Optimal Exchange Intervention in an Inflation Targeting Regime: Some Cautionary Tales

Devaluations and fiscal retrenchments coming from developed countries are buffeting less developed countries. Many emerging market countries have adopted inflation targeting as “best practice,” but now they are being advised to enhance their inflation targeting regimes with foreign exchange intervention. Here we use a DSGE model to tell some cautionary tales about this advice. A Taylor rule guides interest rate setting, while foreign exchange interventions are used as a second tool of monetary policy. These interventions are effective in our model since domestic and key currency bonds are imperfect substitutes. We derive optimal (Ramsey) intervention policies in response to foreign devaluations and fiscal retrenchments, and find that they are rather complex. So, we compare the optimal responses to policies that simply smooth real or nominal exchange rate movements. Our results suggest that discretion may be the better part of valor: pure inflation targeting may come closer to the optimal policy than exchange rate smoothing. A secondary result may also be of some interest: foreign exchange interventions have a stronger impact on inflation and output in an inflation targeting regime than do sterilized interventions; the Taylor rule augments the effects of a given intervention.     

Monetary autonomy in selected Asian economies: The role of international reserves

With the increased financial integration of Asian countries, monetary policy takes on the additional role of maintaining the stability of the financial system along with the traditional objectives of promoting growth and employment with price stability. Given the importance and relevance of monetary policy in Asian countries, we examine monetary autonomy and its interaction with financial integration, currency regimes and international reserves for the past two decades in the following Asian countries: Thailand, Korea, Indonesia, the Philippines, and India. The empirical analysis reveals two significant and interesting findings that have policy implications. First, Thailand, Korea and Indonesia, countries that have moved towards a floating currency regime, experienced simultaneous declines in the sensitivity of their interest rates (thereby increasing monetary autonomy), while India continues to increase the sensitivity of its interest rates with a pegged exchange rate and increased financial integration. Second, in all of the studied economies, the accumulation of international reserves has contributed, to some extent, to the retention of monetary autonomy in terms of preventing the sensitivity of the interest rates from rising. We speculate that the accumulation of reserves plays the role of an anchor for monetary autonomy in emerging market economies facing a “fear of floating”.     

Assessing the performance of inflation targeting in East Asian economies

This paper examines the implementation and performance of inflation targeting (IT) in four East Asian emerging market economies: Indonesia, Korea, the Philippines, and Thailand. It also examines monetary policy in Malaysia, a country that has not adopted IT. The study estimates policy reaction functions to test the links between the adoption of IT and use of a monetary policy rule. The impulse responses of prices to a monetary policy shock are also estimated to identify monetary policy impacts on prices. The findings on the monetary policies of the five economies can be summarised as follows. Korea has taken an inflation‐responsive and forward‐looking policy stance under inflation targeting, which has had an effect on the stability of prices. Indonesia and Thailand have conducted inflation‐responsive but backward‐looking policy stances, which have had no impact in terms of price stabilisation. The Philippines (which adopted IT but under a pegged exchange rate regime) and Malaysia have neither followed inflation‐responsive rules nor had policy impacts in terms of controlling inflation.     

基于金融稳定目标的规则型货币政策研究

随着货币政策与金融稳定之间联系的不断深化，中央银行理应在防范金融市场系统性风险中发挥重要的作用。文章首先构建我国金融稳定指数，并将其加入线性货币政策规则，研究结果表明，中央银行在调整名义利率时的确对金融稳定状况有所关注，相比于传统泰勒规则，纳入金融稳定指数的泰勒规则中通胀系数与产出缺口系数均有显著改善，其能够更好地拟合中央银行的实际政策操作。随后，为了进一步考察货币当局对名义利率调整的动态变化特征，文章通过TVP-SV-VAR模型对拓展的时变参数泰勒规则进行了再估计。研究发现，随着经济周期和金融形势的更迭，中央银行也会不断动态调整其政策目标。其中，货币政策对通货膨胀的调控不存在明显的惰性区域，控制通胀始终是中央银行工作的重心。其次，中央银行存在规避经济收缩的偏好，在经济下行时期其对货币政策的调整会向产出缺口倾斜。最后，为了抑制金融机构的过度风险承担，货币当局在本次金融危机之后显著增强了对于金融稳定的关注。     

Testing the Taylor Model Predictability for Exchange Rates in Latin America

Exchange rates forecasting performance is tested by a model which incorporates endogenous monetary policy through a Taylor rule reaction function. Other usual monetary and equilibrium empirical exchange rate models are also evaluated for comparison purposes. Predictability is tested by comparing the models to a benchmark random walk specification. We contribute to the recent literature in many ways. First, we include models of forward-looking endogenous monetary policy to the exchange rate forecasting exercise, the Taylor model. Second, our data, set across countries, is uniform in terms of economies adopting both inflation targeting and a flexible exchange rate. Third, our study sheds light on exchange rate determinants for emerging economies: Brazil, Chile, Colombia, Peru and Mexico. Our results show strong predictability evidence for the Taylor model and indicate that assuming models of endogenous monetary policy and the present value of expected fundamentals is a rewarding strategy to model exchange rate determination.     

