The New York Mercantile Exchange started in the 1800s. There were scattered markets for the goods in large cities. You can picture a city like New York City and agricultural products being brought in and sold in various parts of it. So some entrepreneurial businessmen decided that they needed a central exchange. So in 1872, it was founded as the Butter and Cheese Exchange. In 1880, it was changed to the Butter, Cheese, and Egg Exchange. And then finally in 1882, it was changed to its present name of the New York Mercantile Exchange.
Later products would include yellow globe onions, apples, potatoes, plywood, and platinum. Platinum is the only product which is still traded today on the New York Mercantile Exchange. So today, it trades crude oil, heating oil, gasoline, propane, natural gas, platinum, and palladium.
Futures contract
The definition given by the New York Mercantile Exchange is “...a legally binding obligation for the holder of the contract to buy or sell a particular commodity at a specific price and location at a specific date in the future.” The key word here is future. These are known as futures. We are buying and selling energy commodities at a future date and time. And again, this is a legally binding obligation. This is what makes exchanges a sound place to conduct business. If you fail to perform under a contract obligation with the New York Mercantile Exchange, there are both financial and legal ramifications.
