Does an Exclusive Relationship with Government Banks Matter during a Climate Shock?

Review of Finance, Volume 30, Issue 3, May 2026, 949–994
We provide novel evidence on the role of firms’ banking relationships with government banks (GOBs) during a climate-related shock when relief funds are unavailable. Using variation in the locations of rainfall shocks and firms' banking relationships, we find that firms maintaining exclusive banking relationships with GOBs (GOB firms) secure more debt relative to other firms during rainfall shocks. We do not find such effects for firms that maintain exclusive relationships with private banks, foreign banks, or maintain multiple banking relationships. We also find that GOB relationships are particularly beneficial for firms that are more vulnerable to rainfall shocks, have long-term relationships with GOBs, and are, at the same time, healthier compared to other firms. With regard to real effects, GOB firms invest more and remain profitable than other firms during rainfall shocks. Overall, our results highlight the benefits of GOB relationships for firms during climate shocks.

Liquidity-adjusted value-at-risk using extreme value theory and copula approach

In this study, we propose the application of the GARCH-EVT-Copula model in estimating liquidity-adjusted value-at-risk (L-VaR) of energy stocks while modeling nonlinear dependence between return and bid-ask spread. Using the L-VaR framework of Bangia et al. (1998), we present a more parsimonious model that effectively captures non-zero skewness, excess kurtosis, and volatility clustering of both return and spread distributions of energy stocks. Moreover, to measure the nonlinear dependence between return and spread series, we use multiple copulas: Clayton, Gumbel, Frank, Normal, and Student-t. Based on the statistical backtesting and economic loss functions, our results suggest that the GARCH-EVT-Clayton copula is superior and most consistent in forecasting L-VaR compared with other competing models. This finding has several implications for investors, market makers, and daily traders who appreciate the importance of liquidity in market risk computation.

The extant literature suggests that banks play an important corporate governance role, and influence firms' reporting choices and investments. Yet, we know very little about how the government banks' (GOBs) multidimensional goals influence these important corporate control decisions. Using an exogenous shock that empowers banks, but heterogeneously affects incentives to increase the level of scrutiny, I find that firms that have an exclusive relationship with GOBs (henceforth, GOB firms) misreport, inflate their earnings, and over-invest compared to other firms. Moreover, there is no significant improvement in GOB firms' performance after the shock. Rather, there is evidence of a significant increase in risk-taking, which induced them to engage in precautionary savings, compared to that of non-GOB firms. Overall, these results suggest that the GOBs' multidimensional goals allow GOB firms to misreport, and engage in sub-optimal activities. This explains why GOBs end up with a risky set of firms compared to other banks.

Bankruptcy Reform and Financial Intermediation
co-authored with Samit Paul and Prateek Sharma
We exploit cross-sectional variations in regional financial intermediation together with a bankruptcy reform that empowers lenders while emphasizing time-bound reorganization over liquidation, to estimate its effects on credit expansion. We find post-reform, bank lending expands among poor-financial intermediation regions, with firms obtaining more bank debt at lower interest rates. These effects are stronger for larger, older, healthier, and more profitable firms. Mechanisms include private, highly capitalized, and healthy banks extending significantly more credit compared to government, lowly capitalized, and unhealthy banks. Real activities rise in poor-financial intermediation regions as firms boost investments, while households rely less on employment-guarantee schemes.
