584. Other investment is a residual category that includes all financial transactions not considered direct investment, portfolio investment, or reserve assets. Like portfolio investment, other investment is primarily divided into investments that represent the financial assets and liabilities of an economy. Within these asset and liability classifications, other investment transactions are further divided by instrument and resident institutional sector. Five types of instruments are identified in the BOP standard components: (1) trade credits, (2) use of at Fund credit and loans from the Fund, (3) other loans, (4) currency and deposits, and (5) other assets and liabilities. Each type of instrument is discussed in more detail in subsequent paragraphs.
