a price that allows them to afford the next shipment of gasoline but not give the competition an edge.

Stations pay tens of thousands of dollars for each gas shipment before they see a cent in the register. Eventually, many make only a few cents on a gallon of gasoline, a margin that can disappear altogether when credit card fees are added in.
