Abstract

This study examines the role of peer effect on bank leverage decisions in the Turkish banking sector. Data from 21 deposit banks operating between 2007 and 2022 were analysed using the Panel-Corrected Standard Errors (PCSE) method. In the model, the dependent variable is the bank leverage ratio, the independent variable is peer bank leverage, and the control variables are bank size, liquidity ratio, and loss provisions/total assets ratio. The findings show that peer influence is positive and significant, indicating that their peers' financial behaviour influences banks' leverage decisions. The study aims to demonstrate that bank decisions are shaped not only by internal factors but also by sectoral interactions.

Özet

Bu çalışma, Türk bankacılık sektöründe akran etkisinin banka kaldıraç kararları üzerindeki rolünü incelemektedir. 2007-2022 döneminde faaliyet gösteren 21 mevduat bankasına ait veriler Panel-Corrected Standard Errors (PCSEs) yöntemiyle analiz edilmiştir. Modelde bağımlı değişken banka kaldıraç oranı, bağımsız değişken akran banka kaldıracı; kontrol değişkenler ise banka büyüklüğü, likidite oranı ve zarar karşılıkları/toplam varlıklar oranıdır. Bulgular, akran etkisinin pozitif ve anlamlı olduğunu, bankaların kaldıraç kararlarını akranlarının finansal davranışlarından etkilenerek aldığını göstermektedir. Çalışmanın motivasyonu, banka kararlarının yalnızca içsel faktörlerle değil, sektörel etkileşimlerle de şekillendiğini ortaya koymaktır.
