The counterparties are the two parties that participate in the swap transaction. The terms most used in swap contracts are as follow:<\/p>\n<ul>\n<li><strong>Swap Term (or Swap Tenor):\u00a0<\/strong>An interest rate swap tenor is the period of the swap contract. The swap term can be short, such a few months or longer, as ten years.<\/li>\n<li><strong>Settlement Date:\u00a0<\/strong>The settlement date is the agreed date that the counterparties will exchange the cash flows (interest rate payments).<\/li>\n<li><strong>Settlement Period:\u00a0<\/strong>The settlement period is the length of time between two settlement dates. The settlement periods depend on the agreement of the counterparties. The settlement can be monthly, quarterly, or even shorter periods agreed by the counterparties.<\/li>\n<li><strong>Swap Rate:\u00a0<\/strong>Mostly defined in the interest rate swaps, the swap rate is a fixed interest rate given in an interest swap contract. The swap rate is a fixed interest rate, <em>i<\/em>, that one counterparty demands in exchange for the uncertainty of having to pay the variable rate (floating interest rate) over time.<\/li>\n<li><strong>Floating Interest Rate:\u00a0<\/strong>Also defined in interest rate swaps, the floating interest rate is the basis for computing floating interest payments at each settlement date. Examples of the floating interest rates include LIBOR (London Interbank Offer Rate) and the Treasury Bill Rate. The floating rate is stated with a predetermined spread to the reference rate, such as 1-year LIBOR plus 30 basis points.<\/li>\n<\/ul>\n<h3>General Set-up of a Swap<\/h3>\n<p>By the definition of a swap, one set of payments (level) is \u201cswapped\u201d for another set of payments (non-level, or floating). Consider the following three-period timeline:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-medium wp-image-8987\" src=\"https:\/\/analystprep.com\/study-notes\/wp-content\/uploads\/2020\/01\/SOA_FM_Chapter_7_InterestRatesSwap_Image1-300x195.png\" alt=\"\" width=\"300\" height=\"85\" \/><\/p>\n<p>On the timeline above, the level payment \\(C\\) at each period is swapped with non-level payments,\\(C_k\\) where \\((k=1,2,3)\\). The swap transactions are done in a \u201cfair way.\u201d That is, the present value at time 0 of interest rate payments are equal to each other. Note that swaps are in the context of the term structure of interest rates. Using the timeline above, it implies that:<\/p>\n<p>$$ C_1\\cdot\\ v_1+C_2\\cdot\\ v_2^2+C_3\\cdot\\ v_3^3=C\\cdot\\ v_1+C\\cdot\\ v_2^2+C\\cdot\\ v_3^3 $$<\/p>\n<p>In the equation above, the level payments are usually known. On the other hand, non-level payments are unknown. If we make \\(C\\) the subject of the formula, we have:<\/p>\n<p>$$ C=\\frac{C_1\\cdot v_1+C_2\\cdot v_2^2+C_3\\cdot v_3^3}{v_1+v_2^2+v_3^3} $$<\/p>\n<p>The value given by the equation above is called the <strong>swap price.<\/strong><\/p>\n<p>In a swap contract, there are two counterparties: the payer and the receiver. The payer pays the fixed swap price and receives the non-level payments while the receiver receives the fixed swap price and pays the non-level payments.<\/p>\n<p>The <strong>net swap payment (NSP)<\/strong> is the amount received minus the amount paid. As such, for the payer, the net swap payment at time \\(k\\) is given by:<\/p>\n<p>$$ NSP_K=C_k-C $$<\/p>\n<p>On the other hand, the net swap payment for the receiver at time k is given by:<\/p>\n<p>$$ NSP_K=C-C_k $$<\/p>\n<p>As an example, assume that in the timeline above, the payments are as follows:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-medium wp-image-8988\" src=\"https:\/\/analystprep.com\/study-notes\/wp-content\/uploads\/2020\/01\/SOA_FM_Chapter_7_InterestRatesSwap_Image2-300x176.png\" alt=\"\" width=\"300\" height=\"176\" srcset=\"https:\/\/analystprep.com\/study-notes\/wp-content\/uploads\/2020\/01\/SOA_FM_Chapter_7_InterestRatesSwap_Image2-300x176.png 300w, https:\/\/analystprep.com\/study-notes\/wp-content\/uploads\/2020\/01\/SOA_FM_Chapter_7_InterestRatesSwap_Image2.png 342w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>Therefore, the net swap payment for the payer at time 2 is:<\/p>\n<p>$$ NSP_2=C_2-C=40-50=-10 $$<\/p>\n<p>That is, the payer owes 10 at time 2.

In other words, interest payments are only exchanged. Consider that following illustration:<\/p>\n<h4>Illustration: Interest Rate Swap<\/h4>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-medium wp-image-9028\" src=\"https:\/\/analystprep.com\/study-notes\/wp-content\/uploads\/2020\/01\/SOA_FM_Chapter_7_InterestRatesSwap_Image33.PNG1_-2.jpg\" alt=\"\" width=\"500\" height=\"58\" \/><\/p>\n<p>The diagram above is an interest rate swap between two counterparties A and B.

