Different Units for Financial Oil Trading
Different products get traded in different units. Very roughly:
|Product group||Trades in CCY/Unit||Unit Type|
|Crude||$ / Barrels||Volume|
|Clean [US]||cents / Gallons||Volume|
|GO / Diesel||$ / Ton||Weight|
|FO [US]||$ / Barrels||Volume|
|FO [Europe / Asia]||$ / Ton||Weight|
Trading Crack / Basis swaps and options
When trading cracks / basis spreads between different oil products it’s often required to trade them on a common unit (depending on market convention). This requires that on the deal that Endur can convert from the product unit to the deal unit. For this there are two types of conversion required.
Unit Conversion between Volumes: BBL / GALLONS
This is a standard conversion:
1 Barrel = 42 Gallons
Unit Conversion between Volume and Weight:
Density Adjustment on Index
Any conversion between a Volume and a Weight requires knowledge of the density of the product. The definition of density is = Mass / Volume.
- In Endur this density is recorded on the Index Definition under the Density Adjustment field.
- The Endur (price) Density Adjustment = 1 / Density .
Setting the MT<->BBL conversion factor to 1
|In the Admin Mgr Unit Conversion module, set the conversion|
MT <> BBL to = 1
Which will ensure Endur uses the pure Density Adjustment value (otherwise it will additionally adjust by whatever value is entered here)
Unit Conversion Calculation ( on deal )
Once the density adjustment is on the curve, Endur can convert from Volume <-> Weight in order to book a Crack / Basis spread deal where a common unit across two different Volume/Weight units is required.
Sometimes it’s the Price/Unit that needs converting and sometimes it’s the Unit. Both conversions are done as follows:
Endur obtains the Density Adjustment from the curve.

Example calculation of Density and Density Adjustment
The following is an example calculation of the density and density adjustment of Jet Fuel.
