- A nation can run a current account deficit accompanied by a government sector surplus of equal proportion to GDP, while the private domestic sector is spending more than they are earning.
- A nation can run a current account deficit with a government sector surplus that is larger, while the private domestic sector is spending less than they are earning.
- None of the above are possible as they all defy the sectoral balances accounting identity.
