Do Monetary Policy Announcements Affect Exchange Rate Returns and Volatility of Returns? Some Evidence from High‐Frequency Intra‐Day South African Data

This paper examines the temporal effect of domestic monetary policy surprises on both returns and volatility of returns of the South African rand/U.S. dollar exchange rate. The analysis in this “event study” proceeds using intra‐day minute‐by‐minute exchange rate data, repo rate data from the South African Reserve Bank's scheduled monetary policy announcements, and market consensus repo rate forecasts. A carefully selected sample over the period August 2003 to November 2017 ensures that the change in monetary policy is exogenous to the exchange rate. We find statistically and economically significant responses in intra‐day high‐frequency South African rand/U.S. dollar exchange rate returns and volatility of exchange rate returns to domestic interest rate surprises, but anticipated changes have no bearing on exchange rate returns and their volatility. The empirical results also indicate that there is an instantaneous response of the rand/dollar exchange rate to monetary policy surprises and that monetary policy news is an important determinant of the exchange rate until at least 42 minutes after the pronouncement – suggesting a high degree of market “efficiency” in its mechanical sense (although not necessarily in the deeper economic‐informational sense) in processing this information. Essentially, the asymmetric GARCH results exhibit no leverage effects – positive and negative information shocks have symmetric effects on conditional variance.     

INFLATION TARGETING AND THE FISHER EFFECT IN SOUTH AFRICA: AN EMPIRICAL INVESTIGATION

The paper analyses the relationship between expected inflation and nominal interest rates during a period of inflation targeting in South Africa, i.e. from 2000 to 2005. Specifically, it investigates the Fisher hypothesis that nominal interest rates move one‐to‐one with expected inflation, leaving the real interest rate unaffected. The analysis distinguishes between a short‐run Fisher effect and a long‐run Fisher effect. Using cointegration and error correction models (for monthly data for the period April 2000 to July 2005), it was found that the short‐run Fisher hypothesis did not hold during the relevant period under the inflation targeting monetary policy framework in South Africa. This is attributed to a combination of the South African Reserve Bank's (SARB) control over short‐term interest rates and the effects of the monetary transmission mechanism. The long‐run Fisher hypothesis could not be confirmed in its strictest form: while changes in inflation expectations move in the same direction as the nominal long‐term interest rate. This suggests that monetary policy has an influence on the real long‐term interest rate, which has positive implications for general economic activity, thus confirming the credibility of the inflation targeting framework.     

Monetary Policy Implementation and Volatility Transmission Along the Yield Curve: The Case of Kenya

This paper analyses the degree to which volatility in interbank interest rates leads to volatility in financial instruments with longer maturities (e.g. T‐bills) in Kenya since 2012, year in which the monetary policy framework switched to a forward‐looking approach, relative to seven other inflation targeting (IT) countries (Ghana, Hungary, Poland, South Africa, Sweden, Thailand and Uganda). Kenya shows strong volatility transmission and high persistence similar to other countries in transition to a more forwardlooking monetary policy framework. These results emphasize the importance of a strong commitment to an interbank rate as an operational target and suggest that the central bank could reduce uncertainty in short‐term yields significantly by smoothing out the overnight interest rates around the policy rate.     

Chinese monetary policy and the banking system

Chinese monetary policy differs from that of many other countries in its use of multiple policy instruments. This paper assesses the effectiveness of some of the instruments employed, using a model of the banking sector and elasticities estimated from Chinese data. We find that direct interest rate changes are a poorer instrument of monetary control in China than changes in reserve requirement ratios and loan-to-deposit ratios. This finding is based on the ambiguous estimated response of deposit demand to such changes, and may help to explain why changes to administered interest rates have been used sparingly as an instrument of Chinese monetary policy. We also find that the ambiguous deposit demand response could pose challenges for the effectiveness of open market operations under interest rate liberalisation, while exchange rate liberalisation is likely to make monetary instruments more powerful.     

