Criticism of the Comparative Advantage Argument

The 4.0% and 5.2% rates available to PQR Corp and RST Corp in fixed rate markets are 5-year rates.

The LIBOR+0.3% and LIBOR+1% rates available in the floating rate market are six-month rates.

RST Corp’s fixed rate depends on the spread above LIBOR it borrows at in the future.

Chance/Brooks 23

The Nature of Swap Rates

Six-month LIBOR is a short-term AA borrowing rate.

The 5-year swap rate has a risk corresponding to the situation where 10 six-month loans are made to AA borrowers at LIBOR.

This is because the lender can enter into a swap where income from the LIBOR loans is exchanged for the 5-year swap rate.

Forward Rate Agreement

Forward Rate Agreement (FRA) is an agreement where interest at a predetermined rate, RK is exchanged for interest at the market rate.

An FRA can be valued by assuming that the forward interest rate is certain to be realized.

Example: FRA ValuationSuppose that the three-month LIBOR rate is 5% and the six-month LIBOR rate is 5.5% with continuous compounding. Consider an FRA where you will receive a rate 7% measured with quarterly compounding, on a principal of $1 million between the end of month 3 and the end of month 6. The forward rate is 6% percent with continuous compounding or 6.0452 with quarterly compounding. The value of the FRA is$1,000,000 x (.07– .060452) x 0.25 x e-0.055 x 0.5 = $2,322

Chance/Brooks 34

Valuation of an Outstanding Interest Rate Swap

An interest rate swap is worth zero, or close to zero, when it is initiated. After it has been in existence for some time, its value may become positive or negative.

Interest rate swaps can be valued as the difference between the value of a fixed-rate bond (Bfix) and the value of a floating-rate bond (Bfl).

Alternatively, they can be valued as a portfolio of FRAs.

Chance/Brooks 35

Valuation in Terms of Bonds

The fixed rate bond is valued in the usual way as present value of future cash flows.

The floating rate bond is valued by noting that it is worth par immediately after the next payment date.

Then the value of the swap (VSWAP) is

VSWAP = Bfix - Bfl

Chance/Brooks 36

ExampleSuppose that PDQ Corp pays six-month LIBOR and receives 8% per annum (with semiannual compounding) on a swap with notional principal of $100 million and the remaining payment are in 3, 9, and 15 months. The swap has a remaining life of 15 months. The LIBOR rates with continuous compounding for 3-month, 9-month, and 15-month maturities are 10%, 10.5%, and 11%. The 6-month LIBOR rate at the last payment date was 10.2% (with semiannual compounding). What is the value of the swap?

Chance/Brooks 37

Swap Valuation

Bfix = 4e-0.1x3/12 + 4e-0.105x9/12 + 104e-0.11x15/12

= $98.24 million

Bfl = 5.1e-0.1x3/12 + 100e -0.1x3/12

= $102.51 million

The value of the swap is

VSWAP = $98.24 million - $102.51 million

= - $4.27 million

If PDQ Corp had been paying fixed and receiving floating, the value of the swap would be + $4.27 million.

Chance/Brooks 38

Valuation in Terms of FRAs Each exchange of payments in an interest rate

swap is an FRA. The FRAs can be valued on the assumption that

today’s forward rates are realized. The procedure is as follows:

Calculate forward rates for each of the LIBOR rates that will determine swap cash flows.

Calculate swap cash flows assuming that the LIBOR rates will equal the forward rates.

Set the swap value equal to the present value of these cash flows.

Chance/Brooks 39

Swap Valuation as FRAsConsider again the situation in the previous example. The cash flows that will be exchanged in 3 months have already been determined. A rate of 8% will be exchanged for 10.2%. The value of the exchange to PDQ Corp is

0.5 x 100 x (0.08 - 0.102) e-0.1 x 3/12 = -1.07To calculate the value of the exchange in 9 months, we first calculate the forward rate corresponding to the period between 3 and 9 months:

[.105 x .75 –.10 x .25]/.5 =.1075 or 10.75%.

Chance/Brooks 40

Swap Valuation as FRAs

Using the equation

Rm = m(eRc/m – 1)

where Rc is the rate of interest with continuous compounding and Rm is the equivalent rate with compounding m times per annum, we convert 10.75% with continuous compounding into 2 x (e.1075/2 – 1) = .11044 or 11.044% with semiannual compounding.

Chance/Brooks 41


The value of the FRA corresponding to the exchange in 9 months is therefore0.5 x 100 x (0.08 - 0.11044) e-0.105 x 9/12 = -1.41

To calculate the value of the exchange in 15 months, we first calculate the forward rate corresponding to the period between 9 and 15 months. This is

[.11 x 1.25 –.105 x .75]/.5 =.1175 or 11.75%.This value becomes 12.102% with semiannual compounding.

