aIntroduction
� Monetary Policy is the deliberate use of monetary instruments
(direct and indirect) at the disposal of monetary authorities such as
central bank in order to achieve macroeconomic stability
� Macroeconomic stability refers to achievement of internal and
external Balance
� Internal Balance here refers to:

aIntroduction…cont.
� For most central banks, the objective of price stability is given priority
over others in the conduct of monetary policy
� In some instances, however, the laws establishing the central bank
impose dual mandate of low inflation and high growth…necessitating
the formulation of monetary policy that attempt to strike a balance
between the two goals
Mandates of CBN

� Mandates of CBN
� The CBN Act. 2007, assigns the following mandates to CBN
� Ensure monetary and price stability
� Issue legal tender currency in Nigeria
� Maintain external reserves to safeguard the internationalvalue of the legal tender currency
� Promote sound financial system in Nigeria; and
� Act as banker and provide economic and financial advice theFederal Government

Monetary Policy Instruments� Two types of instruments
� Direct and Indirect
� Direct monetary policy instruments is characterized by the use
of:
� Credit ceiling, Sectoral credit allocation, administrative control of
interest and exchange rates, Moral suasion, movements of
governments account in and out of the DMBs, issuance of stabilization
securities etc.

instruments and therefore, require a well developed and
functional financial market. These Instruments include
� Open Market Operations, Liquidity Ratios, Cash Reserve ratios, Discount
window operations, Expanded Discount Window operations (EDW) –

aPolicy Framework: Transmission mechanism..cont
� Monetary policy actions affect the real economy through a
process generally referred to as the “transmission mechanism”
� It is complex, time consuming and therefore difficult to
manage (Lags)
� To achieve a goal that can not be directly measured requires
the employment of intermediate targets, or what is generally
referred to as the nominal anchor for monetary policy.

referred to as the nominal anchor for monetary policy.
� There are two kinds of nominal anchor:
� Quantity-based nominal anchor
� Price-based nominal anchor
� The quantity-based nominal anchor targets money stock while
the price-based nominal anchor targets exchange rate or
interest rate
� Currently, the CBN uses broad money supply (M2) as the
nominal anchor 10

aPolicy Framework: Transmission mechanism..cont
� The final targets of monetary policy are macroeconomic
variables, normally, the inflation rate
� These targets are not directly affected by the central bank
policy tools
� The central bank chooses another set of variables called the
operating targets (base money, reserves etc) which are more

responsive to its policy tools
� Operating and intermediate targets are used to direct the
monetary policy towards the achievement of its goals
� The criteria for choosing variable/targets include
� Measurability
� Controllability
� Ability to predictably affect goals in desired manner11

Monetary Targeting
� The Bank’s current monetary policy framework is monetary
targeting with:
� Base (Reserve) money as operating target
� Broad money supply (M2) as intermediate target
� Inflation as the ultimate or final target

� Both the operating target and intermediate target are
employed in determining the optimum level of money
stock/liquidity consistent with the assumed level of expected
output growth and inflation
� This process starts with the design of a short-term monetary
programme approved by MPC using the quantity theory of
money12

Monetary Policy Framework…cont.
� Under the monetary targeting framework in an
indirect approach, the liquidity level that is consistent
with macroeconomic objectives is determined using
� Base Money (BM) as the operating target,
� M2 as the intermediate target while inflation is the
ultimate target
� Conventionally, Base Money is made up of currency

� The Central Bank can also influence the multiplier (k) in
the desired direction 18

recent times- inflation has remained at moderate levels
