The debt market is usually categorised into the short-term debt market (STDM) and long-term debt market (LTDM), and includes marketable and non-marketable debt. The money market is comprised of the STDM and the deposit market (which is overwhelmingly of short duration). The bond market is the marketable arm of the LTDM. Bonds are issued by governments (all levels), companies and special purpose vehicles, and there are many types and many risks to holding them. The bond market is an important asset class, yielding returns second to equities. The bottom end of the bond yield curve reflects money market rates (which reflect monetary policy) and its longer end reflects the shorter end, expectations in respect of the shorter end (which includes future inflation), as well as confidence.
