The Yen,the US dollar,and the trade weighted basket of currencies: Does the choice of anchor currencies matter in identifying incidences of speculative attacks?

Early constructions of a single crisis index known as the exchange market pressure (EMP) index have largely been based on the fluctuations of the real or nominal exchange rate of a currency against the US dollar—the most commonly accepted anchor currency in the global market. Hardly any studies have however tested the sensitivity of this crisis index to the choice of different “anchor” currencies. To address this pertinent issue, our study considers the EMP indices of the Indonesian rupiah, Malaysian ringgit and Thailand baht constructed by adopting three different exchange rates—the real effective rate, the local currency against the US dollar, and the local currency against the Japanese yen for the period of 1985–2003. The test results indicate that the reported incidences of speculative attacks are highly sensitive to the choice of anchor currencies.     

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.     

Evidence of long-run purchasing power parity: analysis of real asian exchange rates in terms of the Japanese yen

In this paper we find strong new evidence in favour of the long-run purchasing power parity (PPP) hypothesis in the bilateral real exchange rates between the Japanese yen and the currencies of the most important southeast Asian economies only when the presence of several possible structural breaks of the series is taken into account. Such evidence for PPP is weaker for these southeast Asian exchange rates with the US dollar, the German mark and the Australian dollar.     

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.     

Yen bloc or koala bloc? Currency relationships after the East Asian crisis

During the 1990s, several studies found evidence for a “yen bloc”, a significant and strengthening relationship between the Japanese yen and East Asian currencies possibly due to regional trade and investment by Japan. It appears that the Australian dollar now plays a similar role in the East Asian region, and the linkages between the Australian dollar and the Asian currencies show as much support for a “koala bloc” as a “yen bloc”. This study concludes that the US dollar appears to have declined in importance in post-1997 crisis East Asia, while Australia and Japan are becoming increasingly important regional influences.     

On the identification of de facto currency pegs

We describe an exchange rate peg on a dollar/euro/yen basket as an orthogonality condition for bilateral exchange rates vis-à-vis these currencies. This approach avoids the choice of a numeraire and allows simple testing on the composition of the peg. GMM estimation is performed before and after the 1997–1998 crises for up to 139 currencies. We find that the number of pegs has not diminished after the crises. Intermediate regimes, defined as de facto pegs which are not reported as hard pegs to the IMF, have been replaced by hard pegs (primarily as a consequence of the launch of the euro) while the proportion of free floats has not increased. The dollar remains the main anchor currency. J. Japanese Int. Economies 20 (1) (2006) 112–127.     

Optimal Pegs for East Asian Currencies

It has been evidenced that the U.S. dollar is prominent in the exchange rate regimes of Asian countries. This paper shows that the relative stability of Asian exchange rates against the U.S. dollar until the 1997 crisis is not accounted for by the theory of optimum currency areas, in contradiction to the situation in Europe vis-à-vis the deutsche mark. An alternative framework is proposed where the absence of a yen bloc is explained by the mismatch between the country distribution of trade and the currency distribution of the debt. It is shown that the lack of cooperation makes Asian countries underweight the yen in their implicit basket pegs.J. Japan. Int. Econ., March 1999,13(1), pp. 44–60.

Measuring currency pressures: The cases of the Japanese yen,the Chinese yuan,and the UK pound

We investigate bilateral currency pressures against the US dollar for three currencies: the Japanese yen, the Chinese yuan, and the UK pound during the period 2000:Q1 to 2009:Q4. We employ a model-based methodology to measure exchange market pressure over the period. Conversion factors required to estimate the pressure on these currencies are computed using a time-varying coefficient regression. We then use our measures of currency pressures to assess deviations of exchange rates from their market-equilibrium levels. For the yen, our measure of currency pressure suggests undervaluation during the initial part of our estimation period, a period during which the Bank of Japan sold yen in the foreign exchange market. We find persistent undervaluation of the yuan throughout the estimation period, with the undervaluation peaking at about 20% in 2004 and 2007. For the pound, the results indicate low pressure – suggesting a mainly free-floating currency – throughout the sample period. These results appear consistent with the policies pursued by the central banks of the currencies in question.     

