If you need a letter of credit for a business transaction, your current bank may be the best place to begin your search. However, you may need to expand the net to include larger banks if you maintain accounts at a smaller financial institution.
Example: An Indian exporter receives an export LC from his overseas client in the Netherlands. The Indian exporter approaches his banker with a request to issue an LC in favour of his local supplier of raw materials. The bank issues an LC backed by the export LC.
