Who's speculating on oil? Maybe you

All those speculators getting the blame for driving up the price of oil these days, just who are they? For part of the answer, look in the mirror.

The retirement savings of workers across the country, entrusted to pension fund managers, are being plowed into one of the few investments that has delivered phenomenal returns in recent years.

For decades, futures contracts were mostly traded by commodity producers and the people who used the actual products, such as crude oil, corn and soybeans.

Agreeing to a price today for a commodity to be delivered in, say, two months is a way to smooth price fluctuations for those supplies.

But large investors have increasingly used them as protection against the falling dollar. That includes pension funds, along with investment banks, mutual funds and private hedge funds.

Research firm Ennis Knupp and Associates says $139 billion had been funneled into energy commodites, primarily crude oil, by the end of March – and it estimates more than half of that is from retirement money.

The investments have paid off. The Standard & Poor's GSCI index, which tracks a basket of commodities, is up 19 percent in the past five years, compared with just 9 percent for the S&P 500 stock index.

The risk is that if the remarkable run in oil and other futures markets reverses course, billions of dollars of retirement benefits could be wiped out.

“A pension fund is supposed to be investing money in secure, stable investments for the benefit of the people whose money they are investing,” said Dan Lippe, an energy analyst at Houston-based Petral Consulting Inc. “When we hit that wall and things start falling, they will fall very fast.”

The retirement system for public employees in California, the largest in the nation, has $1.3 billion invested in commodities. Most of it tracks the S&P commodity index.

That's still just one-half of 1 percent of the fund's total $240 billion in assets, said Michael Schlachter, who advises the California pension fund. He said a collapse in oil or other commodity prices would have little effect on retirees.

Still, a growing chorus of experts is convinced retirement investments are enough to distort prices.

Billionaire George Soros, the airline industry and the International Monetary Fund are pressuring Congress to curb speculation by large investors. Speculators put money into commodity markets simply to make money on their investments, unlike commercial investors, who are buying or selling orders for physical goods.

Energy analysts say it's unclear what effect speculators have had on oil prices, which climbed briefly to a new record above $142 on Friday before falling back.

But Stupak and other lawmakers have already dashed off more than a dozen proposals to rein in commodity trading, including limiting how many contracts speculators can hold and closing loopholes that allow them to skirt regulations.

Sen. Joe Lieberman, I-Conn., proposed banning pension funds and other large investors from commodities altogether. He dropped the idea after vigorous opposition by an association of public and private pension funds.

Unlike the stock market, where there are a limited number of shares for each company, futures markets have no limits on contracts available.Critics say retirement funds that accumulate contracts are artificially driving up commodity prices. Experts told members of Congress this week that eliminating excessive speculation could drive oil prices down to about $65 a barrel, less than half the current price.
