Recent gains by West Texas Intermediate, or WTI, the U.S. benchmark oil grade traded on the Nymex, have erased the spread to the Brent contract traded in London from over $13 in April. Brent crude, the benchmark for many international types of oil, was down 63 cents to finish at $108.07 a barrel on the ICE Futures exchange.
Analysts say the U.S. benchmark appears overpriced at the current level, but caution against betting on a near-term drop.
Jim Ritterbusch, president of Ritterbusch and Associates, calls levels above $106 a "mispriced high" considering that U.S. demand growth is a modest 0.5 percent while U.S. crude production is up 15 percent year over year. But he says that's no guarantee the price will decline.
