The dollar traded between 3,613 and 3,687.50 during 2,149 transactions totaling 1,269 million. The session coincided with Colombia's first presidential round five days away.
Brent futures rose 1.98 to 98.12 per barrel, while WTI stood at 91.79. Monday's US strikes on Iranian targets increased market uncertainty.
