Unconscionable Interest Rates When Loan Agreements Become Exploitative

The Supreme Court has long given lenders and borrowers the freedom to agree on interest rates. But that freedom has limits. When a stipulated interest rate becomes so excessive that it shocks the conscience, the Court will step in and reduce it. The case of Cuaton v. Salud (G.R. No. 158382, January 27, 2004) illustrates exactly when a loan agreement crosses the line from lawful to exploitative.

The Facts of the Case

In October 1991, Mansueto Cuaton obtained a one-million-peso loan from Rebecca Salud. The loan was secured by a real estate mortgage over a property titled in the name of Cuaton's mother, Conchita. When the parties fell into dispute, Salud filed a suit to foreclose the mortgage.

The trial court declared the mortgage void because Cuaton had not expressly stated that he was acting as his mother's representative. However, the court still ordered Cuaton to pay the original loan plus P610,000.00 in interest — computed at rates of 10% per month for several months and 8% per month for others.

The Court of Appeals affirmed this ruling. Cuaton then elevated the case to the Supreme Court, arguing that the monthly interest rates were iniquitous and exorbitant.

The Sole Issue

The only question before the Supreme Court was whether interest rates of 8% and 10% per month on the one-million-peso loan were valid.

The Ruling: Excessive Rates Are Unconscionable

The Supreme Court ruled in favor of Cuaton, reducing the interest rates to 12% per annum.

The Court acknowledged that the Usury Law had been suspended by Central Bank Circular No. 905 (effective January 1, 1983), which gave parties wide latitude to agree on any interest rate. However, the Court was emphatic: nothing in that Circular grants lenders carte blanche authority to raise interest rates to levels that would "enslave their borrowers or lead to a hemorrhaging of their assets." Stipulated interest rates are illegal if they are unconscionable.

The Court cited its earlier rulings in Medel v. Court of Appeals and Spouses Solangon v. Salazar, where it annulled interest rates of 5.5% per month (66% per annum) and 6% per month (72% per annum), respectively, for being excessive. In both cases, the rates were reduced to 12% per annum.

The rates in Cuaton — 10% and 8% per month, or 120% and 96% per annum — were even higher than those previously invalidated. The Court therefore found the reduction to 12% per annum fair and reasonable.

The Legal Basis: Article 1409 of the Civil Code

The Court grounded its ruling on Article 1409 of the Civil Code, which provides that contracts whose cause, object, or purpose is contrary to law, morals, good customs, public order, or public policy are inexistent and void from the beginning. Stipulations authorizing iniquitous or unconscionable interests are contrary to morals (contra bonos mores), if not against the law itself.

Such contracts cannot be ratified, and the right to set up their illegality as a defense cannot be waived.

Interest Computation After the Ruling

Applying the guidelines from Eastern Shipping Lines, Inc. v. Court of Appeals, the Court ruled that the 12% per annum interest should be computed from the date of the loan's execution on October 31, 1991, until the finality of the decision. After the judgment becomes final and executory, the amount due shall further earn interest at 12% per year until fully satisfied.

Practical Takeaways

• Interest rates are not unlimited. Even after the suspension of the Usury Law, courts will strike down interest rates that are unconscionable, excessive, or iniquitous.
• Monthly rates above 5-6% are highly vulnerable. The Supreme Court has consistently invalidated rates of 5.5% to 10% per month and reduced them to 12% per annum.
• The defense of unconscionability is strong. A borrower can raise this defense even if the issue was not squarely assigned as an error on appeal, as long as it was raised before the trial court.
• Article 1409 applies. Loan agreements with unconscionable interest stipulations are void from the beginning and cannot be ratified.
• Expect 12% per annum as the benchmark. When courts reduce unconscionable rates, they typically apply the legal interest rate of 12% per annum, computed from default or demand until finality of judgment, and continuing at the same rate until satisfaction.
