Crude oil — plain-language explainer
Definition
– Crude oil is a naturally occurring liquid composed mainly of hydrocarbons and the remains of ancient plants and animals. Over geological time, heat and pressure transformed organic matter buried under sediments into the fossil fuel we call crude oil.
– Nonrenewable resource: crude oil cannot be replenished on human time scales at the rate we use it.
– Petroleum is a broader term that refers to crude oil plus the refined products made from it (for example, gasoline, diesel, kerosene, asphalt and petrochemical feedstocks).
How crude oil is found and turned into useful products
– Extraction: Companies drill wells into rock formations where oil has accumulated. Oil is often found together with lighter natural gas (which tends to sit above the oil) and heavier saline water (which collects below).
– Refining: Refining separates crude oil into component streams by heating and distillation (heating the oil to different boiling points). Those streams are further processed and blended into market products such as gasoline, diesel, jet fuel, liquefied petroleum gases and petrochemical feedstock.
Why crude oil matters to the economy
– Oil is a major commodity: its price affects gasoline costs, transport and shipping expenses, and production costs across many industries.
– Supply and demand drive prices: when supply outpaces demand prices fall; when demand exceeds supply prices rise. Perceptions about supply and demand also move markets — for example, geopolitical events, changes in OPEC (Organization of the Petroleum Exporting Countries) policy, natural disasters in producing regions, or technological shifts such as fracking.
A short history of the global oil market (high-level)
– Industrial Revolution and 19th-century innovations created strong industrial demand for crude-derived fuels.
– In the late 20th century OPEC had outsized influence because its members controlled large reserves. In the early 21st century, technologies like hydraulic fracturing (fracking) expanded U.S. production and reduced some of that influence.
– Today major producers include the United States, Saudi Arabia and Russia.
Environmental and operational risks
– Oil extraction and transport pose ecological risks (for example, oil spills and ocean impacts).
– Burning fossil fuels contributes to greenhouse gas emissions and global warming, which is driving a long-term shift toward alternative energy in some sectors (electric vehicles, solar and wind).
Spot contracts vs. futures contracts — definitions and differences
– Spot contract: an agreement to buy or sell oil for immediate delivery at the current market price. In commodities markets, spot prices generally reflect what buyers pay for immediate physical delivery.
– Futures contract: an exchange-traded or OTC (over-the-counter) agreement to buy or sell oil at a specified price on a specified future date. The futures price represents what market participants are willing to pay now for delivery later; it is an expectation or contractual price, not a forecast that must be realized.
– Practical difference: spot prices reflect today’s market; futures prices reflect the market’s assessment of supply, demand, storage costs and other factors through the chosen delivery date. Logistics and storage constraints limit how much oil is actually traded for immediate delivery, so many market participants trade futures rather than take delivery.
What spot and futures prices can tell an investor
– Spot price gives a snapshot of current market conditions and immediate supply/demand balance.
– Futures prices reveal market expectations about future supply/demand, carrying costs (storage, insurance), and risk premia. But futures are not guarantees that the spot price will equal the futures price at delivery — the final spot price depends on actual conditions at that future date.
How individuals and institutions can get exposure to oil
– Direct physical ownership is rarely practical for retail investors because of storage and delivery logistics.
– Futures markets let traders take positions on future prices — commonly used by producers, refiners and speculators.
– Exchange-traded funds (ETFs) and exchange-traded notes (ETNs) can provide easier access for retail investors; some track futures prices, others track baskets of energy company stocks.
– Shares of oil producers (integrated oil companies or drillers) give exposure to the industry without needing to trade commodities contracts.
– Volum
me-based derivatives such as options and swaps also let market participants tailor exposure — for example, a refinery might buy options to cap its input costs while a hedge fund may use swaps to synthetically long or short oil without taking futures positions.
Other ways to gain exposure include:
– Contracts for difference (CFDs) offered by brokers in some jurisdictions, which mirror price moves without delivering physical oil.
– Master limited partnerships (MLPs) and royalty trusts that pay income derived from production or pipeline fees.
– Structured products and commodity-linked notes issued by banks (check counterparty and credit risk carefully).
– Commodity mutual funds and actively managed ETFs that combine futures, company equities, and other instruments to achieve desired exposure.
How crude oil is benchmarked and traded
– Benchmarks: Two primary global benchmarks are West Texas Intermediate (WTI) and Brent. Benchmarks provide reference prices for specific grades and delivery locations; many physical contracts are priced as a differential to a benchmark.
– Trading venues: Most standardized oil futures trade on regulated exchanges (e.g., NYMEX/CME for WTI, ICE for Brent). Over-the-counter (OTC) markets handle bespoke swaps and forward contracts between counterparties.
– Contract size and units: A standard NYMEX WTI futures contract represents 1,000 U.S. barrels. Prices are quoted in U.S. dollars per barrel. Always confirm contract specifications (tick size, margin, delivery months) before trading.
Worked examples (practical, numeric)
1) Futures profit/loss
– Scenario: You buy one WTI futures contract at $70.00 per barrel. Each contract = 1,000 barrels.
– If settlement price rises to $80.00, your unrealized gain = ($80.00 − $70.00) × 1,000 = $10,000 (before commissions and margin costs).
– If price falls to $65.00, your loss = ($65.00 − $70.00) × 1,000 = −$5,000.
2) Roll (contango) cost for an ETF that holds front-month futures
– Front-month futures = $70.00; next-month futures = $72.00. ETF must sell front-month at expiry and buy next at $72.00.
