Long-haul transport is what brings everything from areas of high supply to high demand, regardless of participant. For any product that is concentrated in terms of supply or demand, expect market collapse. Products particularly concentrated in terms of supply include oil, soy, lithium, and mid- and low-end microprocessors. Products particularly concentrated in terms of demand include liquefied natural gas, bauxite, high-speed train cars, and squid. Products facing a double squeeze include iron ore, helium, cocoa beans, and printer toner.
