Interest rates play a central role in shaping India’s economy—affecting everything from how much people pay on home loans to how businesses finance their operations. The Reserve Bank of India (RBI) is the primary authority responsible for regulating interest rates, ensuring that they support both economic growth and financial stability.
Role of the RBI in Interest Rate Regulation
The RBI regulates interest rates mainly through its Monetary Policy Committee (MPC). Established in 2016, the MPC meets regularly to decide key policy rates, such as:
* Repo Rate: The rate at which banks borrow from the RBI.
* Reverse Repo Rate: The rate at which banks park their surplus funds with the RBI.
However, SDF is the new floor for policy rates introduced by RBI in April 2022, as a mechanism to curb inflation by absorbing liquidity. The SDF rate is applied for which banks park their excess funds with the RBI without any collateral. Although, earlier system of reverse repo rate will remain as part of RBI’s toolkit and its operation will be at the discretion of the RBI for purposes specified from time to time, according to RBI’s announcement. This move of RBI makes the reverse repo rate redundant for now.
Changes in these rates influence the cost of borrowing and lending across the financial system. The RBI Governor holds the casting vote in case of a tie among MPC members.
Influence on Banking and Lending Rates
Banks in India align their loan and deposit rates with the RBI’s benchmark policy rates. For example:
* When the repo rate is reduced, banks can borrow more cheaply, which usually lowers lending rates for consumers and businesses.
* When the reverse repo rate increases, banks are incentivized to deposit more funds with the RBI, tightening liquidity in the system.
This mechanism helps the RBI control inflation, stimulate growth, or maintain stability depending on the economic situation.
Regulation of Deposit Rates
Over the years, interest rates on deposits have been largely deregulated; giving banks more freedom in setting them. However, some rules remain:
* Savings Accounts: Banks must offer a uniform rate up to ₹1 lakh.
* Term Deposits: Flexibility exists, though RBI may prescribe guidelines.
* Non-Resident Deposits: Rates cannot exceed comparable domestic deposit rates, keeping them competitive but fair.
NBFCs and Interest Rate Regulation
Non-Banking Financial Companies (NBFCs) do not have their lending rates directly regulated by the RBI. Instead, the RBI enforces a Fair Practice Code, ensuring:
* Charges remain reasonable.
* Excessive or exploitative rates can attract penalties.
This indirect regulation protects consumers, particularly in high-risk lending segments where NBFCs are active.
Policy Rate Cycles and Economic Impact
RBI frequently adjusts policy rates based on inflation, growth, and liquidity needs.
📌 Example: In April 2025, the repo rate was cut to 6.00% to stimulate growth amidst softening inflation. Such decisions affect:
* Home loans and car loans → EMIs reduce when rates fall.
* Corporate borrowing → Lower costs encourage businesses to invest.
* Consumer spending → Cheaper credit boosts demand in the economy.
Minimum Lending Rates and Base Rate System
The base rate system was an interest rate mechanism introduced in India by the Reserve Bank of India (RBI) in July 2010, setting a minimum lending rate for banks and requiring them to declare it to enhance loan pricing transparency. While it replaced the older Benchmark Prime Lending Rate (BPLR) system, it had limited effectiveness in transmitting monetary policy changes and was eventually replaced by the Marginal Cost of Funds-based Lending Rate (MCLR) in 2016 and the External Benchmark-based Lending Rate (EBLR). While important; the Base Rate has largely been replaced by the MCLR (Marginal Cost of Funds-based Lending Rate) for new loans, which offers a more market-driven approach to borrowing. The Marginal Cost of Funds Based Lending Rate (MCLR) is a benchmark rate set by Indian banks to determine the minimum interest rate they can charge for loans. It is based on the bank’s incremental or marginal cost of raising funds, rather than the average cost, and includes components like the marginal cost of funds, tenor premium, operating costs, and the negative carry on the mandatory Cash Reserve Ratio (CRR). MCLR is an internal reference rate that influences the interest rates for various loan products. While new loans are no longer linked to the base rate, loans sanctioned before April 1, 2016, may still be on the base rate system.
Key Aspects of MCLR
Internal Benchmark:
Banks use MCLR as an internal benchmark to calculate the lowest possible interest rate for loans they offer. To maintain fairness and transparency, the RBI introduced the EBLR system. Banks cannot lend below this minimum rate, which:
* Prevents arbitrary or discriminatory pricing of loans.
* Promotes uniformity across the banking sector.
* Protects customer interests by ensuring transparency in lending practices.
External Benchmark-based Lending Rate (EBLR)
The External Benchmark-based Lending Rate (EBLR) is a reference interest rate, primarily the Reserve Bank of India (RBI) repo rate, that links a bank’s floating rate loan interest to an external market rate, ensuring more transparency and faster transmission of the central bank’s monetary policy decisions to borrowers. Under this system, a borrower’s loan rate is calculated as the EBLR plus a spread, which represents the bank’s profit margin and risk. This replaced the previous Marginal Cost of Funds-Based Lending Rate (MCLR) system, which often delayed the impact of rate changes on loan interest.The EBLR is based on an external factor like the repo rate, 91-day or 182-day treasury bills, or other RBI-approved benchmarks.
Conclusion
The regulation of interest rates in India is a dynamic and carefully balanced process led by the RBI. Through policy rates, regulatory frameworks, and constant supervision, the central bank ensures that interest rates serve the dual goals of economic growth and financial stability.
✅ Key Takeaways
* The RBI regulates interest rates mainly through repo and reverse repo rates, set by the **Monetary Policy Committee (MPC) **.
* Banks link their loan and deposit rates to RBI’s benchmarks, ensuring alignment with monetary policy.
* Deposit rates are mostly deregulated, but with some safeguards like uniform savings rates.
* NBFCs follow the RBI’s Fair Practice Code instead of direct rate regulation.
* Policy rate changes, like the April 2025 repo rate cut, directly impact EMIs, corporate borrowing, and overall demand.
* The EBLR Rate system prevents unfair lending practices and ensures transparency.
