China's bond issuance is expected to account for 72 percent of a total of $245.6 billion in Asia next year, said Samantha Xie, China head of debt capital markets at JPMorgan Chase & Co.

As of Dec 14, the bond issuance in Asia had hit a record of $296.4 billion in 2017, with China taking 65 percent of the total. During the same period, high-yield bond issuance tripled to $80.6 billion.

Since the beginning of this year, high-yield bonds issued by Chinese real estate companies have reached nearly $32 billion, and the amount will continue to increase. It will hopefully lead to growth in high-yield bond issuance to $50.4 billion in 2018, Xie said.

She noted that about $35 billion onshore bonds issued by Chinese real estate developers will mature next year, and the majority of them are expected to be refinanced in overseas markets due to rising onshore corporate bond yields.
