Economic characteristics

Money is generally considered to have the following characteristics, which are summed up in a rhyme found in older economics textbooks and a primer: "Money is a matter of functions four, a medium, a measure, a standard, a store. That is, money functions as a exchange of medium, account of a unit and store of a value.

'Financial capital' is a more general and inclusive term for all liquid instruments, whether or not they are a uniformly recognized.
