HDFC Bank and ICICI Bank have both hiked up lending rates by about 50 bps, says ET. This takes ICICI's base rate to 8.25% and HDFC Bank's base rate to 8.2%. Banks can't lend below the base rate. Most existing customer loans are linked to a "Benchmark Prime Lending Rate" (BPLR) which has also been raised appropriately.
