More than 60 per cent of people questioned by the Democratic Party say the government should reconsider the Hong Kong dollar's peg with the US dollar to fight inflation. The party conducted telephone interviews with 557 people last week, and found 62.1 per cent supported a rethink of the peg due to the strength of the yuan and inflation. When asked to consider the impact on the financial system, the figure dropped to 56.7 per cent. Only 18.7 per cent worried speculators would attack Hong Kong's market. The party said the high percentage of interviewees who chose 'no opinion' options in the survey pointed to a need for the government to explain the impact of changes to the peg, under which the Hong Kong Monetary Authority intervenes if the exchange rate moves beyond a rate of HK$7.75 to HK$7.85 to the US dollar. Authority chief executive Norman Chan Tak-lam and Financial Secretary John Tsang Chun-wah say there are no plans to change the peg. Tsang has said the US credit downgrade will have little impact on Hong Kong. The authority said yesterday that the peg remained appropriate 'given the small and externally oriented nature of the Hong Kong economy'.
