After OKX launched in Hong Kong, it launched a 24/7 USDT margin Shein perpetual contract

Summary of Points

SHEIN/USDT starts trading at 07:00 UTC.

Contracts remain open on weekends.

Non-trading session prices use protected reference prices.

Perpetual contracts are not stocks.

Funding costs and price gaps may amplify losses.

OKX opened the SHEIN/USDT perpetual contract trading at 07:00 UTC on September 2. The product uses USDT as a margin and runs 24 hours a day, with capital rates usually settled every eight hours. OKX indicates that the upper limit of the funding rate is ±1%, but if this upper or lower limit is touched, it may be adjusted to be settled every hour.

Shein's Hong Kong shares were listed only the day before. The contract now allows eligible OKX users to go long or short after the spot market closes, while actual stock holders must wait for the next HKEx trading session.

Xiyin shares were still trading when the perpetual contract opened. Timing is important. Hong Kong time is eight hours ahead of UTC, which means that the contract comes online at 15:00 local time. The regular afternoon trading session of the Hong Kong Stock Exchange lasts until 16:00, followed by the closing auction, which may end between 16:08 and 16:10. Therefore, perpetual contracts are not a completely independent overnight market. Contracts have about an hour of real-time spot market pricing before the close of Xiyin shares. The real test comes after that, when the underlying stock stops being renewed and the contract continues to trade.

This also continues the direction OKX started earlier this year, when it launched equity perpetual contracts linked mainly to large U.S. companies. As our team has previously reported, these products allow cryptocurrency account holders to gain stock price exposure without the need for traditional brokerage accounts. Xiyin added a newly listed Hong Kong stock to this model.

Buying SHEIN/USDT is not buying Siyin shares

This difference is not just a disclaimer . Perpetual contract traders hold leveraged derivative positions, and their profits and losses are settled in USDT. They do not own Xiyin shares, cannot vote on shareholder matters, and do not receive dividends.

traditional stock purchase. The buyer holds shares in the company.

Trading Window: Hong Kong Market Trading Hours

Carrying Interest: Shareholders 'Rights and declared dividends

Main risks: Changes in underlying stock price

SHEIN/USDT on OKX

USDT as margin derivatives. Traders take positions on stock price movements.

Trading window: 24 hours a day, seven days a week

Carrying interest: no ownership, voting rights or dividends

Main risks: funding rates, leverage and clearing

This is why the contract should not be described as tokenized stock or partial stock ownership. It is a price exposure market, not a way to own a company.

How Hong Kong's post-close prices work

OKX's stock perpetual contracts use a separate order book, so their final transaction price can change when the Hong Kong market closes. However, the exchange does not allow the reference index to drift indefinitely. Its stock perpetual contract rules stipulate that index prices are limited to ±10% of the most recently available stock price during non-trading hours, weekends and holidays. OKX pointed out that the range may be adjusted based on market conditions.

In fact, this produces two prices worth noting. The last transaction price shows the price of the trader's most recent transaction. The markup price (used for clearing) combines the index price with the average basis of the OKX order book. Therefore, even if the spot share price cannot change before the Hong Kong Stock Exchange reopens, sharp fluctuations in perpetual contracts may affect leveraged positions.

Can perpetual contracts lead Xiyin's next opening of the Hong Kong Stock Exchange

It can provide clues, but it's too early to call it market-leading. The increase in overnight perpetual contract prices may reflect new information or bullish demand, or it may be a temporary premium due to order books, aggressive long positions, or traders paying funding rates to maintain positions. The next time the spot market opens, the difference will become apparent. If Hong Kong investors agree with the overnight trend, stock prices may open in the same direction. If you disagree, perpetual contracts may quickly narrow the spread or reverse.

No proof: the selling will continue after the market opens.

A strong positive funding rate

A negative funding rate

Why the reopening of the spot market brings the greatest risk?

Perpetual contract positions can be held overnight or weekend, but the underlying stock cannot react until trading on the Hong Kong Stock Exchange resumes. News about tariffs, consumer demand, regulations or the broader market could change market sentiment during this gap. When the spot market opens, its price may verify the trend of the perpetual contract, ignore it, or fluctuate violently in the opposite direction. This makes leverage a core risk. Traders may be right about the long-term direction, but they may still be forced to close their positions before the spot market reopens. Funding fees add additional costs to anyone holding positions that span multiple settlement windows.

What to pay attention to before the next HKEx opens

Percentage change since the last HKEx close: Compare directions, not just two displayed prices.

Last traded price and marked price: Large spreads are more important than superficial transactions.

Funding rate direction: Shows which party is paying fees to maintain exposure.

Order book depth: Large fluctuations that occur in the face of insufficient liquidity are less credible.

The first batch of transactions on the Hong Kong Stock Exchange: This is the only direct test to test whether the overnight trend holds true.

SHEIN/USDT provides a way for cryptocurrency traders to continue to bet on a company whose shares still follow Hong Kong trading hours. Whether this new market will be a useful preview of the next spot opening or just a more volatile place to open positions between trading hours will take several trading days to answer.
