The Reserve Bank of India clarified that rising credit-deposit ratios are not standalone signs of banking stress. As the ratio hit 82.2% in March 2026, the central bank highlighted strong capital buffers and changed funding models. Investors should watch how deposit growth trends impact bank profit margins.
The Reserve Bank of India (RBI) has addressed concerns regarding the rising credit-deposit (CD) ratio in the banking sector. The CD ratio, which measures the proportion of deposits that a bank has deployed as loans, climbed to 82.2% in March 2026, up from 68.6% in September 2021. This rise has led to debates about whether banks are over-leveraged or facing liquidity stress.
In its latest assessment, the central bank stated that this metric should not be viewed as a standalone indicator of financial instability. The RBI explained that modern banking practices have evolved. In the current system, the act of extending credit often generates new deposits within the financial network, meaning credit creation is no longer strictly limited to pre-existing deposit mobilization. Furthermore, banks have been adjusting their balance sheets, moving away from heavy investment portfolios toward active credit expansion, which naturally pushes the CD ratio higher.
From an investor perspective, the concern has been that if loan growth significantly outpaces deposit growth, banks may struggle to fund these loans without relying on more expensive short-term borrowings, such as Certificates of Deposit (CDs). This can pressure net interest margins (NIMs)—the difference between interest earned on loans and interest paid on deposits—if banks cannot raise deposit rates effectively or if depositors move their savings into alternative avenues like mutual funds.
The banking system appears to have strong fundamental buffers to manage these shifts. The RBI highlighted that the gross non-performing asset (GNPA) ratio remains low at 1.8%, and the capital adequacy ratio stands at 17.7%. Additionally, the liquidity coverage ratio, which indicates a bank's ability to meet short-term obligations, is at 124.2%, well above regulatory requirements.
The case of HDFC Bank serves as a practical example of how institutions manage this balance. Following its merger, the bank saw its CD ratio climb to approximately 110%. However, through aggressive strategies to attract deposits, the bank successfully recalibrated this ratio to around 96%. This demonstrates that while the ratio can fluctuate, large institutions have tools to stabilize their funding position.
For investors, the key monitorable remains the speed of deposit mobilization. While the systemic health indicators are strong, the ability of banks to grow their low-cost deposit base will be crucial in maintaining profit margins. Investors should watch future quarterly reports for commentary on funding costs and whether banks are successfully attracting traditional retail deposits to keep their reliance on market borrowing under control.
