The determinants of net interest margin in the Turkish Banking sector. Does bank ownerhip matter?

Türk Bankacılık Sektöründe Net Faiz Marjının Belirleyicileri. Mülkiyet Yapısı Etkili midir? Bu çalışmada Türkiye'deki ticaret bankacılığında net faiz marjını etkileyen faktörler bankaların mülkiyet yapısı dikkate alınarak incelenmiştir. Çalışmada kullanılan çeyrek dönemlere ait veri seti 2001-2012 dönemine aittir. Net faiz marjının belirleyicilerini ve bunların mülkiyet yapısına göre etkilerini araştırmak üzerine farklı ekonometrık metotlar kullanılarak elde edilen sonuçlar şöyledir: işlem çeşitliliği, kredi riski ve işlem maliyetleri en önemli faiz marjı belirleyicilerden olup fiyat istikrarı ve banka verimliliğinin faiz marjı üzerinde negatif etkisi olduğu saptanmıştır. Önemli net faiz marjı belirleyicilerden kredi riski, bankanın büyüklüğü, piyasa yapısı ve enflasyon mülkiyet yapısına göre farklı etkiler gösterirken zımni faiz ödemeleri, işlem çeşitliliği ve işlem maliyetleri gibi belirleyiciler mülkiyet yapısından bağımsız etkiye sahip olduğu anlaşılmıştır.

Türk bankacılık sektöründe net faiz marjının belirleyicileri. Mülkiyet yapısı etkili midir?

This research presented an empirical investigation of the determinants of the net interest margin in Turkish Banking sector with a particular emphasis on the bank ownership structure. This study employed a unique bank-level dataset covering Turkeys commercial banking sector for the 2001-2012. Our main results are as follows. Operation diversity, credit risk and operating costs are important determinants of margin in Turkey. More efficient banks exhibit lower margin and also price stability contributes to lower margin. The effect of principal determinants such as credit risk, bank size, market concentration and inflation vary across foreign-owned, state-controlled and private banks. At the same time, the impacts of implicit interest payment, operation diversity and operating cost are homogeneous across all banks.
