Till now , i have only heard independency money policy *( it measures the undependency of the central bank: structural independency and the independency to enforce its policy---it means how independent the central bank can use which instrument to regulate the momey market.)
normally, central bank can not be absolute independent with government.
From this mean, government has more play space to make its own policy, for example , to issue bonds to balance its budget deficit, etc. Many central banks play its role just as an agent of its government.
