Evaluating financial stress indicators: evidence from Indian data

Abstract

Purpose The purpose of this study is to assess alternative financial stress indicators for India in terms of tracing crisis events, mapping with the business cycle and the macroeconomic effect of stress indices. Design/methodology/approach The study constructs the composite indicator of systemic stress of Hollo, Kremer and Lo Duca (2012) for India using two different methods for computing time-varying cross-correlation matrix, namely, exponentially weighted moving average (EWMA) and dynamic conditional correlation-generalized autoregressive conditional heteroscedasticity (DCC-GARCH). The derived indices are evaluated with widely used, equal variance and principal component weighting indices in terms of tracing stress events, mapping with the business cycles and the macroeconomic effect. For this purpose, the study identifies various episodes of financial stress and uses the business cycle dates in the sample covering from January 2001 to October 2018. Findings The results suggest that stress indices based on EWMA and DCC-GARCH accurately identify the well-known stress periods and capture the recession dates and show an adverse effect on economic activity. Primarily, the DCC-GARCH-based stress index emerges as a better indicator of stress because it efficiently locates all the major-minor events, traces the build-up of stress and reverts to the normal level during stable times. Practical implications The DCC-GARCH-based stress index is a very useful indicator for policymakers in regularly monitoring India’s financial conditions and providing timely identification of systemic stress to avoid adverse repercussion effects of the financial crisis. Originality/value The 2007–2008 financial crisis and subsequent recurrent instability in the financial markets highlighted the requirement for an appropriate financial stress indicator for a timely assessment of the system-wide financial stress. To the authors’ knowledge, this is the first study that incorporates the systemic nature of financial stress in the construction of stress indices for India and provides a holistic evaluation of the financial stress from an emerging country’s perspective.

Evaluating the Impact of Financial Stability and Monetary Stability on Economic Growth: Evidence from an Emerging Economy

“…Similarly, recent studies by Duprey (2020); Ilesanmi and Tewari (2020);Ishrakieh, Dagher, and El Hariri (2020); Mundra and Bicchal (2021) show an economic decline and FS have a negative association between a country's GDP and economic development. Lastly, Hayat et al (2021) stated that Global economies have been impacted by the COVID-19 epidemic, particularly in light of the actions taken by the government regarding compulsory lockdowns and social segregation.…”

Exchange Rate Volatility and Financial Stress: Evidence from Developing Asia

“…While investigating volatility spillovers, directional spillover and transmission of volatility has been observed from stock market to foreign exchange market; spillover “bursts” have been found more profound during crises periods (Diebold & Yilmaz, 2009). Furthermore, existing research provides empirical evidence of quantifying financial stress and its spillover distinctly for emerging economies (Moyo & Le Roux, 2020; Mundra & Bicchal, 2020). A robust model to understand the trend and interaction of exchange rate volatility and financial stress is an evident research gap in the context of developing nations.…”

“…Penelitian ini bertujuan untuk melihat sejauhmana dampak variabel makroekonomi terhadap perkembangan harga saham sektor industri makanan dan minuman selama masa sebelum dan saat pandemic covid 19 serta volatilitas/kerentanan pergerakan harga saham dampak dari perubahan variabel makroekonomi. Kajian terhadap perkembanayang dilakukan tentang harga saham terhadap variabel makroekonomi banyak dilakukan, antara lain dilakukan oleh (Liu dan Srestha, 2008); (Hsing, Y., Hsieh, W, 2012); (Venkatraja, B, 2014); (McMillan, David G and Aviral Kumar Tiwari, 2016); (Mundra, Sruti and Motilal Bicchal, 2020).…”