Simple credibility tests of the ERM bands for the pound sterling and the Italian lira

This article presents evidence that the European Monetary System (EMS) bands for the Italian lira and the pound sterling were not credible for most of the period 1990–1992, and especially during the week prior to their withdrawal from the EMS system. Using a simple test, developed by Svensson, domestic interest rates for both Italy and the United Kingdom have been found to be mostly outside the rate-of-return bands implied by the official arrangements of the EMS target zone system. Furthermore, comparing implied forward rates for various maturities with the official EMS bands of both currencies, we again found that the followed monetary policies in both countries were not in general consistent with those needed to maintain an orderly functioning of the (EMS) system. The Svensson test can further be used as an indicator of potential speculative attacks on an EMS currency, and, in turn, as a signal of an emerging need to adjust the corresponding country's monetary policy.     

The case for price level or inflation targeting—What happened to monetary policy effectiveness during the Japanese disinflation?

This paper examines whether price level or inflation targeting would have been appropriate policy choices for Japan during its disinflation and deflation period. We employ Markov switching and structural vector autoregressions, together with structural IS equations, to investigate monetary policy effectiveness during the Japanese disinflation. We find evidence of regime switching in the mid-1990s in a model including the nominal policy interest rate. When monetary policy shocks are identified by using the McCallum rule for monetary base, a monetary expansion is found to have a statistically significant impact on prices. Moreover, a lower real ex ante interest rate can still stimulate the economy despite the zero lower bound on nominal interest rates.     

Some Evidence on the Relevance of Bank Behaviour for the Lending Channel in The Netherlands

This paper studies the behaviour of Dutch banks. We test the adjustment of banks' balance sheets in times of monetary policy changes during the period 1957–1991. As a reaction to a policy change, banks basically have two alternatives to adjust their net money creation: (1) sell securities in public capital markets, and/or issue long-term liabilities, and (2) change domestic loan supply. If banks opt for the latter a lending channel may be relevant, even in a small open economy with a fixed exchange rate and a high degree of international capital mobility. We test for the effectiveness of both indirect and direct instruments of monetary policy. It turns out that in case of changes in the official interest rate, the volume of bank loans is not affected and that banks display a kind of buffer-stock behaviour by diminishing their publicly traded assets. In situations with quantity restrictions on the growth of net money creation, however, the volume of loans is affected significantly when the quantity restriction is withdrawn thereby fulfilling a necessary condition for the bank lending channel to be effective.     

Japan’s quantitative monetary easing policy: Effect on the level and volatility of yield spreads

We examine the effects on the level and volatility of yield spreads of the Quantitative Monetary Easing Policy (QMEP) of the Bank of Japan (BoJ) implemented from March 19, 2001 to March 9, 2006. We adopt an Exponential Generalized Autoregressive Conditional Heteroskedasticity (EGARCH) model to analyze daily data for the five year duration of QMEP. The purpose of QMEP was to reduce short-term interest rate expectations with the goal of bringing down long term interest rates to stimulate the economy. Under QMEP, the operational target of monetary policy was taken as the current account balances (CABs) of financial institutions held at the BoJ. In support of QMEP effectiveness, we find that the policy to raise CABs was indeed associated with a decrease in yield spreads across all maturities. At the same time, the policy may have increased the volatility of yield spreads at short and medium time horizons, perhaps due to unevern demand for government security issues that nevertheless left confidence in the future of low interest rates intact. Preserving liquidity at or above the CABs target range was found to decrease yield spreads.     

The real effects of monetary policy in China: An empirical analysis

This paper examines whether institutional changes have affected the interaction between the real economy and monetary policy in China. We find evidence that structural changes in the financial and real sectors over the period of our study did influence the way in which monetary policy affected the real economy. There were an increasing influence of interest rates on output over 1984 to 1997 and non-state owned enterprises were increasingly reacting to monetary policy changes, suggesting that banking sector reforms were having effects, despite the fact that most credit was allocated to the loss-making State sector.     

LOUD AND CLEAR? CAN WE HEAR WHEN THE SARB SPEAKS?

