HK sees strong growth in booked wealth still, what is written here with CAGR of 9% which is 3x the one of Switzerland. It has also been confirmed by personal opinions of people working in the industries in said countries. Singapore is the fastest growing if I recall it correctly.
Personally I do bank (transactional and stock trading) in HK but I somewhat feel uneasy about it due to the never ending flow of bad news in the western media, although everything runs as smooth as︀ one would like.
Hong Kong seems much better in practice than perceived due to the︁ horrible news.
