"fter delivery of the thing borrowed to the borrower, the creditor does not have any obligations. In instances where the creditor failed to fully release the loan amount, the SC has characteri1ed the loan as a bilateral contract that imposes reciprocal obligations on the parties. 0he SC held that the creditor has the obligation to release the full amount of the loan and the debtor has the obligation to pay the loan when it becomes due and demandable.

If the agreement is silent on the currency, then payment must be made in the currency in which the money was delivered, based on the principle that borrower must pay “the same amount of the same kind and quality. If it is not possible to deliver in the relevant currency, payment must be made in the currency which is legal tender in the 4hilippines. 0he amount payable may change under certain circumstances, such as when there is e)traordinary in5ation or de5ation of the currency stipulated.
