If you miss the subscription cutoff for a tokenized fund, that day's yield will not be counted. What matters is not the time you submit the subscription, but the time your application is officially confirmed.
Core rule: Subscribe on T day, yield starts on T+1
Tokenized money market funds follow the same standard rule as traditional money market funds. OSL's Taikang Kaitai USD Money Market Fund clearly states: for T+0 subscriptions, yield accrues daily starting from T+1. BlackRock's BUIDL fund follows the same logic: after funds are confirmed, the fund begins to calculate the corresponding fund shares, and then Securitize issues digital shares on-chain.
The cutoff time is the dividing line. HashKey's GFUSD rule is: subscription requests submitted before 9:00 AM Hong Kong time on a trading day are processed on that day (T day); those submitted after 9:00 AM are carried over to the next trading day (T+1). If you submit after the cutoff, it is treated as if it was accepted on the next trading day, and the yield start date is also delayed by one day.
Why missing the cutoff means no yield for that day
A money market fund works like this: your money must first enter the fund account and be allocated before it can start earning yield. China Universal Fund's rules state this logic directly: fund shares subscribed before 3:00 PM on a trading day are entitled to distribution rights from the next trading day.
Your on-chain transfer may be confirmed in minutes, but the fund administrator still needs to complete fund confirmation, calculate shares at that day's net value, and mint tokens on-chain. These back-office tasks are not completed automatically on-chain; they have clear working time windows. The cutoff is designed so that all back-office processing can be completed on the same day. Once that time passes, the whole process moves to the next working day.
Special cases: Some products may have slight differences
Most tokenized money market funds (such as OSL's Taikang Money Market Fund and HashKey's GFUSD) follow the general T+1 yield rule. Some traditional money market funds may pay interest at a demand deposit rate during the initial offering period rather than the normal subscription period, but that is a special stage before the product is officially launched, not an everyday subscription situation.
Next steps
Confirm your T+1 yield start date: If you submit before the cutoff (for example before 9:00 AM), that day is T day, and yield starts from the next working day (T+1). If you submit after the cutoff, the next working day becomes the new T day, and yield starts from the working day after that.
Check subscription status in the fund app: If the order status changes from "Submitted" to "Confirmed" or "Processing," it means shares have been created. Yield is calculated from the share confirmation date, not from the moment you submitted the subscription or completed the on-chain transfer.
