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).
Thus, the bond market is the market
in which governments and the prime members of the corporate sector
are able to issue long-term bonds, and investors can invest in and
trade in these bonds. This description is adequate.
The usual description of the money
market, however, is not adequate 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 utilized 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 (the price of debt)
are determined in the entire market and not just in the marketable
securities market. The "entire" market includes not only
non-marketable debt but also the significant interbank market. It
is in this market that interest rates have their genesis. There
are two interbank markets, one where rates are set administratively
(by the central bank), and the other where banks compete amongst
one another for cash reserves (called Federal Funds in the US) in
order to not borrow from the central bank (at the repo - also called
discount - rate).
This interbank activity ensures that
the bank-to-bank interbank rate closely follows the repo rate. The
central bank (by ensuring that the banks are always indebted to
it) is thus able to ensure that the repo rate is at all times made
effective - which means that the central bank essentially "pinpoints"
the short end of the yield curve. This is significant in that the
central bank has a major influence on bank deposit rates (the majority
of which are short-term) and therefore (via the bank margin) on
bank lending rates (and generally on asset prices - which plays
a major role in consumer behaviour - the main driver of the economy).
The level of bank lending rates influences
the demand for credit, and growth in the latter is the main driver
of the growth rate in the money stock. This significant money creation
role of the banks is played out in the money market.
