The current external balance (B12) measure the surplus (if it is negative) or the deficit (if it is positive) of the total economy on its current transactions (trade in goods and services, primary incomes, current transfers) with the rest of the world. The current external balance thus shows how far residents call on saving by non-residents.
The current external balance is the balancing item in the external account of primary income and current transfers. It is equal to the external balance of goods and services plus the flows of income coming from the rest of the world
plus the sum of all resources from the rest of the world minus the sum of all uses going to the rest of the world, except capital transfers.
