【答案解析】[解析] 25-27
Back-to-Back credits consist of two entirely separate documentary credits, but one credit may act as security for the other. They apply in transactions when actual suppliers and ultimate buyers deal through a middleman. If the supplier insists on a documentary credit, the middleman may apply to his bank for a credit on his behalf. If the middleman's bank is satisfied with his creditworthiness, the bank will issue the credit in the normal way and no other formalities will apply. However, the "back-to-back" credit comes into use if the bank insists that the middleman obtain a documentary credit in his favor from the ultimate buyer as security for the "back-to-back" credit in favor of the actual supplier. Only the middleman and his banker know the "back-to-back" credit, and only they are concerned with credit.

In whose favor is the back-to-back credit issued.?

录音原文提到However, the "back-to-back" credit comes into use if... "back-to-back." credit in favor of the actual supplier. 背对背信用证的产生是由于中间商银行坚持中间商持有一个来自最终买方的以银行自己为收款人的跟单信用证,作为其开立以供货方为收款人的信用证的担保。由此看出背对背信用证对中间商银行有利。