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.     

Effect of exchange rate return on volatility spill-over across trading regions

This paper examines the effect of realized exchange rate returns on the volatility spill-over between the euro–US dollar and US dollar–yen currency pairs across the five trading regions: Asia, Asia–Europe overlap, Europe, Europe–America overlap and America. Modelling the interaction between returns and volatility in an autoregressive five-equation system, we find evidence that depreciation of the US dollar against the yen has a greater impact on the US dollar–yen volatility spill-over than appreciation in the subprime crisis period. Appreciation and depreciation of the US dollar against the euro does not appear to have an asymmetric effect on the euro–US dollar volatility spill-over. Our results support the notion that the yen may have been preferred to the euro as a ‘safe-haven’ currency relative to the US dollar during the subprime crisis period.     

Exchange-rate policy in East Asia after the fall: how much have things changed?

This paper evaluates the changes in the exchange-rate policies of East Asian economies in the aftermath of the currency crisis and the process in which the exchange-market stability was re-established. The empirical analysis evaluates the changing roles of the yen and the US dollar in the currency baskets, the shifts in the volatility of the underlying macroeconomic fundamentals and their implications on exchange-rate management, the exchange-market perception of credibility and risk of the postcrisis exchange-rate regimes, and the process of reversion to fundamental values after the massive currency depreciation.The analysis shows that after the abandonment of the quasi-dollar peg, the yen had gained a greater weight in the currency baskets and the greater flexibility in which the exchange rates are being managed serve to accommodate the greater volatility in the macroeconomic fundamentals. The improvement in the macroeconomic conditions and the greater credibility that has been acquired by the regional monetary authorities had allowed the exchange market to stabilize and enabled the exchange rates to revert back to their fundamental values.     

A tale of Asian exchange rate management: Romance of the three currencies

Asian currencies lack regional policy coordination and are therefore subject to volatilities such as the Asian currency crisis of 1997/99. As the Asian currencies have already been observed to be ‘flying-in-unison’, a stable exchange rate arrangement can be helpful as the next step of evolution for regional financial stability. We consider that creating a cluster effect from coordinated efforts/policies of policy-makers can lead to regional exchange rate stability. To demonstrate this cluster effect, a three-party-game is computed for an Asian bloc, viz-á-viz US dollar and the Euro, based on a Nash and a cooperative equilibrium. The cluster effect would generate external and internal pressures that work towards the formation of a regional currency, although the exact form of exchange rate regime would have to await political consensus. There are substantial welfare gains within Asia network economy through currency cooperation. The formation of an Asian currency bloc would also create counter-balance to the current dominance of the US dollar and the Euro. Like the epic story of Three Kingdoms who sought hegemony in Chinese history, the Asian currency bloc will contend with many possible outcomes of competition as well as cooperation.     

East Asian equity markets,financial crises,and the Japanese currency

The paper studies the interactions between the US and four East Asian equity markets. The focus is on the change in the information structure/flow between these markets triggered by the 1997 Asian financial crisis. It is shown that the information structure during the crisis period is different from that in the non-crisis periods. While the US market leads the four East Asian markets before, during, and after the crisis, it is Granger-caused by these markets during the financial crisis period but not in the post-crisis sample. Further, in accordance with concerns reported in the market, the Japanese currency is found to affect these equity markets during the crisis period. The Japanese yen effect, however, disappears in the post-crisis sample. The Japanese currency effect is quite robust as it is found from both local currency and US dollar return data and in the presence of Japanese stock returns. J. Japanese Int. Economies 21 (1) (2007) 138–152.     

