Letters of Credit (L/C) Vulnerability stems directly from the legal “doctrine of corporate autonomy” (enshrined in Uniform Customs and Practice for Documentary Credits – UCP 600), which mandates that financial institutions deal exclusively in documentation and completely ignore the physical status, quality, or existence of the underlying goods. This structural blind spot makes L/Cs the premier vehicle for documentary trade fraud; collusive networks present flawless paperwork to clear automatic payments for phantom cargos, while banks are legally blocked from looking behind the text of the presented invoices during standard document examination phases.
