Non-Banking Financial Companies (NBFCs) do not have a fixed minimum lending rate; this is generally negotiable between the parties. However, the Reserve Bank of India (RBI) does announce an average base rate for NBFCs, which acts as a benchmark. For NBFC-Micro Finance Institutions (NBFC-MFIs), there's a maximum differential of 4% between the minimum and maximum interest rates on individual loans, and they must clearly display their lending rates.
