This project has traced the evolution of Nigeria’s monetary policy and its performance since the early1980’s, to provide a background to the reviews; it discussed same theoretical aspects of monetary management. On the theoretical aspect it reviewed the concepts of monetary management, the objective of monetary policy and the instruments of monetary policy. The highlights of the Nigeria economy of the 1970’s were the growing importance of oil, the expending role of the public sector in the economy and the large dependable on the external sector. Despite the family impression economic performance of the period, some economic problem such as growing fiscal pressures, assumed more serious dimensions. In the prevailing circumstances, monetary central framework and the large divergence of fiscal operation from the set monetary and credit targets. The oil boom of the 1970’s come to an end in the early 1980’s. Consequently, the development strategies, which were considered appropriate during that period, became inappropriate under the environment characterized by substantial reduction in oil import earnings and revenue. Rigorous economic controls were mounted to stain the determination in the general framework.



  • Background of the study

A policy is a statement of basic principles that provides a framework in which performance is measured. One of the principal responsibilities of the central bank of Nigeria (CBN) is the formulation, monitoring and execution of monetary stability and economic development as well as ensuring sound financial system. The central bank of Nigeria employs various instruments in caring out these responsibilities. Before 1992, the CBN was under the federal ministry of finance. This has change presently, central bank reports directly to the presidency under the central bank of Nigeria degree The CBN carries out this responsibilities on behalf of the federal government of Nigeria under the status of the central bank of Nigeria Act of 1958 and banking Act of 1967 which have been replaced with CBN Degree No. 24 of 1991 and Bankers and other financial institutions Decree (BOFID) NO. 25 of 1991. In formulating executing monetary policy, the government of the CBN is required to make proposals to the president of the federal republic of Nigeria who has the final power to accept or amend such proposals. It is after the presidency has approved it that the CBN is monetary policy proposals are made as an integral part of the federal government annual budget which combines to approve monetary policy. The aim of monetary policy may be to check inflation or to stimulate production to aid recovery from a recession. The method adopted to achieve the designed aim is through changes in the monetary supply. A policy aiming at increasing the quantity of money is inflationary, and one that aims at a contradiction of the supply of money is deflationary. Monetary policy is mainly the concern of the central bank, but the consequences of monetary policy can be so far – reaching for the whole community that no modern government can leave the choice of policy entering to its central bank. The paper will therefore examine the various instruments of monetary policy measures introduced by CBN since inception in 1959. It will therefore evaluate the effectiveness of the instruments taking into consideration the major constraints the CBN have to grapple with. The instruments used by the central bank of Nigeria to implement its monetary policy objectives can be classified broadly as direct or portfolio control approach and indirect or market interaction approach (CBN research departments). The direct control instruments place restrictions on the freedom to acquire more assets to insure liabilities. This is employed essentially because of the poor infrastructure based and low development of money (financial) and capital market over the years. The central bank has employs the following direct monetary controls. The indirect polices are usually market determined as well as use of reward system by the CBN in achieving its polices. They include the following:

Open market operation (OMO)

Moral suasion

Discount rate mechanism

Below is the brief explanation of the instruments:



The central bank of Nigeria also uses the reserve requirements of banks as an instrument of monetary policy. Banks will ordinarily, either from custom or prudence, and to keep a certain percentage of demand deposits in their bank as a reserve. They do this because of the necessary for ensuring that the bank will always have sufficient funds on hand to pay off depositors who would like to withdraw their money in the ordinary course of business. An increase in the legal reserve requirement will reduce the amount by which member banks can make loans and expand the money supply and a decrease in the legal reserve requirement will increase the amount by which member banks can make loans and expand the money supply.


Sectoral allocation of credit is aimed at ensuring that priority is accorded the growth sectors of the economy such as agriculture and the many acting industry in the allocation of credit with a view to stimulating growth in the non-oil sector.


Interest rate can be defined as the return or guild on equity or opportunity cost of differing current consumption in the future. It can also be identified as the cost of credit. In Nigeria, the interest rate structure is directly managed by the government under the advice of the making authority due to the under – developed nature of the financial market couples with the relative scarcity of capital resources in the economy. Monetary policy acts through the supply of money, as the name implies, to change interest rates and the planes of businessmen for investment. The idea is that an increase in the supply of money, just as an increase in the supply of any good, is likely to cause a decrease in the price you must pay for it. The shorter, the supply of money for low, the more businessmen who wish to borrow for investment proposed will have to pay for their fund. If the central bank of Nigeria arranges a contraction in the supply of money, the price of borrowing (the interest rate) will be accepted to rise, and higher rates increase the cost of any investment project. The final result is that planned investment tends to decline.

On the other hand, if the government can increase the supply, this will means more funds available for lending; thus the interest rate declines, and investment is encouraged.


This is a policy measure adopted by central bank or regulates the level of inflation in the economy. By this policy, CBN specifies maximum growth of credit the bank would enter to the economy.


