Should East Asia’s currencies be pegged to the yen? The role of invoice currency

Growing concern that a dollar peg exposes East Asian economies to fluctuations in the dollar–yen exchange rate has stimulated research on currency basket regimes as alternatives for these economies. However, existing studies have mostly ignored an important characteristic of East Asia, i.e., most of its international trade is invoiced in the U.S. dollars. This paper investigates how the preponderance of dollar invoicing affects optimal currency basket regimes for East Asian economies. I develop a three-country center-periphery sticky-price dynamic stochastic general equilibrium model for the analysis. The model is solved numerically by taking second-order approximations to the policy functions with the expected lifetime utility of households chosen as the welfare criterion. Contrary to the conjecture of existing literature, I show that predominance of dollar invoicing implies that the dollar should receive a smaller weight than suggested by bilateral trade shares between emerging markets in East Asia and the United States. The results hinge on the interaction of different degrees of pass-through implied by the choice of invoice currency and endogenous responses of monetary policies in the center countries.     

External adjustments and coordinated exchange rate policy in Asia

In this paper, we estimate structural VAR models with contemporaneous restrictions based on neo-classical and Keynesian theories to investigate whether the cause of current account surpluses for East Asian economies is a “saving glut” or undervalued currencies. Analytical results show that the major determinant of the current account is the real effective exchange rate for all East Asian countries with the exception of China for which the major determinant is domestic GDP. Accordingly, the recently requested revaluation of the Chinese yuan may not be an effective policy for reducing the Chinese current account surplus, and may affect other Asian current accounts. We also investigate whether a Chinese currency revaluation would contribute to the improvement of current account imbalances in East Asia and find that a revaluation would, indeed, improve the current accounts of Japan, Korea, Indonesia, and Thailand. Since the trade structures of major East Asian countries are substitutes with that of China, a Chinese currency revaluation might not lead to a decrease in East Asian current account surpluses. Coordination of currency policy among East Asian countries is, therefore, needed to solve the global current account imbalance.     

亚洲区域汇率的短期变动——对亚洲货币单位(AMU)月度指标的检验

在亚洲汇率合作进程中,区域篮子货币的设想最为引人注目。本文针对Ogawa等(2005)推出的亚洲货币单位(AMU)指数,运用月度数据对双边汇率变动进行说明,试图揭示影响区域货币对AMU汇率变动的主要经济因素和国别差异,评价AMU作为区域篮子货币的合理性。实证结果表明,区域各主要经济体与货币篮子之间的汇率变动具有某些共同特征,汇率表现的时间惯性基本一致,对美元汇率比较敏感,这意味着将上述指标纳入到区域汇率合作监控体系下具有现实合理性,但是影响变量的差异同时也意味着汇率合作上仍将面临很大的挑战。     

What Should the Weights of the Three Major Currencies be in a Common Currency Basket in East Asia?*

We consider what type of regional common currency should be introduced in East Asia in the future. The common currency basket is, in itself, more desirable as an anchor currency. In this paper we define two types of currency basket and investigate the long‐term sustainability of adopting a common currency basket in East Asia. From our empirical results, a larger weight (but less than 100 percent) for the US dollar in the common currency basket tends to make bilateral exchange rates among East Asian countries stable in the long run.     

Exchange rates,global imbalances,and interdependence in East Asia

The paper analyzes East Asian interdependence in the face of global imbalances. A macro-econometric multinational model is used, describing Korea, Japan, China and the rest of East Asia in their respective relations with the United States as well as with the rest of the world. US imbalances and their expected consequences, notably a depreciation of the dollar and the slowdown of US demand, have rather contrasted effects on East Asian economies, depending on relative magnitudes of the two components. Korea is more affected by the dollar depreciation while China is more exposed to the US slowdown. Japan, less open and less dependent on the US market, is less touched. The correction of East Asian exchange-rate misalignments, which have prevailed since the beginning of the 2000s, would badly affect East Asian economies if undertaken too abruptly. Lastly, the perspective of creating an area of stabilised exchange rates between won, yen and other currencies, organized either as a common currencies basket system or in a regime based on the ACU, is explored preliminarily. Sets of simulations comparing adjustment mechanisms between East Asian countries, with or without the possibility of monetary adjustment, illustrate the cost of precluding exchange-rate adjustments in the case of asymmetric demand shocks.     

The evolving renminbi regime and implications for Asian currency stability

The Chinese authorities described the management of the renminbi after its 2005 unpegging from the US dollar as involving a basket of trading partner currencies. Outside analysts have detected few signs of such management. We find that, in the 2 years from mid-2006 to mid-2008, the renminbi strengthened gradually against trading partners’ currencies within a narrow band. In mid-2008, the financial crisis interrupted this experiment and the bilateral renminbi/dollar exchange rate stabilised at 6.8. The 2006-2008 experience suggests that a shared policy of gradual nominal effective appreciation renders East Asian currencies quite stable against one another. Such a shared policy would create favourable conditions for regional monetary cooperation.     

Asian Currency Baskets: An Answer in Search of a Question?

