Banka Sermaye Tamponu, Portföy Riski ve İş Çevrimleri Üzerine Bir Not

Abstract

This paper examines the impact of business cycle on bank capital buffer and portfolio risk using quarterly data for commercial banks operating in the Turkish banking industry for the period 2002Q1-2012Q2. The results indicate that the business cycle and capital buffer are negatively related, suggesting that banks’ capital buffers increase (decrease) as economic conditions worsen (improve). The results also indicate that banks default risk has a positive and significant impact on capital buffer, while capital buffer has a negative and significant impact on default risk. The results further suggest that banks do not benefit from revenue diversification and larger banks hold less capital buffer. Finally, banks that earn higher profit hold more capital buffer and banks that make more profit are exposed to less risk

Abstract

Bu çalışmada iş çevrimlerinin bankaların sermaye tamponları ve portföy riskleri üzerindeki etkisi, Türk bankacılık sektöründe faaliyet gösteren ticari bankaların 2002Q1:2012Q2 dönemi için çeyreklik veriler kullanarak incelenmiştir. Çalışma bulguları iş çevrimleri ile sermaye tamponu arasında ters yönlü bir ilişkiye işaret etmekte; bir diğer deyişle bankaların sermaye tamponlarının ekonomik koşullar kötüleştikçe (iyileştikçe) arttığını (azaldığını) göstermektedir. Çalışmanın bir başka bulgusu da bankaların temerrüt riskinin sermaye üzerindeki etkisinin pozitif, sermaye tamponunun temerrüt riski üzerindeki etkisinin ise negatif ve istatistiksel olarak anlamlı olduğu yönündedir. Ayrıca, Türk Bankacılık sistemindeki ticari bankaların gelir kaynaklarındaki çeşitlilikten yararlanamadıkları, büyük bankaların daha az sermaye tamponu tuttuğu ve son olarak da; karlılık oranı daha yüksek olan bankaların daha fazla sermaye tamponu tutarken, yine bu bankların daha az temerrüt riski taşıdığı da çalışmanın diğer bulguları arasındadır
