The Karachi Interbank Offered Rate (KIBOR) is the average interest rate at which banks lend to each other and serves as a benchmark for corporate lending in Pakistan. Calculated by the State Bank of Pakistan, it is derived from daily quotations of commercial banks, excluding the highest and lowest rates to ensure a market-driven rate. KIBOR encourages transparency in pricing, affects profit margins based on loan terms and bank liquidity, and is influenced by various economic factors.
