Dynamic characteristics of the daily yen–dollar exchange rate

This paper explores various dynamic properties of daily data for the yen–dollar exchange rate. This empirical study shows that quantitative information articulated with technical trading acts as market-based indicators, thus contributing to the modelling of daily fluctuations in the exchange rate. Value-at-Risk analysis is also performed to demonstrate that allowing for data properties such as skewness is essential for representing the underlying volatility of the yen–dollar rate.     

European monetary arrangements: Implications for the dollar,exchange rate variability and credibility

This paper uses the recent history of the ERM to gain insights into what might happen to exchange rates on the road to EMU. to do this, the paper examines the variability of exchange rates, the transmission of monetary policy between countries, the role of the dollar in ERM exchange rate crises, and ERM members' credibility as measured by the realignment probabilities prior to the September 1992 crisis. We identify two factors that might have contributed to the September 1992 crisis: high German interest rates and weakness of the US dollar. We find that behaviour of exchange rates has changed over time and differs between ERM and non-ERM currencies. We also demonstrate that changes in German short-term interest rates influence interest rates in other ERM countries and vice versa.     

Forecasting and Arbitrage of the Nikkei Stock Index Futures: An Application of Backpropagation Networks

A neural network model was used in forecasting the basis in SIMEX Nikkei Stock Index futures. Results for out of sample show that the neural network forecast performance was better than that of the ARIMA model. Also, a two-way ANOVA confirms that the employed neural network was able to provide the trader with more arbitrage profits than the traditional cost-of-carry model even though it observed relative less profitable arbitrage timing. The results can be attributed to the network';s higher ability to capture nonlinear market patterns.     

Change in Volatility in the Won/U.S. Dollar Daily Exchange Rate:Stochastic Volatility Model

This study estimates the changes in volatility of the won/U.S. dollar dailyexchange rates before and after the Korean currency crisis, using the stochastic volatility model with the ARMAregression error term. We find that the persistence of volatility increased after the Koreancurrency crisis.     

汇率弹性化下人民币汇率波动预测分析

本文选取影响人民币汇率波动的有关结构变量,分别通过线性MA模型和基于遗传算法改进的GABP神经网络模型,对人民币汇率波动进行模拟和预测。通过比较发现,汇率缺乏弹性时期,逐月MA模型的历史拟合和样本外预测效果最优;随着汇率改革的不断推进和汇率弹性化的增强,GABP神经网络模型在汇率波动的模拟和预测方面均有最优表现,故汇率波动预测模型应随汇率弹性及其波动特性不同因时制宜。同时结果表明,汇率弹性化能够加深汇率波动及其结构变量间的均衡关系,利率市场化改革应与汇率市场化改革协调推进。     

Overstatement of Implied Variance in the Dollar/Yen Currency Option Market

This paper investigates the predictive power of implied variancesextracted from the dollar/yen option prices. Implied variances areestimated from transaction prices of currency options traded on PHLXusing the option pricing model of Garman and Kohlhagen (1983). Incontrast to recent findings on stock and stock index options, theout-of-sample tests indicate that the implied variance is an upwardbiased estimator of future variance; and that the variance forecastsfrom GARCH and historical models do not contain significantincremental information in predicting future variance. Tradingstrategies are also developed to exploit the observed overstatementof variance in the dollar/yen option market. Traders that can executethe delta-neutral trading strategies at the observed markettransaction prices could lock in a significant profits during theperiod examined. However, for investors that facing highertransaction costs, the magnitude of the profits is generally notlarge enough to allow for abnormal risk-adjusted profits.     

美元加息对新兴市场国家的影响与对策

2018年4月以来,美元持续多次加息,多个新兴市场国家本币大幅贬值、股市急剧下跌、债市承压动荡,资本外流压力进一步显现。新兴市场国家金融动荡的导火索以外部因素为主,风险传播渠道以跨境联动因素为主,风险放大渠道以内部因素为主。在美元加息背景下,新兴市场国家要妥善处理自身货币与美元之间的关系,避免过于依赖美元,过多承担短期美元债务。支持法国、德国等提出的建立新独立国际支付体系的倡议,避免部分国家将国际公共的金融基础设施作为制裁手段。     

U.S. Money Supply and China’s Business Cycles

This article models the U.S. dollar as a world currency in a global DSGE framework, and investigates the spillover effects of the U.S. money supply shock on China’s economy. Exchange rate targeting and capital controls in the context of dollar hegemony are investigated. Given a positive U.S. money supply shock, both the inflation and real GDP of China will be below their steady-state levels in the medium term; while for the U.S. there is no inflation pressure. The spillover of liquidity effect exists. Cost-push effects and relative price effects are employed to discuss the transmission mechanism. Under the U.S. money supply shock, a fully liberalizing reform with no capital controls and a floating exchange rate of Renminbi is not the best reform for China.     

The response of the Dollar/Yen exchange rate to economic announcements

The paper examines the impact of major U.S. macroeconomic announcements on the Dollar/Yen exchange rate. We find that these announcements are responsible for most intraday and day-of-the-week volatility patterns in this market and we identify the most important announcements. The initial reaction to a major 8:30 announcement begins around 8:30:10 and lasts until about 8:30:50. A partial price correction is normally observed between 8:31 and 8:32. Price movements after 8:32 are basically independent of those observed earlier although volatility continues to be higher than normal until about 8:55.     

Is foreign exchange intervention by central banks bad news for debt markets?: A case of Reserve Bank of Australia's interventions 1986–2003

We investigate the effects of the Reserve Bank of Australia's foreign exchange interventions on the USD/AUD market and 90-day and 10-year interest rate futures markets for the period July 1986–December 2003. Using recently released revised and updated intervention data, we investigate contemporaneous and disaggregated intervention influences and find significant evidence for (i) intervention effectiveness in moderating the contemporaneous exchange rate movements especially if interventions were cumulative and large, (ii) exchange rate volatility reducing effect with a day's lag, (iii) undesirable interest rate movements following interventions in some periods compromising monetary policy effectiveness, and (iv) a volatility reducing effect of cumulative interventions in the 90-day rate, and a volatility increasing effect of large interventions in both the 90-day and 10-year rate futures. These findings are a unique and significant contribution to the prevailing literature as they demonstrate that the RBA's interventions matter not only for the foreign exchange market but also for the debt markets.
