Surety bonds for contractual obligations
A surety bond is a contractual arrangement involving the business required to perform an obligation, the beneficiary of that obligation and the surety provider.
Depending on the terms, the bond provides the beneficiary with financial protection if the specified contractual obligation is not met.
Surety facilities can be relevant to contractors and project-based businesses that regularly need bonding capacity while managing their broader bank facilities and working capital.

What Surety Providers Assess

Types of Surety Bonds
Potential bond types include:
- Tender bonds
- Performance bonds
- Advance payment bonds
- Retention bonds
- Other contract-specific bonds
Availability and wording depend on the contract and surety provider.
Who Uses Surety Bonds?
They are commonly relevant to sectors including construction, engineering, infrastructure, mining services and other project-based industries where principals require contractual security.

Bank guarantees for commercial obligations
A bank guarantee is an undertaking issued by a bank or other eligible provider in favour of a beneficiary.
Businesses may be asked to provide guarantees where a landlord, project principal, supplier or other counterparty requires financial assurance.
Common Uses
Bank guarantees may support:
- Commercial leases
- Tenders
- Contract performance
- Supplier arrangements
- Other agreed commercial obligations
How Bank Guarantees May Be Secured
The security required depends on lender policy and borrower circumstances. Structures may include cash backing, property-supported facilities or other approved security arrangements.
The amount of cash or security tied to a guarantee can affect the liquidity available elsewhere in the business.

Comparing surety bonds and bank guarantees
Both can support contractual obligations, but they are not interchangeable.
A bank guarantee generally sits within a banking or guarantee facility and may require cash or other security. A surety bond is issued through a surety arrangement and may provide an alternative source of bonding capacity for eligible businesses.
The appropriate option depends on the contract wording, beneficiary requirements, business strength, existing facilities and available security.
