Although real guarantees are of primary interest in banking operations, personal guarantees—particularly those of the client—constitute the initial basis of any credit transaction. These are grounded in attributes such as reliability, background, responsibility, integrity, and reputation for fulfilling obligations. The debtor demonstrates both moral and material solvency, yet banks may require additional guarantors, either due to specific circumstances or as part of general policy, as in certain personal loans where third-party guarantees are mandatory regardless of the debtor’s position.
This extension of responsibility ensures that the creditor faces insolvency risk only if both the principal debtor and the guarantor fail. When only the debtor’s personal guarantee is involved, operations are known as “signature-only,” although this modality is uncommon in medium- and long-term loans. While personal guarantees involve the entirety of a debtor’s assets and may appear broader in coverage, in financial terms their effectiveness depends on the actual economic capacity of the guarantor. Unlimited liability is therefore constrained in practice by the real value of available assets. For example, a corporation with limited liability but substantial capital may offer stronger financial security than an individual with unlimited liability but no assets. Consequently, personal guarantees are evaluated not only in economic terms but also in relation to the guarantor’s social, professional, and commercial standing.
Guarantees
When formalizing a loan, the bank assumes the risk of non-compliance by the borrower. Even when such risk has been assessed, additional safeguards are typically incorporated, especially in medium- and long-term financing. These guarantees aim to partially or fully cover potential losses if the borrower fails to meet obligations. They may also be required when dealing with new or unknown clients.
Most financing obtained through negotiated sources involves guarantees, as do the majority of banking operations over extended terms. Clients generally accept these requirements to increase their access to credit. Traditionally, the need for guarantees is inversely related to the borrower’s financial strength: entities with limited assets face stricter requirements, while stronger financial backing reduces the need for additional guarantees.
Real estate guarantees have historically been the most valued, although today various types of commercial assets can serve as collateral. However, legal frameworks in many jurisdictions have not fully adapted to this broader approach, limiting their practical application. In some cases, insufficient legal clarity weakens enforcement, delays creditor actions, or allows the underlying asset to lose value over time. For this reason, less common forms of guarantees require careful legal analysis, though they should not be dismissed without financial evaluation, as they may offer viable solutions in complex operations.
In summary, to mitigate the risk of non-recovery at maturity, creditors impose additional obligations that strengthen the original commitment. These guarantees may involve the debtor or a third party. Two main categories exist: personal and real guarantees. Short-term credit generally relies on personal guarantees, while long-term financing tends to require real guarantees, although both may be combined depending on the case.
In real guarantees, a specific asset is pledged by the debtor or a third party, creating a direct right over that asset. In personal guarantees, a third party assumes responsibility—either subsidiarily or jointly—for the debtor’s obligation, allowing the creditor to claim against the guarantor’s entire estate in case of default.
