China to Ban Derivatives Funding for Stock Trades, CSRC Says

China has made a big change to its stock market rules. The Securities Association of China (SAC) will stop brokers from giving money to traders through derivatives. This decision was announced by Zhang Xiaojun, a spokesperson for the China Securities Regulatory Commission (CSRC), on a Friday meeting.

What is the new rule?

The new rule says that brokerages cannot offer financing for stock trades that uses derivatives. In simple words, a broker cannot lend you money to buy stocks if the loan is based on a swap or a similar contract.

Brokerages must only give financing that follows the official guidelines. The CSRC wants to make sure that any loan is safe and transparent.

Why did regulators make this rule?

Regulators say that some swaps have become a way to give risky loans to speculators. Swaps should be a risk‑management tool, not a shortcut to cheap money.

China has seen a big market crash in the past. That crash was helped by too much borrowing in the money market. The regulators do not want a repeat of that event.

Earlier this month, the two main stock exchanges in China raised margin requirements to 100 percent. That means traders must put up the full amount of money to buy stocks, instead of borrowing half the cost.

Chen Xingyu, an analyst at Phillip Securities Research in Shanghai, said the regulators now understand the danger of too much leverage. He added that the focus will stay on lowering risk and keeping the market safe.

How does the rule affect brokers and investors?

Brokerages will have to stop offering loans that are based on swaps or other derivative contracts. They can still give normal margin loans, but those must follow the 100 % margin rule.

Investors who used total‑return swaps to trade stocks will need to find other ways to fund their trades. Some may have to use their own cash, or look for approved loan products.

The rule also sends a clear message to banks and other financial firms. They must treat swaps as risk‑management tools, not as a source of cheap credit.

What are swaps and how do they work?

A total‑return swap is a contract between a bank and an investor. The investor pays a small fee to the bank. At the end of the contract, the investor receives the profit (or loss) from a stock or a basket of stocks.

Because the investor only pays a fee, the swap can give a leverage of three to five times. This means a small amount of cash can control a much larger amount of stock value.

According to data from the SAC, 39 banks held swaps worth 279 billion yuan (about $43.7 billion) at the end of October. Swaps made up 44 % of that amount, while options made up the rest.

The official interest‑rate market in China is over 1.2 trillion yuan. That means swaps are a small but still important part of the whole market.

Recent related actions

China has been tightening rules on swaps in other areas too. On 26 June 2026, Reuters reported that the CSRC ordered curbs on cross‑border swaps. The move was meant to stop risky overseas exposure.

At the same time, investors are looking at Chinese stocks as an alternative to crowded AI trades. Yahoo Finance noted on 5 September 2026 that many traders see Chinese equities as a fresh opportunity.

These recent stories show that China is trying to keep its markets stable while still attracting new money.

FAQ

What is a derivative?

A derivative is a contract whose value comes from something else, like a stock price or an interest rate. Common derivatives are swaps, futures, and options.

What does “leverage” mean?

Leverage means using a small amount of money to control a larger amount of investment. It can increase profit, but it also raises risk.

Can I still trade stocks after the ban?

Yes. You can still buy and sell stocks. You just cannot use a broker‑offered loan that is based on a swap or similar derivative.

What happens if I already have a swap contract?

Existing contracts are likely to be allowed to finish their term, but no new swap‑based financing will be offered. You should check with your broker for specific details.

Conclusion

The China derivatives funding ban is a clear step by the CSRC to lower risky borrowing in the stock market. By stopping brokers from using swaps for loans, regulators hope to avoid another market crash. Investors will need to rely on cash or approved margin loans for stock trades. The rule fits into a wider push to tighten swap rules, both domestically and across borders. For anyone trading Chinese stocks, understanding these changes is key to staying safe and compliant.
