Çalışmada, Türkiye’de faaliyet gösteren ticari bankalarca açılan sektörel kredilerin yoğunlaşması ile kredi riski arasındaki ilişki analiz edilmiştir. 2002:4-2014:2 döneminde üç aylık verilerle yapılan analizlerde, özel, kamu ve yabancı bankalar ayrı gruplar halinde dikkate alınmıştır. Doğrusal panel veri yönteminin kullanıldığı tahminler, sektörel yoğunlaşmanın kredi riskini arttırdığını göstermiştir. Zaman içinde özel ve kamu bankalarında riskli kredilerin toplam kredilere oranı düşmüş, yabancı bankalarda ise artmıştır. Bununla beraber, tüm banka grupları için kredi riskiyle yoğunlaşma arasında pozitif ve güçlü bir ilişki olduğu belirlenmiştir