Reactions to Shocks and Monetary Policy Regimes: Inflation Targeting Versus Flexible Currency Board in Sub‐Saharan Africa

The paper examines the monetary policy actions through which central banks in sub‐Saharan Africa have tried to eliminate the negative impacts of the shocks facing their economies. We compare two different monetary policy regimes: a currency board regime (in the CFA zone) and an inflation targeting policy regime (Ghana and South Africa) when central banks respond to demand, supply, and fiscal shocks. We extend the usual forecasting and policy analysis system models to replicate the economic features of these economies during the period 2002–12 and to evaluate the impact of several policies in response to these shocks. We find that both policies are inappropriate in helping the economies escape from the effects of negative demand shocks, both are essential when negative shocks to primary balance occur, while inflation targeting dominates the currency board regime as a strategy to cope with positive shocks to inflation.     

Terms of Trade Shocks and Inflation Targeting in Emerging Market Economies

Emerging market economies (EMEs) have persistently experienced different waves of commodity terms of trade disturbances, generating macroeconomic instabilities. The adoption of inflation targeting (IT) by many EMEs has raised questions about its relative suitability in dealing with these shocks compared with other monetary policy regimes. This paper tests the robustness of IT compared with monetary targeting and exchange rate targeting regimes in coping with commodity terms of trade shocks using the panel vector autoregressive technique. The results show that in general, IT countries respond better to commodity terms of trade shocks especially with respect to inflation and output gap. However, exchange rates are more volatile in IT countries than in exchange rate targeting countries. The results suggest that EME countries can reduce the adverse effects of commodity terms of trade fluctuations when they adopt IT, but they also need to pay attention to exchange rate movements.     

The Optimal Monetary and Macroprudential Policies for the South African Economy

We investigate the optimal design and effectiveness of monetary and macroprudential policies in promoting macroeconomic (price) and financial stability for the South African economy. We develop a New Keynesian dynamic stochastic general equilibrium model featuring a housing market, a banking sector and the role of macroprudential and monetary policies. Based on the parameter estimates from the estimation, we conduct an optimal rule analysis and an efficient policy frontier analysis, and compare the dynamics of the model under different policy regimes. We find that a policy regime that combines a standard monetary policy rule and a macroprudential policy rule delivers a more stable economic system with price and financial stability. A policy regime that combines an augmented monetary policy (policy rate reacts to financial conditions) with macroprudential policy is better at attenuating the effects of financial shocks, but at a much higher cost of price instability. Our findings suggest that monetary policy should focus solely on its primary objective of price stability and let macroprudential policy facilitate financial stability on its own.     

Commodity Prices, Inflationary Pressures, and Monetary Policy: Evidence from BRICS Economies

We assess the transmission of monetary policy and the impact of fluctuations in commodity prices on the real economy for the five biggest and fastest growing emerging market economies: Brazil, Russia, India, China and South Africa (BRICS). Using modern econometric techniques, we show that a monetary policy contraction has a negative effect on output, suggesting that it can lean against unexpected macroeconomic shocks even when the financial markets are not well-developed in this group of countries. We also uncover the importance of commodity price shocks, which lead to a rise in inflation and demand an aggressive behaviour from central banks towards inflation stabilisation.     

Commodity prices and monetary policy in emerging East Asia during the global financial crisis

In the first phase of the global financial crisis, rising inflation was a major concern for emerging East Asian central banks. Coupled with a slowing US economy, regional central banks faced a monetary policy dilemma of either addressing higher inflation or supporting moderate growth. Higher food and fuel prices were the major drivers of headline inflation. Their causes, however, were a confluence of mutually reinforcing cyclical and structural factors. Understandably, different economies faced a different balance of risks between price stability and growth; but to attribute the inflation to supply shocks alone was misleading. This was unsettling given that inflation and inflation expectations were on the rise, and without much credibility, the reluctance of many central banks to raise interest rates risked repeating the mistake the advanced economies made in the 1970s. Without credibility, inflation expectations are unlikely to be well anchored. To gain credibility, a central bank must ‘walk‐the‐talk’, and understandably it must have the autonomy to do so.     

