1, it's easy to cancel the warehouse receipt. You put things in someone else's warehouse, and there will be a certificate of deposit, called a warehouse receipt. Later, the warehouse receipt will be cancelled because of the shipment or the expiration of the warehouse receipt (so that the warehouse receipt in your hand will be recovered). The sharp increase in warehouse receipts may be due to the fact that the trading of this variety in the market is not optimistic now. Traders think that arbitrage is profitable now and pull the goods to the warehouse for delivery.

2. The cancellation of warehouse receipts is also one of the important tools for the makers (or the main holders of warehouse receipts) involved in futures trading to manipulate the futures price trend. They mainly change the inventory quantity announced by the exchange by registering and canceling warehouse receipts.

Standard warehouse receipt refers to the physical delivery certificate issued by the delivery warehouse designated by the exchange to the shipper after being uniformly formulated by the exchange and confirmed to be qualified by the warehousing acceptance.

Making warehouse receipt is the process of converting the goods that meet the standard contract into standard warehouse receipt, which generally needs to go through delivery forecast, goods warehousing, acceptance, designated delivery warehouse issuance, exchange registration and other links.

For futures varieties, cancel the warehouse receipt. The warehouse receipt has not been closed on the last day of the trading day (that is, there is still a contract in hand). Customers who want to trade the spot with the contract will trade with the warehouse receipt on the delivery day, and the warehouse receipt can pick up the goods from the warehouse. The type of cancellation of warehouse receipts generally refers to the automatic cancellation of warehouse receipts by customers without corresponding goods after the transaction is completed. Another is that the exchange thinks that there are not so many spot transactions, and in order to prevent the goods from deteriorating, it takes back the warehouse receipt and cancels it.

The legal holder of the registered warehouse receipt shall go through the delisting procedures at the exchange. The spot dealer delivers the goods that meet the delivery standard to the delivery warehouse of the exchange. After the delivery warehouse is qualified, it will issue a standard warehouse receipt to the holder, who will go through the registration formalities with the delivery department of the exchange. Only registered warehouse receipts can be delivered, and the total quantity is the inventory quantity announced by the exchange.
