Crude Oil rallied nearly 4% to finish above $77 on Tuesday, boosted by a drop in the Dollar against the EUR as concerns about Greece's debt faded. Crude oil for March delivery finished up $2.88, or 3.9%, at $77.01 a barrel at the New York Mercantile Exchange. Oil climbed the most in more than four months yesterday as the EUR rebounded from the lowest level against the greenback in 9 months. A weaker U.S. currency boosts the appeal of commodities as an alternative investment. Crude has also benefited from rising tensions between Iran and Western countries over its nuclear program. Iran is OPEC's second-largest Oil producer. Prices also gained after a better than expected result from the Empire State Manufacturing survey.
