Abstract

The probability of default (PD) is the essential credit risks in the finance world. It provides an estimate of the likelihood that a borrower will be unable to meet its debt obligations.PurposeThis paper computes the probability of default (PD) of utilizing market-based data which outlines their convenience for monetary reconnaissance. There are numerous models that provide assistance to analyze credit risks, for example, the probability of default, migration risk, and loss gain default. Every one of these models is vital for estimating credit risk, however, the most imperative model is PD, i.e., employed in this paper.Design/methodology/approachIn this paper, the Black-Scholes Model for European Call Option (BSM-CO) is utilized to gauge the PD of the Jammu and Kashmir Bank, Bank of Baroda, Indian Overseas Bank, and Canara Bank. The information has been taken from a term of 5 years on a yearly premise from 2012 to 2016. This paper demonstrates how d2 in Black Scholes displayed help in assessing the PD of the various firms.FindingsThe fundamental findings of this paper are whether there are any mean contrasts between the mean differences of PD between the organizations utilizing ANOVA and the Tukey strategy.

Summary

Introduction

Credit risk (default), estimation, and administration have turned out to be a standout among the most critical parts in budgetary financial matters. It is expected that (Bohn et al 2005; Saunders and Allen 2002; Merton 1974): The underlying asset (St) is replaced by the value of the firm (V) The strike price (K) in a call option is replaced by the debt (D) The risk-free rate of interest is replaced by the expected growth of the firm In such manner, the significance of d_2 has been clarified. To estimate the distance to default, we need the Back Scholes Formula for a European call option which is given by: St. Replace: The risk-free rate of interest r by the expected continuously compounded return on value of the firm μV.
