The issuer of credit to the debtor must not associate credit default only to the debtor because external risk could also lead to the default. In this case, debtor might not in be in capacity to pay debt installments to the creditor, and from this situation, the term “default” came from. Collateral was an element of credit to ensure that the issuance would be granted. If other elements supported the conviction about the capacity of debtor for debt settlement, then the collateral might take form as commodities, projects or collecting rights that could be financed by the related credit. Credit issued by the bank to the debtor customer was arranged based on trust and caution. These considerations were taken into account because credit always brought a risk, the default was possible (when debt was not paid and installments were stopped), the duty was not fulfilled, the deadline was passed, and provisions in credit agreement were not conducted. In this case, bank suffered from the loss.
