What If Oil Hits $200?

Push prices up fast enough, he said, and "it would be the urban-planning equivalent of an earthquake."

Consumers

With every penny hike in the price of gas costing American consumers about $1 billion a year, sharply higher pump prices would lead to "significant bankruptcies and store closings," said Scott Hoyt, director of consumer economics at Moody's Economy.com.

Consumer spending has held up surprisingly well in the face of skyrocketing pump prices -- bolstered in part, perhaps, by federal tax rebates. But the same day the government reported a 0.8% rise in May consumer spending, a research firm said consumer confidence had plunged to its lowest level since 1980 -- hinting at the catastrophic effect another big gas price surge could have on retailers and customers.

"The purchasing power of the American people would be kicked in the teeth so darned hard by $200-a-barrel oil that they won't have the ability to buy much of anything," said S. David Freeman, president of the L.A. Board of Harbor Commissioners and author of the 2007 book "Winning Our Energy Independence."

BIGresearch of Worthington, Ohio, said more than half of Californians in a recent survey said they were driving less because of high gas prices. Almost 42% said they had reduced vacation travel and 40% said they were dining out less.

If any retailers would benefit, it would be those on the Internet. In a recent survey by Harris Interactive, one-third of adults said high gas prices had made them more likely to shop online to avoid driving.

Restaurant operators such as Brinker International, which owns the Chili's and Romano's Macaroni Grill chains, are suffering and are likely to struggle even more as consumers look for ways to reduce spending. Fast-food chains wouldn't be immune, experts say, although they might fare better as families downscale their dining choices.

Vehicle sales, too, would probably continue to tank. Sales of new cars, sport utility vehicles and light trucks fell more than 18% in California in the first quarter compared with a year earlier. Although some consumers have been shopping for smaller, more fuel-efficient vehicles, many dealers are demanding premiums for gas-sipping hybrids, wiping out much of the financial advantage of buying one.

Nationwide, $200 oil and $7 gasoline would force Americans to take 10 million vehicles off the roads over the next four years, Jeff Rubin, chief economist at CIBC World Markets, wrote in a recent report.
