Courtney - My XE account is all set up - only my first transaction is going to be from HSBC USA to NatWest. I checked it all out and registered my HSBC USA account as an EFT account for XE. I called HSBC and they said that there is no fee for outgoing EFTs. So that sounds great! I'll let you know how it works.
Also, regarding credit record transfer...HSBC USA can can transfer your credit record for any HSBC credit account (credit cards, loans, mortgages, etc). They cannot/will not transfer credit records for any accounts held with other financial institutions.
