This study investigates the impacts of bank capital regulations on credit cycles. In the study, the investigation of the effects of banks' capital ratios on the loan supply of the Turkish banking sector with bank-level data and panel VAR econometric methods is important as it is the first attempt to address the issue within this framework for Turkey. The findings obtained from the analysis with data covering the period from 2002Q4 to 2019Q2 and 26 domestic and foreign-owned banks operated in Turkey show that tightening capital requirements have a significant negative effect on the loan supply of the banking sector. The results of the study imply that regulations on capital requirements may be important in planning policy practices to control banks' loan supply. Overall, it can be concluded that macro-prudential policy tools such as countercyclical capital requirements and countercyclical capital buffers may be used to smooth the credit cycle and, thus, financial cycles in Turkey.

Banka Sermayesi Şokları ve Kredi Büyümesi: Türk Bankacılık Sektörü

Öz

Bu çalışma banka sermayesine ilişkin düzenlemelerin kredi dalgalanmaları üzerindeki etkilerini sorgulamaktadır. Çalışmada bankaların sermaye oranlarının Türk bankacılık sektörünün kredi arzı üzerindeki etkilerinin banka düzeyindeki veriler ile panel VAR ekonometrik yöntemleri kullanılarak incelenmesi, Türkiye için meseleyi bu çerçevede ele alan ilk teşebbüs olması bakımından önemlidir. Türkiye’de faaliyet gösteren 26 yerli ve yabancı bankaya ait, 2002Q4 ve 2019Q2 dönemini kapsa-yan veriler ile yapılan analizlerden elde edilen bulgular sermaye yeterliliklerinin sıkılaştırılmasının bankacılık sektörünün kredi arzı üzerinde anlamlı negatif etkilere sahip olduğunu göstermektedir. Bulgular sermaye yeterlilikleri üzerindeki düzenlemelerin, bankaların kredi arzını kontrol amaçlı politika uygulamalarının planlanmasında önem taşıyabileceğini ima etmektedir. Genel olarak konjonktürel sermaye yeterlilikleri ve sermaye tamponları gibi makro ihtiyati politika araçlarının Türkiye’de kredi dalgalanmalarını dolayısıyla da finansal dalgalanmaları düzleştirmede kullanılabileceği sonucuna varılmaktadır.
