US markets closed with modest gains, which were mainly due to the rise in the oil sector, resulting from the sharp increase in crude price. The Department of Energy revealed that US oil reserves rose by 3.88 million barrels, a variation above 3.17 million estimated. After this increase, the American oil reserves reached the highest level since the decade of 30. However, for the 3rd consecutive week, gasoline stocks suffered a bending, this time of 4.52 million barrels (estimated – 1.49 million). To this information were added the statements of the Iraqi Minister of Petroleum who said OPEC members and other producers outside the cartel will meet in Moscow on 20 March. The other sectors did not experience significant changes, except the biotechnology companies which declined throughout the session, ending with a loss of 1.15%. Today, attention on Wall Street will focus on the reaction of European markets to the ECB meeting .
