In terms of recently issued guidelines,
corporates are now allowed to sell
currency options against export
receivables or import pay ables.
Earlier, they could buy options against
their exposures but could not sell.
This would allow the exporter get
upfront income as he receives premium
towards his sale with limited risk as
the option is covered by future receivables
of the exporter.
Also, Indian banks will now be allowed
to run cross currency option books.
Caps and floors are structured
combinations using interest rate options
– both calls and puts. A cap would imply
an upper limit on the interest rate and
floor would be the lower limit. Selling
call options allows a corporate to create a
cap, while buying put options on interest
rates creates a floor for the corporate.
Here the options are linked to a benchmark
reference rate like the LIBOR. Suppose a corporate sells a call option for
$1 million at a strike of 6.50%. If LIBOR
goes below 6.50%, the option holder
would exercise the option, allowing him
to earn a rate that is higher than LIBOR.
This increases the payout for the
corporate, while the LIBOR ensures that
he has a floor of 6.50%. This would be
the minimum amount that he would have
to pay even if interest rates move below
6.50%. Selling call options also helps
reduce the overall transaction cost as the
corporate receives a premium for the sale
of options. Buying put options helps the
corporate create a cap on the highest rate
of interest to be paid out.
Continuing with the previous example,
instead of selling, the client buys put
options at a strike of 6.50%. So, if LIBOR
rises beyond 6.50%, the corporate
exercises the option and pays lower
rates capping his upper limit on interest
rates. Again, the corporate needs to pay a
premium for purchasing the cap. A combination of floors and cap is called
a collar.
