Some of the banks had moved into owning storage and other assets to help facilitate trading.

Now, employees of the bank scour the world for jet fuel for the airline. They charter barges, lease pipelines and schedule tanker trucks, delivering more than a billion gallons a year to United's hubs. They even send inspectors to make sure no one tampers with the stuff.
What's a white-shoe investment bank doing selling oil? The answer unfolds in Purchase, N.Y., where an army of its commodities traders sit before flickering screens on a vast, domed trading floor staffed 24 hours a day. At the former site of Texaco's headquarters, Morgan Stanley veterans Neal Shear and John Shapiro run one of the most profitable energy-trading operations in the world.
But they don't just trade futures, a common way of betting electronically on commodities that involves buying and selling contracts for future delivery. Morgan Stanley also handles real barrels of oil and generates actual megawatts of power.
The reason is twofold. Having access to barges and storage tanks and pipelines gives the bank additional options, to move or store commodities, that most energy traders don't pursue. And by having its finger on the pulse of the business, it hopes to get a more subtle feel for the market, a crucial asset to a trader.
"Being in the physical business tells us when markets are oversupplied or undersupplied," says Mr. Shapiro. "We're right there seeing terminals filling up and emptying. Or we're there saying 'I need 500,000 barrels' when someone else says 'I don't have it.' "

In electricity, trader Simon Greenshields oversaw Morgan Stanley's construction of power plants in Georgia, Alabama and Nevada in the 1990s. When utilities need extra power during peak demand, Morgan Stanley traders sell them some. Those tend to be times when prices are higher.

In the 1990s, he made a bold real-estate play along a grimy refinery row in coastal New Jersey near New York Harbor. The New York Mercantile Exchange, the country's main hub for trading oil futures, designates about two dozen sites there and in New York as places where exchange-traded oil can be delivered. Through leases, Mr. Refvik locked up a large chunk of the official storage space. He laid claim to tank farms -- clusters of giant metal storage drums. His team also leases a big storage terminal in New Haven, Conn.
Messrs. Shear and Shapiro worried, at first, that the expensive leases could be albatrosses. But the move has worked so well that traders elsewhere dubbed Mr. Refvik "King of New York Harbor," a nickname that also reflects his occasional tour of the waters with his yacht, Song of Norway. Meanwhile, Morgan Stanley also acquired large amounts of oil-storage capacity in other countries.
