Dynamics of Money Market Interest Rates in Ghana: Time-Frequency Analysis of Volatility Spillovers

As the second longest practicing inflation targeting economy in Africa, it is of interest to investigate the degree to which policy interest rate influences other money market rates so as to gauge the overall effectiveness of monetary policy transmission in Ghana. This study evaluates the degree of connectedness among money market rates and also determines the most dominant money market rate(s) in Ghana. The basic finding is that the monetary policy rate has a low-to-moderate influence on volatility dynamics of other money market rates in Ghana across historical time-interval and time-frequency domains. This is a reflection of a generally weak capability of policy interest rate to drive other market rates in Ghana. Both monetary policy rate and Treasury bill rate are net transmitters of shocks, while interbank, lending and saving rates are net receivers of shocks in the money market. However, the Treasury bill emerges as the largest shock transmitter in the money market, across all forecast horizons and analytical domains. The lending rate is the largest shock recipient in the money market, largely from the Treasury bill rate which suggests ample evidence of fiscal dominance in Ghana. The study accentuates the exigency for monetary and fiscal policies to expeditiously address the domestic structural bottlenecks, especially in the financial sector and the fragile fiscal profile, in order to strengthen policy transmission in Ghana.     

Dual-track interest rates and the conduct of monetary policy in China

China has a dual-track interest-rate system: bank deposit and lending rates are regulated while money and bond rates are market-determined. The central bank also imposes an indicative target, which may not be binding at all times, for total credit in the banking system. We develop and calibrate a theoretical model to illustrate the conduct of monetary policy within the framework of dual-track interest rates and a juxtaposition of price- and quantity-based policy instruments. We show the transmission of monetary policy instruments to market interest rates, which, together with the indicative credit target in the banking system, ultimately are the means by which monetary policy affects the real economy. The model shows that market interest rates are most sensitive to changes in the benchmark deposit interest rates, significantly responsive to changes in the reserve requirements, but not particularly reactive to open market operations. These theoretical results are verified and supported by both linear and GARCH models using daily money and bond market data. Overall, the findings of this study help us to understand why the central bank conducts monetary policy in China the way it does, using a combination of price and quantitative instruments with differing degrees of potency in terms of their influence on the cost of credit.     

SOUTH AFRICAN MARKET VOLATILITY,ASYMMETRY AND RETAIL INTEREST RATES PASS‐THROUGH

The purpose of this paper is to examine the interest rate transmission mechanism for South Africa as an emerging economy in a pre‐repo and repo system. It explains how the money market rate is transmitted to the retail interest rates both in the long run and short run, and tests the symmetric and asymmetric interest rate pass‐through using the error‐correction model (ECM) and the adjusted ECM‐exponential generalised autoregressive conditional heteroscedasticity (ECM‐EGARCH) (1,1)‐M methodology. This permitted the examination of the impact of interest rate volatility, along with the leverage effect. An incomplete pass‐through is found in the short run. From the entire sample period, a symmetric adjustment is found in the deposit rate, which had upward rigidity adjustment, while an asymmetric adjustment is found in the lending rate, with a downward rigidity adjustment. All the adjustments supported the collusive pricing arrangements. According to the conditional variance estimation of the ECM‐EGARCH (1,1), negative volatility impact and leverage effect are present and influential only in the symmetric deposit interest rate adjustment process in South Africa.

Why floating exchange rates fall: A reconsideration of the liquidity trap

In the international capital market, interest rates would seem to be natural shock absorbers for balancing currency risk associated with expected inflation or differential taxation. Under a floating exchange rate, however, short-term interest rates in each national money market behave as if caught in a liquidity trap. The problem arises because the domains for national monetary circulation remain somewhat disjoint even though the bond market is fully integrated internationally. The national rate of interest is ncapable of equilibriating the domestic money market on the one hand and the international bond market on the other. The result is excessively high exchange-rate volatility that distorts the flow of international commodity trade and causes cycles of inflation and deflation in open economies.     

Reserve requirements,currency substitution,and seigniorage in the transition to European monetary union

This article considers a transition toward European monetary union that combines increased substitution of currencies and greater monetary, financial, and fiscal policy coordination. It explores how such a transition would affect national inflation and interest rates and required reserve ratios when governments depend in part on seigniorage funding for public expenditures. We find that greater coordination of policies would lead to lower inflation and interest rates but higher reserve-requirement ratios. Because higher reserve-requirement ratios could place European banks at a competititve disadvantage, we conclude that the interaction between reserve requirements and seigniorage concerns makes it less likely that the gradualist approach of the Maastricht treaty is a sustainable means of transition to European union.     

