ABSTRACT
The authors investigate interest-rate aspects of the transmission mecha-
nism of monetary policy instruments in Canada, focussing on the stability
of the relationships between some key interest rates and the instruments of
monetary policy. To determine what shifts may have occurred in recent
years, they describe movements in rate differentials, apply cointegration
tests and estimate error-correction models. Some changes in the short-run
behaviour of money market yields, prime lending rates and mortgage rates
between the 1980s and the 1990s are apparent. However, the basic links of
the interest-rate channel of transmission – from policy instruments through
short-term rates to short-term bond rates and administered rates – seem
essentially stable.

RÉSUMÉ
Dans la présente étude, les auteurs examinent le profil des taux d'intérêt en
tant que courroie de transmission de la politique monétaire au Canada. Ils
étudient en particulier la stabilité des relations entre certains taux d'intérêt
directeurs et les instruments de la politique monétaire. Afin de déterminer
si ces relations ont subi des changements ces dernières années, ils ana-
lysent les fluctuations des écarts de taux et procèdent à des tests de cointé-
gration et à des estimations de modèles de correction d'erreurs. Les
résultats obtenus permettent de constater certaines modifications dans le
comportement à court terme des taux de rendement du marché monétaire,
des taux de base des prêts bancaires et des taux hypothécaires au cours des
années 80 et 90. Toutefois, les liens fondamentaux des taux d'intérêt
comme courroie de transmission de la politique monétaire paraissent
essentiellement stables. Ces liens qui proviennent des instruments de poli-
tique monétaire se répercutent sur les taux des obligations à court terme et
sur les taux administrés par le truchement des taux d'intérêt à court terme.

1 INTRODUCTION
In this paper we discuss the influence of Bank of Canada instruments on
interest rates, focussing especially on the posted interest rates on loans and
deposits at financial institutions. These are administered rates, in the sense
that each institution itself decides what rate to post and does not change
the rate with high frequency.
We start by outlining the new system of policy implementation
designed for zero reserve requirements and describe how it worked during
a trying period in late 1992. The primary issue for the purposes of this
report is whether the new framework has delivered a satisfactory degree of
influence over money market interest rates. We go on to discuss the stabil-
ity of the links from money market rates to short-term bond yields, which
impinge directly on certain administered rates. We outline the relevant fea-
tures of the markets for several key administered-rate instruments: busi-
ness loans, savings deposits, and residential mortgages and retail long-
term deposits.
Data on yield differentials are used to give a general picture of some
of the key facts. Cointegration tests and error-correction models (ECMs)
are used to shed light on the dynamics of rate setting and to look at how
these may have changed since 1990.
This report contains little on the exchange rate, except to discuss
how it has affected the setting of short-term interest rates. However, the
exchange rate is a very important component of short-run monetary condi-
tions in Canada. A change in monetary conditions initiated by the central
bank may be reflected in a change in the external value of the currency as
well as in the level of short-term interest rates. One difficulty in consider-
ing the exchange rate in this context is that its response to a policy action
tends to be less predictable than that of short-term interest rates, and more
dependent on the state of expectations.
