Crude Oil Market Handbook

The irreplaceable role of the spot market

The crude oil spot market is where buyers and sellers agree to trade physical crude with "immediate" delivery — typically within 15–45 days depending on the grade and region. There is no centralized exchange for spot trading; it is an Over The Counter (OTC) market, occurring via phone, Bloomberg Terminal chats, and electronic trading platforms.

What makes spot so crucial: the Official Selling Prices (OSPs) of Saudi Aramco, ADNOC, KPC, and all major producers are calculated by taking a spot benchmark price plus/minus a differential. Therefore, spot is the source of all oil prices in the physical market.

Brent Complex — The Global Benchmark

Brent is the most widely used oil price benchmark in the world, pricing about 70–80% of international crude contracts. ICE However, "Brent" today is no longer just oil from the Brent field — it is a complex basket of crudes known as BFOET+WTI Midland.

The Brent pricing mechanism operates across four tightly linked layers:

Dated Brent (assessed daily by S&P Global Commodity Insights/Platts) is the price of physical cargo that has been assigned a specific delivery date, 10–25 days ahead. This is the "price anchor" that all physical contracts reference. S&P Global Platts

WTI — The US Benchmark and the Geographic Paradox

West Texas Intermediate (WTI) is a high-quality light sweet crude (API 40.8°, sulfur 0.24%) physically delivered at the Cushing, Oklahoma hub — 700 km away from the coast. This is the famous "geographic paradox": an international oil benchmark anchored to a landlocked domestic pipeline hub.

When Cushing bottlenecks (in April 2020, near-month WTI futures traded at an unprecedented negative -$37.63/bbl), the massive storage costs forced contract holders to pay buyers to take the oil, exposing the limitations of pegging a benchmark to an inland storage point.

Dubai/Oman — Pricing Eastern Hemisphere Oil

About 70% of Middle Eastern crude exports go to Asia, and the vast majority is priced against Dubai or the Dubai/Oman average. Dubai is a medium sour crude (API 30.4°, sulfur 2.13%) freely traded at the Fateh port in the UAE.

However, Dubai's production has fallen sharply over the decades, making its spot market increasingly illiquid. Platts (S&P Global) overcame this by using a system of swaps and spreads to determine the Dubai price rather than relying solely on direct physical spot trades. Argus Crude

Murban — ADNOC's Emerging Benchmark

In March 2021, ADNOC (Abu Dhabi) launched the Murban futures contract on the ICE Abu Dhabi (IFAD) exchange — a strategic move to create a dedicated Middle East-Asia benchmark competing with the traditional OSP system. Murban (API 39.6°, sulfur 0.73%, 1 mb/d output) boasts growing liquidity and is gradually being adopted in international contracts.

What is a Term Contract and how it works

A term contract is an agreement between a producer (often a National Oil Company — NOC) and a buyer (refinery, trading house) to purchase a set volume of oil over a period of 1 to 5 years. Every month, the buyer must perform a lifting — dispatching a vessel to the designated port to receive the committed oil volume within an allocated time window.

Under a typical NNPC (Nigerian National Petroleum Corporation) contract, the buyer has the right to lift the total agreed monthly volume with a ±5% tolerance. If the buyer underlifts, they may face financial penalties or lose priority for contract renewal. NNPC General Conditions 2011

OSP — Official Selling Price: The Heart of Sales Policy

The OSP is the price state oil companies publish monthly for each crude grade they export. The OSP is not an absolute price — it is a differential against a market benchmark, reflecting crude quality and regional market conditions.

Saudi Aramco announces its OSPs at the beginning of each month for the subsequent loading month. The OSP is segmented into 4 crude grades (Arab Super Light, Extra Light, Light, Medium, Heavy) and 4 geographic regions (Asia, NW Europe, Mediterranean, USA), generating 20 different OSPs each month.

