1 Bank Interest Compounding (Anatocism)

What is Anatocism?

Anatocism is the generation of interest on interest that has already accrued and remains unpaid. When you fail to pay the interest owed to the bank, it gets "capitalized" and becomes the basis for calculating new interest. This practice can significantly inflate your debt over time.

Legal Framework

Art. 1283 c.c. - Allows anatocism only for liquid and due receivables overdue for at least six months and upon judicial request
CICR Resolution February 9, 2000 - Authorized anatocism in banking operations
Italian Supreme Court Ruling No. 25954/2023 - Declared quarterly capitalization of debit interest unlawful
Art. 120 TUB - Prohibited infra-annual capitalization (2014 Stability Law)

How to Identify Anatocism

Account balance grows without new operations
Frequent "overdrafts" even for small amounts
Very high interest rates on overdrafts
Interest systematically added to principal

Statute of Limitations

WARNING: Actions for anatocism have a 10-year statute of limitations for operations prior to 2010.

2 Banking Usury

Definition of Usury

According to Art. 644 of the Criminal Code and Art. 1815 of the Civil Code, a loan contract is usurious if it provides for interest rates that exceed, at the date of signing, the average rate published by the Bank of Italy, increased by half.

How to Calculate the Threshold Rate

EFFECTIVE RATE > AVERAGE RATE + (AVERAGE RATE × 50%) = USURY

Average rates are published at www.bancaditalia.it

Types of Usury

Manifest Usury

The nominal rate exceeds the threshold rate

Supervening Usury

The threshold is exceeded after signing

Latent Usury

The APR (all-inclusive) exceeds the threshold rate

Consequences of Usury

If the contract is usurious, the interest clause is VOID and interest is reduced to legal rates (significantly lower and calculated at the pro tempore legal rate).

2024 LAW UPDATE: In cases of supervening usury, the borrower has the right to reimbursement of interest exceeding the threshold rate and to recalculation of the amortization schedule.

3 Mortgages and Abusive Clauses

What Are Abusive Clauses?

Contract provisions that, in violation of the principle of good faith, determine a significant imbalance between the rights and obligations of the parties to the detriment of the consumer.

Most Common Abusive Clauses in Mortgages

Interest Rate Floor Clause

Limits the rate to a minimum even if market rates fall

High Early Repayment Fee

Excessive fees for loan prepayment

Hidden Investigation Fees

Loan processing fees not detailed or hidden

Unilateral Modification Clause

Allows bank to modify conditions at will

How to Identify Void Clauses

  • Clauses excluding bank liability
  • Clauses imposing obligations not provided by law
  • Clauses allowing unilateral changes without justification
  • Clauses excluding consumer's right of withdrawal

How to Proceed

  1. 1

    Precisely identify the illegitimate clause

  2. 2

    Verify if the bank has already applied the effects

  3. 3

    Calculate the amount to request for reimbursement

  4. 4

    Out-of-court claim → then judicial if necessary

4 Online Scams

Types of Scams

Phishing

Fake emails impersonating your bank

SIM Swapping

Scammer obtains a new SIM with your number

Banking Malware/Trojans

Software stealing credentials and OTP codes

Vishing

Calls where someone pretends to be your bank

Bank Liability Under PSD2

In case of unauthorized payment, the bank must immediately refund the amount, unless it proves that the customer acted with intent or gross negligence.

Landmark EU Court Ruling C-70/25

The bank must immediately refund in case of phishing, EVEN IF the customer acted with negligence. The burden of proof lies with the bank.

What to Do If You're a Victim

    Immediately contact your bank to block transactions

  2. 2

    Report to the Postal Police

  3. 3
