Financial Integration in the 1920s: A Cointegration Approach

Financial Integration in the 1920s: A Cointegration Approach. - This paper applies the concept of cointegration to analyze the foreign exchange market during the 1920s. The data set consists of daily spot and forward exchange rates for the U. S. dollar, French franc, Belgian franc, Italian lira and German mark, each quoted with respect to the British pound. The authors find that the future spot and forward exchange rates for the U.S., France, Belgium, and Italy are cointegrated. Using a multivariate test for cointegration, they find no evidence of cointegration across markets. There is weak evidence of cointegration among the two neighboring economies of France and Belgium.     

Has the Link Between the Spot and Forward Exchange Rates Broken Down? Evidence from Rolling Cointegration Tests

Recent literature reported conflicting results about the cointegration relationship between the spot and forward exchange rates. Applying rolling cointegration tests to the mark, yen, and Swiss franc with respect to the U.S. dollar for the post-80 period, we find that the relationship between the two rates broke down in the late 1980s. Although they became cointegrated again during the mid-90s, they no longer co-moved proportionally. It is argued that failure to account for such significant structural changes in the data generating process explains, at least partially, the conflicting findings reported in the literature.     

Episodic Nonlinearity in Leading Global Currencies

We perform non-linearity tests using daily data for leading currencies that include the Australian dollar, British pound, Brazilian real, Canadian dollar, euro, Japanese yen, Mexican peso, and the Swiss franc to resolve the issue of whether these currencies are driven by fundamentals or exogenous shocks to the global economy. In particular, we use a new method of testing for linear and nonlinear lead/lag relationships between time series, introduced by Brooks and Hinich (J Empir Finance 20:385–404, 1999), based on the concepts of cross-correlation and cross-bicorrelation. Our evidence points to a relatively rare episodic nonlinearity within and across foreign exchange rates. We also test the validity of specifying ARCH-type error structures for foreign exchange rates. In doing so, we estimate Bollerslev’s (J Econom 31:307–327, 1986) generalized ARCH (GARCH) model and Nelson’s (1988) exponential GARCH (EGARCH) model, using a variety of error densities [including the normal, the Student-t distribution, and the Generalized Error Distribution (GED)] and a comprehensive set of diagnostic checks. We apply the Brooks and Hinich (1999) nonlinearity test to the standardized residuals of the optimal GARCH/EGARCH model for each exchange rate series and show that the nonlinearity in the exchange rates is not due to ARCH-type effects. This result has important implications for the interpretation of the recent voluminous literature which attempts to model financial asset returns using this family of models.     

The Euro and Other Major Currencies Floating Against the U.S. Dollar

This paper discusses the interdependent effects of conditional volatilities in returns of the Euro and other major currencies against U.S. dollar exchange rates (spot rates) since the launch of the Euro, using, for this purpose, the daily data and dynamic conditional correlation (DCC)–GARCH model with country-specific effects. The following conclusions are drawn: there are volatility spillovers (contemporaneous and lagged) in the Euro, Yen, and British pound, the degree of the correlation is high between the Euro and British pound against the U.S. dollar, there is a very strong association between the ECB Euro reference rate (fixing rates) and U.S.-traded spot rates, and finally, the impulse-response of volatility (after the accession of new Member States to the European Union) rapidly diminishes in the spot markets, indicating a short-run dynamic effect.     

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.     

The stock market and the ringgit exchange rate: a note

This paper presents and tests an augmented monetary model that includes the effect of stock prices on the bilateral exchange rates. The model is applied to the ringgit/US dollar (RM/US) and ringgit/Japanese yen (RM/JY) exchange rates. The empirical analysis is conducted by the Johansen method of cointegration. Using the data from the recent float that ends with 1996:Q4, the study is motivated, among others, by an interesting preliminary finding that although the augmented monetary model is cointegrated, it is subject to parameter instability and that the parameter time dependency can be attributed at least partly to a particular subset of the variables in the system including stock prices. We find that a restricted VAR model which imposes exogeneity restrictions on I(1) variables, such as stock prices, among others, exhibits both cointegration and parameter stability. In addition, we demonstrate that exchange rate adjusts to clear any disequilibrium in the long-run relationship. The empirical findings tend to suggest that the equity market is significant in affecting the exchange rate and in explaining at least in part the parameter instability evidenced in the cointegrating system. Hence, we conclude that models of equilibrium exchange rate should be extended to include equity markets in addition to bond markets.     

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.     

Net foreign asset positions and appreciation expectations on the Swiss franc and the Japanese Yen

The paper shows that currencies of countries with persistent current account surpluses and high foreign-currency denominated assets, such as the Swiss franc and the Japanese yen, are under persistent appreciation pressure, particularly when the centres of the world monetary system follow expansionary monetary policies. This limits the choice of exchange rate regime. Given flexible exchange rates, a negative risk premium on the domestic interest rate can emerge. Empirical estimations provide mixed evidence for a negative impact of net foreign asset positions and exchange rate uncertainty on interest rates of international creditor countries at the periphery of the world monetary system.     