– Roll cost per barrel = $72.00 − $70.00 = $2.00. For an ETF equating to 1,000 barrels, that is $2,000 of negative roll for the rollover. Repeated rolls in a contango market erode returns (roll yield negative).
Key factors that move crude oil prices (concise)
1) Supply fundamentals — production levels (OPEC+ decisions, national output), spare capacity, and inventories.
2) Global demand — GDP growth, transport fuel consumption, seasonal demand patterns.
3) Geopolitical risk — conflicts, sanctions, and political instability can disrupt supply or raise risk premia.
4) Currency shifts — oil is commonly priced in U.S. dollars; a stronger dollar tends to pressure dollar-denominated commodities.
5) Market structure — futures curve shape (contango vs. backwardation), speculative positioning, and liquidity.
6) Technical and sentiment factors — positioning by large traders, options implied volatility, and risk appetite.
Risk checklist for retail traders (practical)
– Understand leverage and margin: futures amplify gains and losses; know maintenance margin and potential for margin calls.
– Know rollover and contango/backwardation effects if using futures-based ETFs.
– Check counterparty and credit risk for OTC products and structured notes.
– Consider tax treatment: commodities, futures, and equities are taxed differently in many jurisdictions. Consult a tax professional.
– Confirm regulatory protections: exchanges, brokerage segregation rules, and investor protections differ by country.
Brief primer on hedging with futures (step-by-step)
1) Define exposure: e.g., an airline expects to consume 10,000 barrels of jet fuel over the next 6 months.
2) Choose hedge instrument: decide between crude futures, heating oil/jets swaps, or options. Crude futures are liquid but imperfect if jet fuel is the end product.
3) Calculate hedge size: if one crude contract = 1,000 barrels, hedging 10,000 barrels implies 10 contracts (adjust for correlation, basis risk).
4) Execute hedge: enter short futures positions to lock in input price.
5) Monitor and adjust: as consumption forecast changes, roll or offset contracts; account for margin and collateral.
Common pitfalls
– Confusing spot and futures: futures reflect expected future prices plus carry costs; spot is the immediate delivery price.
– Ignoring storage and physical logistics: owning futures doesn’t simplify physical delivery unless you intend to take/fulfill delivery and meet exchange requirements.
– Overlooking basis risk: local physical price may diverge from benchmark futures due to transportation and quality differentials.

Quick practical checklist for retail traders considering crude-oil exposure
– Define your objective: speculation, hedging, or long-term commodity exposure. Set a time horizon and risk tolerance.
– Choose an instrument that fits your objective: physical oil (rare), futures contracts, commodity ETFs/ETNs, oil-company stocks, or options. Each has different cost, liquidity, and tax treatment.
– Read contract specs and fund docs: if using futures, confirm contract size, tick value, quote convention, delivery months, and margin rules; if using an ETF, inspect holdings and roll policy. (See CME and fund prospectus.)
– Quantify costs: commissions, bid-ask spread, management fees, financing or margin interest, and roll costs (cost to replace expiring futures with later months).
– Understand non-price risks: storage/logistics limits, counterparty risk (for OTC products), basis risk (local physical price vs. benchmark), and regulatory or geopolitical shocks.
– Plan exit and risk controls: position limits in dollars or contracts, stop-loss rules, and maximum portfolio allocation to oil exposure.
– Tax check: determine how gains are taxed (e.g., U.S. exchange-traded futures often fall under IRS Section 1256 — 60/40 tax treatment). Consult a tax adviser.
Worked numeric example — one CME WTI futures contract (illustrative)
Assumptions:
– Contract size = 1,000 barrels (CME WTI, symbol CL).
– Entry price = $70.00 per barrel.
– Exit price = $75.00 per barrel.
– Ignore transaction costs and margin interest for simplicity.
Step 1 — Compute gross profit:
– Price move = $75.00 − $70.00 = $5.00 per barrel.
– Profit = $5.00 × 1,000 barrels = $5,000.
Step 2 — Translate to percent with assumed account exposure:
– If initial margin required = $5,000, and account equity = $20,000, the trade used 25% of account equity as margin. A $5,000 gain would be +25% on the $20,000 account (ignoring maintenance margin changes).
Notes and caveats for the example
– Margin requirements change with volatility and broker; you can lose more than initial margin if price gaps.
– Roll costs: if you hold exposure via a near-month futures and roll to a later month, the forward curve’s shape (contango or backwardation) creates a roll cost or benefit.
– ETFs that use futures (e.g., many oil ETFs) embed roll mechanics and management fees that materially change returns versus spot oil.
Basic formulas and definitions
– Contract profit/loss = (Exit price − Entry price) × Contract size.
– Tick value = minimum price move × Contract size (for CL, $0.01 × 1,000 = $10 per tick).
– Basis = Local spot price − Benchmark futures price; basis risk is the potential change in this difference.
– Contango = later-dated futures trade at higher prices than near-dated futures; rolling in contango tends to be costly.
– Backwardation = later-dated futures trade at lower prices than near-dated futures; rolling in backwardation can add return.
Risk-management checklist (short)
– Position size limit (percent of portfolio).
– Predefined stop-loss or hedging overlay.
– Liquidity assessment: average daily volume and open interest.
– Stress-test scenario: simulate price moves and their P&L impact.
– Monitor news sources for supply/demand shocks.
