Introduction and Background
The
debt market, made up of the money market and the bond market, is
an important element of the financial system. The bond market is
usually seen as the market for long-term marketable debt instruments
(ie bonds) and the money market as the market for short-term marketable
debt instruments, such as commercial paper (CP) and treasury bills
(TBs).
This usual description of the money
market is inadequate because this market is much more than the market
for short-term marketable debt instruments. The outstanding amount
of short-term marketable debt instruments is small compared with
the outstanding amount of short-term non-marketable debt, such as
mortgage advances, overdraft facilities utilised instalment sale
agreements and so on. These are also debt instruments (the assets
of banks) issued by the ultimate borrowers (as are CP and TBs).
Interest rates are discovered in the broader market and not only
in the marketable instruments market.
A critical element of the money market
is also the two interbank markets; in fact this is where very short-term
rates have their genesis. Monetary policy is played out in the interbank
markets (the repo rate is implemented here) and in the marketable
instrument money market (open market operations are implemented
here). Monetary policy is designed to curb the growth rate in bank
credit expansion and its counterpart, the money stock, and this
also plays out in the money market.
The definition of the bond market on
the other hand is adequate, but requires a little elucidation. We
need to distinguish between the long-term debt market and the bond
market. The former includes all long-term debt, marketable (such
as government and corporate bonds) and non-marketable (such as mortgage
finance), while the bond market includes only marketable long-term
debt. The banking system accommodates all forms of long-term debt
(if it is well-collateralised), but the other main investors (insurers,
retirement funds and bond unit trusts) only accommodate (buy) the
marketable debt of prime issuers.
The bond market can therefore be described
as the mechanism / conventions that exist for the issue of, investing
in, and the trading of marketable instruments that represent the
long-term undertakings (usually of a fixed capital nature) of the
issuers.
