KuCoin has activated a rule that automatically shifts USDT- and USDC-margined perpetual contracts to hourly funding settlement once a contract's funding rate hits its upper or lower limit. The change took effect after 08:00 UTC on Aug. 17 and applies at the next funding period without a separate announcement. For traders, it means funding events can arrive far more frequently when rates run hot — though the cumulative cost doesn't change.
How the trigger works
The mechanism is tied to each contract's funding cap and floor. At a scheduled settlement, if the funding rate is at or above the contract's upper limit, or at or below its lower limit, KuCoin switches that contract to a one-hour interval — unless it's already settling hourly. The exchange didn't apply a universal cap or starting interval. Its announcement uses a Bitcoin perpetual with upper and lower limits of plus and minus 0.3% as an example.
The 36-hour reset
Getting back to the standard four-hour schedule takes time. KuCoin requires 36 consecutive one-hour settlements with an absolute funding rate no greater than 0.002%. Any reading above that threshold resets the count. Once all 36 periods qualify, the contract moves to four-hour settlement starting with the 37th period — again, without a separate notice.
What traders actually pay
KuCoin says the interval adjustment changes only settlement frequency. Funding calculations, funding limits, and users' positions remain the same. Funding may be debited or credited more often, but cumulative cost still depends on the realized rates, the side and size of the position, and how long it remains open. So it's a timing shift, not a price change.
Where the rule stands now
At 20:15 UTC on Aug. 17, KuCoin's live XBT USDT M contract data showed a cap of 0.003, a floor of -0.003, and an eight-hour interval. The current funding rate fell within those limits, so that contract hadn't entered the hourly phase. The broader active-contract data showed only COTI USDTM on an hourly interval, but that cycle began July 28 under a separate notice — before the automatic rule took effect. So the first-day reading didn't identify any contract newly in automatic hourly mode.
The rule is live. The next time a contract's funding rate touches its cap or floor, the hourly clock starts automatically — and traders won't get a heads-up beyond the rate itself.
