The East Asian Dollar Standard, Fear of Floating, and Original Sin

Before the crisis of 1997/98, the East Asian economies—except for Japan but including China—pegged their currencies to the US dollar. To avoid further turmoil, the IMF argues that these currencies should float more freely. However, the authors’ econometric estimations show that the dollar's predominant weight in East Asian currency baskets has returned to its pre‐crisis levels. By 2002, the day‐to‐day volatility of each country's exchange rate against the dollar had again become negligible. Most governments were rapidly accumulating a “war chest” of official dollar reserves, which portends that this exchange rate stabilization will come to extend over months or quarters. From the doctrine of “original sin” applied to emerging‐market economies, the authors argue that this fear of floating is entirely rational from the perspective of each individual country. And their joint pegging to the dollar benefits the East Asian dollar bloc as a whole, although Japan remains an important outlier.     

One money, one market: the effect of common currencies on trade

A gravity model is used to assess the separate effects of exchange rate volatility and currency unions on international trade. The panel data, bilateral observations for five years during 1970–90 covering 186 countries, includes 300+ observations in which both countries use the same currency. I find a large positive effect of a currency union on international trade, and a small negative effect of exchange rate volatility, even after controlling for a host of features, including the endogenous nature of the exchange rate regime. These effects, statistically significant, imply that two countries sharing the same currency trade three times as much as they would with different currencies. Currency unions like the European EMU may thus lead to a large increase in international trade, with all that that entails.

Monetary Policy in the Aftermath of Currency Crises: The Case of Asia

The paper evaluates monetary policy and its relationship with the exchange rate in the five Asian crisis countries. The findings are compared with previous currency crises in recent history. It is found that there is no evidence of overly tight monetary policy in the Asian crisis countries in 1997 and early 1998. There is also no evidence that high interest rates led to weaker exchange rates. The usual tradeoff between inflation and output when raising interest rates suggested the need for a softer monetary policy in the crisis countries to combat recession. However, in some countries, corporate balance sheet considerations suggested the need to reverse overly depreciated currencies through firmer monetary policy.     

The purchasing power parity of Southeast Asian currencies: A time-varying coefficient approach

The economies of Southeast Asia have undergone several structural changes, including the Asian currency crisis, during the post-Bretton Woods era. We use a time-varying coefficient cointegration model to test for purchasing power parity (PPP) of Southeast Asian currencies and to track changes in purchasing power relationships over time. The main empirical findings are as follows. First, the stability of the relationship between exchange rates and price differentials is strongly rejected. Second, a major structural change occurs at the outbreak of the Asian currency crisis in 1997. Third, when the cointegration vector is allowed to vary with time, we find evidence of a cointegration relationship for four countries in terms of the US dollar and for four countries in terms of the Japanese yen. Therefore, it seems unlikely that Southeast Asian currencies form a “yen bloc.”     

Currency Areas and International Monetary Reform at the Dawn of a New Century

The Asian crisis and the creation of the euro have jump-started once again discussion of exchange rate systems, currency areas, and international monetary reform. The role of power in the international monetary system is discussed and its relevance to analysis of the new euro area as an instigator of change in the power configuration of the system. The dollar, euro, and yen areas have achieved a high degree of price stability, but international efficiency is seriously undermined by exchange rate gyrations of these three currencies. The best path to international monetary reform leads through a new international currency called the INTOR based on a G-3 monetary union platform possibly linked to gold.     

Is East Asia an optimum currency area?

This paper assesses the empirical desirability of the East Asian economies to an alternative exchange rate arrangement (a monetary union) that can potentially enhance the exchange rate stability and credibility in the region. Specifically, the symmetry in macroeconomic disturbances of the East Asian economies is examined as satisfying one of the preconditions for forming an Optimum Currency Area (OCA). We extend the existing literature by improving the methodology of assessing the symmetry shocks in evaluating the suitability of a common currency area in the East Asian economies employing the Bayesian State-Space Based approach. We consider a model of an economy in which the output is influenced by global, regional and country-specific shocks. The importance of a common regional shock would provide a case for a regional common currency. This model allows us to examine regional and country-specific cycles simultaneously with the world business cycle. The importance of the shocks decomposition is that studying a subset of countries can lead one to believe that observed co-movement is particular to that subset of countries when it in fact is common to a much larger group of countries. In addition, the understanding of the sources of international economic fluctuations is important for making policy decisions. The falling share of country specific factor and the rising role of region factor indicate that East Asia has become increasingly favorable for a monetary union. However, the share of country-specific factor that is still significant implies that it could be costly to renounce individual currencies to advance into a monetary union in East Asia.     

