Zero-coupon interest rate swap.
Quoted in terms of a known fixed cash flow \( N^{FIX} \) or a fixed rate \( R \), where:
\[ N^{FIX} = N \left[ (1+R)^{\alpha(T_{0}, T_{K})}-1 \right] , \]
with \( \alpha(T_{0}, T_{K}) \) being the time fraction between the start date of the contract \( T_{0} \) and the end date \( T_{K} \) - according to a given day count convention. \( N \) is the base notional amount prior to compounding. The floating leg also pays a single cash flow \( N^{FLT} \), which value is determined by periodically averaging (e.g. every 6 months) interest rate index fixings. Assuming the use of compounded averaging the projected value of the floating leg becomes:
\[ N^{FLT} = N \left[ \prod_{k=0}^{K-1} (1+\alpha(T_{k},T_{k+1}) L(T_{k},T_{k+1})) -1 \right], \]
where \( L(T_{i}, T_{j})) \) are interest rate index fixings for accrual period \( [T_{i}, T_{j}] \). For a par contract, it holds that:
\[ P_n(0,T) N^{FIX} = P_n(0,T) N^{FLT} \]
where \( T \) is the final payment time, \( P_n(0,t) \) is the nominal discount factor at time \( t \).
At maturity the two single cashflows are swapped.
