RT. Inflation-linked bonds are bonds where the principal is indexed to inflation.Originally these bonds are designed to provide protection against inflation, serving to minimize inflation risk. The most typical Inflation-Linked bonds though the market are:

• the Canadian "Real Return Bond "(RRB)
• the British "Inflation-linked Gilt" (ILG) and
• the new U.S. Treasury "inflation-protected security" (IPS)
  

Besides hedging against inflation, my personal idea to use these bonds are to trade inflation via two opposite trades:

Long(or short) inflation-lined bonds (let's say Gilt)

Short(or long)  ordinary British Government bonds

Then you are exposed exclusively to the UK Inflation. However, this idea may be not practical, since trading inflation is hard and the liquidity is limited.

I will upload a more technique guide to these Bonds given by J.P. Morgan in the following days.
