sir your said that contracts of interest rate futures come based on govt securities of 100, and if the value of contract is like 98 interest is 2 , but havent seen its application in the question /examples in lecture notes? are interest rates given like that in exam?
Interest rates are always given directly as a %. It is the equivalent futures price that is 100 minus the interest rate. So if the interest rate is 2%, then the equivalent futures price would be 98.
All the examples in the lecture notes (that I work through in the lectures) are written in the same way as are the questions in the exam.
