Norman Chan Tak-lam becomes the boss of his former boss, Joseph Yam Chi-kwong, the chief executive of the Hong Kong Monetary Authority ... Does it sound unbelievable? But what of the chain of events should rumours of Mr Chan's new job as financial secretary be confirmed? When Mr Chan quit his job in April as HKMA deputy chief executive to prepare for his going to Harvard University in September, White Collar reported that his departure was linked to the election bid by Donald Tsang Yam-kuen. This has proved to be true, with Mr Chan taking a summer holiday job helping Mr Tsang's campaign for election as chief executive. Speculation is now rife that Mr Chan will still go Harvard to study but will return to join the government as financial secretary if Henry Tang Ying-yen departs. If that happens, Mr Yam may need to report to Mr Chan, but this does not diminish his position as the world's highest-paid central banker with an annual pay package of $9.5 million - more than three times what the financial secretary earns. Just as the election outcome seems set, so does the reshuffle of supporting roles in the financial sector - former secretary for financial services Rafael Hui Si-yan's elevation to chief secretary looks assured. Mr Chan's role can be flexible after his nine-month course. He can be financial secretary, replace Mr Yam at the de facto central bank, succeed Frederick Ma Si-hang as secretary for financial services and the treasury, or become the first chief executive of the Securities and Futures Commission if the government splits Andrew Sheng's role into a non-executive chairman and chief executive. Hong Kong Exchanges and Clearing chairman Charles Lee Yeh-kwong is tipped to cross the road to Chater House to become the SFC's first non-executive chairman in April next year. Mr Lee will stay on as the chairman of the Mandatory Provident Fund Schemes Authority where Mr Chan's wife Diana is managing director. And HKEx chief executive Paul Chow Man-yiu is likely to team up with Marvin Cheung Kin-tung, who is tipped to become HKEx chairman. So Mr Tsang is likely to have close allies in high places in the financial world, perhaps the only exception being Mr Ma, who is seen as an intimate of former financial secretary Antony Leung Kam-chung - hardly a close friend of Mr Tsang. The market is now watching Mr Ma for his next move. Like the other ministers, he will keep the title but will no longer attend all Executive Council meetings. angry man is forgiving Mr Tsang would also face an old rival in the Legislative Council - Chim Pui-chung, who represents the broker sector. 'Angry Man' Chim was hoping to gain the 100 nominations needed to be a chief executive candidate, but his hopes were dashed after all 12 broker representatives on the Election Committee decided to back Mr Tsang. But Mr Chim holds no grudges. 'Everything is forgiven,' one broker on the committee said. 'Mr Chim understands why the 12 voters of his sector made such a decision. 'It is not about abandoning him but the broker sector has to consider the big picture. We have to choose someone who can govern Hong Kong.' A yuan poser Meanwhile, Mr Yam, the HKMA chief executive, will be a busy bee this week. He will lead the Hong Kong Institute of Bankers to Beijing to host the opening ceremony of the institute's office. The market wonders if Mr Yam will meet any mainland officials to talk about the revaluation of the yuan and expand the scope of yuan business conducted by local lenders. card sings to star tunes While many credit cards offer restaurant discounts, free dishes or air miles, BOC Credit Card is singing a different tune, sponsoring 1980s superstar Alan Tam Wing-lun in concert in August. Cardholders can have priority bookings until Friday. 'The response is favourable as the booking hotline is always busy,' a spokesman said. The hot response is no great surprise. After the deaths of Anita Mui Yim-fong and Leslie Cheung Kwok-wing, Mr Tam has become the only Hong Kong superstar from the 1980s still on stage. The latest BOC Credit Card offer follows sponsorship of shows by Sam Hui, Kelly Chen, Sally Yeh, Jenny Tseng and Ms Mui's last concert before she died.
