Frequently Asked Questions
What is the difference between the Current Account and the Capital Account?
The Current Account records trade in goods and services, investment income, and unilateral transfers. The Capital Account records international transactions involving financial assets, such as foreign direct investment, portfolio investment, and loans.
What causes a depreciation of the domestic currency?
Depreciation is caused by an increase in the demand for foreign currency or a decrease in the supply of foreign currency, often driven by higher imports, capital outflow, or inflation differentials.
Why is the Balance of Payments always in balance theoretically?
The BoP is based on double-entry bookkeeping, meaning every international transaction creates a debit and a credit entry of equal value, so overall receipts must equal overall payments when including errors and omissions.
