Gas futures are a type of financial contract that allows buyers and sellers to lock in the price of natural gas at a future date. This can be useful for businesses that want to protect themselves from price fluctuations, or for investors who want to speculate on the future price of natural gas.
There are a number of different ways to buy gas futures, but the most common is through a futures exchange. Futures exchanges are regulated marketplaces where buyers and sellers can trade futures contracts. When you buy a gas futures contract, you are agreeing to buy a certain amount of natural gas at a certain price on a certain date. The price of the contract is based on the current spot price of natural gas, plus or minus a premium. The premium is determined by a number of factors, including the length of the contract, the volatility of the natural gas market, and the creditworthiness of the buyer and seller.
