  • 3 Year Maturity, Semi-Annual Coupon, Coupon tied to inflation rate (and is at least 1%), face value = $100
  • Issued at par
  • On the first trading day, price went up to $106 (i.e., 6% premium)
  • Does that mean the expected inflation in the next 3 years is 6% per year??

You can’t tell the expected coupons without knowing the discount rates.

Depends on Coupon & Discount rate (C & r) –> we cannot observe from the market.

We can assume that discount rate can be close to what you can earn from the US treasury bill because HKD is tied to the USD.

Before we can make assumption, we cannot tell anything about the expected inflation. We also have to assume C & r are fixed here too. (Unrealistic hence we cannot say expected inflation in next 3 years is 6% per year.