What to Aim for? The Choice of an Inflation Objective when Openness Matters

Inflation targeting countries generally define the inflation objective in terms of the consumer price index. Studies in the academic literature, however, reach conflicting conclusions concerning which measure of inflation a central bank should target in a small open economy. This paper examines the properties of domestic, CPI, and real-exchange-rate-adjusted (REX) inflation targeting. In one class of open economy New Keynesian models there is an isomorphism between optimal policy in an open versus closed economy. In the type of model we consider, where the real exchange rate appears in the Phillips curve, this isomorphism breaks down; openness matters. REX inflation targeting restores the isomorphism but this may not be desirable. Instead, under domestic and CPI inflation targeting the exchange rate channel can be exploited to enhance the effects of monetary policy. Our results indicate that CPI inflation targeting delivers price stability across the three inflation objectives and will be desirable to a central bank with a high aversion to inflation instability. CPI inflation targeting also does a better job of stabilizing the real exchange rate and interest rate which is an advantage from the standpoint of financial stability. REX inflation targeting does well in achieving output stability and has an advantage if demand shocks are predominant. In general, the choice of the inflation objective affects the trade-offs between policy goals and thus policy choices and outcomes.     

CAN TUNISIA MOVE TO INFLATION TARGETING?

Inflation targeting has become an alternative monetary strategy that has been followed by many industrial and emerging countries. This study considers whether the adoption of inflation targeting would be relevant for Tunisia. More specifically, this paper aims at checking whether the necessary conditions for the successful implementation of such a strategy are fulfilled or not. It is found that fiscal dominance does not constitute the main hindrance to the adoption of inflation targeting. Other impediments have been identified, especially a weak financial system in general, the unsound and fragile banking system in particular, and the glaring lack of knowledge about the monetary transmission mechanism. Furthermore, it has been pointed out that if Tunisian monetary authorities continue to carry out the present exchange rate regime, namely, the constant real exchange rate rule, an inflation targeting regime will not be sufficient to properly contain the inflation pressures caused by demand shocks.     

Price and Output Stability under Price-Level Targeting

It is commonly believed that a monetary policy that targets the price level reduces the long-term variability of the price level, but only at the cost of increased variability of both inflation and output. We develop a model in which the one-step-ahead variance of output and the price level are lower under price-level targeting than under inflation targeting. This increased stability under price-level targeting works through an interest-rate channel that, to our knowledge, has not previously been emphasized in the literature. Surprisingly, if the sensitivity of demand to the real rate of interest is high enough, then the variance of inflation can also be lower under price-level targeting than under inflation targeting.     

What Causes China＇s High Inflation？ A Threshold Structural Vector Autoregression Analysis

China＇s astonishing economic growth implies a necessity to understand its inflation. The present paper employs threshold nonrecursive structural vector autoregression analysis to explore the asymmetric effects of macro-variables on inflation in low and high inflation regimes. The empirical evidence demonstrates, first, that the reactions of inflation to various shocks are inflation-regime-dependent and asymmetric. Second, monetary policy influences China ＂s high inflation and adjusting the domestic interest rate in China may be an effective way to control inflation in a high inflation regime, but not in a low inflation regime. In a high inflation regime, a high inflation rate may cause the macro-policy authorities to increase the domestic interest rate, in an attempt to stabilize high inflation. Third, contrary to expectations, the world oil price is not a strong cost-push factor in a low inflation regime. Oil price increases may increase inflation in a high inflation regime, but there is no such obvious effect in a low inflation regime. Finally, China ＂s nominal effective exchange rate influences inflation in both low and high inflation regimes. A nominal effeetive exchange rate appreciation might be effective in controlling domestic inflation in both regimes.     

Surfing the waves of globalization: Asia and financial globalization in the context of the trilemma

Using the “trilemma indexes” developed by Aizenman et al. (2010) that measure the extent of achievement in each of the three policy goals in the trilemma—monetary independence, exchange rate stability, and financial openness—we examine how policy configurations affect macroeconomic performances, with focus on the Asian economies. We find that the three policy choices matter for output volatility and the medium-term level of inflation. Greater monetary independence is associated with lower output volatility while greater exchange rate stability implies greater output volatility, which can be mitigated if a country holds international reserves (IR) at a level higher than a threshold (about 20% of GDP). Greater monetary autonomy is associated with a higher level of inflation while greater exchange rate stability and greater financial openness could lower the inflation rate. We find that trilemma policy configurations affect output volatility through the investment or trade channel depending on the openness of the economies. Our results indicate that policy makers in a more open economy would prefer pursuing greater exchange rate stability while holding a massive amount of IR. Asian emerging market economies are found to be equipped with macroeconomic policy configurations that help the economies to dampen the volatility of the real exchange rate. These economies’ sizeable amount of IR holding appears to enhance the stabilizing effect of the trilemma policy choices, and this may help explain the recent phenomenal buildup of IR in the region.     

