WTI crude oil prices are holding just under $65 per barrel mark, awaiting clarity on ongoing tensions between US and Iran. Negotiations between the two nations are set to continue although reports state that US issued a warning to all American-flagged ships to avoid Iranian waters while transiting the Strait of Hormuz. Traders brace for the release of the American Petroleum Institute (API) weekly report, which will be released later on Tuesday. Currently, the counter is quoting at $64.09 per barrel, down 0.36% on the day.