Stabilization securities are issued by the CBN to banks at given interest rates designed to reduce banks excess cash holdings and then credit expansion. This instrument was first employed between 1976 and 1979 (CBN Research department, 1979).



This policy was intended to accelerate the business opportunities of indigenous borrowers especially doing the indigenization scheme. The guideline stipulates minimum credit that must be entered to indigenous borrowers.


In purpose of the government policy on rural banking, banks, are requires to lend a certain minimum percentage of the deport mobilized in the rural areas to borrowers in the rural areas.



Open market operations involve the central bank discretionary power to purchase or sell securities, in order to influence volume of credit and subsequently interest rates, which subsequently affects money supply. For central banks to use this toll successfully, the financial market must be well developed such that the large volume of government securities in the system will be responsive to the interest rate changes. The securities are usually short – term securities, which they sell and purchase long – term securities. Thus by altering the relative supplies of securities of difficult maturities, the CBN is able to affect the term structure of interest rate. The open – market purchase or sale of government bounds to gives the central bank of Nigeria flexible tool of monetary control. Transactions can be started, stopped, or received very quickly, and they can be made in any amount designed. Unlike change in resumes requirements, which imply very large changes in the money supply. Open – market transactions can be tailed to fit any size change the central bank of Nigeria think is called for.


This involves the use of the power persuasion to influence the tending operations of the commercial banks in the direction desired by the monetary authorities. It does not involve the issue of official directives. The government of the central bank merely uses his position to persuade and appeal to the banks to enerase restraints in credit expansion, under an inflationary situation for instance, this policy is not hand to understand, when inflation or deflation threat the CBN can use its persuasive powers to see what can be done to event then the central bank of Nigeria may adopt the following ways:

  •  Warning
  • Entorlation
  • Pleading and
  • Phone call


This is the interest rate charged by the central bank on its loans. The rate is set to reflect the banking and credit conditions available in the market. Discount rates are adjusted from time to time in the light of changing market conditions and complement (OMO) and the thrust of monetary policy generally.


Monetary policy implementation by central bank of Nigeria have some position returns if it is wisely applied, but the monetary policy becomes a problem when it conflicts among the objections and instruments of monetary policy and other policies as well as the constraints if faces. The inadequate implementation of the varies policies as well as constraints faces. The inadequate implementation of the various policies as well as constraints if faced. The inadequate implementation of the various policies are as well as inconsistency in such policies have been the major problems of monetary policy in Nigeria Fiscal deficits of the federal government in the recent past have been but out of time with monetary target largely because of improper co – ordination of the fiscal and monetary programme. Fiscal imbalance has adverse consequences on the monetary base and the effective use of indirect tools.


The objectives of the study are;

The major objective of this present study is to ensure monetary policy issued and its implementation by the CBN Above the entire major problem encountered in its implementation is a major objective of this study. The study is to pay attention in the following issues:

  1. The monetary policy objectives and philosophy
  2. The various policy instruments called instrumental variables used by CBN in monetary policy.
  3. Constraints in policy formulation and execution
  4. Evaluation of impact of financial policy reforms especially the policy of deregulation of the banking system on the economic performance of the ratio.
  5. Targets and indicatives of monetary policy
  6. Recommendation in improving policy guideline

For the successful completion of the study, the following research hypotheses were formulated by the researcher;

H0:   There are no inherent problems in the implementation of the monetary policy in Nigeria by central bank of Nigeria.

H1: There are no inherent problems in the implementation of the monetary policy in Nigeria by central bank of Nigeria.

H02:  The major tool of central bank has not been more of direct policy than indirect policy measure.

H2:  The major tool of central bank has been more of direct policy than indirect policy measure.



The significance of this study is geared towards exposing to the populace the instruments used by the central bank of Nigeria in monetary policy implementation. This study is also to expose what monetary policy is all about and why it should be implemented. This project will also enlighten the reader of the existence of problems associated with the monetary policy implementation by the central bank of Nigeria. Furthermore, after the above analysis we will set a challenging face for the central bank of Nigeria to check if they are improving or not improving. This study on conclusion will expose suggested ways by which the problems of monetary policy implementation could be solved. Finally, this project will provide for any student researching on problems of monetary policy implantation by CBN a solid foundation for realization of his/her research purpose.




The scope of the study covers problems of monetary policy implementation by central bank of Nigeria. The researcher encounters some constrain which limited the scope of the study;

  1. a) AVAILABILITY OF RESEARCH MATERIAL: The research material available to the researcher is insufficient, thereby limiting the study
  2. b) TIME: The time frame allocated to the study does not enhance wider coverage as the researcher has to combine other academic activities and examinations with the study.
  3. c) Organizational privacy: Limited Access to the selected auditing firm makes it difficult to get all the necessary and required information concerning the activities





  1. CENTRAL BANK OF NIGERIA: This is the government bank in charge of monetary policy and the supervision of commercial banks in Nigeria.
  2. MONEY: Broad term consisting of coins, paper notes, and demand deposits of commercial banks.
