Cornering the market,
Definition of Cornering the market:
Situation where an individual, firm, or cartel controls the supply of a commodity and dictates its price. Because cornering is often ruthless in its anti-social behavior, governments enact anti-monopoly or anti-trust laws to prevent its occurrence. Attempts to corner a market, however, do not usually last long because high prices encourage people to unearth the untapped supplies and create substitutes which break the corner.
