Sir in calculating basis for 2 month futures to pay €393265 it’s given as follows in the book End of April June future is o.6964 Spot (1/1.433) =0.6978 Basis ( 0.0014) But shouldn’t we be using 1/1.439 for spot instead of 2 month forward rate used here Also they have used end of April spot as end of June spot in calculating end of June futures . This is soo confusing
