Premium or Discount
The premium or discount refers to the deviation of a perpetual swap contract's price from the underlying index price. When the contract trades at a higher price than the index, it is at a premium, indicating bullish sentiment.
When it trades at a lower price, it is at a discount, suggesting bearish sentiment. This gap is the primary driver of the funding rate mechanism.
If the premium is high, the funding rate becomes positive to discourage long positions, while a discount leads to a negative funding rate to discourage short positions. Traders monitor this spread to identify market trends and potential arbitrage opportunities.
It provides immediate insight into the demand for leverage on the long or short side. Understanding whether a market is trading at a premium or discount is essential for predicting future funding rate changes and adjusting trading strategies accordingly.
It is a core metric in derivative market analysis.
