A market run or run on the market occurs when consumers increase purchasing of a particular product because they fear a shortage.
As a market run progresses, it generates its own momentum: as more people demand the item, the supply line becomes unable to keep up.
This causes a local shortage, which in turn encourages further hoarding.
Examples include a run on the gasoline market following hurricane Katrina in 2005, an ammunition shortage following President Obama's election in 2008,[1] and a run on toilet paper following a Johnny Carson joke on The Tonight Show in 1973.
