什么是IN BLANK ？

空白背书-IN BLANK
Endorsing a bill of lading in blank means that there is no specified recipient of the bill.

Banks usually require a bill of lading to be made out to the bank’s order (‘to order of [name of bank]’) or to the shipper’s order (‘to order’ or ‘to order of shipper’) and endorsed by the shipper to order of the bank or in blank. This enables the bank, the buyer or any other named entity to take possession of the goods.

For a bank involved in trade finance transactions, having control of the rights to the goods under a bill of lading can be of paramount importance because:
1. it can be the bank’s security in case the obligor defaults;
2. some bank regulators allow application of lower risk‑weighted assets when the bank has control over the flow of the goods.
