Marginal Cost of Funds Based Lending Rate (MCLR)

The Marginal Cost of Funds Based Lending Rate (MCLR) is an internal benchmark lending-rate regime that the Reserve Bank of India (RBI) introduced through a circular dated 17 December 2015, made operative from 1 April 2016. It superseded the Base Rate system that had governed bank lending since July 2010, which in turn had replaced the Benchmark Prime Lending Rate (BPLR) of 2003. The legal basis flows from the RBI's powers under the Banking Regulation Act, 1949, and the Reserve Bank of India Act, 1934, which authorise the central bank to issue directions on interest rates charged by scheduled commercial banks. The reform responded to a recurring complaint by the RBI's Monetary Policy Department: under the Base Rate, banks transmitted repo-rate cuts to borrowers slowly and incompletely, because the Base Rate was computed on the average cost of existing deposits rather than the cost of fresh funds. The MCLR was designed to make lending rates more sensitive to policy-rate changes by anchoring them to the marginal cost of funds.

Mechanically, the MCLR is the sum of four components. The first and largest is the marginal cost of funds, itself a weighted composite of the marginal cost of borrowings (given a 92 percent weight) and the return on net worth (8 percent). The marginal cost of borrowings reflects the interest rates a bank pays on its latest tranche of deposits and other liabilities across maturities, weighted by their outstanding balances. The second component is the negative carry on the Cash Reserve Ratio (CRR), which compensates the bank for the un-remunerated balances it must park with the RBI. The third is operating costs—the expense of raising funds and running loan operations, excluding costs recovered through separate service charges. The fourth is the tenor premium, an add-on reflecting the higher risk of longer-duration commitments. Banks publish MCLRs for several maturities—overnight, one-month, three-month, six-month, and one-year being standard—and review them at least once a month on a pre-announced date.

The actual rate charged to a borrower is the MCLR of the relevant tenor plus a spread. The spread has two parts: a business-strategy component and a credit-risk premium that varies with the borrower's rating and the loan's risk profile. Once a floating-rate loan is linked to a particular MCLR tenor, the contract specifies a reset date—at intervals not exceeding one year—on which the applicable rate is realigned to the prevailing MCLR. Between reset dates the rate stays fixed even if the bank revises its MCLR, which creates a transmission lag. Fixed-rate loans of tenor up to three years are also priced with reference to the MCLR, whereas longer fixed-rate loans and certain categories—loans against deposits, loans to a bank's own employees, and fixed-rate loans above three years—are exempt from the MCLR framework.

In practice the MCLR became the dominant pricing benchmark for corporate and personal lending between 2016 and 2019. The State Bank of India, India's largest lender, anchored most of its term loans to its one-year MCLR, and home-loan rates across HDFC Bank, ICICI Bank, and public-sector banks moved with it. The RBI's own Internal Study Group on the working of the marginal cost system, chaired by Janak Raj and reporting in October 2017, concluded that transmission remained inadequate even under the MCLR, partly because banks manipulated the spread and the reset clauses. That finding drove the RBI's next reform: from 1 October 2019 banks were directed to link all new floating-rate loans to retail and micro-and-small-enterprise borrowers to an external benchmark.

The MCLR must be distinguished from the External Benchmark Lending Rate (EBLR), which now coexists with it. EBLR ties the loan rate to an external reference—usually the RBI repo rate, or a Treasury-bill yield published by Financial Benchmarks India Pvt. Ltd.—rather than to the bank's internal cost of funds, and it resets at least quarterly, producing faster and fuller transmission. The MCLR also differs from the older Base Rate, which used average rather than marginal funding costs, and from the BPLR, which was opaque and allowed sub-BPLR lending to favoured clients. A loan's pricing today therefore depends on its vintage: legacy borrowers may still sit on Base Rate or BPLR loans, mid-period borrowers on MCLR, and post-2019 retail borrowers on EBLR.

Controversy has centred on incomplete transmission and on borrowers stranded on higher legacy benchmarks. Because EBLR transmits repo cuts almost immediately while MCLR lags, MCLR borrowers during the easing cycle of 2019–2021 frequently paid more than EBLR borrowers of identical risk, prompting the RBI to permit—and effectively encourage—conversion to the external benchmark on payment of a switching fee. The RBI has periodically tightened disclosure norms and, through its Monetary Policy Reports, has tracked the weighted-average lending rate on outstanding versus fresh rupee loans to gauge transmission. MCLR-linked stock nonetheless remains a substantial share of bank loan books, especially in corporate lending, which lies outside the mandatory EBLR regime.

For the working practitioner—whether a UPSC aspirant analysing monetary-policy transmission for General Studies Paper III, a banking-sector analyst, or a financial journalist—the MCLR is the conceptual bridge between the RBI's policy rate and the cost of credit in the real economy. It illustrates why central-bank rate changes do not pass through to borrowers instantly, why India moved toward external benchmarks, and why the structure of bank funding costs matters for growth and inflation management. Understanding its four components and its reset mechanics is essential to interpreting any debate on monetary-policy effectiveness in India.
