Can RBL Bank’s retail deposit surge force mid-tier private banks to rethink their liability strategy?

RBL Bank Limited’s Q1 FY26 performance has drawn attention for a reason beyond its 192% quarter-on-quarter profit rebound. The private lender posted an 11% year-on-year rise in total deposits to ₹1,12,734 crore, but what stands out is the 16% year-on-year surge in granular deposits—defined as balances below ₹3 crore—which climbed to ₹57,934 crore and now form 51.4% of the total deposit base. In a banking environment where cost of funds and liability stability are under increasing scrutiny, this structural shift could become a template for other mid-tier private sector banks, including Federal Bank and DCB Bank, as they look for ways to insulate themselves from funding cost volatility and tighten their retail banking footprint.

Analysts have pointed out that granular deposits are no longer just a side metric; they are becoming an essential marker of a bank’s ability to sustain profitability when interest rate cycles turn. By reducing reliance on volatile bulk deposits, RBL Bank has attempted to strengthen its liability franchise at a time when competitive pressures in retail lending are compressing margins across the private banking space.

How could RBL Bank’s granular deposit growth influence liability management strategies at other mid-tier private sector banks in FY26 and beyond?

RBL Bank’s move to aggressively deepen its granular deposit base signals a calculated liability management strategy. Smaller deposits tend to be more stable, as they are sourced from a large retail customer base rather than a few corporate clients, which makes the liability structure less sensitive to sudden withdrawals or rate renegotiations. With over half its deposits now in the granular category, RBL Bank is also positioning itself to moderate its funding costs over the medium term. Analysts tracking private banks note that such stability allows for more predictable loan pricing, especially in high-growth segments like secured retail loans and commercial banking.

For other mid-tier banks, this development serves as both a benchmark and a challenge. Federal Bank has historically maintained a strong CASA franchise, but RBL Bank’s 16% granular deposit growth may push it to further accelerate retail-focused initiatives to protect its cost of funds as competition intensifies. DCB Bank, with its relatively smaller footprint and higher corporate deposit reliance, may find it harder to replicate this strategy at the same scale without significant investment in branch expansion and business correspondent networks.

This trend is also reshaping how private banks allocate resources. Industry observers believe that building granular deposits will demand more branch-level engagement, digital acquisition tools, and loyalty-driven savings products. Banks focusing primarily on wholesale deposits might face pressure to rethink their strategy, as institutional investors increasingly view granular deposit growth as a proxy for retail franchise strength and long-term balance sheet stability.

The push toward retail deposits also carries competitive implications in a softening interest rate cycle. With the Reserve Bank of India signaling a pause on further rate hikes, the advantage may shift to banks with stronger retail liability bases, as they can lower lending rates without significantly compressing margins. RBL Bank’s shift is therefore being read not just as a defensive move but as a positioning play for growth, giving it room to price loans more aggressively in secured segments like housing, two-wheelers, and SME finance.

For RBL Bank, the challenge will be sustaining this deposit momentum without significantly raising acquisition costs. Analysts caution that aggressive campaigns to expand granular deposits could temporarily pressure operating expenses, especially if physical branch expansion outpaces digital onboarding efficiencies. However, the medium-term payoff—in terms of funding cost stability and improved investor perception—appears significant enough to justify the effort.

Going forward, other mid-tier private banks are expected to recalibrate their liability mix over the next few quarters. Federal Bank’s existing retail strengths make it well-placed to leverage this trend, while DCB Bank and smaller private lenders may need to invest more heavily to achieve similar results. As analysts put it, the next phase of competition among mid-tier banks will not just be about loan book growth but about who controls the cheapest and most stable funding sources in a market that is becoming increasingly cost-conscious.
