Introduction to Funding Rates in Perpetual Contracts
Funding rates act as the "leash" that keeps perpetual contracts aligned with their underlying spot indices. Think of perpetual contracts as a wandering bull—the spot index is the path, positive premium is above the path, and negative premium lies below. The funding rate mechanism ensures the bull stays on track by pulling it back when it strays too far from the fair value.
