Bank guarantees explained: what they are, how they work and when they are required in Portugal.

 

• Bank guarantees are widely used financial instruments in Portugal, offering security in transactions such as real estate, construction and commercial contracts.
• They protect beneficiaries against non-compliance by ensuring that a bank assumes financial responsibility if contractual obligations are not met.
• In this article, we explain what bank guarantees are, how they work in practice, the most common types used in Portugal and what to consider before requesting or accepting one.

 

When large sums of money are at stake, trust alone is rarely enough. In Portugal, bank guarantees are a cornerstone of complex financial transactions, providing reassurance where risk, timelines, and obligations intersect. From real estate developments and construction contracts to leasing agreements and investment operations, these guarantees act as a critical safety net for investors, developers, and individuals alike.

In this article, we break down how bank guarantees work in Portugal, the most common types you’re likely to encounter, and the key factors to consider before requesting or accepting one—so you can move forward with confidence, not uncertainty.

 

What are bank guarantees?

A bank guarantee is a commitment issued by a financial institution in which the bank undertakes to pay a specified amount to a beneficiary if the applicant fails to meet their contractual obligations.

In simple terms, the bank replaces the risk of non-performance by the applicant with its own creditworthiness, providing reassurance to the beneficiary that the agreed conditions will be fulfilled or compensated.

Bank guarantees are governed by contractual terms and Portuguese banking regulations, and they are widely recognised as a reliable risk mitigation tool. They involve three main parties:

• Applicant: the party requesting the guarantee (e.g. buyer, developer or tenant);
• Beneficiary: the party protected by the guarantee;
• Bank: the institution issuing the guarantee and assuming the financial obligation.

 

If the applicant complies with the contract, the guarantee expires without any payment being made. If the applicant defaults, the beneficiary may call the guarantee and request payment under the conditions defined in the document. The bank will then assess whether the conditions for execution have been met and, if so, make the payment up to the guaranteed amount.

 

Benefits of bank guarantees in real estate

Bank guarantees serve as a vital pillar of security in the Portuguese property market, offering essential safeguards for all parties involved in a transaction.

 

1. Enhanced protection for your investment

Bank guarantees are particularly crucial for developments under construction, as they ensure that any funds you pay in advance are fully safeguarded. This provides a safety net for your capital during the most critical phases of a project.

 

2. Guaranteed contractual compliance

This mechanism provides an additional layer of legal security by ensuring that all contractual commitments are strictly respected. It acts as a formal assurance that the developer will fulfill their obligations as agreed.

 

3. Increased developer credibility

For developers, providing a bank guarantee is a mark of professional excellence that significantly enhances market credibility. It demonstrates financial health and a commitment to transparency that builds lasting trust with investors.

 

4. Streamlined project financing

Beyond security, bank guarantees play a functional role in the growth of a project by helping developers facilitate and secure necessary financing. This ensures the development has the financial backing required to move toward a successful delivery.

 

Common types of bank guarantees in Portugal

Several types of bank guarantees are used in Portugal, depending on the nature of the transaction.

 

Performance guarantees

Used to ensure that contractual obligations, such as construction works or service delivery, are properly fulfilled.

 

Advance payment guarantees

Common in construction and development projects, these guarantees protect advance payments made before the work is completed.

 

Payment guarantees

Designed to secure payment obligations in commercial contracts or leasing agreements.

 

Real estate-related guarantees

Frequently required in off-plan property purchases or development projects to protect buyers against non-completion or breach of contract.

 

When do you need a bank guarantee?

For most people, bank guarantees are not part of everyday life — until they suddenly are. They usually come into play when you’re making a significant financial commitment and need protection against risk, delays, or non-performance.

Here are the most common situations where individuals and families may need — or be asked for — a bank guarantee.

 

Buying a house under construction (off-plan)

If you’re buying a home that is still being built, Portuguese law often requires the developer to provide a bank guarantee covering the amounts you pay in advance. This guarantee protects you if the project is delayed, suspended, or not completed, ensuring that your advance payments can be recovered.

In practice, you should always ask whether a bank guarantee exists for your payments, what amounts it covers and under what conditions it can be called.

 

Working with a contractor to build or renovate a house

When you hire a contractor for construction or major renovation works, a bank guarantee may be required on either side, depending on the contract. For instance, you may ask for a performance guarantee to ensure the works are completed as agreed. A payment guarantee can be requested by the contractor, especially for large projects, to secure future payments.

 

Renting property or commercial space

In some leasing agreements — particularly for commercial properties — landlords may request a bank guarantee instead of (or in addition to) a cash deposit. For tenants, this avoids tying up large sums of money upfront, while still giving the landlord financial security.

 

Participating in property or investment transactions

Bank guarantees are also common in property reservation agréments, investment or partnership arrangements and situations where funds are committed before all conditions are fulfilled.

 

Bank guarantees: costs and requirements

The cost of a bank guarantee varies depending on several factors, including:

• The guaranteed amount;
• The duration of the guarantee;
• The applicant’s financial profile and creditworthiness;
• The type of guarantee required.

 

Banks typically charge an annual commission, expressed as a percentage of the guaranteed amount. In many cases, the bank may also require collateral or additional security from the applicant.

 

What to consider before requesting or accepting a bank guarantee

Before moving forward with a bank guarantee, it is important to assess several practical and legal aspects that can significantly impact the effectiveness of this instrument.

 

1. Check if the terms are clear

The wording of a bank guarantee should be precise and unambiguous. The conditions under which the guarantee can be executed must be clearly defined, leaving no room for conflicting interpretations between the applicant, the beneficiary and the issuing bank.

 

2. Clarify the validity period

It is essential to ensure that the guarantee remains valid for the entire duration of the underlying contract. A guarantee that expires too early may leave the beneficiary unprotected, while an unnecessarily long validity period can increase costs for the applicant.

 

3. Enlist a reputable bank

The strength and credibility of the issuing bank are key elements of a reliable guarantee. Guarantees issued by well-established and regulated financial institutions provide greater security and are more readily accepted in complex or high-value transactions.

 

4. Align the bank guarantee with the underlying contract

The bank guarantee should accurately reflect the obligations set out in the main contract. Any mismatch between the guarantee terms and the contractual provisions may limit enforceability or delay execution in case of default.

 

5. Get legal and financial advice

Given the technical nature of bank guarantees, professional legal and financial advice is strongly recommended. Expert guidance helps ensure that the guarantee structure, wording and scope are appropriate for the transaction and aligned with Portuguese law.
