MICRO-DETERMINANTS OF NET INTEREST MARGIN IN TURKISH BANKING SECTOR: EFFECTS OF GLOBAL FINANCIAL CRISIS

Öz

The aim of this paper is to investigate the bank level determinants of Net Interest Margin for commercial banks operating in Turkish Banking Sector. For this purpose a panel data set which consists of countinuosly operated commercial banks during 2002Q4-2017Q4 is analysed using Driscoll-Kraay and difference GMM estimators. Results suggest that bank level variables are more significant in determining net interet margin rather than macro variables. Factors having impact on reducement of margins and thus improvement of intermediation efficiency are credit risk management, cost management and generating alternative income through operation diversity. Moreover banks operated with higher margins priorly seems to maintain this tendency during the next periods. Effects of Global Financial Crisis in 2008 on determinants of net interest margin are also investigated.

TÜRK BANKACILIK SEKTÖRÜNDE NET FAİZ MARJININ MİKRO-BELİRLEYİCİLERİ: KÜRESEL MALİ KRİZİN ETKİLERİ

Öz

Çalışmanın amacı, Türk Bankacılık Sektöründe Net Faiz Marjının banka ölçeğindeki belirleyicilerini tespit etmektir. Bu amaçla 2006 4. Çeyrek ile 2017 4. Çeyrek arasında sürekli faaliyet göstermiş olan ticari bankaların verilerinden oluşan panel veri seti sabit etkiler yöntemi ile analiz edilmiştir. Bulgular bankaların net faiz marjlarının aktif karlılığı, faaliyet giderleri, likidite, mevduat oranı, kredi riski ve kur riskleri ile pozitif; ölçek, özkaynak oranı ve faiz dışı gelirler değişkenleri ile negatif ilişkili olduğunu ortaya koymaktadır. Takipteki krediler, faiz riski ve bilanço dışı işlemler ise net faiz marjı ile ilişkili bulunmamıştır. Ayrıca bankaların uyguladıkları marjlara ilişkin geçmiş eğilimlerini sonraki dönemlerde de devam ettirdikleri görülmüştür.
