Balance of payments should be distinguished from balance of trade. Balance of trade refers to the export and import of visible items, i.e., material goods. It is the difference between the value of visible exports and imports.
Visible items are those items which are recorded in the customs returns; for example, material goods exported and imported. If the value of visible exports is greater than that of visible imports, the balance of trade is favourable.
If the value of visible imports is greater than that of visible exports the balance of trade is unfavourable; if the value of visible exports is equal to that of visible imports, the balance of trade is in equilibrium. Balance of trade is also known as merchandise account of exports and imports.
Balance of payments, on the other hand, is a more comprehensive concept because it covers (a) visible items (i.e., balance of trade or merchandise account) and (b) invisible items.
Invisible items are those items which are not recorded in the customs returns; for example, services (such as transpiration, banking, insurance, etc.), capital flows, purchase and sale of gold, etc.
Thus, balance of payments is a broader term than balance of trade; balance of payments includes both visible as well as invisible items, whereas balance of trade includes only visible items.
