Supply and demand for forwards and futures will determine their market prices.
BUTThe forwards and futures markets
are NOT independent of the spot market.
If spot and futures prices do not maintain A SPECIFIC relationship, dictated by economic rationale, then, arbitragers will enter these markets. Their activities will tend to force the prices to realign.

Demand and Supply of futures by:Long and Short Hedgers
Long and Short SpeculatorsAnd then,
the Arbitrageurs activities in the spot
and futures markets.

• Arbitrage: A market situation whereby an
investor can make a profit with: no equity and no risk.
• Efficiency: A market is said to be efficient if
prices are such that there exist no arbitrage opportunities.Alternatively, a market is said to be inefficient if prices present arbitrage opportunities for investors in this market.

ARBITRAGE WITH FUTURES:Arbitragers trade in both, the futures and the spot markets simultaneously. Then, they wait until delivery time and close their positions in both markets.Note: their profit is guaranteed when open their positions.

Valuing a Forward Contract(Page 107)
For the sake of comparison: K = Ft,T is the forward price today ,t , for
delivery at T. At a later date, j, F0 = Fj,T.
ƒj , is the forward value at any time j; t ≤ j ≤ T.
Date: t j T

26
Valuing a Forward Contract(p.108)
Again:• Suppose that, Ft,T is forward price
today ,t , for delivery at T and Fj,T is the forward price at date j, for delivery at T.
• At j, t ≤ j ≤ T, the value of a long forward contract, ƒj[L], is
fj[L] = (Fj,T – Ft,T )e–r(T-j)

Forward vs Futures Prices• Forward and futures prices are
usually assumed to be the same. When interest rates are uncertain they are, in theory, slightly different:
• A strong positive correlation between interest rates and the asset price implies the futures price is slightly higher than the forward price
• A strong negative correlation implies the reverse
![Page 29: PowerPoint Presentation€¦ · PPT file · Web view · 2008-03-26Determination of Forward and Futures Prices Chapter 5 The participants HEDGERS: OPEN FUTURES POSITIONS IN ORDER](https://reader035.fdocuments.us/reader035/viewer/2022070609/5adadd697f8b9afc0f8d14a4/html5/thumbnails/29.jpg)

Stock Index (P. 111)
• Can be viewed as an investment asset paying a dividend yield
• The futures price and spot price relationship is therefore
F0,T = S0e(r–q )T
where q is the dividend yield on the
portfolio represented by the index
![Page 30: PowerPoint Presentation€¦ · PPT file · Web view · 2008-03-26Determination of Forward and Futures Prices Chapter 5 The participants HEDGERS: OPEN FUTURES POSITIONS IN ORDER](https://reader035.fdocuments.us/reader035/viewer/2022070609/5adadd697f8b9afc0f8d14a4/html5/thumbnails/30.jpg)
30
Stock Index (continued)
• For the formula to be true it is important that the index represent an investment asset
• In other words, changes in the index must correspond to changes in the value of a tradable portfolio
• The Nikkei index viewed as a dollar number does not represent an investment asset

31
Stock Index ArbitrageWhen F0,T > S0e(r-q)T
an arbitrageur buys the stocks underlyingthe index and sells futures.
When F0,T < S0e(r-q)T
an arbitrageur buys futures and shorts orsells the stocks underlying the index.

32
Index Arbitrage • Index arbitrage involves
simultaneous trades in futures and many different stocks
• Very often a computer is used to generate the trades
• Occasionally (e.g., on Black Monday) simultaneous trades are not possible and the theoretical no-arbitrage relationship between F0,T and S0 does not hold

• A foreign currency is analogous to a security providing a dividend yield
• The continuous dividend yield is the foreign risk-free interest rate
• It follows that if rf is the foreign risk-free interest rate

Example:The six-months rates in the USA and
the EC are 4% and 7%, respectively. The current spot exchange rate is:S(USD/EUR) = USD1.49/EUR.
The no arbitrage six-months forward rate is:F(USD/EUR) = 1.49e –[.04 - .07](.5) F(USD/EUR) = USD1.5125185/EUR
If the Forward market rate is other than the above, arbitrage is possible.

With these market realities, a new no-arbitrage condition emerges:
BL < FBID < FASK < BU
As long as the futures price fluctuates between the bounds there is no possibility to make arbitrage profits

Example 1:S0,BID (1 - c)[1 + f(rBID )] < F0, T < S0,ASK (1 + c)(1 + rASK)
c is the % of the price which is a transaction cost.Here, we assume that the futures trades for one price.In order to understand the LHS of the inequality, remember that in the USA the rule is that you may invest only a fraction, f, of the proceeds from a short sale. So, in the reverse cash and carry, the arbitrager sells the asset short at the bid price. Then (1-f)S0,BID cannot be invested. Only fS0,BID is invested. Thus, the inequality becomes:
F0,T (1-f)(1-c)S0,BID + fS0,BID(1-c)(1+rBID)
F0,T S0,BID(1-c)(1 + frBID)

S0,BID(1-c)[1+f(rBID )]< F0,T< S0,ASK(1+c)(1+rASK)

EXAMPLE 1. $87.5425 + f($7.0034) < F0,T < $104.4008THE CASH-AND-CARRY costs: $104.4008/bbl. THE REVERSE CASH-AND-CARRY costs:87.5425+ f($7.0034). IF f=0.5 the lower bound of the futures becomes: $91.0042. In the real market, f = 1, for some large arbitrage firms and thus, for these firms the lower bound is: $94.5459.

Example 2: THE INTEREST RATES PARITY
In the real markets the forward exchange rate fluctuates within a band of rates without presenting
arbitrage opportunities.Only when the market forward exchange rate diverges from this band of rates
arbitrage exists.Given are:
Bid and Ask domestic and foreign spot rates; forward rates and interest rates.

A numerical example:
Given the following exchange rates:
Spot Forward Interest ratesS(USD/NZ) F(USD/NZ) r(NZ) r(US)
ASK 0.4438 0.4480 6.000% 10.8125% BID 0.4428 0.4450 5.875% 10.6875%
Clearly, F(ask) > F(bid). (USD0.4480NZ > USD0.4450/NZ)
We will now check whether or not there exists an opportunity for arbitrage profits. This will require comparing these
forward exchange rates to: BU and BL