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.     

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.     

基于Copula-vines的欧元汇率波动相关性实证研究

欧洲债务危机后,欧元汇率变动趋势值得关注。文章利用copula vines类模型,在考虑汇率条件波动相关性及汇率波动边际分布独立性的条件下,研究了欧元对美元、人民币、港元和日元四种货币汇率波动的相关性。研究结果表明,欧元对美元汇率同欧元对其他三种货币汇率波动存在不一致性,而在欧元对美元汇率既定条件下,欧元对人民币汇率与欧元对港元汇率、欧元对日元汇率的条件相关基本一致,在欧元对美元汇率、欧元对人民币汇率不变的情况下,欧元对港元汇率同欧元对日元汇率的相关性程度很低。     

Optimal Cross-Hedging Alternatives for the CFA Franc

Abstract: Multinational corporations and policy makers in the African Franc Zone face currency risk while participating in international trade or borrowing abroad. This paper investigates managing this currency risk through the foreign currency futures market. An optimal cross-hedging model is derived and empirically tested for alternative overlapping and nonoverlapping cross hedges of one, two, four, and twelve weeks in the British pound, Japanese yen, Swiss franc, and Deutsche mark futures contracts. The results indicate that spot positions in CFA francs can effectively be cross hedged in the Deutsche mark or Swiss franc futures contracts. This research demonstrates that the foreign currency futures market offers potential for less developed countries to reduce their currency risks effectively. Résumé: Les entreprises multinationals et les chargés de politiques dans la Zone Franc Africaine sont exposés au risque de changes en participant dans le commerce international ou empruntant à l'étranger. Cet article examine la gestion du risque de changes extérieurs à travers le marchéà terme des monnaies. Un modéle de couverture croisée optimale est dérivé et empiriquement testé pour des interventions alternatives d'une, de deux, de quatre, et de douze semaines dans les contrats à terme de la livre Anglaise, du yen Japonais, du franc Suisse, et du mark Allemand. Les résultats indiquent que les positions de changes au comptant libelées en francs CFA peuvent être effectivement couvertes dans les contrats à terme du mark Allemand ou du franc Suisse. Cette recherche démontre que les marchés à termes des monnaies offrent l'opportunite aux pays en développement de se couvrir effectivement contre le risque de changes.     

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.     

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.     

Asset Market and Balance of Payments Characteristics: An Eclectic Exchange Rate Model for the Dollar,Mark and Yen

In this paper we use an exchange rate model, which combines asset market characteristics with balance of payments interactions, to examine the nominal effective exchange rates of the German mark, Japanese yen and US dollar for the recent experience with floating exchange rates. Our approach may be interpreted as one which attempts to flesh out the missing links that arise in conditioning an exchange rate solely on relative prices, as occurs in a standard PPP analysis. Amongst the results reported in this paper are: significant, and sensible, long-run relationships for the currencies studied; complex short-run dynamics; a variance decomposition analysis which apportions nominal exchange rate error variances into real and nominal elements.     

An equilibrium foundation of the Soros chart

The most prominent characteristic of the Japanese yen/U.S. dollar nominal exchange rate in the post-Plaza Accord era is near random-walk behavior sharing a common stochastic trend with the two-country monetary base differential augmented with excess reserves. In this paper, we develop a simple two-country incomplete-market model equipped with domestic reserve markets to structurally investigate this anecdotal evidence known as the Soros chart. In this model, we theoretically verify that a market discount factor close to one generates near random-walk behavior of an equilibrium nominal exchange rate in accordance with a permanent component of the augmented monetary base differential as an economic fundamental. Results of a Bayesian posterior simulation with post-Plaza Accord data of Japan and the United States plausibly support our model as a data generating process of the Japanese yen/U.S. dollar exchange rate. The model identifies the two-country differential in money demand shocks as the main generator of the sharp depreciation of the Japanese yen against the U.S. dollar under the Abenomics. We discuss data evidence that the identified money demand shocks are tightly correlated with longer-term interest rate differentials between the two countries.     

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.     

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.     

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.     

Purchasing power parity: Granger causality tests for the yen–dollar exchange rate

The paper analyses the causality between the Japanese prices and the yen–dollar exchange rate. It explains the long-term appreciation trend of the Japanese yen and why the Japanese yen proved strong even during the economic slump of the 1990s. The paper suggests that the appreciation of the Japanese yen forced the Japanese enterprises into price reductions and productivity increases, which put a floor under the high level of the yen and, thus, initiated rounds of appreciation. This corresponds to the conjecture of a vicious (virtuous) circle of appreciation and price adaptation. Further, there is evidence that the yen-appreciation has been accommodated by the Bank of Japan’s monetary policy. This corresponds to the conjecture that the recent Japanese deflation is imposed from outside via the exchange rate.
