However, interest rates will fluctuate. In order to avoid the big risk caused by interest rate fluctuation, interest rate futures are introduced. The so-called interest rate futures refer to futures contracts with bond securities as the subject matter, which can avoid the fluctuation of bank interest rates.
The so-called hedging strategy refers to the actual conversion purchasing power or real value of the existing wealth forms, which can be reliably guaranteed at a certain point or for a certain period of time in the future, or even increase a certain value on this basis, and the change and comparison of this value can be measured. Although it is not easy to measure, because there are too many parameters that lead to the change of value, people usually measure and compare whether the existing wealth is preserved based on the inflation rate.
