Financial Instruments can be categorised according to whether they are securities, derivatives of other instruments (see derivative securities), or so called cash securities. If they are a derivative, they can be further categorised depending on whether they are traded as standard derivatives or traded over the counter (OTC).

Alternatively they can be categorised by 'asset class' depending on whether they are equity based (reflecting ownership of an asset) or debt based (reflecting a loan the investor has made to the owner of an asset).
