Video summary
This video introduces derivative products within international finance, beginning with an explanation of the Black-Scholes formula used to calculate theoretical option prices. The formula primarily applies to European-style options, which can only be exercised at their expiration date, under the assumption that markets operate efficiently. To determine an option's price, the model relies on five key variables: the strike price, the current stock price, the time remaining until expiration, the risk-free interest rate, and the volatility of the underlying asset. These components work together to provide a precise estimate of what an option is worth in the real market.
The discussion then shifts to financial futures, highlighting their unique characteristic as zero Net Present Value contracts that are continuously marked to market based on current fair values. This marking-to-market process makes futures contracts highly effective instruments for hedging against price fluctuations. The video explains that by examining these contracts, investors can analyze the potential gains and losses resulting from changes in the underlying asset's price. Furthermore, the segment contrasts futures with interest rate swaps, noting that while futures are often shorter-term, interest rate swaps typically operate over a longer horizon to help reduce interest rate risk and uncertainty for borrowers.
Interest rate swaps are described as over-the-counter derivatives involving two parties who exchange cash flows on a periodic basis; one party receives fixed payments while the other pays floating rates linked to a benchmark like LIBOR. The primary benefits of these swaps include lowering the cost of loans and mitigating interest rate risk, thereby reducing overall financial uncertainty. Following this, the video examines currency swaps, which involve two parties exchanging different currencies at an agreed-upon spot rate initially and then re-exchanging them at a future date using a predetermined forward rate. These contracts effectively combine a spot transaction for immediate delivery with a forward transaction for future settlement.
Finally, the video concludes by outlining the significant advantages of currency swaps, emphasizing that they are inherently riskless in nature when structured correctly. By utilizing these instruments, investors can leverage funds held in one specific currency to meet obligations denominated in another currency without exposing themselves to adverse exchange rate movements. This mechanism allows participants to hedge foreign exchange risks effectively, eliminating uncertainty for investors who wish to utilize their current assets to fund international liabilities safely. The session ends with an encouragement for viewers to research further on the benefits of financial futures before meeting again next week.

welcome back everyone this week we're
going to look at derivative products
what we're going to do we'll look at the
Block shs formula then we'll look at the
payoffs of a financial future and at the
same time we'll have a look at the
benefits of interest rate swaps and then
we'll examine the nature of currency
swaps now first things first if we want
to look at the black schs formula
basically the black shs formula is used
to calculate option prices and the way
that it does that is basically by
providing a theoretical estimate of the
price of options now these options
normally are European style options and
here the formula basically assumes that
an option is only
exercisable at its expiration date and
at the same time there is another
assumption that markets are acting
efficiently and so these basically are
the three main conditions associated
with applying the black shs formula when
we are trying to find out the price of
an option now while doing that when we
want to calculate the price of an option
and find out what is the price of an
option we look at five different
variables within the formula so the
first variable is basically the strike
price and the strike price is basically
the asset price when the option was
exercised now the other VAR iable is the
current price of the stock the third
variable here is the time to expiration
the fourth one is basically the
risk-free rate and finally we look at
the volatility of the option now having
all of these would allow us basically to
calculate the uh option price and find
out what the real option price looks
like and as we discussed we we will also
be looking at the payoffs of financial
Futures and for us what is important is
that to see and to examine the different
gains and losses that could occur um due
to changes in the underlying price of
the asset and because of this we look at
Future contracts and the future
contracts basically are zero Net Present
Value contracts and in that sense uh
future contracts are normally marked to
Market which makes them a good
instrument for hedging now what does
Mark to market mean basically Mark to
market is when we look at the value of
the asset price based on its current
market pricing or based on its fair
value now on the other hand if we want
to look at interest rate swaps and if we
want to examine some of the benefits of
interest rate swaps first of all we need
to look at what it means and interest
rate swaps are instruments that normally
are overthe counter derivatives and
these kind of derivative
contracts are between two different
parties so you have one party here that
receives a fixed amount of a fixed
amount on a periodical basis and the
other party basically provides a Liber
linked floating payments now normally
interest rate swaps what they do they
help in reducing interest rate risk and
by doing so they also help reduce
uncertainty now what they do also they
can help reduce the cost of loans and as
a result these interest rate swaps or
these kinds of instruments they have a
longer Horizon than financial Futures
next thing we're going to do is
basically examine the nature of currency
swaps now currency swaps are basically
contracts where you have two different
parties exchanging two different
currencies and these two different
currencies are basically exchanged at a
particular rate and then after that they
go ahead and re-exchange uh the
currencies back again at a different
rate that they also agree on but the
difference is the re exchange happens at
a fixed date in the future now here as
you can imagine the currency swap trade
is basically composed of two different
transaction the first transaction is a
spot transaction while the other
transaction is basically a forward
transaction in terms of the spot
transaction here what we have a
purchasing and so buying and selling of
a particular currency for an immediate
or perhaps a near immediate delivery and
payment on the other hand when we're
talking about the forward transaction
here what we're talking about is
basically the buying and selling of a
currency at a specific date in the
future now why do we look at currency
swaps so what are the benefits of
looking or what are the benefits of
currency swaps basically they are
riskless in nature and so here investors
can benefit from using the funds that
they have today in a specific currency
to basically fund obligations that are
dominated in another currency at the
same time while they are doing this they
are able to hedge foreign exchange risks
and as you can see it eliminates risk in
a way or another for investors now with
all of this with everything that we've
discussed today perhaps it would be a
good idea for you to go and do a little
bit of research and find out what are
some of the benefits of financial
Futures while you do this I'll wait for
you and we'll have a chat next week
