Definitions


In a swap, two counterparties agree to a
contractual arrangement wherein they agree to
exchange cash flows at periodic intervals.
There are two types of interest rate swaps:

Single currency interest rate swap


Cross-Currency interest rate swap

14-3
“Plain vanilla” fixed-for-floating swaps are often just called
interest rate swaps.
This is often called a currency swap; fixed for fixed rate debt
service in two (or more) currencies.
Size of the Swap Market

In 2007 the notational principal of:
Interest rate swaps was $271.9 trillion USD.
Currency swaps was $12 trillion USD

The most popular currencies are:

The Swap Bank
A swap bank is a generic term to describe
a financial institution that facilitates
swaps between counterparties.
 The swap bank can serve as either a
broker or a dealer.



14-5
As a broker, the swap bank matches counterparties but
does not assume any of the risks of the swap.
As a dealer, the swap bank stands ready to accept either
side of a currency swap, and then later lay off their risk,
or match it with a counterparty.
Swap Market Quotations


Swap banks will tailor the terms of interest rate
and currency swaps to customers’ needs
They also make a market in “plain vanilla” swaps
and provide quotes for these. Since the swap
banks are dealers for these swaps, there is a bidask spread.
14-6
The convention is to quote against U.S. dollar LIBOR.

A

B
5.50% LIBOR + .20%
Firm A wants finance an interest-rate-sensitive asset and
therefore wants to borrow at a floating rate.
A has good credit and can borrow at LIBOR
Firm B wants finance an interest-rate-insensitive asset and
therefore wants to borrow at a fixed rate.
B has less-than-perfect credit and can borrow at 5.5%
The swap bank quotes 5.1—5.2 against dollar LIBOR for a
3-year swap.

Risks of Interest Rate

Basis Risk

Interest rates might move against the swap bank after it
has only gotten half of a swap on the books, or if it has
an unhedged position.
If the floating rates of the two counterparties are not
pegged to the same index.
Exchange rate Risk


In the example of a currency swap given earlier, the
swap bank would be worse off if the pound appreciated.
Risks of Interest Rate
and Currency Swaps (continued)

Credit Risk


Mismatch Risk


This is the major risk faced by a swap dealer—the risk
that a counter party will default on its end of the swap.
It’s hard to find a counterparty that wants to borrow the
right amount of money for the right amount of time.
Sovereign Risk

14-38
The risk that a country will impose exchange rate
restrictions that will interfere with performance on the
swap.
Pricing a Swap


A swap is a derivative security so it can be priced
in terms of the underlying assets:
How to:



14-39
Any swap’s value is the difference in the present values
of the payment streams that are incoming and outgoing.
Plain vanilla fixed for floating swaps get valued just like
a pair of bonds.
Currency swap gets valued just like two nests of
currency forward contracts.
Swap Pricing Example
A currency swap has a remaining life of 18 months.
It involves exchanging interest at 14% on £20
million for interest at 10% on $30 million once a
year. The term structure of interest rates is currently
flat in both the US. And the U.K. and if the swap
were negotiated today the interest rates exchanged
would be $8% and £11%. All rates were quoted with
annual compounding. The current exchange rate is
$1.65 = £1. What is the value of the swap to the
party paying dollars?

Swap Market Efficiency


Swaps offer market completeness and that has
accounted for their existence and growth.
Swaps assist in tailoring financing to the type
desired by a particular borrower. Since not all
types of debt instruments are available to all types
of borrowers, both counterparties can benefit (as
well as the swap dealer) through financing that is
more suitable for their asset maturity structures.
14-42
Concluding Remarks



The growth of the swap market has been
astounding.
Swaps are off-the-books transactions.
Swaps have become an important source of
revenue and risk for banks
