Minyak mentah mempunyai harga yang berubah-ubah tergantung dari beberapa hal seperti:
1. nilai tukar USD terhadad EURO
2. permintaan dan penawaran dari industri di seluruh dunia
3. persediaan di AS sebagai pengguna minyak terbesar dunia
4. produksi OPEC, suatu organisasi yang terdiri dari negara2 pengexport minyak
Di bawah ini adalah beberapa benchmark atau tolok ukur untuk minyak mentah dunia.
Crude oil benchmarks, also known as oil markers, were first introduced in the mid 1980s. There are three primary benchmarks, WTI, Brent Blend, and Dubai. Other well known blends include the Opec basket used by OPEC, Tapis Crude which is traded in Singapore, Bonny Light used in Nigeria and Mexico's Isthmus. The Energy Intelligence Group has published a handbook which identifies 161 different blends in total.[1]
Benchmarks are used because there are many different varieties and grades of crude oil.[2] Using benchmarks makes referencing types of oil easier for sellers and buyers.
West Texas Intermediate (WTI)
West Texas Intermediate is used primarily in the U.S. It is light (API gravity) and sweet (low-sulfur) thus making it ideal for producing products like low-sulfur gasoline and low-sulfur diesel. Brent is not as light or as sweet as WTI but it is still a high-grade crude. The OPEC basket is slightly heavier and more sour than Brent. As a result of these gravity and sulfur differences, WTI typically trades at a dollar or two premium to Brent and another dollar or two premium to the OPEC basket.[3]
Brent Blend
Brent Crude is used primarily in Europe and the OPEC market basket, used around the world. This benchmark is a mix of crude oil from 15 different oil fields in the North Sea.[1]
Dubai and Oman
Dubai Crude is also known as Fateh is produced in the Emirate of Dubai, part of the United Arab Emirates.[4] Dubai's only refinery, at Jebel Ali, takes condensates as feedstocks, and therefore all of Dubai's crude production is exported. For many years it was the only freely traded oil in the Middle East, but gradually a spot market has developed in Omani crude as well.
For many years, most of the oil producers in the Middle East have taken the monthly spot price average of Dubai and Oman as the benchmark for sales to the Far East (WTI and Brent futures prices are used for exports to the Atlantic Basin). In July 2007, a potential new mechanism has arisen in the form of the Dubai Mercantile Exchange, which offers futures contracts in Omani crude. Whether the DME will be successful, and whether Omani futures prices will be adopted by producers and buyers as a benchmark, remains to be seen.
Contracts
Because of its excellent liquidity and price transparency, the contract is used as a principal international pricing benchmark.
Crude oil is the world's most actively traded commodity, and the NYMEX Division light sweet crude oil futures contract is the world's most liquid form for crude oil trading, as well as the world's largest-volume futures contract trading on a physical commodity. Additional risk management and trading opportunities are offered through options on the futures contract; calendar spread options; crack spread options on the pricing differential of heating oil futures and crude oil futures and gasoline futures and crude oil futures; and average price options.
The contract trades in units of 1,000 barrels, and the delivery point is Cushing, Oklahoma, which is also accessible to the international spot markets via pipelines. The contract provides for delivery of several grades of domestic and internationally traded foreign crudes, and serves the diverse needs of the physical market.
Untuk lebih detailnya :
WTI :
West Texas Intermediate (WTI), also known as Texas Light Sweet, is a type of crude oil used as a benchmark in oil pricing and the underlyingcommodity of New York Mercantile Exchange's oil futures contracts.
This oil type is often referenced in North American news reports about oil prices, alongside North Sea Brent Crude. Other important oil markersinclude the Dubai Crude and the OPEC Reference Basket.
Historical price data for WTI can be found at a website maintained by Energy Information Administration, Department of Energy. It is listed as WTI, Cushing, Oklahoma [1].
Typical price difference per barrel is about $1 more than Brent, and $2 more than OPEC basket.
BRENT
Brent Crude is the biggest of the many major classifications of oil consisting of Brent Crude, Brent Sweet Light Crude, Oseberg, Ekofisk and Forties. Brent Crude is sourced from the North Sea. The Brent Crude oil marker is also known as Brent Blend, London Brent and Brent petroleum. It is used to price two thirds of the world's internationally traded crude oil supplies.
Typical price difference per barrel is between +/-3 USD/bbl compared to WTI and OPEC Basket. The different price spreads are based on physical variations in supply and demand (short term). The depletion of the North Sea oil fields is one explanation for the divergence in forward prices.Crude :
OPEC BASKET :
The OPEC Reference Basket (ORB), also referred to as the OPEC Basket is a weighted average of prices for petroleum blends produced by OPEC countries. It is used as an importantbenchmark for crude oil prices
On June 15, 2005 the OPEC basket was changed to reflect the characteristics of the oil produced by OPEC members. The Reference Basket currently consists of a weighted average of the following blends of oil:
▪ Saharan Blend (from Algeria)
▪ Minas (from Indonesia)
▪ Iran Heavy (from Islamic Republic of Iran)
▪ Basra Light (from Iraq)
▪ Kuwait Export (from Kuwait)
▪ Es Sider (from Libya)
▪ Qatar Marine (from Qatar)
▪ Arab Light (from Saudi Arabia)
▪ Murban (from UAE)
▪ BCF 17 (from Venezuela)
Prior to June 15, 2005, the OPEC Basket consisted of the following:
▪ Arab Light (from Saudi Arabia)
▪ Fateh (from Dubai)
▪ Minas (from Indonesia)
▪ Saharan Blend (from Algeria)
▪ Tia Juana Light (from Venezuela)
OPEC attempts to keep the price of the Opec Basket between upper and lower limits, by increasing and decreasing production. This makes the measure important for market analysts. The OPEC Basket, including a mix of light and heavy crudes, is heavier than both Brent crude oil, and West Texas Intermediate crude oil.
DUBAI CRUDE:
Dubai Crude is a light sour crude oil extracted from Dubai. Dubai Crude is used as a price benchmark or oil marker because it is one of only a few Persian Gulf crude oils available immediately. The other two main oil markers are Brent Crude and West Texas Intermediate.
Dubai Crude is generally used for pricing Persian Gulf crude oil exports to Asia. The Dubai benchmark is also known as Fateh is used in the United Arab Emirates.[1] Forward trade of Dubai Crude is limited to one or two months.
Dubai Crude is a light oil. It has a gravity of 31° API (specific gravity of 0.871) and a sulfur content of 2%/weight[2]
