Back-to-Back Letters of Credit Structuring Services
Back-to-back Letters of Credit are used when an intermediary needs to buy goods from a supplier and sell them to an end buyer,
but cannot fund the supplier without a bank-grade payment undertaking. The structure uses an incoming LC (from the end buyer)
as the foundation to issue a second LC (to the supplier), with controlled terms that protect the intermediary’s margin and execution timeline.
This structure only works when the paperwork is clean. The two credits must be engineered so the supplier can present compliant documents
while the intermediary can still present to the buyer without creating mismatches, timing gaps, or document traps.
Financely structures back-to-back LC transactions under UCP 600 and coordinates execution through regulated banks.
We are an advisory firm and do not issue LCs. All outcomes are subject to underwriting, KYC and AML, sanctions screening, issuer policy, and definitive documentation.
Where Back-to-Back LCs Are Used
Intermediated Commodity Trades
- Intermediary sells to an end buyer on LC terms
- Intermediary must issue LC to supplier to secure supply
- Margin is captured through invoice differential and controlled costs
When Transferable LC Is Not Available
- Buyer refuses a transferable credit
- Supplier requires direct undertaking in their favor
- Transaction requires separate documentary terms per leg
Core Risk Themes
Document Mismatch Risk
The most common failure point is drafting two credits that look similar on paper but do not reconcile in practice.
Even small discrepancies in document wording, dates, or presentation windows can kill the transaction.
- Inconsistent document descriptions and data fields
- Misaligned Incoterms and shipment date logic
- Inspection language that cannot be satisfied on schedule
Timing and Presentation Windows
The supplier must present under the second LC early enough for the intermediary to re-present under the first LC without expiry pressure.
This requires disciplined buffers, not aggressive timelines.
- Expiry and shipment windows engineered with buffers
- Presentation periods harmonized across both legs
- Clear amendment authority and escalation pathways
How the Structure Works
| Step |
What Happens |
| 1) Buyer issues incoming LC
|
End buyer issues a documentary LC in favor of the intermediary (or a nominated entity) under UCP 600, subject to bank policy. |
| 2) Bank underwrites back-to-back issuance
|
The intermediary’s bank evaluates the incoming LC, the intermediary’s profile, margin/collateral, and risk controls before issuing the outgoing LC. |
| 3) Outgoing LC issued to supplier
|
The intermediary’s bank issues a second LC in favor of the supplier, engineered to produce documents that can be re-presented upstream. |
| 4) Supplier ships and presents
|
Supplier presents documents under the outgoing LC. If compliant, payment is made under that LC according to its terms. |
| 5) Intermediary re-presents upstream
|
Intermediary presents under the incoming LC to collect from the buyer, capturing the margin after costs and fees. |

FAQ
Is a back-to-back LC the same as a transferable LC?
No. A transferable LC allows the beneficiary to transfer certain rights to a second beneficiary under the same credit, subject to the issuing bank’s terms.
Back-to-back involves two separate credits. It is often used when transferability is not permitted or not commercially workable.
What usually breaks a back-to-back LC transaction?
Document mismatch, unrealistic timelines, inspection language that cannot be satisfied, and lack of margin or collateral support required by the issuing bank.
Most failures are drafting and control failures rather than market failures.
Do banks require cash margin for the outgoing LC?
Often, yes. The issuing bank will evaluate the incoming LC and may still require margin, collateral, or credit support depending on risk appetite and policy.
This is confirmed during underwriting.
Can you guarantee issuance?
No. Financely is an advisory firm. Issuance is subject to bank policy, underwriting, KYC and AML, sanctions screening, and executed documentation.
