Letters of Credit for Crude Oil: What a Buyer's Bank Will and Won't Issue

Payment security is where most crude oil deals are won or lost. Buyers want assurance the product will arrive. Sellers want assurance they will be paid. Letters of credit, standby letters of credit and escrow all claim to solve this, but they do different jobs, and scam offers routinely misuse all three.

Three Instruments, Three Different Jobs

Documentary letter of credit (LC). A bank undertakes to pay the seller once the seller presents documents that comply with the LC’s terms, such as the bill of lading, certificate of quality and quantity, and commercial invoice. It is the standard payment instrument for cargo-based crude trade. It is governed by the ICC’s UCP 600 rules.

Standby letter of credit (SBLC). A guarantee of last resort. The bank pays only if the applicant fails to pay under the contract. It is a backstop for credit risk, not a primary payment method, and is typically governed by ISP98 or UCP 600.

Escrow. A neutral third party holds funds and releases them when agreed conditions are met. It can work for smaller or unusual transactions, but it is only as trustworthy as the escrow agent.

What a Buyer’s Bank Will Typically Issue

A bank issues an LC or SBLC against the buyer’s credit relationship, a credit line, or cash collateral. Before issuing, it will ask for:

  • A signed sales and purchase agreement, or a draft the bank has reviewed.
  • Know-your-customer and sanctions screening on both buyer and seller, and often on the vessel and the cargo origin.
  • Credit approval or collateral covering the face value.
  • Fees, usually charged as a percentage of face value per quarter.

The key point: banks issue instruments for their own customers, on their own terms, through their own channels. A bank will not issue an instrument because a broker or seller asks it to, and the seller does not choose the buyer’s issuing bank.

How Scam Offers Misuse Each Instrument

These patterns appear repeatedly in fraudulent crude offers.

  • “Lease an SBLC” or “buy a BG/SBLC”. Genuine banks do not sell or lease instruments to third parties for resale. Offers of this kind, often with an upfront fee, are a classic advance-fee scheme.
  • Seller demands a “performance bond” or LC from the buyer before any documents are shown. Instruments should follow a verified, signed contract, not precede it.
  • SBLC offered as the primary payment on a spot cargo. An SBLC only pays on default, so it does not match a documented delivery.
  • Unverifiable issuing bank. The bank is obscure, unlicensed, or the SWIFT message arrives as a PDF rather than through the banking system.
  • Escrow agent chosen by the seller and unknown to the buyer, or an escrow “law firm” with a new domain and no verifiable registration.
  • Fees to “activate” or “validate” the instrument before any product is verified.

Verification Steps Before You Rely on Any Instrument

  1. Confirm authenticity bank to bank. A genuine LC is transmitted by SWIFT (for example, an MT700 message) between banks. Have your own bank authenticate any instrument you receive, using contact details you sourced independently.
  2. Check the issuing bank’s standing. Confirm it is a licensed bank with a correspondent network. Consider asking for a confirming bank if country or bank risk is a concern.
  3. Read the documentary conditions. Each required document is a condition for payment. Unachievable or ambiguous terms are a warning sign, and so are terms that let one party alter conditions unilaterally.
  4. Match the instrument to the deal stage. An LC follows a signed, verified contract. See our guides on reading a buyer’s LOI and proof of product.
  5. Never pay a fee to the counterparty for an instrument. Bank fees go to banks, through your own account.
  6. Pair payment with independent inspection and delivery terms, as covered in FOB vs CIF.

Which Instrument Fits Which Deal

  • Single cargo, new counterparties: a confirmed documentary LC, payable against compliant shipping documents.
  • Term contract with an established relationship: an LC for each cargo, plus an SBLC as a backstop for open credit.
  • Small or irregular transactions: escrow with a regulated, independently verified agent may be workable, though it is less common in large crude trade.

These are general principles, not legal or banking advice. Your bank and counsel should confirm what applies to your transaction.

Takeaway

An LC pays against documents, an SBLC pays on default, and escrow holds funds for a neutral release. Real instruments come from a real bank, through the banking system, against a verified contract. If someone is selling, leasing or “activating” an instrument, treat that as the warning. If you have received a payment instrument or proposed structure you are unsure about, BarrelBridge can review it with you before you commit. Schedule a consultation.