Inflation targeting is a forward‐looking framework for monetary policy that has brought unprecedented transparency to the process of monetary policy. This paper aims to assess the degree to which the South African Reserve Bank's (SARB) Monetary Policy Committee (MPC) has, since the introduction of inflation targeting, successfully communicated to the public its policy analysis, and, in particular, the expected future policy changes. It follows international literature in constructing a numerical index that is used to reflect the information content of the SARB's communications, specifically the monetary policy statements that accompanied each of the MPC meetings since 2000. This method allows us to judge, systematically, the degree to which the MPC has communicated successfully, and the evolution of that success over the past nine years. We find evidence that the MPC has succeeded in signalling their likely future policy decision with consistency over this period.     

Purchasing Power Parity Between the UK and Germany: The Euro Era

We use the Johansen cointegration approach to assess the empirical validity of the purchasing power parity (PPP) between the UK and Germany since the introduction of the euro. We conduct the empirical analysis in the context of the global financial crisis that began in 2007 and find that it directly affects the cointegration space. We fail to validate the Johansen and Juselius (1992) original hypothesis that nonstationarity of PPP associates with the nonstationarity of interest rate differentials to produce a stationary relation. On the other hand, we do not reject PPP. We find that PPP cointegrates with inflation differentials. We also find, contrary to conventional wisdom, that (i) equilibrium adjustment occurs between the German and UK inflation rates, while weak exogeneity exists for the German and UK interest rates and the PPP condition, and (ii) three common trends associated with the German interest rate the UK interest rate, and the PPP condition “push” the system with the German interest rate and the PPP condition playing dominant roles in affecting inflation in both Germany and the UK. These results cast serious doubt on the presumed independence of the UK monetary policy.     

Monetary Policy Impulses and Retail Interest Rate Pass‐Through in Asian Banking Markets

This paper considers the integration of financial markets and mutual influences of monetary policies in the USA and Asia based on monthly data from 1994 to 2007. We used panel‐type and time‐series and quantile panel‐type error correction models to test the influences of expected and unexpected monetary policy impulses on the interest rate pass‐through mechanism in the financial markets of 9 Asian countries and the USA. The empirics show that if interest rate integration exists in the financial markets, the following effects are observed: (i) positive impulses of unexpected monetary policy will lead to an increase in the long‐run multiplier of the retail interest rate; (ii) the adjustment of retail interest rates with short‐run disequilibrium will lead to an increase in the long‐run markup; and (iii) the empirical results of quantile regression prove that when the interest variation is greater than the 0.5th quantile and unexpected monetary policy impulses are greater than the expected monetary policy impulses, the short‐run interest rate pass‐through mechanism becomes more unstable.     

The lending channel of monetary policy in Indonesia

This study evaluates the bank lending channel of monetary policy in Indonesia by using quarterly bank-level data over the period of 2005-2016. I find that the lending channel of monetary policy works for all banks, both large and small. The results suggest that higher capital buffers and better liquidity positions moderate the impact of changes in monetary policy on credit growth for large banks, while capital buffers and liquidity positions do not alter the strength of the lending channel for small banks. The findings indicate that the central bank can use prudential instruments affecting capital buffers and liquidity positions for managing the strength of adjustment in the monetary policy interest rate on bank credit growth.     

International monetary transmission in East Asia: Floaters,non-floaters,and capital controls

This paper analyzes the impacts of the United States (US) monetary shocks on East Asian countries using structural vector-autoregression (VAR) model. We find that the impacts of the US monetary shocks on East Asian domestic interest rates and exchange rates contradict conventional wisdom. The conventional exchange rate channel is unlikely to play much role in the transmission of the US monetary policy shocks to floaters in East Asian countries, excluding Japan. In these countries, the domestic interest rates respond strongly to the US interest rate changes, by giving up monetary autonomy, probably because of fear of floating. However, the domestic interest rate does not respond much in countries with fixed exchange rate regimes and capital account restrictions, such as China and Malaysia. This may suggest that the countries with fixed exchange rate regimes enjoy a higher degree of monetary autonomy, most likely with the help of capital account restrictions.     

Monetary policy shocks and interest rates: Further evidence on the liquidity effect

Monetary Policy Shocks and Interest Rates: Further Evidence on the Liquidity Effect. — This essay tests whether innovations in monetary policy are inversely linked with changes in interest rates. Using Mishkin’s efficient markets framework and the measures of policy innovations constructed by Boschen and Mills and Bemanke and Mihov, we find strong evidence that expansionary monetary policy shocks lower interest rates. We argue that the failure of most studies to find a significant liquidity effect is due to the endogeneity of the monetary aggregates which are used to measure policy shocks.     

