Summer is the season for financial triage. People open their wallets, check their balances, and try to figure out how to fund vacations without wrecking their monthly budgets. In the process, many look for ways to squeeze more yield out of their savings.
For years, there was a quiet loophole. Savers held multiple regulated savings accounts across different banks.
A Livret de développement durable et solidaire (LDDS) here. A Plan d’épargne en actions (PEA) there. Maybe a Livret d’épargne populaire (LEP) hidden in a credit union. It was a common practice. A well-kept secret among financially savvy individuals.
The law forbids it. French tax legislation clearly states that a private individual can only hold one version of these tax-advantaged accounts.
But enforcement was weak. Banks lacked the technology to cross-check databases. The system relied on trust. Specifically, on a self-declaration form you signed at the counter.
That era is ending.
The mechanics of the loophole
Opening a second regulated account used to be embarrassingly easy.
The rule is strict: one person, one account type. This protects public funds from being eroded by excessive tax exemptions.
The Livret A was the exception. Since 2013, its opening has been centralized. The system checks if you already hold one.
Other accounts? Not so much.
If you went to Bank A for a Livret jeune and then to Bank B for a Plan d’épargne logement (PEL), Bank B had no way to know Bank A existed. There was no national alert system. No cross-referencing engine.
The bank simply asked you to check a box. “I do not hold another account of this type.”
You checked it. You moved on.
This vulnerability allowed people to maximize deposit limits. With inflation eating away at purchasing power, stacking these accounts made sense. It was a way to shelter more money in tax-free or tax-reduced vehicles.
Consultants validated these files without raising flags. They couldn’t. They were flying blind.
The end of the blind spot
The silence breaks on July 1, 2027.
A new decree, the arrêté of June 2, 2026, changes the rules. It grants banks new powers.
From that date forward, the automatic verification system used for the Livret A will expand. It will cover the entire family of regulated savings products.
No more hiding. No more “I didn’t know.”
The technical inability to monitor accounts will vanish.
How Ficoba enforces the ban
The mechanism is simple and ruthless.
Banks will use the Ficoba. The national file of bank accounts.
This database is already familiar to tax authorities. Now, it becomes the gatekeeper for all regulated savings.
When you apply for a new account, the process changes.
- You submit your application.
- The bank automatically sends your identification data to the tax administration.
- The data includes your name, first name, date of birth, and place of birth.
- The system checks this against the centralized database in milliseconds.
If there is a match, the bank receives an immediate blocking alert.
The application is rejected before a teller ever sees your face.
Why this matters for your strategy
This shift kills the strategy of multi-detection.
If you have been relying on the gap in technological oversight, you have a deadline.
July 1, 2027, is the hard line.
Before then, if you open a new regulated account, you risk holding an illegal contract. You might not even know it until an audit occurs. Or worse, you might be penalized for tax fraud if the authorities decide to look back.
After July 2027, the risk changes.
You will be physically prevented from opening a duplicate. The bank’s system will stop you.
This means you must consolidate your savings.
If you have a LDDS at one bank and a LEP at another, you have a problem. You need to close one. Or keep one and accept the standard interest rate on the other.
There is no more gray area.
The tolerance for blind compliance is over. The infrastructure is being built to enforce the letter of the law.
For savers, this is a forced simplification.
It removes the complexity of managing fragmented portfolios across multiple institutions. It also removes the ability to game the system.
The question is no longer “How can I hide this account?”
The question is “Which single regulated account best fits my long-term goals?”
The era of easy loopholes is closing. The machinery is turning on. And it is only a matter of time before the grid snaps shut.
The net is tightening. If you have ever managed two of the same regulated savings account, you are now facing a deadline that cannot be ignored. The regulatory landscape has shifted from a period of tolerated ambiguity to a system of systematic detection. The message is blunt: regularization is not just advisable; it is mandatory.
When a bank flags a duplicate during a new account application, the account holder is backed into a corner. There are only two paths forward. The bank can handle the administrative burden to close the redundant account, but this requires explicit user consent. Alternatively, you have a strict two-month window to manually close the duplicate account at your other institution and provide formal proof of closure.
Miss that window. The sanction is immediate and automated. The new application is annulled and closed within fifteen days. No appeals. No grace period.
The specific targets of the crackdown
To understand the risk, you must identify which accounts are affected. The decree targets specific regulatory envelopes. If you hold more than one of the following across different banks, you are in violation:
- The Popular Savings Account (LEP)
- The Sustainable Development Savings Account (LDDS)
- The Equity Savings Plan (PEA)
- The Housing Savings Plan (PEL) and Housing Savings Account (CEL)
- The Youth Savings Account
The distinction here is critical. The legislation remains surprisingly flexible regarding wealth diversification and transmission vehicles. You are still permitted to hold multiple life insurance contracts (assurance-vie), multiple ordinary securities accounts (CTO), or several retirement savings plans (PER). This legal distinction allows for a degree of freedom in building a retirement portfolio, but it does not extend to the regulated savings products designed for primary financial protection.
The logic behind the single-account rule
Why now? The government’s intent is to clean up the benefits associated with regulated savings. These products often come with tax advantages or guaranteed interest rates. The state wants to ensure these incentives are concentrated on a single use per individual rather than being exploited through duplication. This legislative tightening forces a complete review of your precautionary savings distribution.
The message to the reader is clear. Use the remaining months before the full enforcement of these new controls to bring order to your holdings. Audit your accounts. Are you sure you don’t have a duplicate contract blocking your future financial moves? The system will find it. And when it does, you will be forced to choose: close it yourself, or let the bank do it for you.
