Intro
Commodities are the raw materials the world runs on — the gold in a central bank's vault, the oil in a tanker, the wheat in a silo, the copper in a power cable. They are also one of the oldest markets in the world, and one of the most misunderstood by new investors. This guide explains what commodities are, how their prices are set, and what actually moves them — with this week's real market numbers as the worked example.
What Counts as a Commodity?
A commodity is a basic good that is interchangeable with other goods of the same type: one barrel of Brent crude is the same as any other barrel of Brent crude, one ounce of gold the same as any other ounce. Commodities fall into four broad groups:
- Energy — crude oil (Brent, WTI), natural gas, gasoline, heating oil. The biggest commodity market by value traded.
- Metals — precious metals (gold, silver, platinum, palladium) and industrial metals (copper, aluminium, nickel, zinc).
- Agriculture — wheat, corn, soybeans, coffee, sugar, cotton.
- Livestock — live cattle, lean hogs.
Most investors meet commodities through futures contracts — agreements to buy or sell a set quantity at a set price on a future date — traded on exchanges like NYMEX and ICE. You can also buy them through ETFs, or hold physical metal. The spot price is what the commodity trades for right now; the futures price is what the market expects it to be worth later.
This Week's Numbers, Explained
Commodities have had a wild week, and it shows why beginners should watch the drivers, not just the price. Spot gold traded near $4,125 an ounce on Thursday, November 5 — up about 1.6% on the day — then slipped back below $4,100 on Friday morning, November 6, trading around $4,044 as rebounding oil revived inflation worries. Gold had touched an intraday high near $4,147 on Thursday, its highest since October 20. Silver traded near $52.58 an ounce, up 0.65%.
Oil told the opposite story in the same week. Brent crude settled 8.7% lower at $94.62 a barrel on Wednesday, November 4 — its lowest since early September — after hopes grew for a US–Iran de-escalation following the US midterm elections. Then it rebounded: January Brent futures climbed to around $99.58 on Friday morning, with US WTI crude near $91.38. Brent was still on course for a weekly decline of roughly 12%.
The lesson is in the contrast: gold and oil moved in opposite directions on the same news. De-escalation hopes pushed oil down (less risk to shipping and supply) and pushed gold up at first (a weaker dollar and lower Treasury yields), before Friday's oil rebound pulled gold back. Commodities do not move as one block — each has its own drivers, and the same headline can push two of them in opposite directions. We tracked the same moves in our gold and oil market update.
What Actually Moves Commodity Prices
- Supply and demand, in the real world. OPEC production decisions, a drought in a wheat region, a mine shutdown, a cold winter — physical supply and demand set the baseline. Oil's 8.7% Wednesday fall was a supply-risk story: less fear of disrupted Middle Eastern shipping.
- The US dollar. Most commodities are priced in dollars. When the dollar strengthens, commodities get more expensive for buyers in other currencies, which usually pushes prices down — and vice versa.
- Interest rates and real yields. Gold pays no interest, so when real yields rise, holding gold costs more in lost income, and gold usually falls. When yields fall, gold usually rises. This is why gold jumped on Thursday as Treasury yields declined.
- Geopolitics and risk sentiment. Wars, sanctions, shipping incidents and elections move oil and gold first. A reported tanker incident north of Qatar on November 5 helped oil rebound the next morning.
- The economic cycle. Industrial metals like copper track construction and manufacturing demand; when factories slow, copper usually falls first — which is why traders call it "Dr Copper" and treat it as an economic bellwether.
How Beginners Usually Get Exposure
Most beginners never touch a futures contract, and for good reason: futures use leverage, and a small price move can mean a large gain or a large loss. The common routes are:
- Commodity ETFs — funds that track gold, oil or a broad basket, bought like a stock through a broker.
- Mining and energy stocks — shares in gold miners or oil producers, which move with commodity prices but carry company risk too.
- Physical metal — gold and silver coins or bars, bought from a dealer and stored securely. No leverage, but storage and dealer spreads cost money.
Whichever route you choose, the same rules apply: never trade on margin until you understand it, never put money you cannot afford to lose into a single commodity, and remember that commodities can stay volatile for weeks — Brent lost roughly 12% in a single week while gold swung more than $100 an ounce in a day.
Gold vs Oil: The Classic Pair to Watch
Gold and oil are the two commodities beginners watch most, and they behave very differently. Gold is a safe haven and a store of value — investors buy it when they fear inflation, currency weakness or crisis. Oil is a growth and geopolitics barometer — its price tracks transport demand, OPEC supply and Middle East risk. When the economy booms, oil usually rises and gold can fall; when crisis hits, gold usually rises and oil can fall if demand collapses. Watching the pair together tells you more than watching either alone. For a deeper look at what drives oil specifically, see our guide to what moves oil prices.

FAQ
What is a commodity? A basic, interchangeable good — oil, gold, wheat, copper — traded in standardised units. One barrel of Brent crude is the same as any other barrel of Brent crude.
What is the difference between spot and futures prices? The spot price is what a commodity trades for right now. A futures price is the price agreed today for delivery on a future date, and it reflects what the market expects the price to be then.
Why did gold and oil move in opposite directions this week? De-escalation hopes cut oil's risk premium (Brent fell 8.7% on November 4) while a weaker dollar and lower yields lifted gold. When oil rebounded on Friday, gold pulled back below $4,100. Each commodity has its own drivers.
Is gold a good investment for beginners? Gold is a store of value and a hedge against inflation and currency weakness, but its price can swing sharply — more than $100 an ounce in a day this week. It pays no interest, so it competes with bonds and savings accounts.
How can a beginner invest in commodities without futures? Through commodity ETFs bought like stocks, through mining or energy shares, or by holding physical gold and silver. Futures use leverage and are not a beginner product.
