This indicator is a part of Balance of Payments. Current account balance is the export of goods and services by business entities of the country minus import of goods and services plus net investment income plus balance of transfer payments (payments not related to the movement of capital, i. e. loans, purchases of securities, salaries, etc.) In other words, the balance of payments is the ratio between the amount of payments received from abroad, and the amount of payments moving abroad. The balance can be either positive or negative.
The indicator is similar to the English PSNCR. It has little impact on the market.