This paper considers whether an intra regional currency basket and the associated divergence indicators could play a useful role in official exchange rate surveillance. Recently, proponents of an Asian currency basket have referred to the role the European Currency Unit played in constructing exchange rate divergence indicators as evidence of the usefulness of intra regional currency baskets for exchange rate monitoring. The paper shows that such indicators have a number of features that can lead to them obscuring underlying changes in exchange rates and that the signals they emit will often be difficult to interpret. In addition, the use of regional currency baskets for surveillance can lead to potentially serious N − 1 problems in circumstances when there is not agreement about which regional currencies will be the anchor currencies.

Invoicing currency and the optimal basket peg for East Asia: Analysis using a new open economy macroeconomic model

An important characteristic of trade in Asia is that the US dollar is the dominant invoicing currency. This fact might have a consequence on the region's choice of the currency regime. To investigate this possibility, I develop a three country “new open economy macroeconomics” model that consists of East Asia, Japan, and the US. Assuming that East Asia pegs its currency to a basket of the other two's currencies, the optimal basket weights are derived numerically. It is shown that the weights under a realistic invoicing pattern are drastically different from those in the textbook case of “producer currency pricing.” J. Japanese Int. Economies 20 (4) (2006) 569–589.     

Is Asian Currency Unit Attractive to East Asian Economies？

Pegging the RMB exchange rate to the Asian currency unit (ACU) has not, at least in the short term, been proved a better solution than pegging to the US dollar or pegging to a G‐3 (US$, Japanese yen and euro) currency basket. Although the Asian currency unit can help Asian economies to keep the relative price of regional currencies stable, the cost of joining a formal regional monetary cooperation is the relinquishment of the autonomy of their domestic policies. Asian monetary cooperation needs to provide more potential benefits if it is to attract Asian economies. We argue that Asian monetary cooperation should be designed to solve the problem of regional trade imbalance, and regional exchange rate policy coordination should be adopted as the first step towards exchange rate cooperation.

High‐Frequency Contagion of Currency Crises in Asia*

Using daily data from the Asian currency crisis, the present paper examines high‐frequency contagion effects among six Asian countries. The ‘origin’ (of exchange rate depreciation, or decline in stock prices) and the ‘affected’ (currencies, or stock prices) in the daily spillover relationship were defined and identified. Indonesia is found to be the main origin country, affecting exchange rates of other countries. Contrary to conventional wisdom, evidence of high‐frequency crisis spillover from the Thai exchange rate to other currencies was weak at best. There exists a high‐frequency contagion in stock markets among East Asian countries. Contagion coefficients are positively correlated with trade indices, indicating that investors lower their financial assessment of a country that has trade linkage to a crisis origin country within days, if not hours, of a shock.     

Was it really a dollar peg?: The exchange rate policies of East Asian countries, 1980–1997

This paper examines the exchange rate policies of East Asian countries during the period preceding the currency crisis of 1997, in an attempt to ascertain the extent to which they could be considered, as they frequently are, as a dollar peg. We do so by estimating the implicit weights of foreign currencies in the nominal exchange rate determination of East Asian currencies by means of a time-varying parameter model. The crucial element of our approach concerns how the weight of the Japanese yen was altered in response to the movement of the yen–dollar exchange rate. It is found that, while the weight of the U.S. dollar was large and the weight of the Japanese yen was small for the period as a whole, the weight of the yen was raised in some of the countries in the early 1990s. In particular, the Korean and Malaysian authorities raised the weight of the yen when the yen depreciated against the U.S. dollar, while the Singaporean authorities raised the weight of the yen when the yen appreciated against the dollar.

Monetary Integration In Eastern And Southern Africa: Choosing A Currency Peg For Comesa

African countries involved in monetary integration projects have been advised to peg their currencies against an external anchor before the definite fixing of exchange rates. In this study, we estimate optimum currency area indices to determine, between four alternatives, which international currency would be the most suitable anchor for Common Market for Eastern and Southern Africa (COMESA) members and for a set of other selected African economies. We conclude that the euro and the British pound prevail over the US dollar or the yen; that the euro would be the best pegging for most, but not all, COMESA members; and that some of these economies display evidence of more intense integration with third countries, with which they share membership in other (overlapping) regional economic communities, than within COMESA.     

Asian Currency Crisis and the Generalized PPP: Evidence from the Far East

The present paper investigates the effects of the Asian currency crisis of 1997–1998 on the generalized PPP between several real exchange rates of the Far East countries. Monthly log of real exchange rates of the currencies of Thailand, Malaysia, Indonesia, the Philippines and South Korea vis-à-vis the US dollar and the Japanese yen during 1990–2004 are applied in the investigation. Further tests are conducted between exchange rates vis-à-vis the Thai baht. Tests are conducted for periods before and after the crisis. Results from the Johansen method of multivariate cointegration show a substantial change in the relationship between these real exchange rates before and after the Asian currency crisis. This result is found using rates based on three currencies: US dollar, yen and baht.     

