BANKA FİNANSMANINDA SÜRÜ DAVRANIŞI:TÜRKİYE’DE KATILIM BANKALARI ÜZERİNE BİR ARAŞTIRMA

Bu çalışma Türkiye’de katılım bankalarının finansman kararlarındaki sürü davranışlarını incelemeyi amaçlamaktadır. Sürü davranışı, 2010-2020 dönemleri arasında Lakonishock, Shleifer ve Vishny (LSV) ve Frey, Herbst ve Walter (FHW) ölçümleri kullanılarak analiz edilmiştir. Bununla birlikte, bu çalışma sekiz farklı sektöre verilen finansman için LSV ve FHW değerlerinin hesaplanmasına olanak sağlamaktadır. Sonuçlar, katılım bankalarının finansman kararlarında sürü davranışında bulunduklarını göstermektedir. Öte yandan, bankalar, özellikle piyasadaki dalgalanmalar sırasında daha fazla finansman desteği verme eğilimindedirler. Bu belirsiz koşullar altında toptan ticaret ve komisyonculuk ile inşaat sektörleri piyasayı domine eden sektörler arasında yer almaktadır. Aynı zamanda, bankalar bilgiye ulaşmanın daha zor olması sebebiyle, çoğunlukla küçük işletmelerin faaliyet gösterdikleri sektörlere finansman desteği verirken sürü davranışında bulunmayı tercih etmemektedirler.

HERD BEHAVIOR IN BANK LENDING:EVIDENCE FROM PARTICIPATION BANKS IN TURKEY

This paper aims to examine participation banks’ herd behavior in their lending decisions in Turkey. Herding was analyzed by using the Lakonishock, Shleifer and Vishny (LSV) and Frey, Herbst and Walter (FHW) herding measures during the period from 2010 to 2020. The study allows to calculate the LSV and FHW measures for loans outstanding to eight different industries, as well. The results provided an evidence of significant herding in participation banks’ lending decisions during the entire sample. On the other hand, banks’ lending decisions tend to be affected more, in particular, during fluctuations in the market. Wholesale trade&brokerage and construction industries are dominant borrowers under these uncertain conditions. Consistently, banks do not prefer to herd in their lending decisions to industries which small sized businesses mostly operate in due to the fact that gathering information is much more difficult.
