you mean bonds paper ? if it is, i think it is not, as the coupon will paid to your investment account according to the coupon payment set for that particular issuance. Unless you pull it out and reinvest. Also, generally, foreign bond paper offers better coupon higher than FD rate. Just the product risk rating is different.

It depends, cos bonds are more interest sensitive & global political & economical factor, if it is in your favor, you will enjoy the upside significantly, unlike FD (lowest risk).

Exchange traded bond?, it's the same, bond paper, debt instrument issued for big corp. funding needs. Just that buying in the capacity of priority or private banking allows bigger chunk like SGD 250,000, thus better pricing compare to retail via exchange, allows smaller chunk like SGD 1,000.