Regional Pricing Formulas by Major Producers

Delivery Terms: FOB, CIF, and DES

Every crude contract must explicitly state the point of risk and title transfer. The three most common mechanisms in international crude trade:

Oil Tanker Classifications

The VLCC is the "backbone" of global crude trade — each ship carries ~2 million barrels of oil (about 2% of daily US demand). Operating costs for a VLCC range from $20,000–30,000/day, but during market stress periods, rates can spike to $150,000+/day. Maritime-Hub.com, Feb 2026

Worldscale — The Language of Freight Pricing

Worldscale is a standardized index system for tanker freight rates, managed by the Worldscale Association. WS 100 represents the "standard" rate calculated annually for each route, based on standard vessel operating costs.

When Worldscale rates spike (tight shipping market), the added transport cost bumps up the CIF price at the destination, making long-haul crudes more expensive. This is why high VLCC rates in Feb 2026 (WS163, TCE ~$151,000/day) due to Hormuz tensions drastically inflated the cost of importing Middle Eastern crude into Asia.

Strategic Straits and Routes

International Pipelines

• CPC (Caspian Pipeline Consortium): Kazakhstan → Novorossiysk, Russia. 1.5 mb/d. Origin of CPC Blend benchmark.
• BTC (Baku-Tbilisi-Ceyhan): Azerbaijan → Turkey via Georgia. 1.2 mb/d. A route bypassing Russia.
• ESPO (Eastern Siberia-Pacific Ocean): Russia → Kozmino, 600k b/d. The main artery for Russian crude to Asia.
• Sumed (Suez-Mediterranean): Egypt. Oil bypass for the Suez Canal. 2.8 mb/d capacity.
• Kirkuk-Ceyhan: Iraq → Turkey, 350k b/d (frequently disrupted by Iraqi internal conflicts).

Strategic Petroleum Reserve (SPR)

The US Strategic Petroleum Reserve (SPR) along the Gulf Coast is the world's largest emergency crude stockpile, currently holding around 350–370 million barrels after massive releases in 2022–2023 to temper prices. Furthermore, the IEA mandates that member countries maintain reserves equivalent to 90 days of net imports.

Private storage at Cushing (Oklahoma), ARA (Amsterdam-Rotterdam-Antwerp), and Okinawa (Japan) play crucial roles in balancing short-term supply and demand, heavily influencing spot and forward pricing.

Refinery Configurations

Refineries are not created equal. The ability to process heavy-sour crudes and yield valuable "white products" dictates which crude is most profitable for any given plant.

The Nelson Complexity Index measures a refinery's sophistication. A coking refinery is roughly 10 times more complex than a topping plant, meaning it can squeeze far more white products out of each barrel of cheaper, heavy-sour crude. This is why US Gulf Coast refiners (Nelson index ~12) can outbid simple Asian refineries for heavy Canadian or Venezuelan crudes. Springer Petroleum Science 2017

Netback — Measuring the True Value of Crude

Netback is a method of calculating the value of a crude barrel by working backward from product prices: take the expected revenue from refined products (gasoline, diesel, jet fuel, fuel oil...), subtract refining and transport costs, leaving the maximum price a refiner is willing to pay for that crude.

Crack Spread — The Thermometer of Refining Margins

The crack spread is the price difference between refined products and the raw crude oil input. It is a quick gauge of a refiner's profit margin and one of the most closely watched metrics in the oil market.

Crude Oil Assay — The "Blueprint" of Each Grade

A crude oil assay is a comprehensive technical document detailing the chemical and physical properties of a crude grade. It includes API gravity, sulfur content, heavy metals (vanadium, nickel), pour point, Reid Vapor Pressure (RVP), and most importantly, the distillation curve (yield vs boiling point).

Using the assay, refiners can precisely calculate the product yields for their specific refinery configuration, enabling them to calculate netbacks and establish maximum buying prices. Assays are the critical technical baseline in all new crude contract negotiations. IEA Refinery Margin Methodology 2022

Price Reporting Agencies — The True Power Holders

There is no centralized exchange for physical crude. Therefore, Price Reporting Agencies (PRAs) — organizations that collect trading data and publish benchmark assessments — wield extraordinary power. All major producer OSPs are pegged against PRA assessments.

The Platts MOC (Market on Close) process is the most critical mechanism: during the final 30 minutes of each trading day, Platts aggregates all bids, offers, and deals for BFOE to assess Dated Brent. Even if only a handful of physical deals execute, this price serves as the global anchor. S&P Global Platts · Flux.live
