Marginal Cost of Funds based Lending Rate (MCLR)

The Marginal Cost of Funds based Lending Rate (MCLR) is the internal benchmark interest rate methodology that the Reserve Bank of India (RBI) mandated for scheduled commercial banks through its circular dated 17 December 2015, effective for all rupee loans sanctioned and credit limits renewed from 1 April 2016. It was introduced under the RBI's powers to regulate the credit system under the Banking Regulation Act, 1949 and the Reserve Bank of India Act, 1934, and it superseded the Base Rate system that had operated since July 2010 and the Benchmark Prime Lending Rate (BPLR) regime before it. The animating concern was poor monetary transmission: when the RBI cut the repo rate, banks under the Base Rate system, which relied on the average cost of funds, were slow to pass reductions to borrowers. By anchoring lending to the marginal—incremental—cost of raising new deposits and borrowings, the RBI sought to make lending rates more responsive to policy-rate changes.

Mechanically, the MCLR is the sum of four components. The first and dominant is the marginal cost of funds, itself a weighted figure combining the marginal cost of borrowings (given a 92 percent weight) and the return on net worth (given an 8 percent weight, reflecting the cost of equity capital prescribed by Tier I norms). The marginal cost of borrowings is computed from the latest rates at which the bank raises deposits across maturities, savings and current account balances, and other borrowings, weighted by their outstanding shares. The second component is the negative carry on the Cash Reserve Ratio (CRR), which arises because banks earn no interest on balances impounded with the RBI, raising the effective cost of deployable funds. The third is operating costs associated with raising funds and extending loans, excluding charges recovered separately. The fourth is the tenor premium, which compensates the bank for the higher risk inherent in longer-duration commitments.

Banks must publish MCLR for several maturities—overnight, one month, three months, six months, and one year, at minimum—and review and publish them on a pre-announced date every month. The actual rate charged to a borrower equals the MCLR of the relevant tenor plus a spread, which itself comprises a business-strategy component and a credit-risk premium specific to the borrower. Loans are reset at intervals not exceeding one year, so a borrower's rate is fixed until the contractual reset date even if the published MCLR moves earlier. Fixed-rate loans of tenor up to three years and certain categories—loans against deposits, loans to bank employees, and government-scheme loans where rates are prescribed—are exempt from the MCLR framework.

In contemporary practice, the State Bank of India, the country's largest lender headquartered in Mumbai, publishes its MCLR schedule monthly, and movements in SBI's one-year MCLR are closely tracked as a market signal. During the RBI's accommodative cycle through 2019 and 2020, the central bank repeatedly observed that transmission under MCLR remained incomplete, prompting it to mandate, via a circular dated 4 September 2019, that banks link all new floating-rate retail and MSME loans to an external benchmark—most commonly the repo rate—from 1 October 2019. This created a parallel regime: legacy and many corporate loans continue under MCLR, while new home, auto, and small-business loans largely sit under the External Benchmark Lending Rate (EBLR).

The MCLR must be distinguished from the Base Rate, which it replaced and which used average rather than marginal funding cost; from the repo rate, which is the RBI's policy rate at which it lends to banks and which feeds into but is not identical to MCLR; and from the External Benchmark Lending Rate (EBLR), under which the lending rate is tied directly to an external reference such as the repo rate or a Treasury-bill yield, with resets at least every three months and far more immediate transmission. Whereas MCLR is an internal benchmark computed from each bank's own cost structure, EBLR removes that discretion by pegging rates to a publicly observable external anchor.

The principal controversy surrounding MCLR has been the persistence of sluggish transmission and the asymmetry borrowers perceived: lenders appeared quicker to raise MCLR when funding costs rose than to lower it when the repo rate fell. The annual reset cycle meant a borrower could wait up to twelve months to benefit from a rate cut. An RBI internal study group chaired by Janak Raj, whose report was released in October 2017, found that internal-benchmark systems including MCLR had failed to deliver effective transmission and recommended the external-benchmark approach that the RBI subsequently adopted. Despite these limitations, MCLR was not abolished; a large stock of corporate and pre-October-2019 loans remains tied to it, and banks continue to compute and publish it.

For the working practitioner—whether a UPSC aspirant preparing GS Paper III, a banking-sector analyst, or a policy researcher—the MCLR is essential to understanding the architecture of Indian monetary transmission and why the RBI moved successively from BPLR to Base Rate to MCLR to EBLR in pursuit of faster, fuller pass-through of policy signals. It illustrates the structural friction between a central bank's policy rate and the rates households and firms actually face, the role of CRR and deposit composition in bank pricing, and the regulatory trade-off between leaving banks discretion over internal benchmarks and forcing transparency through external ones. Comprehending this evolution is indispensable for analysing credit conditions, transmission lags, and the effectiveness of contemporary Indian monetary policy.
