許遠東時期和彭淮南時期台灣央行干預外匯市場行為比較之研究 / The research for comparing the intervention behaviors of Central Bank of Taiwan in foreign exchange markets:Hsu Yuan-Tung versus Peng Huai-Nan曾斐筠 Unknown Date (has links)
本研究利用公開的新聞資料做分析,探討近兩任央行總裁許遠東先生以及彭淮南先生在干預外匯市場的行為上有何不同,將干預新聞資料設虛擬變數利用最小平方法做迴歸分析。迴歸結果發現,彭淮南先生在外匯市場的干預是有即時的效果且對匯市的反應較為迅速。而許遠東先生在外匯市場的干預則是有遞延的效果,干預行為也相較溫和。 / This paper analyzes public news to examine different behaviors between Hsu Yuan-Tung and Peng Huai-Nan when they intervened in foreign exchange markets. The paper uses intervention news as dummy variables and then performs regression analysis by Ordinal Least Squares. Empirical results show that the intervention behavior of Mr. Peng is instant effect and the reaction to foreign exchange markets is quick. However, it is deferred and moderate for Mr. Hsu.

外資證券投資、央行干預和外匯市場的關連性分析: 以台灣、南韓、印度和菲律賓為例 / The analysis of correlation among securities investment from foreigners, central bank intervention and foreign exchange market : take Taiwan, South Korea, India and Philippines as the examples林佳瑜 Unknown Date (has links)
隨著全球化的趨勢,金融自由化的浪潮席捲全球金融體系,解除資本管制為世界潮流,然而對於小型開放的經濟體,特別是以出口為導向的國家而言,為了維持出口競爭力的優勢,央行干預外匯市場已成為一種經常性政策,因此本研究根據外資在股票市場淨買超金額、各幣別兌美元匯率及路透社關於台灣、南韓、印度與菲律賓央行干預匯市報導等資料,藉由向量自我迴歸模型等方法進行實證分析。實證研究顯示本幣匯率貶值幅度對央行干預、外資淨買超皆呈顯著負向影響,表示當本幣匯率貶值幅度上升(下降),該國貨幣貶值(升值)時,在市場上可觀察到央行進行阻升(阻貶)的動作以及出現質疑央行阻升(阻貶)的訊息,同時,外資也會因而退出(進入)股市。除了菲律賓外,在台灣、南韓和印度,外資於股票市場淨買超增加對本幣匯率貶值幅度的影響效果皆落後三日,才反向顯著地影響本幣匯率貶值幅度,表示資本移入的增加會導致外匯供給增加,進而使該國匯率升值。對台灣與南韓而言,市場確定央行干預報導雖正向影響本幣匯率貶值幅度,即央行阻升(阻貶)行為,能讓該國匯率貶值(升值),但並不顯著;而市場質疑央行干預報導則顯著正向影響其本幣匯率貶值幅度。而菲律賓則為市場確定央行干預報導顯著正向影響其本幣匯率貶值幅度;市場質疑央行干預報導正向影響但不顯著。在印度,市場確定央行干預報導反向影響,而市場質疑央行干預報導正向影響本幣匯率貶值幅度,但皆不顯著。

外匯市場的技術分析與央行干預 / Technical trading rules in the exchange rate markets and central bank intervention吳至剛 Unknown Date (has links)
在這篇文章裡我們採用了White所提出的真實檢驗法(Reality Check)來解決探勘資料偏誤(Data-snooping bias)的問題,結果顯示從1980年到2008年間,技術分析法則的確可以幫助投資人在日圓兌美元及英鎊兌美元這兩個外匯市場獲利;我們也發現在外匯市場最普遍的技術分析方式─移動平均法(moving average)表現不如其他的技術分析法則,而通道突破法(channel break-out)的表現則明顯優於其他技術分析法則。
除了檢驗技術分析方法的獲利性之外,我們也嘗試著探討技術分析方法的獲利性與央行干預之間的關係,追隨Szacmary與Mathur在1997年所發表的論文,我們把技術分析法則擴充為在真實檢驗法中所使用到的所有法則,並且盡可能加長分析的期間。結果顯示技術分析法則的獲利與央行干預並不存在任何特定的關係。 / In this paper we construct a huge universe of simple trading rules and apply White’s Reality Check to mitigate data-snooping bias then detect the profitability of technical trading rules. We find that technical analysis is useful no matter in the full sample time or each subsample period. The channel break-out method outperforms the other methods in our finding while the profitability of the most commonly used moving average method is worse than the others. Furthermore, we inspect the relationships between the returns of technical trading rules and central bank intervention. The results suggest that there’s no evident relationship between the return series of trading rules and central bank intervention and are not consistent with the view of our following previous study.

