Penelitian ini bertujuan untuk menganalisa pengaruh non-performing loan terhadap lending behaviour bank-bank konvensional di Indonesia dengan periode kuartal dari tahun 2006-2015. Selain itu, penelitian ini ingin menguji bagaimana keputusan memberikan pinjaman tersebut kaitannya dengan masalah moral hazard. Dengan metode Threshold Regression oleh Hansen (1999), dan menggunakan rasio Non-Performing Loan sebelumnya sebagai threshold variable, peneliti menemukan adanya masalah moral hazard dimana bank justru meningkatkan pinjaman ketika rasio NPL bank sudah diatas 5,29%. Sementara itu, determinan rasio non-performing loan di Indonesia yaitu tingkat pertumbuhan kredit (LGR), tingkat pertumbuhan kredit periode sebelumnya (l.LGR), rasio modal terhadap total aset (ER), ukuran bank (Size) dan tren waktu (dummy year).

By applying the Threshold Regression method from Hansen (1999) and applying the most recent non-performing loan ratio as the threshold variable, the researcher has found that the moral hazard problem is exist when the NPL ratio exceed 5,29%. The determinants of the non-performing loan ratio in Indonesia are loan growth rate (LGR), last period loan growth rate (1.LGR), equity to total asset ratio (ER), bank size (Size) and dummy year.
