The numeraire could be the Hong Kong dollar, the U.S. dollar
or the average of the snake currencies.
Although the main objection
to a local currency guarantee could be removed by eliminating a
unilateral revaluation from consideration, at present such a guarantee
would be tantamount to a U.S. dollar guarantee to which the Hong Kong
dollar is linked. Furthermore, it is possible that from now on,
