Reference excerpt

Gold, alongside platinum and silver, is highly popular among precious metals as an investment. Investors generally buy gold as a way of diversifying risk, especially through the use of futures contracts and derivatives. The gold market is subject to speculation and volatility as are other markets.

Gold price

Gold has been used throughout history as money and has been a relative standard for currency equivalents specific to economic regions or countries, until recent times. Many European countries implemented gold standards in the latter part of the 19th century until these were temporarily suspended in the financial crises involving World War I. After World War II, the Bretton Woods system pegged the United States dollar to gold at a rate of US$35 per troy ounce. The system existed until the 1971 Nixon shock, when the US unilaterally suspended the direct convertibility of the United States dollar to gold and made the transition to a fiat currency system. The last major currency to be divorced from gold was the Swiss franc in 2000. Since 1919 the most common benchmark for the price of gold has been the London gold fixing, a twice-daily telephone meeting of representatives from five bullion-trading firms of the London bullion market. Furthermore, gold is traded continuously throughout the world based on the intra-day spot price, derived from over-the-counter gold-trading markets around the world (code "XAU"). The following table sets out the gold price versus various assets and key statistics at five-year intervals.

Influencing factors

Like most commodities, the price of gold is driven by supply and demand, including speculative demand. However, unlike most other commodities, saving and disposal play larger roles in affecting its price than its consumption. Most of the gold ever mined still exists in accessible form, such as bullion and mass-produced jewelry, with little value over its fine weight, hence it is nearly as liquid as bullion, and can come back onto the gold market. At the end of 2006, it was estimated that all the gold ever mined totaled 158,000 tonnes (156,000 long tons; 174,000 short tons). Given the huge quantity of gold stored above ground compared to the annual production, the price of gold is mainly affected by changes in sentiment, which affects market supply and demand equally, rather than on changes in annual production. According to the World Gold Council, annual mine production of gold over the last few years has been close to 2,500 tonnes. About 2,000 tonnes goes into jewelry, industrial and dental production, and around 500 tonnes goes to retail investors and exchange-traded gold funds.

Central banks Central banks and the International Monetary Fund play an important role in the gold price. At the end of 2004, central banks and official organizations held 19% of all above-ground gold as official gold reserves. The ten-year Washington Agreement on Gold (WAG), which dates from September 1999, limited gold sales by its members (Europe, United States, Japan, Australia, the Bank for International Settlements and the International Monetary Fund) to less than 400 tonnes a year. In 2009, this agreement was extended for five years, with a limit of 500 tonnes. European central banks, such as the Bank of England and the Swiss National Bank, have been key sellers of gold over this period. In 2014, the agreement was extended another five years at 400 tonnes per year. In 2019 the agreement was not extended again. Although central banks do not generally announce gold purchases in advance, some, such as Russia, have expressed interest in growing their gold reserves again as of late 2005. In early 2006, China, which only holds 1.3% of its reserves in gold, announced that it was looking for ways to improve the returns on its official reserves. Some bulls hope that this signals that China might reposition more of its holdings into gold, in line with other central banks. Chinese investors began pursuing investment in gold as an alternative to investment in the Euro after the beginning of the Eurozone crisis in 2011. China has since become the world's top gold consumer as of 2013. The price of gold can be influenced by a number of macroeconomic variables. Such variables include the price of oil, the use of quantitative easing, currency exchange rate movements and returns on equity markets.

Hedge against inflation Gold, similar to other precious metals such as platinum and silver, may be used as a hedge against inflation or currency devaluation.

Jewelry and industrial demand Jewelry consistently accounts for over two-thirds of annual gold demand. India is the largest consumer in volume terms, accounting for 27% of demand in 2009, followed by China and the USA. Industrial, dental and medical uses account for around 12% of gold demand. Gold has high thermal and electrical conductivity properties, along with a high resistance to corrosion and bacterial colonization. Jewelry and industrial demand have fluctuated over the past few years due to the steady expansion in emerging markets of middle classes aspiring to Western lifestyles, offset by the 2008 financial crisis.

War, invasion and national emergency When dollars were fully convertible into gold via the gold standard, both were regarded as money. However, many people preferred to carry around paper banknotes rather than the somewhat heavier and less divisible gold coins. If people feared their bank would fail, a bank run might result. This happened in the USA during the Great Depression of the 1930s, leading President Roosevelt to impose a national emergency and issue Executive Order 6102 outlawing the "hoarding" of gold by US citizens. There was only one prosecution under the order, and in that case the order was ruled invalid by federal judge John M. Woolsey, on the technical grounds that the order was signed by the President, not the Secretary of the Treasury as required. Gold prices surged to a near two-month high in June 2025, driven by heightened geopolitical tensions between Israel and Iran, prompting investors to seek refuge in safe-haven assets like gold and platinum.

Worked examples

Example 1 — a first encounter with Gold as an investment

Start with the simplest possible case. Write down what Gold as an investment claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Gold as an investment before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Gold as an investment ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Gold as an investment

In research
Gold as an investment appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Gold as an investment in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Gold as an investment is common in secondary-school and first-year university syllabi. It links to neighbouring topics Commodities used as an investment, Currencies with ISO 4217 code, Gold in China, so understanding it makes those chapters shorter.
In everyday life
Look for Gold as an investment outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
