External pledge should be your warehouse receipt pledge business at the clearing bank of the exchange or the designated bank, that is, the warehouse receipt you hold is mortgaged to the relevant bank for loan, and the loan amount does not exceed 70% of the warehouse receipt value.
Few people ask such a professional thing.
Supplement: The warehouse receipt must belong to the customer, and the released deposit must also be released to the customer's deposit account, not just to your seat account. In addition, when the standard warehouse receipt is used to offset the deposit, the settlement price of the futures contract in the latest delivery month corresponding to the standard warehouse receipt on the trading day before the processing day shall be used as the benchmark price to calculate its value. The offset limit is less than 80% of the value, which is four times that of the seat fund.
In addition, I emphasize once again that the discount is only the release of the deposit, and the released deposit cannot be opened! Offset is possible. Offset and offset are both called pledge.
The bank's warehouse receipt pledge cannot exceed 70%, unless you have an acquaintance.
The above is the answer to the difference between warehouse receipt pledge and warehouse receipt mortgage. Please check!
