Assignment

In this assignment, you are expected to:

• Use a computing tool (e.g. Excel/Google Spreadsheets or Python) for financial calculations. ?
• Use a financial information system (e.g. Reuters Eikon, or the Internet) for obtaining market data and information as well as harnessing well-documented API/library/models to make inferencing more expedient.

Question 1

The term structure is a basic device that provides a snapshot of the interest rate environment in terms of borrowing costs across terms.

(a) Describe how the term structure is constructed starting from a set of yields of par bonds across terms.

(b) Do the following exercises. Be sure to express your answers clearly in your own words, based on your own understanding, with Python as an aid in your calculations and reasoning.

Exercise 1)

Calculate the 2-year, 3-year and 4-year zero-coupon yields and discount factors consistent with the following bonds. The 1-year yield is 10.00%.

Maturity	Coupon	Price
2 years	9.0% (annual)	97.70
3 years	7.0% (annual)	90.90
4 years	11.0% (annual)	99.40

What are the 1-year v 2-year, 2-year v 3-year and 3-year v 4-year forward-forward yields?

Exercise 2)

The forward-forward curve is as follows:

1-year yield:	8.00%
1-year v 2-year:	8.24%
2-year v 3-year:	9.00%
3-year v 4-year:	9.50%

a) Calculate the 2-year, 3-year and 4-year zero-coupon yields and par yields.

b) What is the yield to maturity of a 4-year 12% annual coupon bond, consistent with the rates above?

Question 2

The interest rate parity is a fundamental notion that is applied to relate exchange rates with interest rates.

(a) Describe the relationship between exchange rates and interest rates in the interest rate parity.

(b) Do the following exercises. Be sure to express your answers clearly in your own words, based on your own understanding, with Excel as an aid in your calculations and reasoning.

Exercise 1)

The EuroSterling interest rate for 1 year (exactly 365 days) is 6%. The EuroSwiss Franc interest rate for the same period is 3%. The spot rate today is GBP/CHF 1.3580 / 90.

What would you expect the GBP/CHF swap price to be for 1 year forward? (ignore the buy-sell spread and calculate the middle price only.)
Exercise 2)

	Spot	3-month forward swap
USD/SGD	1.2340 / 45	29 / 32
USD/CAD	0.9720 / 40	46 / 59
GBP/USD	1.6490 / 00	268 / 265

Based on the prices above, what are the two-way prices for?

a. CAD/SGD spot? Which side does the customer buy SGD?
b. GBP/CAD spot? Which side does the customer sell GBP?
c. USD/CAD 3 months forward outright?
d. GBP/USD 3 months forward outright?
e. GBP/CAD 3 months forward outright? Which currency has higher interest rates?
f. CAD/SGD 3 months forward outright? Which currency has higher interest rates?
g. CAD/SGD 3 months forward swap?

Question 3

The equity option market is closely linked to the stock market but at the same time it is structurally different from the latter.

(a) Describe three significant features of the option market that distinguish it from the stock market and two ways that the two markets are closely linked.

(b) Do the following exercises. Be sure to express your answers clearly in your own words, based on your own understanding, with Python as an aid in your calculations and reasoning.

Exercise 1)

What is the estimated annualised volatility of the GBP/USD exchange rate, based on the following daily data, assuming the usual lognormal probability distribution for relative price changes and 252 days a year?

Day 1	1.6320
Day 2	1.6410
Day 3	1.6350
Day 4	1.6390
Day 5	1.6280
Day 6	1.6300
Day 7	1.6250
Day 8	1.6200
Day 9	1.6280
Day 10	1.6200

2) Construct a three-step binomial tree to calculate a price for a 3-month put option on an asset at a strike price of 101. The current price is 100. At each step, the price either rises or falls by a factor of 2% (that is, either multiplied by 1.02 or divided by 1.02). The risk-free interest rate is 12% per annum.

Question 4

Show your workings clearly with calculations performed with Excel.

Augustin manages bonds in the fixed income arm of a private equity company. He holds a portfolio of the following bonds:

Bond	Coupon Rate	Maturity	Number of bonds
A	4.5%	0.5 year	500
B	5.5%	1 year	750
C	6.5%	1.5 years	1000
D	5%	2 years	600

Augustine collects the following data on government bonds:

Maturity	Coupon rate	Yield
0.5 year	0%	3%
1 year	0%	3%
1.5 years	3%
2 years	5%

Assume that every bond in question has a face value of SGD 1000 and pays coupons semi-annually, and the 1.5y and 2y government bonds are issued at par.

(a) Compute all the discount factors from the information given.

(b) Calculate the current value of Richard's bond portfolio.

Show your workings clearly with calculations performed with Excel.

Question 5

Show your workings clearly with calculations performed with Python.

Answer the following questions on option pricing.

(a) Suppose that a call option and a put option have the same characteristics (i.e. same underlying, strike price and time-to-maturity) and are European. Describe, using a graph, the payoff of the position in which the call option is long and the put option is short.

(b) Suppose that the stock price of a company X is currently USD 200, has a volatility of 30% and the prevailing risk-free rate is 2%. Find, by applying the Black-Scholes formula, the price of an at-the-money put option that matures in 3 months. Who in the financial market would quote an option price this way?

(c) Suppose that the stock price of a company Y is currently USD 250, has a volatility of 25% and the prevailing risk-free rate is 2.5%. What is the hedging position in the stock for an option writer who has sold an at-the-money 6-month call option 3 months ago?

Show your workings clearly with calculations performed with Python.
