The origin of central banking system can be traced back to 1694 when the Bank of England came into being as the first ever central bank. The bank was established to help King William III out of his government's financial crisis but it did not behave as a lender of last resort until much later (See Lovell, 1957)1.
Central banking has undergone a remarkable change during the last decade. The new paradigm in monetary policy appears to be central bank self-governing and transparent.
First of all let's see what central bank and transparency means, a central bank is a Government agency that performs a number of key functions: (1) central bank is the only bank which has the authority to issue currency on behalf of its nation; (2) central bank has authority to increase and decrease the supply of credit in the economy which controls the interest rates; (3) manages the external value of its currency in the foreign exchange markets; (4) central bank holds a percentage of deposits as reserves of other banks and other central banks so as to reduce the risk of banks overextending themselves and suffering from bank runs, (5) acts as Fiscal Agent for the central government, when the government sells new issues of securities to finance its operations; and (6) The central bank also plays a vital role of reserving the nation's emergency funds, and it is because of this the central bank is called "lender of last resort".
Transparency in the physically meaning, transmitting light, in the conceptually meaning, clarity, in the economically meaning, symmetric information, and in the practically meaning, openness, honesty, clarity, common understanding2. We can say that central bank is a combination all these that is, it openly correspond or communicates important and necessary information to the investors, shareholders and the public in short "absence of asymmetric information between central bank and other economic agents". Therefore a central bank is said to be transparent when there is less or no information asymmetry. Moreover a central bank is said to be transparent if its actions are easily identified, its policies are readily understood, and its statements are honest or true.
"A central bank is transparent when it provides at all times sufficient information for the public to understand the policy regime, to check whether the bank's actions match the regime and to pass judgment on its performance."3
Over the past years, financial institutions have tried to implement various strategies to increase its transparency. One of the important strategies among these is, disclosure of information in published accounts has been prominent even though it was present but less prominent. A great amount of focus was given towards economic policymaking so as to become more transparent - particularly with respect to monetary policy, inflation targeting a very transparent monetary policy regime was adopted by and a number of central banks, including Sweden's Riksbank and Britain's Bank of England. Yet, few other countries like the United States have not yet subscribed to inflation targeting, but the Fed has also become much more transparent about its policymaking and operations over the past 15 years. The New Basel Accord (Pillar 3) has introduced a number of disclosure requirements that aim to improve the market's ability to assess a bank's risk and value.
The drift towards central bank being more transparent can be easily seen in our day to day life by casual observation. Some of the prominent examples of various central banks who have given great importance to becoming transparent are the central banks of New Zealand, Canada, the United Kingdom and Sweden. These few nations have adopted a framework of 'inflation targeting' from the early 1990s itself, which is characterized by an explicit inflation target and the publication of inflation forecasts.4 Many others countries have even started to give importance to having adopted greater openness as well, even if it's not in the form of inflation targeting or inflation forecasting. The few other central banks which have adopted this includes central banks in emerging markets like Brazil, the recently founded European Central Bank (ECB), and even the well established central banks like those of the United States, Japan and Switzerland.
"Consider the legions of economists whose sole function it is to interpret U.S. Federal Reserve Chairman Alan Greenspan's every twist and turn of phrase so as to divine which way the monetary winds are blowing."
- Caroline A. Baum, The Last Word p.645
From the above phrase, two important points can be looked upon; one is that by trying to assume what the actions of monitory policy will be the resources are used up. The other is that statements are being made by the central bank that might yield some insight into its future plans, but the messages are not typically transparent.
The economic policy outcome can easily be identified to a great extend by the increased transparency on central bank through various channels. It cannot be assumed that all the aspects points out the same way. Moreover, central bank transparency cannot be universally defined in all aspects6. The concept of transparency differs from authors to author in various ways, some may focus mainly on the decision-making process, while some others may focus on various other aspects like models, preferences, and even more some may look into the knowledge about the shocks hitting the economy, or the implementation of policy decisions.7
The private information's about the central bank's objectives or intentions can be easily assumed from the models derived by Faust and Svensson (2000, 2001), Jensen (2000), Geraats (2001a), and Tarkka and Mayes (1999). The model by these eminent economist states that, "transparency is modeled as the degree of asymmetric information about control errors (Faust and Svensson (2001) and Jensen (2000)) or (anticipated) economic shocks reflected in the policy instrument" (Cukierman (2000a,b) and Tarkka and Mayes (1999)).
