Oil rallied for a second day after U.S. inflation rose less than expected and bad weather delayed initial efforts to restart the Keystone pipeline. There is still no official timeline for a restart of the key Canada-U.S. pipeline, which was closed after the spill of roughly 14,000 barrels of crude was discovered on Wednesday of last week in Washington County in Kansas. The U.S. Pipeline and Hazardous Materials Safety Administration said TC Energy is yet to submit a restart plan. The affected segment of the line cannot resume operation until regulators approve a restart plan in its entirety, according to a U.S. Department of Transportation document. WTI for January delivery advanced $2.22 to settle at $75.39 per barrel in New York. Brent for the February settlement gained $2.69 to settle at $80.68 per barrel.
