The RBI’s repo rate hike to 5.5% is expected to increase net interest margins (NIMs) for large banks by up to 10 basis points, according to IIFL Capital. This rise helps banks earn more on loans linked to the repo rate. However, investors should monitor shrinking systemic liquidity, which could increase borrowing costs for banks and impact their future profitability.
The Reserve Bank of India has increased the repo rate to 5.5 per cent, a move that is expected to reshape the profitability of the banking sector. The repo rate is the interest rate at which the central bank lends money to commercial banks. When this rate rises, banks typically increase their own lending rates.
Impact on Bank Margins
Analysts at IIFL Capital expect this rate hike to increase the net interest margin (NIM) for large banks by 6 to 10 basis points. NIM is essentially the difference between the interest income a bank earns from its loans and the interest it pays out to depositors. This expansion is likely because many banks have a significant portion of their loan books linked to the repo rate, allowing them to adjust interest rates for borrowers faster than they adjust interest rates for depositors.
Banks with a higher share of floating-rate loans—loans where the interest rate can change based on market conditions—are positioned to see these gains sooner. While this creates a positive short-term impact on earnings per share, the benefit depends on how effectively banks can manage the cost of funds.
Liquidity and Rising Costs
While rising rates can improve margins, they also coincide with a reduction in systemic liquidity. Data shows that banking system liquidity has tightened significantly, dropping from a peak of ₹11 trillion to ₹5 trillion. Liquidity refers to the cash available within the banking system to facilitate lending and day-to-day operations.
As this surplus cash decreases, market-based borrowing costs begin to climb. Indicators such as the weighted average call rate and yields on three-month certificates of deposit are expected to rise. When it costs banks more to borrow money from the market, their own profit margins could face pressure if they cannot fully pass these costs on to customers. Consequently, banks with a strong base of low-cost deposits, often referred to as CASA (Current Account Savings Account), are typically better protected during periods of tight liquidity.
Investor Monitorables
Investors tracking the banking sector should look beyond the headline margin expansion. While public sector banks and large private banks react differently to these policy changes, the primary monitorables remain the same. These include the bank's ability to maintain loan growth in a rising interest rate environment, the quality of their loan book, and how quickly they increase deposit rates to keep customers.
Rising interest rates are not purely positive; they carry the risk of slowing down loan demand if borrowing becomes too expensive for individuals and businesses. Additionally, if the cost of servicing loans increases, it could put pressure on the asset quality of lenders. Future updates from banks regarding their deposit growth and loan repricing strategy will provide a clearer picture of how these rate adjustments will ultimately affect bottom-line performance.
