The balance of trade is

The balance of trade is the difference between the value of a country's visible exports and visible imports over a specific period. Visible trade refers to the import and export of physical, tangible goods such as crude oil, machinery, textiles, and agricultural products.

The formula is:

\[ \text{Balance of Trade} = \text{Value of Visible Exports} - \text{Value of Visible Imports} \]

If exports exceed imports, the country has a favourable (surplus) balance of trade. If imports exceed exports, it has an unfavourable (deficit) balance of trade.

It is important to distinguish the balance of trade from the balance of payments. The balance of payments is a broader concept that includes both visible trade (goods) and invisible trade (services such as banking, insurance, tourism, and shipping), as well as capital transfers and financial flows. An option describing the relationship between both visible and invisible receipts refers to the balance of payments, not the balance of trade.

For examinations, remember: balance of trade covers goods only (visible items), while balance of payments covers goods, services, and capital movements.
