How Cross-Exchange Funding Rates Shape Crypto Perpetuals
Positive or negative funding can reveal positioning pressure, but it is not a simple buy-or-sell signal.
Perpetual futures seek to keep contract prices aligned with the underlying asset through periodic funding transfers between long and short positions. The exact method and payment schedule vary by venue. A positive funding rate generally means one side pays the other under that venue's rules; it does not necessarily reflect net purchases of the spot asset.
Funding costs become meaningful when leverage is high or a trade stays open over many intervals. Differences in index calculation, risk controls and trader composition can create divergent rates across exchanges. Traders may also hedge spot inventory with derivatives, producing funding that appears crowded even without a straightforward directional view.
Check the reference index, payment frequency, current basis, open interest and liquidation mechanics together. A historical rate is not a promise about the next settlement. Margin products can lose money rapidly; the CFTC's customer guidance highlights those risks.