Kuttner and Posen (2000) yet another eminent economists explains about the reduction of exchange rate volatility when there was a shift in the Federal Reserve's and the Bank of Japan's degrees of transparency.8 In addition to this, political pressures, increased accountability, facilitation of fiscal and monetary policy co-ordination, and improved internal organization of central bank analysis is yet another arguments in favor of transparency in monetary policy.9
Analytically, the three different regimes of transparency that is the least transparent, highly transparent and the extreme transparent are being distinguished by Faust and Svensson (2001). In the first regime, that is the least transparent, neither the employment goals nor the intentions of the central bank can be seen by the public. Inflation intentions of the central bank can be easily observed by using the second regime that is highly transparent. As a result of this increased transparency in inflation intentions there arises a lower inflation rate because the sensitivity of a central bank is increased which in-turn increases the reputation to its actions, making it more costly for the central bank to pursue a high-inflation policy. In the extreme transparency regime, that is the third according to the author, both the intentions of the central bank as well as the employment goals can be seen. The central banks reputation as well as its actions are no longer conveyed about the inflation bias. Higher inflation, inflation volatility and unemployment variability can be reached at as a result of inflationary bias.10
Yet another similar structure to Faust and Svensson (2001) was adopted by Jensen (2000) assuming that central bank is informed privately about its output target and that public's capacity to assume the inflation control error is greater. On comparison with Faust and Svensson (2001), who's main focus was on the future credibility effect of central bank, while Jensen (2000) focus was towards the marginal cost of inflation within the current period with the help of new Keynesian elements (staggered price-setting and monopolistic competition). Due to this increase in the transparency, there was an increase in the discipline and credibility to the reputational costs of deviations from the inflation target.
According to some of the eminent economist, transparency is not only the tool used for independent central banks to be held accountable, but it is often argued that the economic point of view too can be desirable from it. The effect of central bank being transparent is being immensely discussed by various policymakers and researchers. Although most of the literature tends to favor transparency of central bank, it's not the case, the debate still continuous whether or not central bank should be transparent or not. Most of the practical and observed research concludes that the transparency maintained by central bank previously were desirable from an economic point of view.
An important question to be asked is, whether central banks pushing toward more disclosure of information are beneficial or not. Indeed, there are a number of good reasons to it. First, it can be argued that banks from the early time itself are opaque institutions, and increase in disclosure might not change this opaqueness.
Second of all, transparency might not necessarily be reached at by just simply increasing the quantitative disclosures. In the words of Federal Reserve Chairman Alan Greenspan: "A more complex question is whether greater volume of information has led to comparable improvements in transparency of firms. In the minds of some, public disclosure and transparency are interchangeable. But they are not. Transparency challenges market participants not only to provide information but also to place that information into a context that makes it meaningful" (Greenspan 2003, p. 7).11
Third, disclosure is costly. Clearly, "requiring disclosure of information imposes a cost on banks, as on any firm, and this cost must be offset by resulting benefits for it to be justified" (Schaffer 1995, p. 26).12 Publishing information and producing information are some of the direct cost involved in the cost of disclosure, even though these are the direct cost involved, when a bank publishes its information in the financial market, there arises a threat of its competitors exploiting the information which might result in indirect cost.
Cukierman and Meltzer (1986) eminent economists developed concept of central bank transparency13. Bankers, mainly the central banks use of monitory policy control was in great fault or imperfect in order to hide their intentions. In other words, the absence of transparency with control error was evident to meet the central banks objective, at least possible reputation cost. More recently, with the setup from the Cukierman and Meltzer, Faust and Svensson (1999) was able to differentiate more between transparency and control error. Central bank chose the pair that maximizes it objective and it was to be opaque.
