Solutions

N2.28

There is a margin call if the margin account falls by \$3,000 - \$2,000 = \$1,000.  This will happen if the new price increases to:

(X – \$4.50) × 5,000 = \$1,000

X – \$4.50= \$0.2

X = \$4.70

Therefore, the price has to increase by 20 cents.

Similarly, to withdraw \$1,500 from the account the price has to fall by 30 cents to \$4.20.

N2.29

Futures prices:

Jun                80

Dec                86

To make money, you could long one June futures contract and short one December contract.  In June, Jun futures contract matures and you take delivery of crude oil. To pay for it you can borrow \$80 per bbl. at 5% for 6 months. There are no storage costs for keeping oil for 6 months. In December, Dec contract matures and you sell crude oil for \$86 per bbl. plus you need to pay back the loan with interest.  Interest is equal to:

\$80 × 0.05 × 6/12 = \$2 per bbl.

So, the gain is \$86 - \$80 - \$2 = \$4 per bbl.
