Compulsory Oil Stock
The Compulsory Oil Stock Directive (CSO Directive, 2009/119/EC) requires Member States to hold stocks of crude oil and petroleum products equating to 90 days of average daily net imports.
These reserves are generally held by oil companies, including independent fuel suppliers, and national agencies. They are financed by the end consumer. Depending on the system in each country, these reserves are supervised by the responsible national authorities.
This comprehensive system of compulsory oil stocks is a major contribution to Europe’s security of supply.
