BREAKING DOWN 'Instrument'

1) Basically, any asset purchased by an investor can be considered a financial instrument. Antique furniture, wheat and corporate bonds are all equally considered investing instruments; they can all be bought and sold as things that hold and produce value. Instruments can be debt or equity, representing a share of liability (a future repayment of debt) or ownership.

2) Commonly, policymakers and central banks adjust economic instruments such as interest rates to achieve and maintain desired levels of other economic indicators such as inflation or unemployment rates.

3) Some examples of legal instruments include insurance contracts, debt covenants, purchase agreements or mortgages. These documents lay out the parties involved, triggering events and terms of the contract, communicating the intended purpose and scope.
