Former central banker Joseph Yam Chi-kwong, who 29 years ago helped create the Hong Kong-US dollar peg, yesterday triggered wild debate by saying the city could 'do away with the exchange rate target' to curb inflation and asset bubbles.
Yam, now a Chinese University professor, repeatedly stressed he was not proposing an immediate removal of the peg, set at HK$7.8 to US$1 and introduced on October 17, 1983.
But the research paper he released yesterday immediately caught public attention.
At a press briefing, he said Hong Kong needed 'a continuous and vigorous intellectual exercise to consider whether the monetary system is serving the public interest'.
Yam wrote: 'There is no doubt the [peg] has, for almost 30 years of its existence, been a pillar of stability for Hong Kong, but there are costs involved.
'As with all jurisdictions operating with a fixed exchange rate, it is not possible for adjustments to economic shocks of all descriptions to work through the exchange rate.