Stabilization of effective exchange rates under common currency basket systems

We investigate the extent to which a common currency basket peg would stabilize effective exchange rates of East Asian currencies. We use an AMU (Asian Monetary Unit), which is a weighted average of ASEAN10 plus 3 (Japan, China, and Korea) currencies, as a common currency basket to investigate the stabilization effects. We compare our results with another result on stabilization effects of the common G3 currency (the US dollar, the Japanese yen, and the euro) basket in the East Asian countries [Williamson, J., 2005, A currency basket for East Asia, not just China. In: Policy Briefs in International Economics, No. PB05-1. Institute for International Economics]. We obtained the following results: first, the AMU peg system would be more effective in reducing fluctuations of the effective exchange rates of East Asian currencies as a number of countries applied the AMU peg system increases in East Asia. Second, the AMU peg system would more effectively stabilize the effective exchange rates than a common G3 currency basket peg system for four (Indonesia, the Philippines, South Korea, and Thailand) of the seven countries. The results suggest that the AMU peg system would be useful for the East Asian countries whose trade weights on Japan are relatively higher than others. J. Japanese Int. Economies 20 (4) (2006) 590–611.     

Effects of Exchange Rates on Debt, Debt Services and Public Debt Management in Thailand in the 1980s

This paper attempts to evaluate the effects of exchange rates on debt, debt services, and public debt management in Thailand in the 1980s. A simple differentiation technique is used to decompose the changes in debt and debt services into 'management' and 'exchange rates' effects. The latter became more pronounced in the second half of the 1980s largely because of the increased volatility in exchange rates among key currencies. The public sector responded to these changes by adjusting the debt portfolio through new commitment and refinancing, as well as restricting the level of external debt. As a result, a significant amount of debt services was saved in 1989, when the exchange rates among major currencies began to settle down, although the same adjustments initially led to temporary increases in the levels of debt and debt services during the mid-1980s.
Moreover, the diversified structure of public external debt made it possible to compensate a change of debt or debt service in one currency denomination by a counter change of those in another currency denomination. Such a compensating relationship (e.g. between Yen and US dollar during 1985–87) helped stabilise the effects of exchange rates. The baht is now pegged to a basket of currencies. In theory the effects of exchange rates may be completely neutralised if the debt portfolio reflects the weight of each currency in the basket. Such relationships may be incorporated to improve the efficiency of public debt management.     

Fear of appreciation in East and Southeast Asia: The role of the Chinese renminbi

Our study brings into light evidence of the important role of the Chinese renminbi in shaping the exchange rate behavior of a select group of East Asian currencies. Results obtained suggest that there is an additional dimension to the ‘fear of appreciation’ or ‘fear of floating-in-reverse’ behavior, initially coined by Levy-Yeyati and Sturzengger (2007) with regard to the experiences of this group of East Asian currencies. In particular, we find that there is a greater degree of aversion to appreciation of these East Asian currencies—specifically, the Philippine peso and the Thailand baht—against the Chinese renminbi than against the US dollar. This heightened fear of appreciation against the Chinese currency confirms that trade competition matters in this part of the world and that this fear to appreciate plays a central role in the exchange rate management of major East Asian currencies. As envisaged, the increasing role of China as a major trading hub in the region as well as globally, implies that the Chinese renminbi would exert a growing significant influence on other currencies in the region.     

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.

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.     

How Did the Dollar Peg Fail in Asia?

In this paper, we have constructed a theoretical model in which the Asian firm maximizes its profit, competing with the Japanese and the U.S. firms in their markets. The duopoly model is used to determine export prices and volumes in response to the exchange rate fluctuations vis-à-vis the Japanese yen and the U.S. dollar. Then, the optimal basket weight that would minimize the fluctuation of the growth rate of trade balance was derived. These are the novel features of our model. The export price equation and export volume equation are estimated for several Asian countries for the sample period from 1981 to 1996. Results are generally reasonable. The optimal currency weights for the yen and the U.S. dollar are derived and compared with actual weights that had been adopted before the currency crisis of 1997. For all countries in the sample, it is shown that the optimal weight of the yen is significantly higher than the actual weight.J. Japan. Int. Econ.,Dec. 1998,12(4), pp. 256–304.

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.
