Hutchison Whampoa, one of the most active issuers this year, has won the best credit rating in the Asian US dollar fixed-income market, according to a survey of 200 bond investors globally by The Asset, a financial magazine published in Asia. Rating pressure had been haunting Hutchison due its third-generation mobile-phone business while its bonds had been trading cheaply, with a BBB credit rating. Investors are now, however, more comfortable with the company's debt because its other businesses generate more stable and predictable returns. The ports-to-telecoms conglomerate has been given an A-minus credit rating by Standard & Poor's. So far this year, the company has raised US$6.4 billion in the international bond market. Following Hutchison were Malaysian state-owned oil company Petronas and Korea Development Bank. The former has a credit rating of BBB plus while the latter an A-minus from Standard & Poor's.
