Certain derivative
instruments, such as forwards and
options, provide for the
purchase or sale of some underlier.
In many cases, parties to such derivatives don't want to physically
deliver or receive the underlier. Instead, they enter into the derivative
contract for purely financial reasons.
For example, an airline might enter into an
OTC option contract to
hedge its cost of jet
fuel. It has established dealers from whom it purchases fuel, so it
doesn't want to take actual delivery of fuel under the option contract.
Instead, it negotiates for the option to be cash settled—should it
exercise the option, the counterparty will not delver fuel in exchange for
payment. It will instead pay the airline the option's
intrinsic value. In this
manner, the airline is protected against rising fuel prices but can
purchase its fuel through its usual dealers.
A derivative instrument is
physically settled if the underlier
is to be physically delivered in
exchange for a specified payment. With cash
settlement, the underlier is not physically delivered. Instead,
the derivative settles for an amount of money equal to what the
derivative's market value would be at maturity/expiration if it were a
physically settled derivative. In the case of a forward, this equals the
notional amount multiplied by the difference between the market price of the underlier at maturity and the forward's
delivery price. In the case of an option, it is the intrinsic
value.
Certain types of derivatives are routinely cash settled
because physical delivery would be inconvenient or impossible. For
example, an option on a basket of stocks, such as the S&P 500, will
generally be cash settled because it would be inconvenient and entail
considerable transaction costs to
deliver all five hundred stocks that comprise that index. An
interest rate cap has
has to be cash settled because the underlier is an interest rate, which cannot be physically
delivered.
In commodity and
energy markets, people informally distinguish between the
physical market and
paper market. The physical market
encompasses all transactions in which there is physical delivery—cash,
spot and physically-settled forward transactions. Paper markets encompass
all derivatives transactions that have cash settlement.
