Funding Rates

Why Funding Rates Exist

Traditional futures contracts have an expiration date where the contract settles at spot price. Perpetual contracts never expire.

To prevent perpetual contract prices from drifting away from real world spot prices, exchanges implement an automated periodic payment mechanism (usually every 8 hours).

How Payments Flow

1. Positive Funding Rate: Occurs when perpetual prices trade at a premium above spot price (bullish sentiment). Long traders pay short traders a fee to keep positions open.
2. Negative Funding Rate: Occurs when perpetual prices trade at a discount below spot price (bearish sentiment). Short traders pay long traders a fee.

Using Funding Rates as a Market Sentiment Indicator

1. Extreme Positive Funding: Signals overleveraged bullish euphoria. When long traders are paying heavy fees, the market becomes vulnerable to a sudden long squeeze.
2. Extreme Negative Funding: Signals aggressive short positioning. When short traders are heavily crowded, even modest spot buying can trigger massive short squeeze liquidations.