Chance/Brooks 42


The value of the FRA corresponding to the exchange in 15 months is therefore

0.5 x 100 x (0.08 - 0.12102) e-0.11 x 15/12 = -1.79

The total value of the swap is

-1.07 – 1.41 – 1.79 = -$4.27 million

Exchange of Principal

In an interest rate swap the principal is not exchanged.

In a currency swap the principal is usually exchanged at the beginning and the end of the swap’s life.

Chance/Brooks 46

An Example of a Currency Swap

An agreement to pay 11% on a sterling principal of £10,000,000 & receive 8% on a US$ principal of $15,000,000 every year for 5 years.

Valuation of Currency Swaps Like interest rate swaps, currency swaps can be

valued either as the difference between two bonds or as a portfolio of forward contracts.

If we define VSWAP as the value in US dollars of aswap where dollars are received and a foreign currency is paid, then

VSWAP = BD – S0BF

where BF is the value, measured in foreign currency, of the foreign-denominated bond underlying the swap, BD is the value of the US dollar bond underlying the swap, and S0 is the spot exchange rate (expressed as number of units of domestic currency per unit of foreign currency).

Chance/Brooks 55

Example

Suppose that the term structure of interest rate is flat in both Japan and US at 4% and 9% per annum, respectively (both with continuous compounding). ABM Corp has entered into a currency swap to receive 5% per annum in yen and pay 8% per annum in dollars once a year. The principals in two currencies are $10 million and 1,200 million yen. The swap will last for another three years, and the current exchange is 110 yen = $1. What is the value of the swap in dollars?

Chance/Brooks 56

Swap ValuationBD = 0.8e-0.09x1 + 0.8e-0.09x2 + 10.8e-0.09x3

BF = 60e-0.04x1 + 60e-0.04x2 + 1,260e-0.04x3

= 1,230.55 million yen

The value of the swap in dollars is

1,230.55/110 – 9.644 = $1.543 million

If ABM Corp had been paying yen and receiving dollars, the value of the swap would have been -$1.543 million.

Chance/Brooks 57

Currency Swap as FRAsConsider the situation in the previous example. The current spot rate is 110 yen per dollar, or 0.009091 dollar per yen. Using the equation

F0 = S0e (r - rf)T

we calculate the one-year, two-year, and three-year forward rates as

0.009091e(.09 - .04) x 1 = 0.0095570.009091e(.09 - .04) x 2 = 0.0100470.009091e(.09 - .04) x 3 = 0.010562

Chance/Brooks 58

Currency Swap as FRAs

The exchange of interest involves receiving 60 million yen and paying $0.8 million. The risk-free interest rate in dollars is 9% per annum. The value of the forward contracts corresponding to these exchanges are as follows:

(60 x 0.009557 – 0.8)e -0.09 x 1 = -0.2071

(60 x 0.010047 – 0.8)e -0.09 x 2 = -0.1647

(60 x 0.010562 – 0.8)e -0.09 x 3 = -0.1269

Chance/Brooks 59

Currency Swap as FRAs

The final exchange of principal involves receiving 1,200 million yen and paying $10 million. The value of the forward contract corresponding to the exchange is

(1,200 x 0.010562 – 10)e -0.09 x 3 = 2.0416

The total value of the swap is

2.0416 – 0.1269 – 0.1647 – 0.2071

Chance/Brooks 69

Swaps & Forwards

A swap can be regarded as a convenient way of packaging forward contracts.

The “plain vanilla” interest rate swap consists of a series of FRAs.

The “fixed for fixed” currency swap in consists of a cash transaction & a series of forward contracts.

Chance/Brooks 70

Swaps & Forwards

The value of the swap is the sum of the values of the forward contracts underlying the swap.

Swaps are normally “at the money” initially This means that it costs nothing to enter

into a swap. It does not mean that each forward

contract underlying a swap is “at the money” initially.

Chance/Brooks 71

Credit Risk

A swap is worth zero to a company initially.

At a future time its value is liable to be either positive or negative.

The company has credit risk exposure only when its value is positive.

Chance/Brooks 72

Other Types of Swaps

Floating-for-floating interest rate swaps, amortizing swaps, step up swaps, forward swaps, constant maturity swaps, compounding swaps, LIBOR-in-arrears swaps, accrual swaps, diff swaps, cross currency interest rate swaps, equity swaps, extendable swaps, puttable swaps, swaptions, commodity swaps, volatility swaps……..