Exchange rate volatility and its impact on the transaction costs of covered interest rate parity

This paper provides empirical evidence on the linkage between foreign exchange market volatility and daily 90-day covered interest rate parity (CIP) conditions of the three major exchange rates against the US dollar (US$). Markov regime shifting models were utilized to generate time series of volatility regime probabilities and these were used to explain the first and second moments of the daily deviations from and the transaction cost bands around the covered parity conditions. We find a significant positive relationship between the deviations and the regime probabilities, indicating an increasing probability of higher volatility state being associated with rising deviations (both first and second moments) from the parity condition. Similar positive relationship is found for the transaction bands. Rising (falling) probabilities of high (low) volatility regimes increased the first and second moments of the bands. Furthermore, we find a higher volatility state combined with a US$ depreciation is associated with significantly higher volatility in the daily deviations than an appreciation. Also, US$ depreciation is associated with widening transaction bands. This suggests that the level of market uncertainty was higher when the US$ was depreciating.     

Hot Money Flows,Commodity Price Cycles and Financial Repression in the USA and China： The Consequences of Near-zero US Interest Rates

Under near-zero US interest rates, the international dollar standard malfunctions. Emerging markets with naturally higher interest rates are swamped with hot money inflows. Emerging market central banks intervene to prevent their currencies from rising precipitately. They lose monetary control and domestic prices begin inflating. Primary commodity prices rise worldwide unless interrupted by an international banking crisis＇. This cyclical inflation on the dollar＇s periphery only registers in the US core eonsumer price index with a long lag. The zero interest rate policy also fails to stimulate the US economy as domestic finaneial intermediation by banks and money market mutual funds is repressed. Because China is forced to keep its interest rates below market-clearing levels, it also suffers from finaneial repression, although in a form differing from that in the USA.     

European Business Fluctuations in the Austrian Framework

The Austrian theory mainly deals with analyzing the effects of an increased credit offer on productive structures. In this respect, we propose to link long-term growth cycles to various short-term interest rate gaps. Are European Business Cycles affected when a fall in the money market rate disrupts agents’ expectations of inflation? Using the hypothesis that individual speculation is motivated by the difference between short-term real interest rates and their natural levels, we argue that Wicksellian interest rate gaps can account for a high proportion of long-term fluctuations in four European countries (Germany, France, Italy, and Spain). We present specific dating methods and filters used in order to distinguish between short-term and long-term growth cycles. The Wicksellian incentives we constructed are then significantly linked to long-term business fluctuations. Under the hypothesis of adaptive expectations of inflation, our results are enhanced.     

The Effects of Central Banks’ Rate Change Patterns on Financial Market Variables

This study examines whether different patterns of change to the benchmark interest rates of central banks are associated with their contributions to variances in the forecast errors of three financial market variables: the long-term interest rate, the foreign exchange rate, and the stock market index. On average, the central bank’s interest rate accounts for approximately 20% of the variance in each variable. We find that the total range of changes is more important than the frequency of changes. The panel regression shows that the range and frequency of policy rate changes is positively associated with the volatility of long-term interest rates but no association with the volatility of stock prices and exchange rates. These results suggest that small and frequent adjustments of policy rates are desirable for reducing the volatility of interest rates. The panel VAR represents interest rate channel is a more important than exchange rate and stock price channel.     

Volatility spillover effects in interbank money markets

Using daily data from 2006 to 2015, this paper applies alternative multivariate GARCH models and a modified version of the spillover index methodology proposed by Diebold and Yilmaz (Int J Forecast 28(1):57–66, 2012) to test the existence of shock and volatility contagion effects across interbank money markets. Overall, we find evidence that money markets are highly interrelated, exhibiting dynamic cross market effects. Moreover, we emphasize the pertinence of conditional covariances and we show that volatility spillovers are time-varying and very responsive to the major economic events, increasing in periods of higher turbulence, which reinforces the importance of closely monitoring the evolution of money markets.

A Positive Model of Reserve Requirements and Interest on Reserves: A Clearinghouse Interpretation of the Federal Reserve System

This paper develops a positive model of reserve requirements and interest on reserves, based on the observation that Congress exempted the Fed from a legal restriction that had prevented private clearinghouses from issuing their own currency. Eliminating the restriction provided the Fed with a source of revenue that could be used to finance general government outlays and to pay implicit interest on reserves. The model implies that the government's financing requirements help explain reserve requirement movements and that interest rates on reserves vary with market loan rates. Cointegration, error-correction, and Granger-causality tests provide supporting evidence.     

