The annual effective spot rates are 4.0% for 1 year and 5.0% for 2 years. What is the price of a 2-year zero-coupon bond with a face value of Rs 100,000, to the nearest rupee?

The price is Rs 90,703. A 2-year zero-coupon bond is discounted at the 2-year spot rate of 5% effective for two years, so 100,000 divided by 1.1025 gives 90,703. The 1-year rate does not apply to this cash flow.

  1. ARs 90,703Correct
  2. BRs 92,456
  3. CRs 96,154
  4. DRs 95,238
  5. Rs 82,270

Explanation

Price = 100,000/(1.05)^2 = 100,000/1.1025 = 90,703. Using the 1-year rate 4% for two years gives 92,456, which is wrong because it ignores the 2-year spot rate.
