Gold is respected throughout the world for its value and rich history, which has been interwoven into cultures for thousands of years. Coins containing gold appeared around 800 B.C., and the first pure gold coins were struck during the rein of King Croesus of Lydia about 300 years later. Throughout the centuries, people have continued to hold gold for various reasons. Below are eight reasons to own gold today.

1. A History of Holding Its Value
Unlike paper currency, coins or other assets, gold has maintained its value throughout the ages. People see gold as a way to pass on and preserve their wealth from one generation to the next. (Read more in Understanding Supply-Side Economics.)

2. Weakness of the U.S. Dollar
Although the U.S. dollar is one of the world's most important reserve currencies, when the value of the dollar falls against other currencies as it did between 1998 and 2008, this often prompts people to flock to the security of gold, which raises gold prices. The price of gold nearly tripled between 1998 and 2008, reaching the $1,000-an-ounce milestone in early 2008. The decline in the U.S. dollar occurred for a number of reasons, including the country's large budget and trade deficits and a large increase in the money supply.

3. Inflation
Gold has historically been an excellent hedge against inflation, because its price tends to rise when the cost of living increases. Since World War II, the five years in which U.S. inflation was at its highest were 1946, 1974, 1975, 1979 and 1980 (as of 2008). During those five years, the average real return on the Dow Jones Industrial Average was -12.33%, compared to 130.4% for gold. (As Coping With Inflation Risk explains, inflation is less dramatic than a crash, but it can be more devastating to your portfolio.)

4. Deflation
Deflation, a period in which prices contract, business activity slows and the economy is burdened by excessive debt, has not been seen globally since the Great Depression of the 1930s. During that time, the relative purchasing power of gold soared while other prices dropped sharply. (Read more in What Caused The Great Depression?)

5. Geopolitical Uncertainty
Gold retains its value not only in times of financial uncertainty, but in times of geopolitical uncertainty. It is often called the "crisis commodity", because people flee to its relative safety when world tensions rise; during such times, it often outperforms other investments. For example, gold prices experienced some of their largest recent movements during periods of tension with Iran and Iraq in 2007 and 2008. Its price often rises the most when confidence in governments is low. (Read how to cut through the confusion and invest successfully in Investing During Uncertainty.)

6. Supply Constraints
Much of the supply of gold in the market since the 1990s has come from sales of gold bullion from the vaults of global central banks. This selling by global central banks slowed greatly in 2008.

At the same time, production of new gold from mines has been on the decline since 2000. According to BullionVault.com, annual gold-mining output fell from 2,573 metric tons in 2000 to 2,444 metric tons in 2007. It can take from five to 10 years to bring a new mine into production. As a general rule, reduction in the supply of gold increases gold prices. (For more insight, read Economics Basics.)

7. Increasing Demand
Increased wealth of emerging market economies has boosted demand for gold. In many of these countries, gold is intertwined into the culture. India is one of the largest gold-consuming nations in the world, and gold has many uses there, including jewelry. As such, the Indian wedding season in October is traditionally the time of the year that sees the highest global demand for gold. In China, where gold bars are a traditional form of saving, the demand for gold has also shown rapid growth.

Demand for gold has also grown among investors. Many are beginning to see commodities, particularly gold, as an investment class into which funds should be allocated. In fact, the largest gold ETF, StreetTracks Gold Trust (PSE:GLD), became one of the largest ETFs in the U.S. and one of the world's largest holders of gold bullion in 2008, only four years after its inception. (Read more about gold ETFs in The Gold Showdown: ETFs Versus Futures.)

8. Portfolio Diversification
The key to diversification is finding investments that are not closely correlated to one another; gold has historically had a negative correlation to stocks and other financial instruments. Recent history bears this out:

• The 1970s was great for gold, but terrible for stocks.
• The 1980s and 1990s were wonderful for stocks, but horrible for gold.
• As of 2008, this decade has been a good one for gold, and an unfavorable one for stocks.

Properly diversified investors combine gold with stocks and bonds in a portfolio to reduce the overall volatility and risk. (Read Introduction To Diversification to find out how diversifying a portfolio can enhance returns and reduce risk.)

Conclusion
Gold should be an important part of a diversified investment portfolio because its price increases in response to events that cause the value of paper investments, such as stocks and bonds, to decline. Although the price of gold can be volatile in the short term, gold has always maintained its value over the long term. Through the years, it has served as a hedge against inflation and the erosion of major currencies, and thus is an investment well worth considering.
