Money market instruments are the least talked about financial
asset because they are primarily used by the Treasury
operations of Central and international banks trading in an
exclusive, highly sophisticated market.
They are investments with a lifespan of 1 year or less, which
can be liquidated (sold for cash) at very short notice -
usually within a day. It is the liquidity which makes the
market useful to its key players - and it is the exclusive
nature of the marketplace and some basic product
characteristics which creates this high level of liquidity.
Market participants
Deep, liquid money markets exist particularly in USD,
EUR and GBP. Issuers are all top quality names of high
creditworthiness. Investors are mainly banks, shuffling
reserves around the world and speculating on the direction of
interest and exchange rates. Market participants all have
pre-arranged credit lines between each other to enable fast
trading. So there is constant trading of these extremely high
quality assets between market participants exposed to very
little counterparty default risk.
Product characteristics
Money market instruments are characterised by low
credit risk and high
liquidity. They sit at the bottom end of the risk/return
spectrum.
The short maturity date and high issuer quality creates an
investment proposition with little or no investment risk. The
cash value is safer in a money market instrument than in any
other asset class. There is virtually no risk of losing capital
(in a mature, sophisticated debt market). This means they
usually offer very low returns because investors are rewarded
primarily by the security value of the assets.
Within the asset class, there are differing returns
based on different levels of creditworthiness, from the
shortest dated
government bills to 1 year
commercial paper.
But they are all very secure relative to their alternatives in
longer-dated, more segmented
bond markets.
