The contract between the bank and its depositor is governed by the provisions of the Civil Code on simple loan. Article 1980 of the Civil Code expressly provides that “x x x savings x x x deposits of money in banks and similar institutions shall be governed by the provisions concerning simple loan.” There is a debtor-creditor relationship between the bank and its depositor. The bank is the debtor and the depositor is the creditor. The depositor lends the bank money and the bank agrees to pay the depositor on demand. The savings deposit agreement between the bank and the depositor is the contract that determines the rights and obligations of the parties.
The law imposes on banks high standards in view of the fiduciary nature of banking. Section 2 of Republic Act No. 8791 (“RA 8791”), which took effect on 13 June 2000, declares that the State recognizes the “fiduciary nature of banking that requires high standards of integrity and performance.” This new provision in the general banking law, introduced in 2000, is a statutory affirmation of Supreme Court decisions, starting with the 1990 case of Simex International vs. Court of Appeals, holding that “the bank is under obligation to treat the accounts of its depositors with meticulous care, always having in mind the fiduciary nature of their relationship.”
This fiduciary relationship means that the bank’s obligation to observe “high standards of integrity and performance” is deemed written into every deposit agreement between a bank and its depositor. The fiduciary nature of banking requires banks to assume a degree of diligence higher than that of a good father of a family. Article 1172 of the Civil Code states that the degree of diligence required of an obligor is that prescribed by law or contract, and absent such stipulation then the diligence of a good father of a family. Section 2 of RA 8791 prescribes the statutory diligence required from banks – that banks must observe “high standards of integrity and performance” in servicing their depositors.