货币供给、通货膨胀与产出波动的动态效应研究：1992—2013

本文基于包含随机波动率的时变参数向量自回归（SV—TVP—VAR）模型研究了货币供给冲击作用下我国货币政策传导的动态响应机制。实证结果表明：我国的货币传导机制具有明显的时变效应,SV—TVP—VAR模型能够很好的刻画货币传导机制中的时变特征。同时,货币政策传导机制中时变效应大于惯性效应。此外,我国的货币供给过程表现为逐渐增强的产出缺口驱动特征。进一步研究发现,增加货币供给量这种扩张性的货币政策在短期内具有真实效应,能够显著的影响实际利率和产出水平,然而从长期来看对实际利率和产出水平却缺乏永久性影响。     

Is there a direct effect of money?: Money’s role in an estimated monetary business cycle model of the Japanese economy

In this paper, to study the alternative monetary transmission mechanism to the traditional interest rate channel which may even work under zero nominal interest rates, we estimate the monetary business cycle model of the Japanese economy that incorporates the direct role of money. Estimation is conducted on the system of equations in a state-space form via maximum likelihood estimation. We, however, find that the direct effect of money is extremely small in Japan. This finding is the same as those obtained for the U.S. in Ireland [Ireland, P., 2004. Money’s role in the monetary business cycle. Journal of Money, Credit and Banking 36, 969–984] and the Euro area in Andres et al. [Andres, J., Lopez-Salido, D., Valles, J., 2001. Money in an Estimated Business Cycle Model of the Euro area. Working Paper 121, Bank of Spain].     

On the comparison of alternative specifications for money demand: The case of extremely low interest rate regimes in Japan

Using Japanese money market data, this paper compares the predictive ability of the log–log specification with infinite elasticity at a zero interest rate and the semilog specification with a one time switch from moderate to relatively high semielasticity at annual interest rates less than 0.5%. We find that the latter specification dominates the former in terms of predictive ability for the extremely low interest rate regime (the period between 1999 and 2006) because under the former the semielasticity is excessively sensitive to slight changes in interest rates. We find that interest rate semielasticity has remained stable at a high level since the mid-1990s.     

Dynamic panel cointegration approaches to the estimation of money demand functions

This paper investigates properties of the money demand functions of Group of Six (G6) member countries (Canada, France, Italy, Japan, U.K., and U.S.) using the estimation and inference techniques of panel cointegration. Empirical analyses are conducted by estimating money demand equations of G6 countries individually and as a whole, allowing heterogeneity in individual specific fixed effects across countries through dynamic, nonstationary panel estimation techniques. By using recently developed panel cointegration techniques, the paper contributes to the literature of money demand studies by improving the power performance of the relevant estimation and inference procedures. It reports fully modified OLS (FMOLS) estimation results of the money demand model for different data frequencies, to find varying signs and magnitudes of real income, interest rates and inflation elasticities of money demand for G6 nations.     

Innovations in return transmission and performance comparison between the five biggest Euro area stock markets

This article presents an empirical analysis of integration and performance of the five biggest stock markets of the Euro area: France, Germany, Holland, Italy and Spain. This empirical analysis begins with the estimation of an EMU market model with time-varying beta coefficients, which is the basis for the subsequent estimation of the transmission of innovations and volatility between those markets. The present article compares the performance of those stock markets measured by time-varying Treynor ratios. Those ratios support the creation of a portfolio which explores the performance differences between those markets. The capability of this portfolio to exploit those performance differences is subject to evaluation by comparison with a benchmark represented by an equally weighted portfolio.     

The identification of liquidity effects in the EMS: Italy 1991–1992

We study the impact of liquidity shocks in Italy in the 1991–1992 period, when the lira belonged to the narrow ERM band with no exchange controls. We conduct our analysis by constructing (not simply assuming) predetermined measures of liquidity supply shocks, taking into account the institutional features of the money market and the reserve requirements' average computation system. We find that the supply of liquidity did significantly affect short-term interest rates; however, in contrast to earlier periods, most of the interest rate variations were attributable to foreign-exchange-related factors, as predicted by the asymmetric view of the ERM.     

An Analysis of the Structure of Interest Rates in Taiwan: An Application of the Vector ARIMA Model

The structure of interest rates in Taiwan is analysed through the vector ARIMA approach using monthly and quarterly data from 1978 to 1989. These rates are the regulated bank interest rate and unregulated money market interest rates in the formal financial market and the kerb rate in the informal market. The results show that the adjustments in the bank interest rate follow that of the money market interest rate. Furthermore, the time lag has been shortened from one quarter in the early stages of interest rate liberalization in Taiwan to only one month in the later stages. Increases in the money market interest rate might be followed by an increase in the kerb market interest rate because of partial market segmentation. In periods when there is excess supply of funds in the banking sector, an increase in the bank rate might be followed by a decrease of the kerb rate. The interest rates structure of Taiwan is relevant to developing countries which have an informal financial sector.
