The supreme court of the United Arab Emirates has issued a ruling that changes the rules for every bank in the country. Financial institutions can no longer charge interest on already-accumulated interest. It sounds technical, but in practice it means that a borrower’s debt can no longer grow exponentially due to the capitalization of unpaid interest. This topic has already echoed across Business Bay real estate news, as lenders reassess how they finance commercial property purchases after the ruling.
The case began with two loans taken by one borrower: a commercial loan of 634,000 dirhams at 11.25 percent and a consumer loan of 66,000 dirhams at 10.5 percent, totalling 700,000 dirhams. When the borrower stopped paying, the bank filed a claim for 1.919 million dirhams plus ongoing interest. The bank’s name was not disclosed.
A court expert calculated the debt in two ways. The simple method showed: the borrower withdrew 700,000, repaid 50,214, leaving 649,786 in principal. Accrued interest at the time of the last payment reached 40,967.28. The total was 690,753.28 dirhams.
The second method used compound interest, in which unpaid interest is added to the principal and then earns more interest. In this model, interest ballooned to 860,147.88 dirhams plus a 43,170 penalty. The total reached 1,553,103.88 dirhams — more than double the original loan.

The appellate court chose the higher amount, but the supreme court intervened
The appellate court sided with the bank, but the borrower appealed. The Supreme Court overturned the ruling, noting that a debt exceeding the loan amount by more than twice the loan amount clearly violates the law.
The court referred to article 121 of federal decree-law no. 23 of 2022, amending decree-law no. 14 of 2018. The rule is direct: licensed financial institutions cannot charge interest on accumulated interest. No exceptions.
Matthew Escritt from the Dubai office of Pinsent Masons explains that creditors must now ensure complete transparency of loan terms. Borrowers receive meaningful protection against excessive interest charges, especially when financial difficulties lead to missed payments. Many Business Bay real estate news updates mention how banks have already started adjusting their lending models in this district.
Seya Rahnema, also a financial law specialist at the firm, adds that institutions must revise credit policies and interest calculation methodologies. This primarily affects consumer lending, where banks traditionally capitalized unpaid interest every month. Now such practice is illegal.
Commercial loans will feel less impact, because interest is usually kept separate from principal. Even so, banks must review their calculation systems to ensure there is no hidden capitalization. And even everyday financial planning questions — like how much does home maintenance cost in Dubai and UAE in general? — may now include checking mortgage terms for any compound-interest traps buried in the fine print.
Banks will have to rebuild accounting systems and revise thousands of contracts
The practical consequences go far beyond a single case. Banks must now:
- audit all active loan agreements for any form of interest capitalization
- recalculate borrower debts where compound interest was applied
- update software to eliminate automatic capitalization
- rewrite loan agreement templates with clear interest-calculation rules
- train staff to understand and apply the new requirements
For borrowers, the changes mean:
- the right to review existing contracts if capitalization was used
- the ability to challenge a bank’s calculations in court with reference to the supreme court ruling
- greater transparency in new loan agreements, since banks must clarify their methods

The supreme court’s decision sets a precedent for the entire UAE legal system: any borrower can now challenge a bank’s claim if there are signs of interest-on-interest. Lower courts must follow the supreme court’s stance.
The UAE banking sector is undergoing a period of regulatory tightening, with authorities prioritizing transparency and client protection. Banks that ignored the law and continued capitalizing interest now risk a wave of lawsuits. The transition period will be painful: revising thousands of agreements, recalibrating IT systems, and dealing with potential disputes will take time and money. But there is no alternative. The supreme court has drawn a clear line, and challenging it is pointless.
