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...
This is the map from Bloomberg that I had referred to earlier. It's from January of this year. I was surprised by the number of refinery fires around the world not just in Mexico. I know very little about the industry but 130 or so years later it still seems to be out of control.
In Mexico, apart from refinery problems are explosions and fires from clandestine pumping of gasoline from the pipelines which is sold on the black market in Mexico the U.S. and I am sure other nearby countries.
