The Difference Between a Standby LC & a Bank Guarantee
The Difference Between a Standby LC & a Bank Guarantee
At first glance, a Standby Letter of Credit (SBLC) and a Bank Guarantee (BG) seem interchangeable. Both serve as a safety net when a buyer or contractor defaults. Both are issued by banks. And both can be called if the counterparty fails to perform. But legally and operationally, they’re governed by very different rule sets—each with its own impact on how claims are made, processed, and paid.

UCP 600 – Documentary Credits
UCP 600 is the rulebook used for commercial letters of credit and occasionally applied to SBLCs. It defines how documents are examined, what constitutes a valid presentation, and how banks handle discrepancies. SBLCs under UCP 600 follow strict documentation and timing rules, with a five-day examination window.
URDG 758 – Demand Guarantees
URDG 758 is the go-to rule set for Bank Guarantees. It allows automatic extension clauses, sets a 30-day presentation period if none is stated, and gives clearer guidance on when a demand can be rejected. It's widely adopted in Europe and Asia for structured performance guarantees, especially in construction and EPC contracts.
ISP 98 – Standby Letters of Credit
ISP 98 was designed specifically for SBLCs. It modernizes standby procedures, allows electronic presentation, and clarifies when a bank is obligated to pay. It also includes rules on partial drawings and variation clauses—something UCP 600 lacks. Most US-issued SBLCs today are governed by ISP 98.
Why It Matters
Using the wrong instrument can delay execution, block payment, or breach contract terms. A European EPC contractor asking for a BG under URDG 758 won’t accept an SBLC under ISP 98. A US beneficiary may insist on an SBLC because their compliance process doesn’t handle guarantees. The rule set shapes enforceability and comfort.
