Bandhan Bank's financial history since banking conversion has been characterized by extraordinary profitability in the growth phase (FY2016–FY2019), followed by significant stress and volatility as geographic concentration, microfinance sector disruptions, and the COVID-19 pandemic tested the franchise (FY2020–FY2022), and a subsequent recovery phase that has demonstrated the underlying resilience of the core business model. In FY2019 — the last full fiscal year before the Gruh merger and COVID disruption — Bandhan reported net profit of approximately Rs 1,952 crore on a loan book of approximately Rs 44,000 crore, representing a Return on Assets of over 3% and a Return on Equity exceeding 25%. These were exceptional metrics by any banking benchmark — Bandhan was the most profitable bank in India by RoA in that year, a reflection of the extraordinary spread on its microfinance book and its lean operating cost structure (inherited from the MFI model of running high-volume, low-cost field operations). The Gruh Finance acquisition, completed in 2019, fundamentally changed Bandhan's financial profile. The all-stock transaction increased total equity capital, diluted the microfinance's share of the loan book, and brought a higher-quality (lower NIM but lower credit cost) mortgage portfolio. In purely financial terms, the merger was dilutive to near-term RoA and NIM metrics — adding a low-yield mortgage book to a high-yield microfinance book — but strategically essential for portfolio diversification and regulatory compliance. COVID-19 and the subsequent Assam disruption delivered Bandhan's most severe financial stress. In FY2021 and FY2022, the bank's Gross NPA ratio rose sharply — peaking at approximately 10–11% at the gross level — as microfinance collections collapsed during lockdowns and the Assam political disruption prevented normal recovery even as the rest of India normalized. Provisions against these NPAs consumed the bank's profitability: net profit fell sharply from the pre-COVID peak, and return metrics deteriorated significantly. The stock price, which had traded at premium multiples reflecting the extraordinary pre-COVID profitability, corrected substantially. The recovery from FY2023 onward has been meaningful. As Assam stabilized, restructured accounts resolved, and Bandhan's credit processes adapted to the post-disruption environment, GNPA ratios declined toward the 5–7% range. Net profit recovered, with FY2023 net profit returning to approximately Rs 2,000–2,500 crore. The balance sheet crossed Rs 1,40,000 crore in total assets, making Bandhan one of India's larger private sector banks by absolute size despite its unusual origin. The NIM, while compressed relative to the pre-Gruh peak, remained strong at approximately 7–8%, still among the highest in the Indian banking sector.
