Abstract

Bu çalışmada Türkiye’de finansal sistem üzerinde önemli etkileri ve ağırlığı olan kamusal sermayeli mevduat bankalarında dolarizasyon ile kârlılık arasındaki ilişki incelenmiştir. Araştırmada Halkbank, Vakıfbank ve Ziraat Bankasının 2005-2021 dönemine ait üçer aylık dönemsel verileri kullanılmıştır. Çalışmada literatürde ilk kez mevduat dolarizasyonu, bilanço içi para birimi uyumsuzluğu ve yabancı para türev ürünler olmak üzere dolarizasyon bağıntılı üç değişken birlikte ele alınmıştır. ARDL sınır testi yaklaşımı ile elde edilen bulgular her üç değişkenin de kamusal sermayeli mevduat bankalarında kârlılık üzerinde istatistiksel olarak anlamlı etkileri olduğunu ortaya koymaktadır. Ancak bu etkilerin yönleri bankalar arasında ve kısa-uzun dönem ayırımında farklılık göstermektedir.

The Impacts of Dollarization on the Profitability of Turkish State-owned Deposit Banks

Abstract

This study explores the association between dollarization and profitability in state-owned deposit banks, which play a significant role in the financial system in Türkiye. Quarterly data from Halkbank, Vakıfbank and Ziraat Bank spanning from 2005 to 2021 are used in the research. Three dollarization-related variables - deposit dollarization, balance sheet currency mismatch and foreign currency derivatives - are included jointly in a study for the first time in the literature. Although the directions differ between banks in the short- and long-run, the estimation coefficients obtained by applying Panel ARDL techniques imply that all dollarization-related variables have statistically significant impacts on the profitability of Turkish state-owned deposit banks.