The notional amount at time \\(k\\), denoted by \\(N_k\\), is the amount of money on which interest amounts are calculated for the following period.<\/p>\n<p>As a matter of emphasis, swaps are transacted in the context of the term structure of interest rates. As such, using the timeline above, from time 0 to time 1, we use a one-year spot rate \\(s_1\\) (equivalent to one-year forward rate from time 0 to time 1) so that the interest amount at time 1 is:<\/p>\n<p>$$ I_1=N_0\\cdot\\ s_1 $$<\/p>\n<p>From time 1 to time 2, we use a one-year forward rate from time 1 to time 2, \\(f_{[1,2]}\\) so that the interest payment at time two is:<\/p>\n<p>$$ {I_2=N}_1\\cdot {f_{[1,2]}} $$<\/p>\n<p>Intuitively, from time two to time three, we use a one-year forward rate from time 2 to time 3, \\(f_{[2,3]}\\) so that the interest payment is:<\/p>\n<p>$$ I_3=N_2\\cdot {f_{[2,3]}} $$<\/p>\n<p>The following timeline summarizes the above interest payments:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-medium wp-image-9021\" src=\"https:\/\/analystprep.com\/study-notes\/wp-content\/uploads\/2020\/01\/SOA_FM_Chapter_7_InterestRatesSwap_Image43.png\" alt=\"\" width=\"500\" height=\"63\" \/><\/p>\n<p>Note that an interest rate swap exchanges a non-flat yield curve for a flat yield curve. As such, notice that the payments above are based on the non-flat yield curve (variable interest amounts). Thus, the payment at time \\(k\\) is swapped with a payment of \\(N_{k-1}.i\\) where \\(i\\) is a fixed interest rate. Therefore, for the timeline above, the fixed interest amounts for times 1, 2, and 3 are \\(N_0.i\\), \\(N_1.i\\) and \\(N_2.i\\) respectively. Consider the following timeline:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-medium wp-image-9017\" src=\"https:\/\/analystprep.com\/study-notes\/wp-content\/uploads\/2020\/01\/SOA_FM_Chapter_7_InterestRatesSwap_Image51.png\" alt=\"\" width=\"500\" height=\"88\" \/><\/p>\n<p>The fixed interest \\(i\\) is called a <strong>swap rate.<\/strong><\/p>\n<p>In the context of the interest rate swaps, the payer pays the fixed-rate and receives the variable interest rate while the receiver receives a fixed interest rate and pays the variable interest rate. Also, recall that the net swap payment is defined as the amount received minus the amount paid. Thus, the net swap payment for the payer at time \\(k\\) is given by:<\/p>\n<p>$$ \\begin{align*} NSP_k&amp;=N_{k-1}\\cdot\\ f_{\\left[k-1,k\\right]}-N_{k-1}\\cdot i\\\\ &amp;=N_{k-1}\\cdot\\left(f_{\\left[k-1,k\\right]}-i\\right) \\end{align*} $$<\/p>\n<p>On the other hand, the net swap payment for the receiver at time \\(k\\) is given by:<\/p>\n<p>$$ \\begin{align*} NSP_k&amp;=N_{k-1}\\cdot\\ i-N_{k-1}\\cdot\\ f_{\\left[k-1,k\\right]}\\\\ &amp;=N_{k-1}\\cdot(i-f_{\\left[k-1,k\\right]}) \\end{align*} $$<\/p>\n<p>Continuing with our timeline example, swaps are usually transacted in a fair way. That is, the present values of the payments at time 0 must be equal. In the case of our interest rate swap illustration, it implies that:<\/p>\n<p>$$ N_0\\cdot\\ f_{\\left[0,1\\right]}\\cdot v_1+N_1\\cdot f_{\\left[1,2\\right]}\\cdot v_2^2+N_2\\cdot f_{\\left[2,3\\right]}\\cdot v_3^3=N_0\\cdot i\\cdot v_1+N_1\\cdot i\\cdot v_2^2+N_2\\cdot i\\cdot v_3^3 $$<\/p>\n<p>If we make \\(i\\) the subject of the formula, we get:<\/p>\n<p>$$ i=\\cfrac{N_0\\cdot f_{[0,1]}\\cdot v_1+N_1\\cdot f_{[1,2]} \\cdot v^2_2+N_2 \\cdot f_{[2,3]} \\cdot v^3_3}{N_0 \\cdot v_1+N_1 \\cdot v^2_2+N_2 \\cdot v^3_3} $$<\/p>\n<p>Note that the notional amount needs not be equal at each period.

We shall base our discussion on the interest rate swaps, which is the main aim of the chapter.

Lastly, it important to note that the market values of the counterparties in an interest rate swap have the same absolute value (but opposite signs).<\/p>\n<h4>Example: Market Value of an Interest Rate Swap<\/h4>\n<p>Beth has a four-year variable rate loan of 1,000, where the interest rate is reset annually to the one-year spot interest rate.
