How come when you turn to any financial station they emphasize the price of oil and gold?

I don't understand why these are so important?How come when you turn to any financial station they emphasize the price of oil and gold?
Oil is like the blood of the world's economy. Whatever happens to the price of oil will invariably effect the entire economy. The price of Gold is useful because it's an indicator of how people feel about the economy. If the price of Gold is rising that means people are buying more and pushing the price up. This could indicate they are fearful of investing in the stock market or elsewhere. Gold is safe. If the price is falling then it could mean people are selling their gold and investing elsewhere.





Bottom line...oil and gold are indicators of where the economy is headed.
