Cuba has less than a month worth of oil at current levels of demand and domestic production after a recent shipment from Mexico was halted, according to a new report. Citing data company Kpler, the Financial Times noted that the country has oil to last 15 to 20 days unless deliveries resume. "They have a major crisis on their hands" Jorge Piñon, an oil expert at the University of Texas told the outlet. U.S. lawmakers involved in regional politics had celebrated a recent report noting that Pemex halted a shipment earlier this month. However, they have gone back to criticizing the country as talk of regime change in Cuba increases following the capture of Venezuela's authoritarian President Nicolas Maduro.
