The Fiduciary Duty of Banks in Loan Accounting: A Guide to Metrobank v. Cruz

Metropolitan Bank and Trust Company v. Carmelita Cruz and Vilma Low Tay (G.R. No. 221220, January 19, 2021) is a clear reminder that a bank’s duty to its clients goes far beyond collecting payments. The Supreme Court affirmed that banks must treat client accounts with the highest degree of care and fidelity, and that internal document retention policies cannot excuse a failure to render a complete accounting.

The Facts of the Case

From 1993 to 1998, Carmelita Cruz and Vilma Low Tay obtained loans from Metrobank totaling P40.6 million, covered by promissory notes. They took out additional loans in 1999 and requested a statement of account. Metrobank reported that as of March 26, 1999, they owed P1,130,444.31.

Over the years, the loans were restructured, and the borrowers were made to sign blank promissory notes in bulk. Between 1999 and 2004, Cruz and Tay made cash and check payments. Cruz kept her own records on yellow sheets and asked bank employees to acknowledge receipt of each payment.

In 2004, the borrowers reviewed their records and believed they had overpaid. Metrobank’s Summary on Application of Payments showed an outstanding balance of P8,344,185.55, but an independent accountant found that Metrobank had failed to record P12,140,519.55 in payments. The accountant concluded that the borrowers had actually overpaid by P3,540,519.55.

Metrobank refused to provide a complete accounting, so the borrowers filed a complaint for accounting in 2005.

The Issue

The central question was whether Metrobank should be ordered to render a full and detailed accounting of the borrowers’ payments and to furnish all pertinent loan documents.

Metrobank argued that it had already provided accurate statements, that producing documents from as far back as 1993 was impossible due to its five-year retention policy, and that the borrowers were estopped from questioning their debt because they signed subsequent promissory notes acknowledging the amounts owed.

The Ruling: Fiduciary Duty Prevails

The Supreme Court denied Metrobank’s petition and affirmed the lower courts’ orders.

The Court cited Section 2 of the Banking Law (Republic Act No. 8791), which recognizes the fiduciary nature of banking and requires high standards of integrity and performance. Although that law took effect in 2000, the Court noted that jurisprudence had already imposed the same high standard of diligence on banks since at least 1990, citing the landmark case Simex International (Manila) Inc. v. Court of Appeals.

The Court emphasized two essential obligations of banks: to treat clients’ accounts with utmost fidelity and meticulous care, and to record all transactions accurately and promptly. It also cited Far East Bank and Trust Co. v. Tentmakers Group, Inc., which held that the diligence required of banks is more than that of a good father of a family — the highest degree of diligence is expected.

The Five-Year Retention Policy Defense Fails

Metrobank argued that its five-year retention policy, supposedly aligned with the Anti-Money Laundering Act and the Manual of Regulations for Banks, made it impossible to produce documents from 1993.

The Court rejected this defense. Those laws require record retention for five years for purposes of detecting money laundering — they do not excuse a bank from its fiduciary duty to maintain accurate records of an existing loan. The documents requested were essential to the borrowers’ existing loan, and the accuracy of the outstanding obligation depended on a complete computation of previous loans.

Moreover, the Court found that production was not actually impossible. Metrobank’s own employee admitted that paper documents were stored in a warehouse, and that only computer records were deleted. Metrobank had also produced documents from 1993 to 1998 in 2007 — records that were 14 years old, well beyond its alleged five-year policy.

Estoppel Cannot Be Used for Injustice

The Court also rejected Metrobank’s estoppel defense. The borrowers were made to sign blank promissory notes in bulk, and they immediately requested a statement of account to verify their outstanding balance. There was no silence or inaction that misled the bank. The Court stressed that estoppel should not be used as a tool for injustice or as an excuse to escape the obligation to render a proper accounting.

Practical Takeaways

• Banks owe clients the highest degree of diligence. This is not just a moral expectation — it is a legal obligation rooted in the fiduciary nature of banking under R.A. No. 8791 and longstanding jurisprudence.
• Internal retention policies do not override fiduciary duties. A bank cannot hide behind a five-year document retention policy when a client needs records essential to an existing loan. The duty to maintain accurate records prevails.
• Borrowers should keep their own payment records. In this case, the borrowers’ yellow sheets and acknowledged receipts were crucial evidence. Keeping organized records of every payment, with signed acknowledgments, protects borrowers in disputes.
• Estoppel has limits. A borrower who signs a promissory note is not automatically barred from questioning the balance, especially if the borrower was made to sign blank notes or promptly raised discrepancies upon discovery.
• Seek legal help early. If a bank fails to provide a complete statement of account or there are unexplained discrepancies, consult a lawyer promptly. Delays can complicate the recovery of records and evidence.
