Why Funding Rates Turn Positive or Negative on Hyperliquid
Funding becomes positive when perp demand pushes the market rich relative to its reference and negative when it trades cheap, transferring value between longs and shorts to encourage convergence.
Funding is a balancing payment between perpetual longs and shorts. On Hyperliquid, the rate reflects a fixed interest component plus a premium component derived from the relationship between the perp market and reference pricing. Positive funding generally means longs pay shorts; negative funding means shorts pay longs. The rate is an incentive, not a prediction of where price must move next.
Premium drives most regime changes
When aggressive long demand keeps the perp above its reference, the premium component rises and funding tends to become more positive. Short demand can push the relationship the other way.
A high positive rate tells you positioning is expensive for longs. It does not prove the asset is about to fall.
Sampling and payment
Hyperliquid samples premium information repeatedly and makes funding payments on its documented schedule. The rate displayed in an interface is therefore the result of a time process rather than one instantaneous spread observation.
For backtesting, use historical funding payments or reconstructed historical inputs rather than applying today's rate backward.
Caps matter in stress
Funding can be capped under protocol rules. In extreme markets, the economic pressure required to align perp and spot may exceed the permitted payment rate, so basis can remain wide.
This is another reason funding should not be treated as a guaranteed arbitrage yield.
Reading funding with open interest
Positive funding plus expanding open interest can indicate increasingly expensive long positioning. Positive funding with falling open interest can reflect positions being reduced. Negative funding can similarly occur under aggressive short demand.
Funding becomes much more informative when read with price, OI, volume, and liquidations.
Strategy implication
A carry trade should model funding as a stochastic cash flow that can change sign. Size based on a range of rates and include entry/exit basis and financing costs.
