Arjun Industries wants to hedge a Rs 50 crore borrowing for months 6 to 12. The market gives a 6-month rate of 6% p.a. and a 12-month rate of 7% p.a. (simple interest, annualised). Which is the approximate theoretical 6x12 FRA rate, using simple interest on a 360-day basis with 6 months = 0.5 year?

The theoretical 6x12 FRA rate is about 7.77% p.a. Divide the 12-month growth factor 1.07 by the 6-month growth factor 1.03 to get 1.038835, giving 3.8835% for six months, which annualises to 7.77%.

  1. A7.77% p.a.Correct
  2. B8.00% p.a.
  3. C7.00% p.a.
  4. D7.28% p.a.

Explanation

Growth over 12 months = 1 + 0.07 = 1.07. Growth over 6 months = 1 + 0.06 x 0.5 = 1.03. Forward growth = 1.07/1.03 = 1.038835. Subtract 1 = 0.038835; annualise by dividing by 0.5 = 7.767%, i.e. 7.77%. Option 8.00% is the naive 2x7 - 6 subtraction, which ignores compounding of the first period.
