<p>Commodities are raw materials or primary products that are traded in standardized contracts. They are often used in the production of goods and services, and their prices can fluctuate significantly due to factors such as supply and demand, weather conditions, and geopolitical events.</p>

<h2>How It Works</h2>
<p>Commodities are typically traded on exchanges, with the most common being the New York Mercantile Exchange (NYSE Arca) and the Chicago Mercantile Exchange (CME Group). These exchanges offer standardized contracts, which specify the quantity, quality, and delivery location of the commodity. Traders can buy or sell these contracts to speculate on the price movement of the underlying commodity or to hedge against price fluctuations.</p>
<p>There are two main types of commodity markets: spot markets and futures markets. Spot markets involve the immediate delivery of the commodity, while futures markets allow traders to buy or sell a commodity at a predetermined price and date in the future.</p>

<h2>Why It Matters</h2>
<p>Commodities play a crucial role in the global economy as they are essential inputs in the production of many goods and services. Therefore, the price of commodities can have a significant impact on the cost of living and the profitability of businesses. For example, a sudden increase in the price of oil can lead to higher gasoline prices, which can affect consumer spending and business operations.</p>
<p>Commodities also provide opportunities for investors to diversify their portfolios and hedge against inflation. Historically, commodities have had a low correlation with other asset classes, such as stocks and bonds, which can help to reduce portfolio volatility. Additionally, commodities can provide a hedge against inflation, as their prices tend to rise along with the general price level.</p>
