THE size of the territory's foreign reserves will be made public every three months. The change is to increase government openness. Financial Secretary, Donald Tsang Yam-kuen, said: 'The Mexican crisis has raised concerns about the timeliness and consistency of international data, especially data on the balance of payments and external reserves. 'The world today feels that full disclosure and transparency is preferred, and as an international financial centre and a good global citizen, Hong Kong will undertake to provide the world with the full picture of our success story.' At the end of June, the reserves were US$53.6 billion (HK$414 billion). 'We think it's time to remind the world at more frequent intervals of the strength of our financial position,' said the Monetary authority's chief executive, Joseph Yam Chi-kong.
