Inventory (spot) pledge loan means that the borrower borrows money from the lender with inventory as pledge. In order to realize the transfer and possession of the pledge, the lender entrusts a logistics enterprise or an asset management company to become a third-party enterprise to supervise and keep the inventory as the pledge on its behalf. Characteristics of inventory (spot) pledge First of all, because financial institutions are not allowed to engage in business activities in other fields except financial services, to realize the possession of movable property, it is necessary to provide collateral storage services with the help of a third party (storage company) other than the borrower. The warehousing company takes the financial institution as the depositor to issue warehouse receipts and deliver them to the financial institution. At this time, financial institutions do not directly possess collateral, but indirectly manage and possess goods through warehousing companies. Secondly, financial institutions have neither the ability nor the possibility to actually supervise and control the collateral. Instead, the warehousing company provides warehousing supervision services for the collateral stored in the warehousing center according to the inventory (spot) pledge loan contract signed by the borrower and the financial institution and the inventory supervision contract signed by the three parties. Thirdly, the goods used by enterprises to guarantee have a great influence on the operation of their production and marketing supply chain. In order to ensure the smooth repayment of enterprises, financial institutions are required to minimize the impact on the normal production and business activities of borrowers while realizing the possession of collateral, and allow enterprises to pick up or replace goods during the supervision period. Storage companies must be able to coordinate the regulatory needs of financial institutions and the production and marketing activities of borrowers. Therefore, the collateral pledged by inventory (spot) is variable.
