Cornering the Market Illegally

Cornering the market is illegal in most cases. If an investor controls the supply of security in the market to influence its price, it impacts traders’ sentiments—and, therefore, is illegal.

Moreover, the Securities and Exchange Commission (SEC) monitors illegal trading practices in the security exchange, foreign exchange, and bonds markets. At the same time, Commodity Futures Trading Commission (CFTC) monitors the possible cornering of commodity markets.

Markets are supposed to be fair—providing equal opportunities for businesses to compete and grow. However, practices like cornering violate the fundamental values of free trade. By cornering, individual investors block the supply of securities or commodities for individual gains.

Hoarding is the most common trading malpractice. The hoarder purchases security or commodity in bulk quantities—acquires a major stake in it. Consequentially, the market faces an artificial scarcity—the commodity price increases rapidly.


Let us look at some examples to understand how one entity corners its competition.

Example #1

Hamanaka’s unfair copper trading practice went on for ten long years—the metal price fell by one-third—the copper company lost $1.8 billion. For his notoriety, Hamanaka was later nicknamed “Mr. Copper.”
