Fuel supplies in Mexico - something we need to keep an eye on? Two Killer Refinery Fires No Help as Pemex Seeks New Partners https://www.bloomberg.com/news/articles/2017-06-15/two-killer-ref...
It's not just Mexico. There are refinery fires all over the world including the U.S. Japan and Asian countries are supporting the countries that are having distribution and production problems. It's not uncommon in the oil industry. Distillates are in big demand right now. There is a map that shows the current refinery fires around the world, I think it is a Bloomberg website that has it.
It's not just "poor ole Mexico", it's part of the industry.
