What you will learn

• How gold was used as money and why many people still see it as a store of value
• What the term "store of value" means and where the idea has limits

Explanation

Gold has been used as money for thousands of years. It does not rust, it is rare, and it can be divided into small units. This made gold coins practical money in many societies.

In the 19th and 20th centuries many countries used a gold standard: a system in which a currency could be exchanged for a fixed amount of gold. After the Second World War, the Bretton Woods system linked the US dollar to gold, and other currencies to the dollar. In 1971 the United States stopped exchanging dollars for gold at a fixed price. Since then, major currencies have been fiat money: money whose value rests on trust in the issuing state and its central bank, not on a metal.

Today, central banks still hold gold in their reserves, and many private investors buy it. The common reason is the idea of a store of value: an asset that is expected to keep its purchasing power over long periods. Gold cannot be printed and is not anyone's debt, so some people see it as protection against crises.

The store-of-value idea is a belief about the long run, not a guarantee. The gold price can fall sharply and stay low for many years. Someone who buys at a high price may wait a very long time to get back to break-even.

What gold does NOT do

Gold produces no cash flow. A share can pay a dividend (a part of company profit paid to shareholders). A bond pays interest (a fee for lending money). A rented flat pays rent. A gold bar pays nothing; its owner only gains if the price rises. Physical gold can also cost money to store and insure.

This creates an opportunity cost: the return you give up by choosing one use of money instead of another. When interest on savings is high, the opportunity cost of holding gold is high too.

Finally, keep two activities apart. Investing in gold usually means holding it for years as part of a wider plan. Trading gold means trying to profit from price moves over hours, days or weeks, often with leverage. This course covers both, and they carry very different risks.

Worked example

Hypothetical example: Anna has €10,000. She compares two choices over 5 years.

Assumptions: a savings bond pays a fixed 3% simple interest per year; the gold price in euros is exactly the same after 5 years as at the start. We ignore taxes, dealer spreads and storage costs.

1. Bond interest per year: €10,000 × 3% = €300.
2. Bond interest over 5 years: €300 × 5 = €1,500. Value after 5 years: €10,000 + €1,500 = €11,500.
3. Gold value after 5 years: €10,000 (price unchanged, no income).
4. Opportunity cost of gold in this scenario: €11,500 − €10,000 = €1,500.

The gold price would have to rise by 15% (€1,500 ÷ €10,000) in 5 years just to match the bond. If storage and dealer costs were included, gold would need an even larger rise. This is not a forecast; it only shows how the missing income works.

Common mistake

Practice activity

On paper, list three assets you know (for example a savings account, a share, a flat). For each one, write down what income it can produce. Then write one sentence explaining why gold differs from all three.

Limitations: Real savings rates, share dividends and rents change over time and are not guaranteed either.

Key takeaways

• Gold was used as money for a long time; since 1971 major currencies are not linked to gold.
• "Store of value" is a long-term belief, not a promise of stable prices.
• Gold pays no interest, dividends or rent, so holding it has an opportunity cost.
• Investing in gold and trading the gold price are different activities with different risks.
