Executive Summary

Moving to Switzerland involves a major hurdle for expats: providing a rent guarantee (up to 3 months' rent according to Art. 257e CO) before receiving the keys. In 2026, with high average rents, this deposit often ranges between CHF 6,000 and 10,000. Two legal options exist: blocking the funds in a Swiss bank account in your name, or using a surety insurance (non-refundable). The real challenge for newcomers lies in transferring this capital from a foreign account (in Euros) to the Swiss guarantee account. To avoid abusive bank exchange fees, using an intermediary like ibani allows you to wire the funds directly to the guarantee account at the real exchange rate.

1. The Paradox of the Expat Tenant in 2026

You have finally found the ideal apartment in Geneva, Lausanne, or Zurich. The property management agency has accepted your application. But to get the keys, you must present the certificate proving that your rent guarantee has been established.

This is where what is commonly called "the expat paradox" comes in:

  1. To get the keys, you must fund the rent guarantee account in Switzerland.
  2. To open a Swiss checking account and transfer your funds, banks (subject to strict FINMA directives) often require your residence permit and an address... which you will only have after getting the keys.

The Legal Framework (Article 257e of the Code of Obligations)

It is crucial to understand Swiss legislation on this matter: you must never wire the deposit money directly into the landlord's or the agency's account. The law requires the funds to be deposited in a specific savings or deposit account, opened in your name. The maximum legal amount for a residential lease is set at three months' rent (excluding incidental charges).

2. Blocked Bank Account vs. Surety Company

To unblock the situation, the tenant has two options, each with a very different financial impact.

The Rent Guarantee Bank AccountThe Surety Company (e.g., SwissCaution)
Principle: You deposit the entire required amount (e.g., CHF 7,500) into a blocked bank account.Principle: An insurance company acts as a guarantor for you with the property management.
Long-term cost: Free. The capital still belongs to you. It will be returned to you (with slight interest) when you leave, minus any damages.Long-term cost: Very expensive. You pay an enrollment premium (e.g., CHF 231) then an annual premium (about 5% of the guarantee amount) which is non-refundable.
Constraint for the expat: Requires having a large amount of capital immediately and transferring it from abroad.Advantage for the expat: Preserves your liquidity during the move. However, in 2026, more and more deposits require the presentation of a B or C residence permit for final validation.

3. How to Fund Your Guarantee Account from Abroad Without Going Broke?

If you opt for the most financially rational solution (the blocked bank account), the property management agency will usually provide you with a form from the bank they work with (BCV, UBS, BCGE, Raiffeisen, etc.). Once this account is opened in your name, the bank will give you a Swiss IBAN number (starting with CH) to fund.

The Mistake of the International Bank Transfer

In 2026, with real estate inflation, a rent guarantee easily reaches CHF 6,000 to 10,000. If you make a direct transfer from your bank in France, Belgium, or Germany to this Swiss IBAN, your bank will apply an exchange margin (often between 1.5% and 2.5%) as well as SWIFT fees.

Result: on a transfer equivalent to CHF 8,000, you risk losing over 150 Euros in hidden fees.

The ibani Solution: Direct Transfer at the Interbank Rate

It is precisely to resolve this bottleneck linked to expatriation that ibani steps in. Our platform allows you to directly fund your Swiss guarantee account from your euros, without opening a Swiss checking account beforehand.

  • Step 1: You open an ibani account (100% online, quick validation with your European ID).
  • Step 2: You enter the IBAN of your Swiss rent guarantee account in the application as a beneficiary.
  • Step 3: You transfer your Euros to the ibani account. We convert them at the real interbank rate (with a minimal and transparent margin) and instantly transfer the CHF to your guarantee account.

The Swiss bank then issues the deposit certificate, you hand it over to the agency, and you get your keys.

Frequently Asked Questions (Swiss Security Deposit)

According to Article 257e of the Swiss Code of Obligations (CO), for residential leases, the landlord cannot require security deposits exceeding three months' rent (excluding incidental charges).

Absolutely not. Swiss law stipulates that the rent guarantee must be deposited in a blocked savings or deposit bank account, opened in the tenant's name. The landlord is not allowed to keep these funds in their own account.

To avoid SWIFT fees and traditional bank exchange margins on a large sum (often exceeding CHF 6,000), it is recommended to use a Swiss financial intermediary like ibani. You can transfer your euros, which will be converted at the interbank rate and sent directly to the rent guarantee account's IBAN.

It is an alternative to blocking funds. An insurance company acts as a guarantor for you with the landlord. In return, you do not block any capital, but you pay an annual non-refundable premium (generally around 5% of the guarantee amount).
