Global commodity prices can impact various industries and investment options. Commodities include agricultural products, fuels, and metals that are traded on exchanges. Fluctuations in gold prices can affect jewelers and retailers that sell jewelry. Gold is also used in other industries like medical products and aerospace. When economic outlook is dim, demand for gold as a "safe haven" investment tends to increase. Lower commodity prices generally benefit consumers and users of commodities as production inputs in countries like the United States. However, commodity-exporting countries like Brazil that rely on exports of items like iron, soybeans, crude oil, and sugar are more negatively impacted by lower global commodity prices.
