Nature of Swaps
A swap is an agreement to exchange cash flows at specified future times according to certain specified rules
7.3
An Example of a “Plain Vanilla” Interest Rate Swap
An agreement by Microsoft to receive 6-month LIBOR & pay a fixed rate of 5% per annum every 6 months for 3 years on a notional principal of $100 million
Uncertainty about LIBOR receipt at end of reset period (6 months) is resolved at start of the reset period: the start of the 6-month period is the reset date

The Comparative Advantage Argument: for both counterparties desired loan differs from that in which comparative advantage lies
AAACorp (less default risk) absolute advantage in both types AAACorp wants to borrow floating but comp. ad. in fixed BBBCorp wants to borrow fixed but comp. ad. in floating Comparative advantage: interest rate differences are different
Fixed 120 bps, Floating 70 bps Total gain = difference of differences = 50 bps
Fixed Floating
AAACorp 4.00% 6-month LIBOR + 0.30%
BBBCorp 5.20% 6-month LIBOR + 1.00%

The Swap

Each counterparty initially issues debt in which comp. advantage lies then enters into swap to obtain desired debt financing
Total Gain (50 bps) partitioned
Gain = interest rate paid in absence of swap – interest rate paid via swap
AAA gain: (L +.3%) – (L +.05%) = 25 bps BBB gain: 5.2% - 4.95 % = 25 bps

Total Gain (50 bps) partitioned
AAA gain: (L+.3%) – (L+.07%) = 23 bps BBB gain: 5.2% - 4.97% = 23 bps Bank gain: 3.97% - 3.93% = 4 bps
7.16
Criticism of the Comparative Advantage Argument
The 4.0% and 5.2% fixed rates available to AAACorp and BBBCorp are 5-year rates
The LIBOR+0.3% and LIBOR+1% rates available to the same corps. are six-month rates
Floating rate loans have more scope for renegotiation than fixed rate loans
BBBCorp’s fixed rate depends on the spread above LIBOR it borrows at in the future
7.17
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
Swap Rate = Par Yield (N-year)
Used in boot strapping procedure True if swap reset period is 6 months Otherwise, must calculate equivalent
interest rate with semiannual compound. For newly issued float rate Bfloat = 100 For newly issued swap Bfloat = Bfix; swap
rate is the coupon rate of fix rate bond Bfix = 100; thus swap rate = par yield
7.19
Valuation (post-inception) of an Interest Rate Swap
Interest rate swaps can be valued as the difference between the value of a fixed-rate bond and the value of a floating-rate bond
Alternatively, they can be valued as a portfolio of forward rate agreements (FRAs)
7.20
Valuation in Terms of Bonds
The fixed rate bond is valued in the usual way
The floating rate bond is valued by noting that it is worth par immediately after the next payment date
Bfloat = PV ( next payment* + par value ) *next payment is know at start of the reset
period
7.21
Example
Receive 8% and pay floating LIBOR both semiannually on a principal of $100 million
1.25 years to go and next floating payment ($5.1 million) will occur 3 months from now
On last reset date (3 months ago) LIBOR = 10.2% 3-, 9-, 15- month zero rates are 10%, 10.5%, 11%
Swap value = 98.238 −102.505= − 4.267; Why negative?

7.22
Valuation (post-inception) in Terms of portfolio of staggered 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

Float. CF for T=1.25 is -6.051
Infer F pertaining to T=.75 to T=1.25 F = (11%(1.25)+10.5%(.75)) / .5 = 11.75% Convert from cc to semiannual compound. F2 = 12.1% T=1.25: CF = - 100Mx12.1%x.5 = -6.051M

An Example of a Currency Swap
An agreement to pay 5% on a sterling principal of £10,000,000 & receive 6% on a US$ principal of $18,000,000 every year for 5 years
7.27
Exchange of Principal
In an interest rate swap the principal is not exchanged
In a currency swap the principal is exchanged at the beginning and the end of the swap
Difference shows up in swap valuation approach via portfolio of staggered forwards

Typical Uses of a Currency Swap
Conversion from a liability in one currency to a liability in another currency
Conversion from an investment in one currency to an investment in another currency

Comparative Advantage Argument for Currency Swaps
General Electric wants to borrow AUD but comp. ad. in USD
Qantas wants to borrow USD but comp. ad. in AUD.
Precondition for viable swap satisfied!
Comparative advantage: interest rate differences are different
USD: 200 bps; AUD: 40 bps; Total Swap Gain = 160 bps.
USD AUD
General Electric 5.0% 7.6%
Qantas 7.0% 8.0%

Valuation (post-inception) of Currency Swaps
Like interest rate swaps, currency swaps can be valued either as the difference between 2 bonds or as a portfolio of forward contracts
Currency Swap Valuation: difference between 2 bonds approach
Test Bank 7.5
Currency Swap Valuation: portfolios of forwards approach Bank previously entered into a swap: receives
5% in JPY, pays 8% in USD Zero curves are flat: JPY 4%, USD 9% Principals: USD10M, JPY1,200M Current spot = JPY110/USD Swap has 3 years remaining CF exchange occurs annually; a CF exchange
has recently occurred Intuition: Vswap > 0 since JPY R has dropped,
USD R has risen. Also, JPY has appreciated; USD has depreciated since contract signed.

Swaps & Forwards
A swap can be regarded as a convenient way of packaging forward contracts
When a swap is initiated the swap has zero value, but typically some forwards have a positive value and some have a negative value
7.36
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
Credit Risk Exposure of Entity
Vswap to entity
Credit risk exposure only if Vswap > 0
