Hong Kong Monetary Authority (HKMA) chief executive Joseph Yam Chi-kwong is still undecided on whether to attend the annual meetings of the International Monetary Fund and World Bank Group in 10 days' time in Washington. His indecision has created anxiety in the local banking and investment communities, which have urged the Government to reassure the international community about its massive intervention in the domestic equity and futures markets in August. The authority's deputy chief executive, David Carse, would not explain yesterday why Mr Yam had delayed his decision about going, saying only that the HKMA's delegation list of attendees at the meetings had not been finalised. Ten days ago, Financial Secretary Donald Tsang Yam-kuen said he would leave this Sunday for a three-week roadshow covering cities in Europe and the United States. This will include attending the IMF and World Bank annual meetings. Chief Executive Tung Chee-hwa's office said Mr Tung would not attend the meetings. One banker, who declined to be named, said he would be very disappointed if Mr Yam did not attend the meetings because Hong Kong urgently needed to provide the international community with a thorough understanding of its intervention, which in many eyes had undermined Hong Kong's reputation as the world's freest economy. He said Mr Yam, as the man who supervised the August 14-28 intervention, which market players estimate to have cost up to $120 billion, would be the best person to explain the move to attendees of the IMF and World Bank meetings, which include many of the world's most influential financial figures. Last September at the annual meetings of the two supranational entities held in Hong Kong, the authority played an active role.