There are still some argument that incomplete transparency is optimal, as by being incomplete optimal, the central bank's ability to control inflation has to be balanced against the private sectors wish to see price stability, employment and output.(see for example Faust and Svensson, 2001 or Jensen, 2000). Others argue that for operational reasons, it is important to have certain restrictions on transparency. The main idea behind this is to differentiate between the 'need to know' (see Eijffinger and Hoeberichts, 2002) and 'the need to understand' factor (Issing, 1999) and to reinforce the Bank's credibility.
There are yet more evidence of central bank being transparent and central bank transparency being one of the important feature of monetary policy, which is been recorded in one of the most comprehensive survey being conducted till date on monitory policy of central bank. It's been recorded in the 1998 survey of 94 central banks by Fry, Julius, Mahadeva, Roger and Sterne (2000). This survey discloses that about 74% of central banks consider transparency as a vital or very important component of their monetary policy framework, only exceeded by central bank independence and the maintenance of low inflation expectations (with 83% and 82%, respectively; Fry et al. (2000, p. 135)). Subsequently, the relevance of transparency have only increased when certain changes are being done by central bank.
According to one of the famous journalist, Caroline A. Baum, she says that from the phrase given by Alan Greenspan, the U.S. Federal Reserve chairman, the resources are being used up at the same time the statements made by the central bank are far too less transparent. What it means to say is that the central bank should be more transparent enough so that its monitory policy at the same time its future plans can be easily understood by even a layman who might have little knowledge about the norms and policies of the central bank.
By central bank being more transparent, the economic policy outcome can be know to a certain extend through various means, but it cannot be said that by central bank being transparent, all the aspects related to it can be easily viewed at. The concept of transparency differs from person to person, while so concentrate on the decision making process, others may look into the fact of policy making etc. Therefore it can be said that there is no universal meaning to central bank and varies from person to person and country to country. For example the transparency of central bank in India might not be same as the transparency in England besides taking into some common facts.
According to some of the eminent economist, central bank should have an optimal degree of transparency mainly for the monitory policy, but on analysing the facts by few others about whether central bank should be more transparent or not, two aspects can be taken into account, one is the uncertainty and the other is information overload. If central banks becomes more transparent, it could lead to uncertainty, that is, when lots of information are provided to the public, they tend to look at the complexity of monitory policy making and the uncertainly around it which might not be as complex as it seems to be. The second is the high degree of information overload or confusion. If large amount of information is being disclosed to the public, there is a high risk of information getting overloaded or confused. Therefore analyst say central bank should have an optimal transparency.
Kuttner and Posen states that when central bank becomes more transparent, there is less volatility in the exchange rate. Yet other important factors supporting central bank transparency are the fiscal and monitory policy coordination, political pressures, accountability etc.
According to Faust and Sevensson, transparency can be segregated into three divisions, the least transparent where in the public does not know about the employment goals as well as the intentions, this has also been stated by Cukierman and Meltzer. In the second division, that is if central bank in highly transparent, the inflation intention can atleast be know by the public and finally in the case of extreme transparency, both the intentions as well as the employment goals can be seen.
It can seen that Jensen another eminent economist has also taken up a similar structure to that of Faust and Svensson where the difference is that while Faust and Svensson focus on the future credibility effect of central bank, Jensen's focus was on the marginal cost of inflation.
Some argue that by increasing its disclosure doesn't completely increase the transparency, to support this economist states that banks have been an opaque institution from the past itself. Greenspan says that transparency is not reached at by just simply giving quantitative disclosure; it should be both quantitative and at the same time should be relevant and meaningful. Moreover disclosure is costly, that is when central bank publishes information, it incur cost both direct and indirect.
Some other economist (Eijffinger and Hoeberichts and Issing) states that central bank should transparent in such a way that the information which should be known to the public should be disclosed rather than disclosing all the information.
The dispute whether central bank should be more transparent or not is still being discussed immensely by various researchers and policymakers. Most of the economist favour central bank being transparent, as well as according to the study done, it can be understood that central bank being transparent will give a clear cut information to the public regarding the various monitory policies, its decision process as well as its goals and intentions. Moreover by central bank being transparent, it reduces the macroeconomic uncertainty like the interest rates, inflation etc, promotes financial stability and mainly helps the central bank to stand out from the various other banks that is being independent.
