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.     

Monetary policy,exchange rate targeting and fear of floating in emerging market economies

This paper investigates whether central banks in emerging markets systematically respond to exchange rate movements. It estimates a structural general equilibrium model of a small open economy with an exchange rate-augmented Taylor-type rule for four countries. The results show that over the entire sample-period, South Africa and Mexico do not target the exchange rate, whereas Indonesia and Thailand do. In the 1980s and 1990s, all four countries targeted the exchange rate but in the aftermath of the Asian financial crisis, the Mexican peso crisis, and the end of apartheid, they all liberalized their exchange rate regimes, shifting toward inflation targeting.     

What Drives Monetary Policy in Post-Crisis East Asia? Interest Rate or Exchange Rate Monetary Policy Rules

This paper estimates a simple small open macroeconomic model to analyse the effectiveness of monetary policy rules (MPRs) where either the nominal interest rate or the nominal exchange rate is the policy instrument. The aim is to ascertain which of those MPRs are best suited for a selection of inflation targeting economies of Asia. Normally, one would associate inflation targeting with interest rate rules but it is thought that, due to fear of floating, exchange rate rules may well be more effective given the openness of these economies. It is found that interest rate rules seem to better reflect the prevailing policy regime than exchange rate rules. It is also found that stronger relationships pertaining to the interest rate rules are found in the case of Korea and Thailand than for Indonesia and the Philippines. Exchange rates appear to be very influential in determining the value of the nominal interest rate but not in a policy sense.     

经济周期波动中的东南亚利率政策

2008年的全球性金融危机对东南亚消费、投资和出口形成冲击,东南亚经济渐入萧条通道,印尼、马来西亚、菲律宾、泰国先后推出经济刺激计划,实施降低利率的扩张性货币政策。2010年之后,东南亚经济复苏之势明显,但复苏的持续性受对外出口、政府需求可替代性因素的影响,东南亚连续加息旨在抑制物价上涨,防止低利率可能引发的经济泡沫化。     

Optimal Monetary Policy Rules and Inflation Targets: Are Australia,Canada, and New Zealand Different from the U.S.?

Outwardly, the central banks of Australia, Canada, New Zealand, and the U.S. follow somewhat different approaches to controlling inflation. The U.S. does not explicitly target inflation while the other countries do. Canada and New Zealand have target bands for inflation while Australia has a point target. Results in this paper nevertheless find broad similarities in the monetary policies of these countries. Each can be described as having pursued optimal inflation targeting (explicit or implicit), with heavy interest rate smoothing, but perhaps placing little weight on output variability. We argue that interest rate smoothing is used to introduce gradualism into the response of monetary policy to inflation. We show that given heavy interest rate smoothing, a concern for output variability is redundant.     

Monetary policy shocks and exchange rates in Asian countries

In this paper, we empirically investigate the effects of monetary policy shocks on exchange rates in Asian countries. To do so, we use VAR models which impose sign restrictions on impulse responses to identify monetary policy shocks. We find that contractionary monetary policy shocks lead to significant exchange rate appreciation in Malaysia, the People’s Republic of China, and the Republic of Korea. However, in India, Indonesia, the Philippines and Thailand, we find either a significant depreciation or no significant effect. These results suggest that an interest rate increase (or decrease) may not necessarily shield Asian countries from exchange rate depreciation (or appreciation) pressure following a U.S. interest rate increase (or decrease).     

Does Money Have a Role in Monetary Policy for Price Stability under Inflation Targeting in Thailand?

This paper deploys Thai quarterly data for the study period 1999q1–2014q4 to econometrically investigate the proposition that money growth is an important, if not the sole, determinant of inflation under inflation targeting and that the money growth-inflation relation is not conditional on the stability of the money-demand function. The autoregressive distributed-lag (ARDL) bounds-testing results suggest that, across the study period, the Thai money stock (narrow or broad), real output, prices, interest rates and exchange rates maintained a long-run equilibrium relationship. The associated error-correction model of inflation confirms the cointegral relationship among money (narrow or broad), real output, prices, interest rates and exchange rates. It also suggests that money growth has a significant distributed-lag impact on inflation. The presence of this money growth-inflation relationship was associated with a stable narrow money-demand function, whereas the broad money-demand function remained unstable. These results for the study period are consistent with the view that the causal relationship between money growth and inflation holds in Thailand under inflation targeting when the Bank of Thailand deploys a short-term policy interest rate, rather than a monetary aggregate, as the instrument of monetary policy and that this relationship is not conditional on the stability of the money-demand function.     

Is monetary policy non‐linear in Indonesia,Korea, Malaysia,and Thailand? A quantile regression analysis

There is a growing literature on the linearity or otherwise of monetary policy in industrialised countries. The investigations have revealed that the reactions of central banks to economic variables depend on the level of the variables, confirming the non‐linearity of monetary policy in these countries. However, research into whether monetary policy is non‐linear in emerging markets has been hampered by the lack of data, as a stable, ‘modern’ monetary regime has existed in emerging markets for only a relatively short time. Employing quantile regression, which is not as constrained as other regression methods by the shortness of time series, we investigate the non‐linearity of monetary policy in four emerging Asian nations: Indonesia, Korea, Malaysia, and Thailand. Our results indicate that monetary policy in all four is non‐linear. All display a ‘hump‐shaped’ response to inflation across the quantiles—policy becomes tighter, going from lower to higher quantiles, reaches a peak, and then becomes looser. These results are similar to those found previously in Japan, and likely arise from a desire to limit exchange rate appreciation, as all four countries depend heavily on exports.     

