2008 Krizi Döneminde Türkiye’de Döviz Piyasası Baskısının İncelenmesi: Mevsimsel Eşbütünleşme Analizi

Ülkeleri etkileyen sistematik risk faktörleri büyük öneme sahip olup özellikle kriz dönemlerinde daha da öncelikli hale gelmektedir. Sistematik risk faktörlerinden birisi de kur riski olup döviz piyasası baskısı (DPB) bu riskin bir göstergesi olarak alınmaktadır. Bu çalışmada, 2008 küresel kriz döneminde Türkiye'de DPB ve DBP üzerinde etkili olan değişkenler arasında mevsimsel eştümleşmenin olup olmadığı 2004-2012 dönemi için araştırılmıştır. Çalışmada cari açık, gösterge tahvil faiz oranı, toplam yükümlülükler ve VIX endeksi ile DPB arasındaki ilişki incelenmiştir. Uygulamanın ilk aşamasında, aylık veriler için geliştirilen HEGY sınaması kullanılarak serilerdeki mevsimsel birim kökün varlığı incelenmiştir. Değişkenlerin durağanlık düzeyleri belirlendikten sonra değişkenler arasındaki uzun dönemli ilişki mevsimsel eştümleşme modeli kurularak incelenmiştir. Elde edilen bulgular serilerin mevsimsel birim kök içerdiği ve eşbütünleşik olduğu yönündedir. Tüm modellerde eştümleşme sonucu veren ±5 /6 frekansına göre bağımsız değişkenler ile DPB arasında pozitif ilişki saptanmıştır

Investigating Exchange Market Pressure in Turkey in the 2008 Crisis Period: Seasonal Cointegration Analysis

Systematic risk factors are very important for economies and their impact becomes significant especially in a crisis period. One of the systematic risk factors is exchange rate risk and exchange market pressure (EMP) is taken as an indicator of exchange rate risk. In this study, we have analysed the existence of the seasonal cointegration between EMP and the variables effecting EMP in Turkey for the 2008 global crisis period . We have investigated the relationship between EMP, current account deficit, benchmark bond interest rate, total liabilities and the VIX index. In the first step of the empirical application the HEGY test adapted for monthly data, is used to determine the existence of seasonal unit root in the variables. After the determination of stationarity of the variables, a long run relationship between the variables is investigated using seasonal cointegration model. The results show that the variables have seasonal unit root and they are seasonally cointegrated. In the model which has all components at ±5 /6, we have found that all variables have a positive relationship with EMP
