Doha: Oil prices held their upward trajectory on Wednesday, driven by ongoing concerns over supplies due to a winter storm that disrupted US crude production and exports, along with a weakening dollar. Brent crude futures rose 23 cents, or 0.3 percent, to $67.80 a barrel, while US West Texas Intermediate crude climbed 32 cents, or 0.5 percent, to $62.71 a barrel, following a nearly 3 percent gain for both benchmarks in Tuesday's trading as the dollar neared its lowest levels in four years against a basket of major currencies.

According to Qatar News Agency, analysts and traders noted US production declines of up to 2 million barrels a day, or about 15 percent, early in the week, and pointed to signs that OPEC+, the alliance of the Organization of the Petroleum Exporting Countries, Russia and other allies, may keep planned production increases on hold for March.
