NEW YORK (MarketWatch) -- Crude futures accelerated their decline Tuesday, as stocks on Wall Street opened lower and the Commodity Futures Trading Commission started hearings on the energy markets. Light sweet crude for September delivery dropped $1.17 to $67.20 a barrel in electronic trading on Globex. CFTC Chairman Gary Gensler said Tuesday the futures market regulator "must seriously consider setting strict position limits in the energy market."
