Indian banks issued a net ₹19,905 crore in Certificates of Deposit (CDs) in October 2026, opting to tap short-term wholesale funds rather than raising retail deposit rates. This strategy allows banks to manage immediate funding requirements with greater flexibility. Investors should watch how this reliance on wholesale funding impacts bank profit margins and long-term liquidity stability.
Indian banks are currently navigating a delicate balance between managing liquidity and controlling the cost of funds. In October 2026, lenders largely chose to issue Certificates of Deposit (CDs) to secure necessary capital, effectively bypassing the need to hike interest rates on retail savings or fixed deposits. This tactical shift allows financial institutions to secure funding without committing to the long-term interest burdens associated with retail deposits.
The scale of this shift is notable. Market data for October 2026 shows a net incremental increase in CD issuance of ₹19,905 crore. While banks managed ₹78,290 crore in maturing instruments, they issued fresh CDs totaling ₹98,195 crore. The cost of this funding has also risen, with the weighted average rate for new issuances reaching 6.93%. This represents a 36-basis point repricing compared to the instruments that matured, highlighting the rising cost of securing capital in the wholesale market.
This decision follows the Reserve Bank of India’s October 7, 2026, decision to hike the repo rate by 25 basis points to 5.50%. Furthermore, updated RBI deposit norms that came into effect on October 1, 2026, have provided banks with increased flexibility to price bulk deposits based on their Liquidity Coverage Ratio requirements. By utilizing the CD route, banks can adjust their funding levels more dynamically than they could with retail term deposits, which are generally locked in for longer durations.
For investors, this reliance on wholesale funding carries specific implications. While CDs offer a quick solution to immediate liquidity needs, they are typically more expensive than stable retail deposits. With one-year CD rates currently trading at a premium of approximately 250 basis points above the repo rate, the cost of capital is elevated. If banks continue to depend heavily on this short-term funding instead of growing their retail deposit base, it could create asset-liability management challenges. Furthermore, if banks are unable to pass these higher wholesale funding costs on to borrowers, their net interest margins could come under pressure in upcoming quarters.
Investors may monitor future quarterly results to assess how the mix of wholesale versus retail deposits changes. Key monitorables include the bank's ability to maintain healthy deposit growth, the stability of their net interest margins, and the overall cost of funds reported in official filings. Observing how banks manage their liquidity buffers and reliance on short-term market borrowing will provide insight into their financial resilience as interest rate conditions continue to evolve.
