Silver Thursday
Silver Thursday was an event that occurred in the United States silver commodity markets on Thursday, March 27, 1980, following the attempt by brothers Nelson Bunker Hunt, William Herbert Hunt and Lamar Hunt to corner the silver market. A subsequent steep fall in silver prices led to panic on commodity and futures exchanges.
Commodity market
A commodity market is a market that trades in the primary economic sector rather than manufactured products. The primary sector includes agricultural products, energy products, and metals. Soft commodities may be perishable and harvested, while hard commodities are usually mined, such as gold and oil. Futures contracts are the oldest way of investing in commodities. Commodity markets can include physical trading and derivatives trading using spot prices, forwards, futures, and options on futures. Farmers have used a simple form of derivative trading in the commodities market for centuries for price risk management.
