Most of the world’s corn isn’t eaten by people; but instead it is eaten by things people eat. Primarily cows, hogs and chickens.
One of the quirks of the American-led global Order that has dominated the world since World War II is that countries that normally couldn’t be physically secure or economically successful on their own suddenly could. For many that meant steadily increasing standards of living. That meant they wanted more and better food. Most people define more and better food as animal protein.
But while the Order radically changed the geostrategic environment, it didn’t touch the physical environment. If your climate and soil prevented you from growing a lot of of food before, you probably still couldn’t no matter what the Americans did or did not do. What you could do is build up an animal herd, and import the fodder to fatten it up. And so that’s what was done. Pretty much everywhere.
Global transport has crashed. The Americans used to use about half the corn they produced specifically to produce ethanol, a biofuel they mix into their gasoline. Since Americans are not driving, their need for ethanol has crashed right along with their need for gasoline. The United States is both the world's largest producer and exporter of corn. American farmers are planting their crops right now, and so far they are planting just as much corn as before.
With US transport demand unlikely to recover this year, we’re looking at gross global corn oversupply with the expected downward pressure on corn prices. Globally, this is great. It implies little risk (at least on the supply side) to global meat production. Among major corn producers, in contrast, it suggests quite the glut. Corn farmers the world over – most notably in the United States, China, Argentina and Brazil – be warned.
