1. The price of interest rate futures contract is in equilibrium with the current market interest rate. When the interest rate changes, the interest rate futures price will also change.

2. When the interest rate rises, it will lead to an increase in the yield of market products, while if the price of interest rate futures remains unchanged, its yield will decrease accordingly, and the decrease in yield will inevitably lead to a decrease in its price.

3. Similarly, when the interest rate falls, the interest rate futures price will rise.
