they want to relocate you from US to HK and don't pay your relocation???
No way!!
they should at least pay the following:
your flight, 1 or 2 flights back to US/year, moving your personal items
anything more (like moving your furniture) is optional (I would not recommend moving your furniture anyway)
other banks don't usually pay relocation packages, only in exceptional cases when you have REALLY HOT skills (no, I don't know what these skills are in banks currently, pls contact the recruitment agencies for that)
but honestly I would worry more about your boss than about your relocation. if she even can't comprehend the necessity of a relocation package when moving you around the world, this smells like more trouble further down the road (e.g. when the first problems arise e.g. with cultural differences and when not everything is going as smoothly as in your business plan). has she managed someone 16 hours away? If not, be prepared for lots of phone calls during the night.
just my 2 cents.
good luck!