TRADE PATTERNS AND EXCHANGE RATE REGIMES: TESTING THE ASIAN CURRENCY BASKET USING AN INTERNATIONAL INPUT‐OUTPUT SYSTEM

This paper aims at analyzing exchange rates and trade patterns of Indonesia, Malaysia, the Philippines, Thailand, China, Korea, Singapore, and Taiwan in relation to Japan and the United States, with reference to the Asian currency crises in 1997. In order to analyze these issues, we constructed an international input‐output model linked with macroeconometric models of the ten countries/regions. Analyses on the Asian exchange rates with a currency basket peg framework show that the Asian exchange rate policy was the de‐facto dollar peg policy. As for trade patterns in relation to the yen‐dollar rate; when a country/region's industrial structure is similar to that of Japan's and the yen is weak, the appropriate change of the yen's weight proves to hold its competitiveness. By contrast, the weak yen shows a decrease of its imports, regarding complementary structure. In either case, however, effects are limited.     

Retrospect of the Chinese Exchange Rate Regime after Reform： Stylized Facts during the Period from 2005 to 2010

In the present paper, we estimate the de facto RMB exchange rate regime, the currency basket, the floating band and the foreign exchange market pressure before and after the reform of the Chinese exchange rate regime in 2005. We find the following stylized facts： the value of the RAIB became stable after the reform; the weight of the US dollar remained high in the basket, while other currencies remained statistically significant; and the floating band gradually increased to lO percent during 2005-2008, and then greatly narrowed from the late summer of 2008 under the assumption of a yearly resetting interval. We find that the foreign exchange market pressure increased from 2005 to 2008. A possible reason is that the weight of the US dollar in the basket was slightly lower than the share of the US dollar in total transactions on the Chinese foreign exchange market. Therefore, it is reasonable for China to adopt a dollar peg exchange rate regime.     

Managing the renminbi: should China peg to a trade‐weighted basket?

Pegging the renminbi (RMB) to the US dollar since 1994 has characterised China's exchange rate policy under a fixed peg or appreciating crawling peg. The current policy, announced in June 2010, of ‘floating with reference to a basket’ made the RMB 25 per cent stronger against a trade‐weighted basket by early August 2015, while it was 10 per cent stronger against the US dollar. Thus, 14 percentage points arose from changes in the cross rates of the other currencies, notably from the fall of the euro since December 2014. Devaluation of the RMB by 3 per cent in August 2015 just covered the effective appreciation since December 2014. Effects of the cross rates of other currencies could be eliminated by managing the external value of the RMB with reference to a genuine trade‐weighted basket. This could be a suitable intermediary exchange rate regime for China, as the risks associated with free floating are still great. Diversifying further the currency composition of the foreign exchange reserves and other foreign assets of the Chinese government, from US dollars towards euro and yen assets, would be a natural parallel shift. The euro–US dollar–yen exchange rates in late summer 2015 may offer a good opportunity to carry out this move.     

Restructuring East Asian exchange rate regimes

This paper investigated the degree of misalignment of the East Asian currencies against the U.S. dollar and against the Japanese yen under a de facto dollar-pegged exchange rate regime (January 1995 to May 1997). We found that overvaluation against the yen started in the Malaysian ringgit and the Philippine peso from January 1996 and the Thai baht from June 1996. Although the Indonesian rupiah and the Korean won against the yen were still undervalued in May 1997, degree of misalignment of both currencies narrowed from April 1995. Large withdrawal of Japanese claims after the financial crisis reduced Japanese bank lendings from $123.8 billion to $85.9 billion in end-June 1998. In 1998, Japanese Foreign Direct Investment (FDI) to East Asia fell as much as 44% from the previous year. In conclusion the paper stresses the importance of the stability in yen/dollar exchange rate to avoid large volatility in Japanese capital flow.     

BASKET PEGS AND EXCHANGE RATE REGIME CHANGE: AUSTRALIA AND NEW ZEALAND IN THE MID‐SEVENTIES*

The adoption of a basket peg by China in July 2005 raised interest in this form of exchange rate regime. This paper explores the emergence of the basket peg in the early 1970s, using New Zealand and Australia as case studies to examine why it was adopted, how it operated, and their policy‐makers' use of it to influence various goals. We highlight the complexity of regime choice following the collapse of Bretton Woods. For Australia and New Zealand, the basket peg was a plausible (although interim) solution when they were reluctant either to peg to a single currency or float.     

International Price Linkage within a Region: The Case of East Asia

This paper investigates how “prices” in East Asian economies correlate with those in Japan and the United States. The analysis is particularly noteworthy because although the East Asian economies are geographically close to Japan, their currencies have been tied more closely to the U.S. dollar. In this paper, we analyze two different types of “prices”: overall price levels in terms of the same currency and relative prices among different commodities. We demonstrate that overall price levels in the East Asian economies are more closely related to those in the United States. However, the relative prices in East Asia, especially those in Taiwan and Korea, are more closely correlated with those in Japan. These price correlation patterns are in marked contrast with those in other regions.J. Japan. Int. Econ.December 1993,11(4), pp. 643–666.
