Oil has fallen 18 percent since its July record as the rising dollar curbed the appeal of commodities as a hedge against inflation. Gasoline use has dropped for 13 straight weeks, MasterCard Inc reported July 22.
Crude oil for September delivery fell $3.98, or 3.2 percent, to $120.75 a barrel at 10:48 a.m. on the New York Mercantile Exchange. Oil, which surged a record $147.27 a barrel on July 11, fell to $120.42 today, the lowest since May 6.
Oil's decline ``seems to be a reversal of money flow,'' said Kyle Cooper, director of research at IAF Advisors in Houston. ``It seems to be more technical and money-flow related.''
The dollar strengthened 0.8 percent to $1.5609 against the euro today, from $1.5741 yesterday, limiting the appeal of commodities as an inflation hedge. The U.S. currency appreciated 0.7 percent to $108.17 yen, from 107.46 yesterday.
