Qatar's successful launch last week of a $5bn sovereign bond issue despite turbulent global market conditions could trigger further bond offerings as corporate entities in the gas-rich state seek to raise more funds for ambitious infrastructure plans, bankers and analysts say.

Qatar's government raised $5bn in a three-tranche bond deal, the largest from the Gulf region so far this year, after attracting orders of close to $10bn and finding strong demand from Middle East and other investors, bankers who worked on the deal said.
