Non-marketable bond refers to a bond that cannot be sold between investors. An example of a non-marketable bond would be canada savings bonds. the federal government issues non-marketable canada savings bonds to canadian residents only, and Isuspect the way they can control this is by issuing non-marketable bonds that cant be sold to third parties by the canadian residents who originally purchased them. The one advantage of buying this type of bond is that the lack of a secondary market means there wouldnt be any concern over price changes to the bond (since there is no market where a price can be established).
