Evolution of RBI's Lending Rate Benchmarks -  From Prime Lending Rate to External Benchmark System (1994-2019)

The landscape of banking interest rates in India has undergone fundamental transformations over the past three decades, directly impacting millions of borrowers across retail, corporate, and MSME segments. This comprehensive article chronicles the evolution of the Reserve Bank of India's lending rate frameworks from 1994 to the present, tracing the journey from the Prime Lending Rate (PLR) system through to today's External Benchmark-based Lending Rate (EBLR) regime.

For borrowers who have availed floating rate loans—whether home loans, personal loans, auto loans, or business credit—understanding these regulatory changes is crucial. Your loan's interest rate mechanism, reset frequency, and the basis for rate adjustments are all governed by the specific regime under which your loan was sanctioned. A home loan taken in 2008 operates under different rules than one taken in 2015 or 2020, affecting how quickly you benefit from RBI's policy rate cuts or bear the impact of rate hikes.
