【正确答案】Borrowing period is 6 months (11 months – 5 months)
Current borrowing cost = $34,000,000 x 6 months/12 months x 4·3% = $731,000
Borrowing cost if interest rates increase by 80 basis points (0·8%) = $34,000,000 x 6/12 x 5·1% = $867,000
Additional cost = $136,000 [$34,000,000 x 6/12 x 0·8%]
Using futures to hedge
Need to hedge against a rise in interest rates, therefore go short in the futures market.
Borrowing period is 6 months
No. of contracts needed = $34,000,000/ $1,000,000 x 6 months/3 months = 68 contracts.
Basis
Current price (on 1 June 2015) – futures price = total basis
(100 – 3·6) – 95·84 = 0·56
Unexpired basis (at beginning of November) = 2/7 x 0·56 = 0·16
Assume that interest rates increase by 0·8% (80 basis points) to 4·4%
Expected futures price = 100 – 4·4 – 0·16 = 95·44
Gain on the futures market = (95·84 – 95·44) x $25 x 68 = $68,000
Net additional cost = ($136,000 – $68,000) $68,000
Using options on futures to hedge
Need to hedge against a rise in interest rates, therefore buy put options. As before, 68 put option contracts are needed
($34,000,000/$1,000,000 x 6 months/3 months).
Assume that interest rates increase by 0·8% (80 basis points) to 4·4%

(*The put option is exercised, since by exercising the option, the option holder has the right to sell the instrument at 95·50 instead of the market price of 95·44 and gain 6 basis points per contract. The call option is not exercised, since by not exercising the option, the option holder can buy the instrument at a lower market price of 95·44 instead of the higher option exercise price of 96·00)
