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.     

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.     

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.     

The Dollar Exposure of Japanese Companies

The bulk of Japanese exports and imports are denominated in U.S. dollars rather than Japan's local currency, the yen. The consequences of dollar invoicing depend importantly on the extent to which Japanese companies hedge their dollar exposures. If they fully hedge their dollar exposures, then the choice of invoicing currency will not influence the yen profits of Japanese companies. This paper examines the degree to which Japanese companies hedge by estimating their exposure to movements in the dollar. Using Japanese stock market data and an international version of the CAPM model I estimate the extent to which Japanese company returns are correlated with changes in the yen–dollar exchange rate. The results suggest many Japanese companies are indeed exposed to yen–dollar movements and that dollar appreciations generally are positively correlated with firm returns. Since over the period 1984 to 1995, the dollar depreciated by 36% relative to the yen, it follows that the values of Japanese companies fell as a consequence of their dollar exposure.J. Japan. Int.

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.     

Asian foreign exchange risk exposure

We find that about 25 percent of Asian firms experienced economically significant exposure effects to the US dollar and 22.5 percent to the Japanese yen for the period January 1993 to January 2003. The overall extent of exposure is not sample dependent; a depreciating (appreciating) Asian currency against foreign currencies has a net negative (positive) impact on stock returns. The extent to which firms are exposed to exchange rate fluctuations varies with return horizons; short-term exposure seems to be relatively well hedged, where considerable evidence of long-term exposure is found. Firms with weak liquidity positions tend to have smaller exposures. J. Japanese Int. Economies 21 (1) (2007) 16–37.     

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.

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.     

The Long-Run Purchasing Power Parity for the Yen: Historical Overview

This paper examines the long-run behavior of the yen/dollar real exchange rate. Several series are spliced to compose long Japanese consumer and wholesale price indices, long U.S. consumer and wholesale price indices, and the yen/dollar exchange rate, from 1879 to 1995. The CPI-based real exchange rate tended to depreciate in the pre-WWII periods, but strongly appreciated in the post-WWII periods. The WPI-based real exchange rate did not show any trend in the pre-WWII periods, but appreciated moderately in the post-WWII periods. The unit root tests were not rejected for the CPI-based real exchange rate series, but some of them were rejected for the WPI-based real exchange rate series, suggesting mean reversion property only for the WPI-based series. The Balassa–Samuelson hypothesis to explain a drift and/or a trend in the real exchange rate series had only a weak support.J. Japan. Int. Econ.,December 1997,11(4), pp. 502–521.

Forecasting the Euro exchange rate using vector error correction models

Forecasting the Euro Exchange Rate Using Vector Error Correction Models. — This paper presents an exchange rate model for the Euro exchange rates of four major currencies, namely the US dollar, the British pound, the Japanese yen and the Swiss franc. The model is based on the monetary approach of exchange rate theory which uses fundamental macroeconomic variables to explain the exchange rate. A crucial point when using such a model is its proper estimation through cointegration analysis. The euro exchange rate model is therefore estimated in the form of a Vector Autoregressive (VAR) model with cointegrating vectors (VECM). We find that when cointegration analysis is undertaken properly, the naive random walk prediction can be out-performed for the US dollar, the British pound and the Japanese yen, but not for the Swiss franc.     

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.

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.     

Exchange rate systems and linkages in the pacific basin

This paper analyzes the exchange rate systems of 10 Pacific Basin economies and linkages of their currencies with the major currencies. The recent advances in time series analysis, including unit root tests and cointegration tests, are utilized for this purpose. The results suggest that while many Pacific Basin developing economies are inclined to have a peg or crawling peg system and peg their currencies primarily to the U.S. dollar, the influence of the Japanese yen in this region is also strong, especially on the exchange rates of the Asian newly industrializing economies. For Australia and New Zealand, their exchange rates move in tandem.     

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.     

The ASEAN dollar standard in the post-crisis era: A reconsideration

This paper examines the role of global currencies in ASEAN exchange rate regimes. The investigation considers the post-crisis era from January 1, 1999 through December 31, 2007 and focuses on the five original members of ASEAN (Indonesia, Malaysia, Philippines, Singapore, Thailand) plus Vietnam. Unlike most papers that use classical regression analysis of logarithmic data in first differences to detect the influence of various foreign currencies on particular Asian currencies, this paper considers modern time series analysis more seriously. In particular, this paper finds evidence of cointegration among individual ASEAN currencies and some of the global currencies, indicating a long-run relationship. Examination of the cointegrating vectors yields four main findings. First, there is a notable absence of a clear US dollar standard. Second, the yen is downright unimportant, suggesting that ASEAN currencies are quite far from a yen standard. Third, ASEAN currencies are also quite far from a euro standard. Fourth, and most surprisingly, the UK pound is very important. These results are at odds with the traditional (short-run) regressions which suggest that ASEAN is on a dollar standard, although it is not a perfect dollar standard because coefficients are not at unity and various other currencies are significant in different equations. Hence, the overall conclusion from this research is that there is a wide variety of influences on ASEAN exchange rates in both the long run and the short run. This suggests that ASEAN, as a group, is not pursuing – and is in fact not ready for – a global-currency standard.     

The Role of Nominal Anchor Currencies in Exchange Rate Arrangements

This paper studies the evolution of exchange rate arrangements of almost all countries in the world over the period 1970–1996. It examines both officially reported and empirically observed exchange rate arrangements. Several findings are obtained. First, the relative economic size of countries under fixed exchange rate regimes has not declined as dramatically as the measure based on reported arrangements would indicate. Second, the U.S. dollar has been the most dominant, global anchor currency because many developing economies, particularly those in Asia, Latin America, and the Middle East, have attempted to stabilize their exchange rates to the dollar. Third, the reserve currency composition is determined by the constructed measure of the net currency-area size in addition to the own-economic size of the reserve currency country. Fourth, as a result of the transition to the final stage of EMU, the euro is expected to emerge as the world's second most dominant anchor currency. While the Japanese yen will continue to play a less significant role as nominal anchor, its role in East Asia is expected to rise gradually.J. Japan. Int. Econ.December 1998,12(4), pp. 334–387.

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.     

Japanese vocal intervention and the yen/dollar exchange rate

This paper examined the patterns of Japanese vocal intervention and its influence on the yen/dollar exchange rate using the daily data between January 2000 and August 2003. The major findings of this paper are as follows. First, vocal intervention that is leaning against the wind was found to be successful as opposed to lean-with-the-wind intervention which had mixed results in its effectiveness. Second, vocal intervention turned out to be more effective when it was intended for yen depreciation than for yen appreciation. Third, in the cases of leaning against the wind and yen depreciation intended interventions, the Japanese authorities normally relied on vocal intervention and engaged in actual intervention only when repeated vocal intervention proved ineffective.     

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.
