A standby letter of credit (SBLC) is a bank guarantee that pays the beneficiary if the applicant (borrower/contractor) fails to perform a specified obligation. Used in trade, construction performance, and lease security. Borrowers typically pay 1–3% per year in fees for SBLC issuance.
An SBLC is a secondary payment guarantee — it only pays if the primary obligor (the applicant) fails to perform. This distinguishes it from a commercial letter of credit (used for primary payment in trade transactions). The SBLC says: 'If my client doesn't pay/perform, the bank will.' The beneficiary presents documentation of non-performance to trigger the bank's payment obligation. SBLCs are issued by banks and secured similarly to a loan — the applicant typically provides cash collateral, a pledge of other assets, or an unsecured credit facility backing the SBLC. The bank charges an annual fee (typically 1–3% of the face amount, sometimes lower for well-secured or investment-grade applicants). The SBLC itself does not represent drawn cash — it is contingent liability that becomes actual liability only upon a draw. Common SBLC uses: (1) International trade — seller in one country requires payment assurance from foreign buyer's bank. (2) Construction performance — owner requires SBLC from contractor guaranteeing project completion (alternatively, a performance bond from a surety). (3) Lease security — landlord requires SBLC instead of cash security deposit, allowing tenant to keep cash deployed in operations. (4) Government contract performance. (5) Credit enhancement — borrower provides SBLC to a lender as additional credit support. For SMBs, obtaining an SBLC requires sufficient bank credit availability. Banks typically count SBLCs against the borrower's credit facility (a $1M SBLC reduces available revolving credit by $1M). The annual fee is a real cash cost — model it as a financing cost when evaluating whether SBLC-based credit enhancement is cost-effective.
Both guarantee performance, but they use different mechanisms. An SBLC is a bank instrument — the bank pays the beneficiary upon presentation of specified documents. A performance bond is a surety instrument — the surety company either pays the beneficiary or completes the project itself. SBLCs are more common in financial transactions; performance bonds are more common in construction. Surety bonds typically involve a three-party claims adjustment process; SBLCs are payable on document presentation.
An SBLC is a contingent liability — it only becomes actual debt if drawn. On a GAAP balance sheet, issued SBLCs are disclosed as off-balance-sheet contingent obligations. However, lenders and rating agencies typically include committed SBLCs in leverage analysis as if they were drawn. From a practical credit perspective: the bank issuing the SBLC treats it like a loan commitment and charges it against your credit availability.
For businesses with existing bank credit facilities: 1–5 business days for issuance (credit approval already in place, standard SBLC documentation). For new applicants without existing credit: 2–4 weeks for full credit underwriting plus SBLC issuance. SBLCs require the same credit review as loans of equivalent amount.
