Frenzied dealing in stocks and property means this year's Budget surplus will be in excess of $25.5 billion. The figure is more than 15 times the surplus estimated by Financial Secretary Donald Tsang Yam-kuen in his debut Budget last March. Mr Tsang had forecast a very modest $1.6 billion surplus for the current financial year. About $16 billion of the surplus 'bonus' is expected to come from stamp duty on stocks and property transactions, at least 160 per cent up on the previous year. The remaining $9.5 billion comes from land revenues. In his estimates for total government revenue, Mr Tsang had predicted $10.4 billion would be raised through stocks and property stamp duty. However, this did not take into account the stocks and property bonanza which has pushed the surplus back up to the record levels of 1991 and 1992. Up to the end of January, stamp duty collected in both areas had risen to about $22.7 billion. Assuming transactions for February and March retained the momentum of the previous six months, duty collected should have pushed the total up to a massive $26.4 billion - thus providing Mr Tsang's $16 billion surplus. Land revenue, another volatile source of government income, comes mainly from public auctions and tenders, private treaty grants and premiums for land exchanges and changes of land use. This year's should be more than $46 billion, about $9.5 billion more than the original Budget estimate. Director of Lands Robert Pope has already confirmed the amount raised would be significantly higher than originally estimated. Tim Lui Tim-leung, president of the Hong Kong Society of Accountants, said the financial situation was healthy. The Special Administrative Region government should make use of the reserves to develop industries that were vital for Hong Kong to maintain its status as a business and commercial centre, he said.