亞洲央行干預外匯市場的有效性及對美國存託憑證價差的影響 / 無張美菁, Chang, Mei Ching Unknown Date (has links)
【第一篇論文中文摘要】
本文使用路透社央行干預匯市的新聞報導,探討哪些因素可以提高亞洲央行成功干預匯市的機率,研究期間為2005年1月至2011年4月。此研究期間涵蓋全球金融風暴和美國採行量化寬鬆政策,因此,亞洲貨幣在逐步對美元升值後發生大幅度的貶值。研究結果顯示印尼、馬來西亞、菲律賓、新加坡、台灣及泰國的央行採取逆風而行的策略是有效的干預方式,而且多個國家在同日干預匯市及第一日的干預會有較高成功的機率。
【第二篇論文中文摘要】
本文透過不同的研究方法針對亞洲國家央行干預匯率市場的有效性再次驗證,研究期間為2005年1月至2011年4月,實證結果顯示亞洲國家在次貸風暴期間面臨美元升值的壓力,央行會採取賣美元的方式來干預匯市,但是這種干預匯市的方式卻僅能減緩美元升值的趨勢,其中以印尼盾、新加坡元、新台幣紛紛對美元貶值較為明顯,而在次貸風暴發生之後,美國實施量化寬鬆政策造成亞洲國家卻面臨美元貶值的壓力,各國央行改採買美元的方式來干預匯市,但是此種干預匯市的方式也只造成美元緩慢貶值的趨勢,其中印尼盾、馬來西亞令吉、新加坡元、韓圜、泰銖分別對美元升值的趨勢較為明顯,此現象反應亞洲央行干預匯市是採取逆風而行的策略,雖然能降低匯率的波動,但無法改變匯率的升貶值趨勢。
【第三篇論文中文摘要】
本研究是在探討印度、印尼、南韓、馬來西亞、新加坡、泰國及台灣央行透過干預匯率市場,對其國家的公司在美國發行存託憑證折溢價的影響,研究期間為2005年1月至2011年4月。研究結果顯示央行對匯市干預造成的變動,確實會影響到該國公司在美國發行的存託憑證產生折價的情形。另外,亞洲央行使用買美元干預匯市的作法會對該國公司在美國發行的存託憑證產生溢價,而央行透過賣美元干預匯市的作法會對該國公司在美國發行的存託憑證產生折價的影響,但是由於樣本資料的限制,其效果在統計上並不顯著。由公司層面的分析可以看出央行透過賣美元來干預匯市對其國家的公司在美國發行的存託憑證會有明顯產生折價的影響。 / 【第一篇論文英文摘要】
Using Reuters’ news reports on central bank interventions, we investigate the factors that increase the odds of intervention success by Asian central banks in the foreign exchange market from January 2005 to April 2011. This period coincides with the global credit crisis and quantitative easing policy, which have engendered a sharp depreciation followed by a gradual appreciation of Asian currencies. The results show that leaning-against-the-wind intervention strategies are effective in Indonesia, Malaysia, Philippines, Singapore, Taiwan, and Thailand. We also find that joint and first day interventions are associated with higher odds of effective intervention.
【第二篇論文英文摘要】
This paper examines the effectiveness of central bank interventions in the foreign exchange market from January 2005 to April 2011 in Asia. The results show that the central banks in Asia intervene in the foreign exchange markets by selling U.S. dollars to prevent severe depreciation of local currencies during the global credit crisis. However, central bankers can only slow down the trend of depreciation of local currencies against U.S. dollar. The currencies apparently depreciate against U.S. dollar in Indonesia, Singapore, and Taiwan. After the global credit crisis, Asian countries confront appreciations of local currencies due to the US quantitative easing policy. The central banks in Asia intervene by purchasing U.S. dollars in the foreign exchange market. Nevertheless, intervention strategies slowly reduce U.S. dollar depreciations. The foreign exchange rate apparently appreciate against U.S. dollar in India, Malaysia, Singapore, South Korea, and Thailand. Results show that Asian central banks adopt leaning-against-the-wind intervention strategies during the sample period. Their interventions in the foreign exchange market can only reduce fluctuations in the foreign exchange rate, but fail to reverse the trend of Asian exchange rates.
【第三篇論文英文摘要】
This paper examines whether Asian central bank interventions in the foreign exchange market affect the discount or premium of American Depositary Receipt (ADR) of Asian companies from January 2005 to April 2011. The sample consists of companies from Indian, Indonesia, South Korea, Malaysia, Singapore. Empirical results show that central bank interventions increase ADR discounts of companies in Asian countries. In addition, interventions by purchasing U.S. dollars result in higher ADR premiums, and the strategies of selling U.S. dollars affect ADR discounts. Though some of the empirical results are not statistically significant due to limited sample size, results based on individual firms show that selling USD interventions by Asian central banks have a significant impact on their ADR discounts.