The Yield Curve as a Predictor and Emerging Economies

This paper tests whether the slope of the yield curve in emerging economies predicts inflation and growth. It also investigates whether the USA and euro area curves help to predict. It finds that the yield curve in emerging economies contains information for future inflation and growth, with differences across countries being seemingly linked to market liquidity. The US and euro area yield curves are also found to contain information for future inflation and growth in emerging economies. In particular, for those economies with exchange rates pegged to the US dollar, the US yield curve is often a better predictor than the domestic curves and causes their movements. This suggests that monetary policy changes in the USA are drivers of international financial linkages through base interest pass-through and the low end of the yield curve.     

美国现行宽松货币政策对世界物价的影响——基于不同经济体通货膨胀表现的分析

美国2007年年底开始大幅下调利率,2009年以来又采取了量化宽松的货币政策。与此同时,世界各国,尤其是新兴市场和发展中经济体发生了严重的通货膨胀。虽然美国的宽松货币政策确实提高了2008年以来的通货膨胀率,但是却不能解释新兴市场和发展中经济的通货膨胀普遍高于发达经济体的事实。高通胀的原因仍然在于各国国内的高货币供给。     

Money and price relationship in China

This paper investigates the effectiveness monetary policy by Granger causality tests in the two regimes of inflation and deflation, respectively. The surplus lag rolling estimation is applied to deal with the problem of the frequent structural changes in the Chinese monetary system. We found that the monetary policies have become less effective in stabilizing the price level in the deflation era that started from 1998. There is also empirical evidence to suggest that money was endogenous in China during the inflation period. This implies that the People's Bank of China had difficulty exercising the power of money supply to reduce inflation if the endogeneity was the result of the market behaviour. However, if the endogeneity was due to the government inflation-targeting rule, then there is no evidence to suggest that this rule has been effective for M0, M1 and M2 instruments, except for the M0 instrument during the inflation period of April 1990 to March 1995. Although it was found that money ceased to be endogenous in the deflation periods, it does not support the proposal of utilizing the money supply as a policy instrument, as we found that money is impotent in influencing price in the deflation regime. Our findings provide some empirical evidence to support the Chinese government adopting alternative policy instruments such as an active fiscal policy in the era of deflation.     

Monetary analysis and the global financial cycle: An Asian central bank perspective

Emerging Asia has seen a transformation of its monetary policy environment over the past two decades. By far, the most relevant change has been the maturing of its financial systems and the growing relevance of the global financial cycle: financial inclusion has spread, financial markets have deepened and financial globalisation has linked domestic markets closer to international markets. One consequence of the maturing of the financial systems has been the weakening of the traditional case for the monetarist view of the roles of monetary aggregates in the conduct of monetary policy. In addition, the maturing of the financial systems has elevated concerns of financial stability, as both a source of shocks and a responsibility of central banks. These developments have been further complicated by monetary policy spillovers from the advanced economies. All this points to the need to consider alternatives to conventional inflation targeting frameworks. This paper lays out a policy framework based on a multi-pillar monetary policy approach as a potentially attractive alternative for EM Asia. The three pillars are based on economic, financial and exchange rate stability, respectively. This framework not only offers an alternative conceptual framework but also implies institutional reforms to ensure central banks take a longer term perspective when setting policy.     

Inflation targeting in India: A comparison with the multiple indicator approach

The empirical literature on identification and measurement of the impact of monetary policy shocks on the real side of the economy is fairly comprehensive for developed economies, but very limited for emerging and transition economies. In this study, we propose an identification scheme for a developing economy (taking India as a case study), which is able to capture the monetary transmission mechanism for that economy without giving rise to empirical anomalies. Using a VAR approach with recursive contemporaneous restrictions, we identify monetary policy shocks by modelling the reaction function of the central bank and structure of that economy. The effect of monetary policy shocks on the exchange rate and other macroeconomic variables is consistent with the predictions of a broad set of theoretical models. This set-up is used to build a hypothetical case of inflation targeting where the monetary policy instrument is set after assessing the current values of inflation only. This is in contrast with the ‘multiple indicator approach’ currently followed by the Reserve Bank of India (RBI). The results in this study suggest that the demand effects of interest rate are stronger than the exchange rate effects. There is also evidence of the mitigation of potential conflict between exchange rate and interest rate, one of main monetary policy dilemmas of the RBI in inflation targeting.
