I am assuming you are talking about Karachi not Kiev Interbank Rate.
Karachi Interbank Offered Rate (KIBOR) is a daily reference rate based on the interest rates at which banks borrow unsecured funds from other banks in the Pakistan wholesale money market (or interbank market).
KIBOR is used for Forward rate agreements, interest rate swaps, inflation swaps and floating/syndicated loans.
I hope you got your answer, sorry if i am not able to use layman terms
