Risk management measures
The risk management of the Exchange adopts the margin system, the price limit system, the speculative position limit system, the large account reporting system, the compulsory position closing system and the risk warning system.
1. Margin system
Trading margin refers to the funds that a member guarantees the performance of the contract in the exchange account, which is the occupied margin. natural rubber The minimum trading margin for standard contracts is 5% of the contract value.
The Exchange formulates different standards for the collection of trading margins according to the different number of positions of a standard contract and the different stages of the listing operation (that is, from the date of the new listing of the contract to the last trading day). The specific provisions are as follows:
During the trading process, when the position of a standard contract reaches the total position of a certain level, the collection standard of trading margin will not be adjusted temporarily. At the settlement of the day, if the position amount of a standard contract reaches the total position amount of a certain level, the Exchange will charge the trading margin corresponding to the total position amount for all positions of the contract. If the margin is insufficient, it shall be added in place before the opening of the next trading day.
When a certain standard contract reaches the standard that the trading margin should be adjusted, the Exchange shall settle all historical positions of the contract according to the new trading margin standard at the time of settlement on the trading day before the implementation of the new standard. If the margin is insufficient, it shall be added in place before the opening of the next trading day.
After entering the delivery month, the seller can use the standard warehouse receipt as the performance guarantee of the standard contract position in the delivery month with the same quantity as that shown, and the trading margin corresponding to its position will not be collected.
2. Price limit system
The price limit refers to the maximum range of intraday price fluctuation allowed by the standard contract. The quotation exceeding this range is deemed invalid and cannot be concluded.
In the trading process of a standard contract, the Exchange may adjust the limit range of its rise and fall according to the market risk when the following situations occur:
（1） When the standard contract price rises or falls continuously in the same direction; （2） In case of national statutory long holidays; （3） When the Exchange considers that the market risk changes significantly; （4） Other circumstances deemed necessary by the Exchange.
If the exchange decides to adjust the range of the limit according to the market conditions, it shall make an announcement and report to the CSRC.
Where two or more of the price limits prescribed in these Measures are applied at the same time, the price limit shall be determined according to the highest value of the prescribed price limit.
The price limit of natural rubber standard contract shall not exceed ± 3% of the settlement price of the previous trading day. When a natural rubber standard contract has a unilateral market on a certain trading day (the trading day is called D1 trading day, and the following trading days are called D2, D3, D4, D5, and D6 trading days respectively), the adjustment of the price limit of the standard contract and the collection of trading margin are as follows:

Measure 1: On the D4 trading day, the Exchange decided and announced that on the D5 trading day, it would take one or more of the unilateral or bilateral, the same or different proportion, some members or all members to increase the trading margin, suspend some members or all members to open new positions, adjust the range of up and down limit, limit cash, close positions within a time limit, and forcibly close positions to mitigate market risks, However, the adjusted range of price limit shall not exceed 20%. After the Exchange announces the adjustment of the margin level, those with insufficient margin shall be added in place before the opening of the D5 trading day. If the rise and fall of the standard contract does not reach the daily limit on D5 trading day, the rise and fall limit and the trading margin ratio of the standard contract on D6 trading day will return to the normal level; If the rise and fall of the standard contract on the D5 trading day and the D3 trading day reach the daily limit again in the same direction, the Exchange will declare it an abnormal situation and take risk control measures according to relevant regulations; If the rise and fall of the standard contract on the D5 trading day and the D3 trading day reach the daily rise and fall limit in the opposite direction, it will be deemed as the beginning of a new round of unilateral market, and that day will be deemed as the D1 trading day. The trading margin and rise and fall limit on the next day shall be subject to Article 12 of the Shanghai Futures Exchange Risk Control Management Measures.
Measure 2: At the time of settlement on the D4 trading day, the Exchange will automatically match the unsettled closing positions declared at the up and down limit prices on the D3 trading day with the profitable customers (or non members of futures companies, the same below) of the net positions of the contract at the up and down limit prices on the D3 trading day according to their positions. If the same customer holds a two-way position, he/she should first liquidate his/her own position, and then liquidate the position according to the above method.
3. Risk management when prices fluctuate significantly
When the cumulative increase and decrease (N) of a natural rubber standard contract for three consecutive trading days (i.e. D1, D2, D3 trading days) reaches 9%; Or the cumulative increase or decrease (N) of four consecutive trading days (i.e. D1, D2, D3, D4 trading days) reaches 12%; Or five consecutive trading days (i.e. D1 D2, D3, D4, D5 trading days), when the cumulative increase or decrease (N) reaches 13.5%, the Exchange may, according to the market situation, unilaterally or bilaterally, with the same or different proportion, increase the trading margin of some members or all members, restrict some members or all members to contribute money, temporarily suspend some members or all members to open new positions, adjust the limit of increase or decrease, and close positions within a time limit, One or more of the measures such as compulsory position closing, but the adjusted range of the limit of rise and fall shall not exceed 20%.

The Exchange shall issue special VAT invoices to the buyer members and collect special VAT invoices from the seller members.

If a member delays in submitting the special VAT invoice for 3 to 10 days, a late fee of 0.5 ‰ of the amount of the payment for goods will be imposed every day; If the payment is delayed for 11 to 30 days, a late fee of 1 ‰ of the amount of the payment will be charged every day; If the special VAT invoice has not been paid for more than 30 days, it shall be deemed that the special VAT invoice has not been paid, and a fine of 20% of the amount of goods payment shall be imposed.