MACROECONOMIC VOLATILITY AND COUNTERFACTUAL INFLATION‐TARGETING IN HONG KONG

The present paper evaluates macroeconomic adjustment in Hong Kong with an estimated dynamic stochastic general equilibrium (DSGE) model under a fixed exchange rate regime. We find that exports and world inflation shocks are the dominant sources of GDP volatility, with the risk premium taking on importance during the Asian crisis after 1997. A counterfactual simulation, assuming a flexible exchange rate regime with inflation targeting, shows that inflation would have decreased slightly, but interest‐rate volatility would have increased significantly. The welfare gains from switching out of the currency board system appear to be marginal.     

The Vulnerability of ASEAN+3 Countries to International Financial Crises

This article focuses on the reaction of the Association of Southeast Asian Nations (ASEAN) economies to international financial shocks. The crises in emerging markets at the end of the last century underlined the significant vulnerability of the emerging ASEAN economies to international financial fluctuations and a lack of sustainability in their exchange rate regime. A structural VAR model is used to analyze the efficiency of the measures adopted by these countries after this episode of crisis in order to protect their economies against speculative attacks. The results reveal that the impact of the recent subprime crisis on emerging ASEAN countries is less significant than that observed in industrialized ones.     

Changing patterns of Asian currencies’ co-movement with the US dollar and the Chinese renminbi: Evidence from a wavelet multiresolution analysis

We extend the Frankel–Wei approach by using wavelet analysis to evaluate the relative importance of the dollar and the renminbi as anchor currencies at different time scales. We find that Asian currencies’ co-movement with the dollar weakened after the global financial crisis, while that with the renminbi strengthened particularly after China introduced a new exchange rate management system in 2015. The evidence suggests that emerging Asian economies have recently attached more importance to the renminbi as an anchor in exchange rate management.     

亚洲金融危机后亚洲各国汇市的波动特征改变了吗

亚洲金融危机首先爆发在各国的汇市上。危机过后多年,亚洲汇市的波动与危机前的状况有实质性改变吗?本文运用GARCH模型比较了亚洲各国及地区(韩国、泰国、台湾地区、新加坡、日本、印度、马来西亚和中国)汇市波动变化并进行了排序。实证结果表明,亚洲危机后各国汇市波动的方差扩大,冲击的影响在汇市上持续时间也有所延长。其原因是亚洲各国汇市的联动增加了。为了确保在第三国市场的份额,各国都在频繁调整和干预本国汇市。     

An Intertemporal Currency Board

The paper shows that the traditional wisdom of raising interest rates to defend a currency enriches rather than punishes the speculators. Furthermore, using high interest rates as a currency defense tool often produces the opposite effect in times of crisis. A new approach is proposed of using Hong Kong dollar "put" options as an explicit commitment by the government. The put option itself acts like an intertemporal currency board in keeping the linked exchange rate over time. This costly signaling produces a separating equilibrium that distinguishes the strength of the Hong Kong dollar from the other Asian currencies that were under pressure in 1997.     

The endogeneity of the Optimum Currency Area criteria in East Asia

The Asian financial crisis in mid-1997 has increased interest in policies to achieve greater regional exchange rate stability in East Asia. It has renewed calls for greater monetary and exchange rate cooperation. A country's suitability to join a monetary union depends, inter alia, on the trade intensity and the business cycle synchronization with other potential members of the monetary union. However, these two Optimum Currency Area criteria are endogenous. Theoretically, the effect of increased trade integration (after the elimination of exchange fluctuations among the countries in the region) on the business cycle synchronization is ambiguous. Reduction in trade barriers can potentially increase industrial specialization by country and therefore resulting in more asymmetry business cycles from industry-specific shocks. On the other hand, increased trade integration may result in more highly correlated business cycles due to common demand shocks or intra-industry trade. If the second hypothesis is empirically verified, policy makers have little to worry about the region being unsynchronized in their business cycles as the business cycles will become more synchronized after the monetary union is formed. This paper assesses the dynamic relationships between trade, finance, specialization and business cycle synchronization for East Asian economies using a Generalized Method of Moments (GMM) approach. The dynamic panel approach improves on previous efforts to examine the business cycle correlations — trade link using panel procedures, which control for the potential endogeneity of all explanatory variables. Based on the findings on how trade, finance and sectoral specialization have effects on the size of common shocks among countries, potential policies that can help East Asian countries move closer toward a regional currency arrangement can be suggested. The empirical results of this study suggest that there exists scope for East Asia to form a monetary union.     

On the Exchange Rate as a Nominal Anchor: The Rise and Fall of the Credibility Hypothesis

The credibility hypothesis, which was used to support the use of a pegged exchange rate arrangement as a nominal anchor mechanism, is based on restrictive analytical foundations that circumscribe its real world applicability. While all pegged exchange rate arrangements are subject to circumstances that can undermine the sustainability of the peg, exchange rate nominal anchor pegs are especially fragile because such arrangements introduce problems that are endogenous to that particular type of regime. The East Asian crisis is used to demonstrate the fragility of exchange rate nominal anchor pegs, while the case of Australia demonstrates how a floating currency escaped the contagion of the East Asian crisis.     

