TÜRK BANKACILIK SEKTÖRÜNDE 1980-2017 DÖNEMİNDE SERMAYE YETERLİLİĞİ VE KARLILIK ARASINDAKİ İLİŞKİNİN ANALİZİ; FOURIER YAKLAŞIMI

Bankacılık sektöründe sermaye-karlılık ilişkisi büyük önem arzetmekte ve sermaye yeterliliği düzenlemelerinin bankacılık sektörünün karlılığı ve etkinliği üzerindeki etkileri ile bu etkilerin büyüklüğü birçok çalışmaya konu olmaktadır. Özellikle, 2008 yılından itibaren A.B.D ve A.B’de yaşanan krizler, sermaye düzenlemelerindeki yetersizliklerin, krizlerin ortaya çıkması ve büyümesindeki rolünün daha ayrıntılı bir şekilde incelenmesine yol açmıştır. Türk Bankacılık Sektörü incelendiğinde, gelişmiş ve gelişmekte olan ülkelerde faaliyet gösteren birçok bankaya göre, yüksek sermaye yeterlilik ve karlılık rasyoları dikkati çekmektedir. Bu çalışmanın amacı, 1980-2017 dönemi için, Türk Bankacılık Sektörü sermaye yeterliliği ile sektör karlılığı arasındaki ilişkinin incelenmesidir. Türk Bankacılık Sektörü yıllık verileri kullanılarak ekonometrik bir çalışma yapılmıştır. Karlılığa ilişkin indikatörler olarak ROE ve NIM bağımlı değişkenler, sermaye yeterliliğine ilişkin olarak ise, özsermaye/toplam varlıklar ve özsermaye/mevduat+mevduat-dışı kaynaklar oranları bağımsız değişkenler olarak çalışmada kullanılmıştır. Çalışmada elde edilen sonuçlar, sermaye yeterliliğini gösteren sözkonusu oranlar ile karlılık indikatörleri arasında uzun dönemli ilişkiler olduğunu göstermektedir.

Analysis of the Relationship Between Capital Adequacy and Profitability in Turkish Banking Sector Over the Period of 1980-2017; Fourier Approach

The relationship between capital adequacy and profitability has great importance and has been studied widely. The effects of the capital adequacy requirements on bank performance and the volume of these effects are important issues studied. Financial crises experienced in U.S.A and E.U since 2008 have led to the detailed examination of the role of the capital inadequacies in crises. When analysed the Turkish Banking Sector, high capital adequacy and profitability ratios have been standing out, compared to the other banks operating in the other developed and developing market economies. The purpose of this study is to test the relationship between capital adequacy and profitability in the banking sector during the period of 1980-2017 by using the annual data of Turkish banking sector. Dependent variables as ROE and NIM and independent variables as equity/total assets ratio and equity/deposit+non-deposit sources have been used in this study. The results of the study shows that there are long-term relationships between capital adequacy ratios and profitability indicators.
