Abstract
Purpose – Non-performing assets (NPAs) have been a cause of concern for the banking sector across the
world and have invited a lot research interest, especially for emerging economies. In India, the NPAs grew
many folds and reached alarming levels in 2013. The available mechanisms, such as Corporate Debt
Restructuring Scheme, were not adequate to address this issue. The Central Reserve Bank of India with the
Government of India introduced various guidelines, schemes and regulations like framework for revitalizing
distressed assets to tackle NPAs during the period 2013-2017. Taking the case of India, the purpose of this
paper is to examine policy initiatives and analyse the impact of regulatory shocks on the equity market
returns and the systematic risk of individual banking stocks using an extended version of the market model.
Design/methodology/approach – In this study, the authors design the experiment to explore the
reaction of banking stocks to the various regulatory measures and also measure the change in systematic risk
for these stocks as a result of the regulatory changes. Following the approach suggested by Soraokina and
Thornton (2015), the authors use the extended market model to test the reaction of banking company stocks to
the regulatory measures.
Findings – The study finds that banking stocks did not earn signi ficant abnormal returns on the announcement
of these measures. However, the systematic risk of the banking index reduced significantly on the introduction of
regulatory measures, and this risk reduction has been primarily in the stocks of private sector banks.
Research limitations/implications – This paper provides insights on the equity market’s short-term
reaction to the reform initiatives introduced by the government. The scope of the paper is with respect to one
emerging economy, India, which underwent a series of regulatory reforms to tackle the banking NPA
problem.
Originality/value – The paper fills an important research gap where the impact of schemes and
regulations is captured for an emerging economy like India. It tries to bring forth the importance of these
reforms and how an investor perceives the same. This paper tests for changes in systematic risk as measured
by market beta as well as measures cumulative abnormal returns associated with important events in the
process of regulatory reforms happening in India from 2013 to 2017.
