Quote from dhpar:
i too switched all my USD into HKD about 1 month ago after the US short rates were decided to stay low for ever. given the minimal negative carry I pay I am willing to wait for years for HKD to appreciate from the 7.75/7.85 band.
but as asia/china is in a secular uptrend it makes sense for HK to float HKD early. there is no reason to hold USD in medium/long term - the currency must weaken to help fix many of US problems (debt/energy/balances). this is the same thing as to say that asian currencies must appreciate to solve many of their problems (stability/energy/balances).
note that to solve the current HK problems they must de-peg (not re-peg). the basket peg makes no sense whatsoever. in other words you must be given chance to tighten the monetary condition (leave USD peg) while not give people chance to bet on Yuan appreciation (not join RMB peg). as soon as RMB gets convertible I guess HKD will be abolished altogether at some fixed rate to RMB (which is basically the same thing as pegging to Yuan).
when you are in HK you can see Yuan everywhere - it is basically a parallel currency. bid/offer at street exchanges is basically zero - people there would be delighted to switch to Yuan...
