Abstract

A host apparatus of a financial auction system is disposed in a site that is accessible from user terminal apparatuses through the transmission line of a network. The host apparatus has a borrowing agent serving as the window for a potential borrower, a lending agent serving as the window for a potential lender, a screening section for extracting a potential lending offer matching a predetermined condition, a matchmaking section for selecting a successful bid from potential lending offers, and an information collection section for collecting background information of a potential borrowing request. A database is attached to the host apparatus, where a borrowing request file, lending offer file, and background information file are formed.

a section configured to input a plurality of potential lending offers each including a desired lending amount and a desired lending interest; and

a section configured to perform matching between the potential borrowing requests and the potential lending offers on the basis of the respective maximum allowable interests and desired lending interests and to make the desired lending amount of a potential lending offer extracted as a result of matching correspond to the desired borrowing amount of a potential borrowing request extracted as a result of matching.

9. The system according to

claim 1

, further comprising:

a repayment totalizing section configured to calculate a total repayment amount for each repayment maturity of a single borrower; and
