AI Trade Finance Document Checking

A documentary letter of credit is a bank's promise to pay a seller if the seller presents documents that comply with the credit's terms. Under the ICC's Uniform Customs and Practice for Documentary Credits (UCP 600), banks deal with documents, not goods, and examine documents on their face. UCP 600 gives a bank a maximum of five banking days after the day of presentation to decide whether a presentation complies. Detailed examination practice is set out in the ICC's International Standard Banking Practice guidance. Examination is painstaking. An examiner checks that each required document is present, that data is consistent across documents without needing to be identical, that dates fall within the permitted windows, that amounts do not exceed the credit, and that the goods description on the invoice corresponds with the credit. Discrepancies are common, and each one can lead to refusal or a request for the applicant to waive it. AI helps in layers. Optical character recognition and document-understanding models turn scans into structured fields. Classification identifies which document is which. A rules layer, often encoding banking practice as explicit checks, compares extracted fields with the credit terms and with each other. Language models can help interpret free-text clauses and compare goods descriptions. Specialist vendors such as Traydstream and the trade platforms of large banks offer this kind of automated checking. The same pipeline supports financial-crime controls. The FATF and the Egmont Group have described trade-based money laundering typologies such as over- and under-invoicing, multiple invoicing for one shipment, phantom shipments and misdescribed goods. AI can compare prices with benchmarks, screen parties, ports and vessels, and detect unusual routes. A frequent misconception is that AI can make the final compliance decision alone. In practice the examiner remains responsible, and the system's value is extracting data, prioritizing risk and documenting why each discrepancy was raised.
