Conference is definitely going ahead. Meanwhile they aren't yet fully sure they are scrapping hotel quarantine after this cycle. So this is a fallback.
I still think they will get to no more hotel quarantine for vaxed residents from Nov... but probably to a home arrangement, and many of these bank chiefs aren't residents, and might not even be vaxed. You can hardly declare Hong Kong open and stay totally closed at the same time so there will have to be some progress. There are also plenty bank execs uneasy with the optics of coming in on exemptions, so the gap will need to be narrowed.