宏观经济对利率期限结构的动态影响研究

本文通过结构VAR模型发现宏观经济冲击对各期限利率水平产生显著的影响,但不同类型的冲击产生的影响不同：与成熟市场相似,90％以上的利率曲线变化可以由水平、倾斜和曲度因素来解释,且更多表现为平行移动;利用脉冲反应和方差分解,发现价格水平对水平因素的影响最大,而货币政策变化是倾斜因素和曲度因素变化的主要原因,这既体现了央行货币政策操作的有效性,也表明现阶段银行间市场利率期限结构的信息敏感性。这与成熟市场的表现是非常相似的。     

Learning the fiscal theory of the price level: Some consequences of debt-management policy

This paper examines the consequences of the scale and composition of the public debt in policy regimes in which monetary policy is ‘passive’ and fiscal policy ‘active’. This configuration of policy is argued to be of both historical and contemporary interest, in economies such as the US and Japan. It is shown that higher average levels and moderate average maturities of debt can induce macroeconomic instability for a range of policies specified as simple rules. However, interest-rate pegs combined with active fiscal policies almost always ensure macroeconomic stability. This suggests that in periods where the zero lower bound on nominal interest rates is a relevant constraint on policy design, a switch in fiscal regime is desirable.     

Transmission mechanisms of conventional and unconventional monetary policies in open economies

This paper provides an empirical examination on the transmission mechanisms of conventional and unconventional monetary policies for two non-EMU countries, Switzerland and the United Kingdom, over the period 1990–2017. We investigate the role of stock prices and consumer expectations in the transmission of monetary policy. We propose two distinct structural VAR models. The model for the case of conventional monetary policy covers the pre-2009 period, while the model for the case of unconventional monetary policy covers the post-2009 period. The official bank policy rate and central bank’s reserve assets are used as instruments for conventional and unconventional monetary policy. The analysis reveals that the inclusion of a forward-looking informational variable of near-term development in economic activity and a financial variable such as the stock prices is of key importance for the monetary policy assessment. We provide evidence for the existence of a consumer confidence channel in the transmission of conventional monetary policy. Moreover, the long-term government bond yields, the exchange rate and stock prices have an important role in the transmission of unconventional monetary policy. Our findings indicate that conventional and unconventional monetary policies have short-run expansionary effects in both countries by increasing output, consumption, investment, stock prices and wages, while reducing unemployment.

     

Can inflation targeting regimes be effective in developing countries? The Turkish experience

This paper examines the performance of Turkey's inflation targeting (IT) experience. We find the IT regime to be an effective framework. Our judgment is based on three broad conclusions supported by empirical analyses. First, fiscal stability is an effective tool for a successful monetary policy. Second, the overnight policy of the Central Bank of Turkey rate is a significant determinant of the changes in market lending rates, which is the preliminary step in the monetary transmission mechanism. Third, recent developments on the broader issue of the effectiveness of interest rate policy in controlling inflation through aggregate demand management and through other channels are encouraging. Based on our findings, we argue that the impact of policy rate changes on economic activity and inflation have become more predictable and changed in the direction in line with theory, improving the transmission capacity of monetary policy.     

The interest rate–inflation relationship under an inflation targeting regime: The case of Turkey

This paper examines the relationship between nominal interest rates and the expected inflation rate for the Turkish economy between 2002 and 2009, a period when the inflation-targeting regime was implemented as monetary policy. We use the test of cointegrating rank with a trend-break (a method introduced by Inoue, 1999) and we also apply exogeneity tests. Empirical findings indicate that monetary policy rates depend on inflationary expectations; long-term interest rates are affected by monetary policy; and the weak form of the Fisher effect is valid. This evidence implies that monetary policy has actually influenced the real long-term interest rates; the inflation targeting regime pursued by the Central Bank of Turkey is reliable; and hence realized inflation has remained close to its targeted level.
