What is a Letter of Guarantee? How is it Obtained and Where is it Used?
A letter of guarantee is a strong financial assurance tool used in many business relationships, from public tenders to high-value commercial agreements. This article provides general information about the definition, application process, types, and cost structure of letters of guarantee.
In many transactions, from public procurement to large-scale private sector contracts, parties require additional assurance that obligations will be fulfilled. One of the most common tools providing this assurance is a letter of guarantee. As of 2026, stricter risk assessment criteria in banking and finance have made letters of guarantee even more critical in demonstrating a company’s financial reliability.
What Does a Letter of Guarantee Mean?
A letter of guarantee is an official document in which a bank undertakes to pay a specified amount if its customer fails to fulfill obligations toward a third party.
This structure consists of three main parties:
- Bank: The institution providing the guarantee
- Beneficiary: The party on whose behalf the guarantee is issued
- Applicant (or Obligee): The party requesting the guarantee
This mechanism reduces risks and strengthens trust, especially in high-value transactions.
How to Obtain a Letter of Guarantee?
Although the process may vary slightly between banks, it generally includes the following steps:
- The company submits a formal request to the bank
- The bank evaluates the financial status and credit history
- Appropriate collateral is determined (cash deposit, mortgage, guarantee, etc.)
- Commission rates and conditions are agreed upon
- The letter is issued and delivered to the relevant party
Up-to-date financial statements help speed up the process.
Who Can Obtain a Letter of Guarantee?
The following entities can apply:
- Sole proprietorships
- Limited companies
- Joint-stock companies
- Contractors
- Subcontractors
- Businesses participating in public or private tenders
Banks evaluate financial strength, creditworthiness, and collateral capacity.
Required Documents
Banks usually request:
- Tax certificate
- Signature circular
- Trade registry gazette
- Financial statements (balance sheet & income statement)
- Activity certificate
- Contract or tender documents
Requirements may vary depending on the type of guarantee.
How is it Used?
The letter is submitted during contract signing or tender applications. The bank guarantees that obligations will be fulfilled.
If the company fails to meet its obligations, the beneficiary can directly claim the amount from the bank. Therefore, it is a key tool for building trust in large-scale projects.
