If we study the figures of imports into the GCC Countries, we will see that imports from the Euro Area have stayed almost static at about 20-21% over the past five years. As an outsider to the Euro, the GCC Countries must have economic reasons to hold Euros, one of these reasons is to pay for the import bill.
In the case of GCC Countries the import bill from the Euro Area has not increased in percentage terms, which means that trade needs for the Euro within the GCC Countries did not grow, as a matter of fact it declined slightly from 21.84% of all imports in 2001 to 20.34% in 2005.
