FDI is not the part of Current account balance (CAB).
The current account is an important indicator about an economy's health. It is defined as the sum of the balance of trade (goods and services exports less imports), net income from abroad and net current transfers. A positive current account balance indicates that the nation is a net lender to the rest of the world, while a negative current account balance indicates that it is a net borrower from the rest of the world.