Monetary Aggregates Targeting,Inflation Targeting and Inflation Stabilization in Ghana

The central bank of Ghana (BoG) has operated monetary aggregates targeting and inflation targeting since the 1980s, to ensure enhanced output growth, low unemployment and stable, low inflation. Under inflation targeting, the inflation rate averaged 13.26 per cent per annum between 2007 and 2015, compared with 29.22 per cent per annum under monetary aggregates targeting. The relatively lower inflation rates notwithstanding, an average inflation rate of 13.2 per cent per annum is far above the medium‐term target of 8 per cent. This paper has examined the effectiveness of monetary aggregates targeting and inflation targeting in keeping inflation at moderate levels. The autoregressive distributed lag (ARDL) model was applied to the data covering the period 1970–2015. The results show that monetary targeting has steered inflation to moderate levels only in the short run while inflation targeting has maintained low inflation rates in both short run and long run. But neither regime has kept inflation at stable levels and within the target band, due to the sluggish transmission of broad money supply and prime rate changes to inflation. We implore the monetary authorities to strengthen the institutional setup for steering short‐term interest rates in Ghana. They should also enhance the BoG Act 2002 (Act 612), to develop secondary anchors and rules around output, money supply and fiscal deficit. Finally, the monetary policy committee should monetary policy credibility and transparency through strengthening its communication framework.     

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.     

Inflation Targeting in ASEAN‐10

The paper addresses the empirical question of whether economies that do not systematically target inflation (non‐inflation targeters) experience higher exchange rate volatility as compared with inflation targeters in 10 countries of the Association of Southeast Asian Nation (ASEAN) from 1990 to 2010. The paper examines the role of real exchange rate, exchange rate volatility and the reaction functions of central banks using dynamic panel estimation techniques. The results indicate that the output gap offers more useful information than the inflation gap in setting interest rates for inflation targeters, implying that the real term is more important than the nominal term. In turn, this suggests that an increase in interest rate can be wielded swiftly to reduce real gross domestic product and suppress inflation. The real exchange rate appears as a weaker determinant in setting interest rates for non‐inflation targeters. Inflation targeters experienced lower exchange rate volatility compared with non‐targeters in the ASEAN, which implies that implementation costs to their domestic economies may be marginally lower. Meanwhile, the non‐targeters follow a mixed strategy as both the inflation and real exchange rate are used as instruments to set the interest rates.     

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.     

Exchange rates,price levels,and inflation targeting: Evidence from Asian countries

This study examines how the adoption of inflation-targeting influenced exchange rate pass-through and volatility in four Asian countries –Indonesia, South Korea, the Philippines, and Thailand – over the sample period of January 1990 to June 2007. We find that adopting inflation targeting helped reduce pass-through in South Korea, and Thailand, while the results are less clear for Indonesia and the Philippines. Nevertheless, the findings indicate that inflation targeting caused a decline in exchange rate volatility in all four countries. The important lesson from the experiences of these Asian countries is that the adoption of inflation targeting contributes to achieving the ultimate goal of inflation stability through reducing exchange rate pass-through or variability.     

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.     

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.     

Towards improved monetary policy in Indonesia

Indonesia's depreciation vastly exceeded that of all other countries hit by the Asian crisis. Indonesia also experienced far higher inflation. This paper argues that there is a close medium to long-term relationship between money growth and inflation in Indonesia, and that this has not been greatly disturbed by the crisis. It argues that the country's disappointing performance in relation to maintaining the value of the rupiah can be explained by the central bank's failure to sterilise the monetary impact on base money of its last-resort lending to the banks. The fundamental lesson is that Bank Indonesia would be well advised to adopt slow and steady growth of base money as the nominal anchor for monetary policy, now that the pre-crisis policy of slow and steady depreciation of the rupiah has been abandoned.     

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.     

COPING WITH INFLATION AND EXCHANGE RATE SHOCKS IN THE SOUTH AFRICAN ECONOMY

Over the past ten years South Africa has moved to an increasingly open economy, characterised by a (relatively) low inflation and large and unpredictable movements in the prices of financial assets. One of these asset prices is the value of the South African currency. This volatility in the exchange rate has a direct impact on inflation. Using the interest rate as operational target, a central bank might ignore or underestimate the exchange rate transmission mechanism through which the economy is influenced. This paper proposes a Monetary Conditions Index for South Africa that can be used as a policy rule or simply as an important information variable in conducting monetary policy under an inflation‐targeting regime with a volatile exchange rate.

Currency Substitution and the Stability of the Demand for Money in East Asia

Abstract

This paper models and tests the stability of the demand for money in five East Asian countries—Indonesia, Malaysia, Philippines, Singapore, and Thailand—in the context of an open economy. The Johansen multivariate cointegration vector error correction analysis against quarterly data covering the period 1985:1–2001:4 was used. It was found that a stationary long run cointegrating relationship exists between broad money, real income, domestic interest rates, foreign interest rates corrected for exchange rate depreciation, and the expected rate of depreciation of the exchange rate. The results show that US Treasury bills rates and the foreign exchange rate vis-à-vis the US dollar play a significant role in the East Asian countries money demand relationship. This suggests that currency substitution vis-à-vis the US dollar may be an important consideration in the design and implementation of monetary policy in the East Asian countries. Furthermore, the results show that the Asian currency crises impacted the money demand functions negatively in these countries. CUSUM and CUSUMSQ stability tests show no evidence of parameter instability of the money demand functions in three of the five countries throughout the period under investigation.
