Borrowing at more than the exchange rate

Abstract

After explaining the details of this issue and researching it. It turns out the following: • The term exchange is related to the exchange of different currencies. • Conditions for the exchange contract: exchange, non-term and option, and symmetry if the currency is one. • Paper money has replaced gold and silver for the value considered in gold and silver, and money is considered as prices for the things that you do. • Lifting the gold and silver cover on paper and metal securities. • The issue that I discussed lost two conditions of the exchange contract, which are (exchange and non-term), so that contract was invalidated by losing its terms
