The direction of volatility transmission between stock and foreign exchange markets is important for hedging strategy, portfolio management and financial market regulation. This paper examines volatility transmission between stock and foreign exchange markets by applying the multivariate GARCH model in the BEKK framework to Nigerian stock returns and the Naira/USD exchange rate data from January 1996 to March 2013. Results of the empirical analysis show evidence of volatility clustering in both stock and foreign exchange markets. The results also show bi-directional shock transmission between stock and foreign exchange markets, suggesting that information flow in the foreign exchange market impact the stock market and vice versa. Finally, the results show evidence of a uni-directional volatility transmission from the foreign exchange market to the stock market. The implication is for investors vigilantly to monitor and dissect all information in the two markets as part of their investment strategy.

The purpose of this article is to determine whether quickly gained a large share of the Australian dollar in trading on the foreign exchange markets can reduce current in-ternational position euros. The position of AUD has increased in the settlements use of the raw materials. This is especially exacerbated when the Australian economy entered the path of rapid deve-lopment. This happened in spite of the great recession of 2008-2009. In addition, a stronger Australian dollar favors a very low risk of an increase in public debt. This cur¬rency also maintains an AAA credit rating. Central banks added the Australian dollar in¬to their currency reserves. By this way its position is strengthened as an international currency and treated as very safe, despite the correlation with the market raw materials.

W artykule przedstawiono rezultaty analizy kursu walutowego, przeprowadzonej na podstawie modelu stanowego reprezentacji binarno-czasowej. Podstawą tej reprezentacji jest dyskretyzacja kursu, w której każdej zmianie wartości, równej zadanej jednostce dyskretyzacji, są przypisywane dwa parametry: wartość binarna, zgodna z kierunkiem zmiany kursu, oraz czas jej trwania. Do modelowania kursu wykorzystano stanowy model reprezentacji binarno-czasowej, pozwalający na estymację rozkładu prawdopodobieństwa kierunku zmian kursu walutowego w zależności od zmian historycznych. Do analizy wykorzystano 5-letnie dane tickowe kursu EUR/PLN. W rezultacie potwierdzono istnienie zależności pomiędzy kolejnością, kierunkiem oraz czasem trwania poprzedzających zmian kursu a prawdopodobieństwem kierunku przyszłej zmiany.

In the following article results of an exchange rate course analysis are presented, performed based on a state model of binary-temporal representation. Base for this kind of representation is course discretization, in which for every course change equal to a given discretization unit, two parameters are assigned, that is binary value corresponding to the direction of a change, and its duration. In order to model the trajectory, a state model of binary-temporal representation was used, allowing for approximation of the future direction of changes, depending on the change history. Tick data for EUR/PLN pair in a five-year period was used for the analysis. Preformed research confirmed existence of relations between the order, direction and duration of previous changes and the probability of future direction of a change.

Celem artykułu jest ocena skali zmienności kursu złotego w stosunku do euro i dolara, dokonana w porównaniu do kursów innych, wybranych walut krajów Unii Europejskiej: korony czeskiej, korony szwedzkiej, forinta węgierskiego i funta brytyjskiego. Do analizy zastosowano trzy wskaźniki: procentowe odchylenie kursu dziennego od średniej z badanego okresu i od średniej z poprzedzających dwóch lat oraz miernik ERV, a także przeprowadzono analizę korelacji. Zaobserwowano, że skala zmienności kursu złotego w stosunku do euro i dolara w porównaniu do innych walut nie jest zbyt znaczna oraz że stopień powiązania wartości walut z euro jest zasadniczo większy niż z dolarem, co przekłada się na wyższą stabilność ich kursów względem wspólnego pieniądza.

The aim of the paper is to evaluate the scale of volatility of the złoty’s exchange rate against the euro and the dollar, in comparison to the rates of other selected currencies of the European Union member states: Czech koruna, Swedish krona, Hungarian forint and British pound. Three indicators were used for the analysis: percentage deviation of the daily exchange rate from the mean in the studied period and from the mean in the preceding two years and the measure of the ERV, and also the correlation analysis was conducted. It was observed that the scale of volatility of the zloty’s rate against the euro and the dollar compared to other currencies is not very excessive and that the degree of linkage of the currencies’ values with the euro is substantially higher than with the dollar, which translates into greater stability of their exchange rates against the common currency.
