Perpetual futures are popular because they let traders hold directional exposure without an expiry date. Kraken’s explainer emphasizes that funding helps keep the contract price anchored to the underlying spot market, with payments moving between long and short traders depending on whether the perpetual trades above or below spot.
That makes funding rates more than a fee line. Positive funding often means longs are paying shorts and bullish leverage is crowded; negative funding often means shorts are paying longs and bearish leverage is crowded. Neither reading is automatically a trade signal, but both show where pain can build.
Binance’s futures documentation also shows why traders should not ignore mechanics. Funding is calculated from position notional and the funding rate, caps and floors can apply, and settlement frequency can be adjusted during extreme conditions. A position that looks cheap at entry can become expensive if funding spikes or settles more frequently.
The practical risk rule is to include funding in the trade plan before opening the position. Define how many funding cycles the trade can tolerate, compare perpetual price with spot price, and avoid assuming high funding must immediately reverse. Crowded trades can stay crowded until a liquidation cascade forces the adjustment.
