Features : FX Option pricing developing an online capability

Nicolas de Breteuil
Sales manager at Icy SoftwareNicolas de Breteuil looks at the benefits of being able to offer an
electronic Options trading platform and the sort of functionality
it should offer.
Just one month ago, the Bank for
International Settlements published its triennial survey,
accounting world wide FX options daily averages turnover to USD 117
billion traded in April 2004. A mere 195% increase over the 2001
comparable period. Even though part of the gross is reflected by
the USD global weakening, undoubtedly OTC FX options is a growing
business.
Company globalisation with product prices competition, as well as
alternative asset management emergence is giving another dimension
to currency options trading. Every risk is assessed, covered and
none of the FASB 133 or IAS 39 rules will divert its path.
Derivatives knowledge is better spread and shared among the
players. The shift from forward rate price to option structures is
more obvious. FX options providers have well understood where their
interest lies with such a high margin product. Banks are making
lots of efforts to support the buy side on FX options trading by
supplying accounting methodology and discussion with customers
auditors.
During the internet booming years, banks started offering FX spot
trading and gradually included options on their platforms. The main
idea was to give the buy side an alternative way to trade with
them, figuring this would increase their FX business flow. They
considered building in-house or purchasing an existing front end
such as AVT. To be among the first ones to offer this service lots
of them selected the second solution. The main problem was that the
buy side was not seeing any kind of difference between the Bank A
or B spot trading platform, with the only noticeable change being
the banks logo (assuming the bid/ask spread linked to their
corporate rating was equal).
Benefits of an electronic Options trading platform We might
therefore consider what are the real benefits of being able to
offer such an eFX platform? There are several answers. On the banks
side, they can offer the same pricing interface to their sales,
regional offices, non FX specialised department and their
customers, such as institutionals, corporates, hedge funds, high
net worth individuals etc and reduce at the same time all the
processing costs and misleading typing errors.
Over the phone, a 200 k nominal ticket represents the same work
processing amount than a 10 Million one, but does not generate the
same mark up. So which one would you think the bank prefers to
trade?
Thanks to technology and STP (Straight Through Processing)
positions traded generate electronic confirmation, going into the
traders book and directly into the customers account (who can
eventually split it in different accounts). Small nominals can be
directly traded either by customers or sales without any trader
intervention. It also brings more liquidity thanks to higher volume
and a 24/7 access. The trading platforms are not subject to
emotional pressure via competition. Banks can also monitor their
customers platform usage and even propose to them adapted FX
options structures. To benefit from technological advances and
amortize huge development costs, top tier banks are even white
labelling their own solutions to smaller banks via various
formulas, lending new capability to smaller players and being
rewarded by business flows. The larger your flows are the smaller
is your risk and you could end up earning the spread.
On the buy side, you may find fewer advantages. You can at any time
get a tradable price on RFQ basis even if it is not the best one.
You can request as many quote ask you want without bothering.
Supposedly, the trading platform might not know you as well as your
Sales person and which side you are coming for.
Should you opt for a prime brokerage solution like hedge funds are,
you could get transactions with all your chosen counterparties for
ten US dollars processing cost per Million US dollars traded.
Limitations of an electronic trading
solution
An eFX platform certainly offers flexibility but you may find some
limitations. Customers cannot price any kind of FX options package
(especially exotics) on any currency pair or maturity or run some
analytics on its behaviour or re-price them on there own market
data.
If you compare voice services to electronic ones, you end up
appreciating the answers obtained from your sales people, options
specialist or trader, with whom you can very easily trade any kind
of sophisticated structure. Are there any tangible reasons why eFX
platform functionalities and offered products are so limited
Exotic options price calculation is really
the trickiest, tedious and difficult part
To find the answer you have to get a better understanding of the
process. First you need to have a sophisticated enough risk
management system to check the customer credit line availability at
any time and before any trade. Then you have to calculate the price
of the option package you want to trade. Consider a windows Forward
zero cost package including a monthly strip of 10 days windows RKO
over two and a half years with a 5m USD leg nominal, its not an
easy one.
Exotic options price calculation is really the trickiest, tedious
and difficult part as second derivatives risk management is
involved. You have to take into account a great number of
parameters such as currency liquidity, gamma, Vega, over hedge
costs, position replication, volatility structure as well as
traders overall books exposure.
