Hawaii has moved to limit wholesale gas prices, beginning next week, as consumers suffer high fuel costs. Traders drove the price of oil to $68 a barrel on some markets Thursday before levels eased back.

Hawaii, which has all of its oil shipped in, has some of the highest gas prices in the nation -- prices for regular unleaded hover at $3.10. The recent move is the first such effort in the United States since the oil shocks of the 1970s. But analysts say Hawaii's strategy may actually lead to higher prices.
