SAN FRANCISCO (MarketWatch) -- Crude-oil futures traded lower Monday as investors were concerned about the threat of a default in Greece and its impact on the global economy, and the dollar traded higher. Crude for March delivery CL2H -0.75% declined 70 cents, or 0.7%, to $97.13 a barrel on the New York Mercantile Exchange. Greece is seen as running out of time to work out a deal for a second bailout package as party leaders have resisted more austerity measures.
