Abstract: The present invention is a system, method, and resultant financial for enabling a transparent estimation of an inter-bank offered interest rate which is dependent on market participant's estimations of current lending and borrowing rates. The improved functionality arises through inclusion of both estimated borrowing rates and estimated lending rates to determine a mean inter-bank offered rate. The process implements panel observers, and exception criteria, to preclude determinations biased by skewed estimates provided by panel members and or panel participants. The improved process and system of the present invention further allows implementation of creditworthiness adjustments to inter-bank offered rates based on the creditworthiness of the panel participants, as well as implementation of obligated transactions as a means for dissuading panel members and/or panel participants from submitting biased estimates.