Non‐linear effect of exchange rate volatility on exports: the role of financial sector development in emerging East Asian economies

This paper empirically examines the role of financial sector development in influencing the impact of exchange rate volatility on the exports of five emerging East Asian countries – China, Indonesia, Malaysia, the Philippines and Thailand – using a GMM‐IV estimation method. The results indicate that the effect of exchange rate volatility on exports is conditional on the level of financial sector development. The less financially developed an economy, the more its exports are adversely affected by exchange rate volatility. In addition, a stable exchange rate seems to be a necessary condition to achieve export promotion via a currency depreciation in these economies.     

Currency Invoicing in International Trade: an Empirical Investigation

The authors investigate the choice of currency of invoicing in international trade under exchange rate fluctuations. Predictions derived from a model developed by Donnenfeld and Zilcha in 1991, and others, regarding the optimal choice of currency of invoice are tested for imports into Canada. The authors employ a unique dataset from Customs Canada that covers a six-year period and lists all currencies used for invoicing by industry. The empirical results support the hypothesis that there is a positive relationship between the extent of invoicing in the importer's national currency and exchange rate risk, and a negative relationship between invoicing in the exporter's currency as well as invoicing in a third currency and exchange rate risk. The empirical results further indicate that relative size of a country plays a role in determining the currency of invoicing.     

Analyzing exchange rate uncertainty and bilateral export growth in China: A multivariate GARCH-based approach

Dramatic changes to exchange rate policy for the world's largest exporter have arguably ushered in the optimal environment for studying the effects of exchange rate uncertainty on trade. This study builds on the recent literature by using an extremely general model that measures volatility using the flexible multivariate DCC-GARCH model to analyze the impact exchange rate uncertainty has on bilateral export growth for China's ten largest export markets. All model parameters are estimated simultaneously and lagged values of uncertainty are included for a full year, where significant effects are found. The more general methods potentially overcome issues associated with inefficient two-step methods and the assumption that volatility impacts are close to instantaneous. Using a comprehensive sample that spans 1994–2017, the paper presents evidence that exchange rate uncertainty has no impact on trade with the United States, which strongly contrasts a robust finding of trade deterring impacts for almost all remaining countries. The unifying methodology is also used to analyze nominal uncertainty itself. Here, it is found that Chinese inflation may be a positive contributor to risk in an environment where many exogenous events, such as the Asian currency crisis, are associated with periods of heightened yuan uncertainty.     

TOWARD A REGIONAL EXCHANGE RATE REGIME IN EAST ASIA

Abstract.  Deepening market-driven economic integration in East Asia makes intraregional exchange rate across the region increasingly desirable and necessary. The paper suggests that East Asia's emerging economies begin to choose a currency basket as a monetary policy anchor to enable all East Asian currencies to collectively appreciate vis-à-vis the US dollar, while maintaining intraregional rate stability, in the event of surges of capital inflows or a rapid unwinding of global payments imbalances. Following this initial step, East Asia may agree on more rigid intraregional exchange rate stabilization schemes through, for example, an Asian Snake or an Asian Exchange Rate Mechanism.     

Pegging emerging currencies in the face of dollar swings

The aim of this article is to study ruptures of exchange rate pegs by focusing on the fluctuations of the anchor currency. We test for the hypothesis that currencies linked to the USD are more likely to loosen their peg when the USD is appreciating, while sticking to it otherwise. To this end, we estimate smooth-transition regression models for a sample of 28 emerging currencies over the 1994–2011 period. Our findings show that while the real effective exchange rates of most of these countries tend to co-move with that of the USD in times of depreciation, this relationship is frequently reversed when the US currency appreciates over a certain threshold.     

THE EAST ASIAN CURRENCY CRISIS: CAUSES AND LESSONS

Financial deregulation and capital-account liberalization preceded speculative currency attacks in Thailand. A combination of de facto fixed exchange rates and high rates of interest generated excessive capital inflows, which led to too much liquidity chasing bad investments. The under-supervised and over-guaranteed financial sector extended loans excessively, particularly for non-productive, speculative purposes. Non-transparent practices, in the form of weak disclosure of institutions' true balance sheets and insider relations, masked these poor investments. The buildup of short-term, unhedged debt left East Asian economies vulnerable to a sudden collapse of confidence. Currency attacks ran down official foreign exchange reserves. Rapid capital outflows and the consequent depreciation of currencies exacerbated the strains on private sector balance sheets. The policy lessons are to (i) use macroeconomic policy to avoid excessive capital inflows and currency overvaluation, (ii) strengthen the financial system, with proper disclosure and accounting requirements, stringent loan classification and provisioning rules, and capital adequacy requirements, prior to capital-account liberalization, (iii) stabilize exchange rates based on currency baskets that reflect trade and investment linkages, and (iv) develop regional. financial cooperation with regional surveillance and peer pressure to maintain policy discipline.
