IMO, Everbank is for suckers. The spreads and CD rates are very unattractive relative to a forex account via Saxo or Interactive (if you can accept the latter's very user unfriendly platform). I think the only thing Everbank offers that can't be duplicated with the above mentioned brokers is RMB exposure. But Everbank"s RMB account pays no interest and has a nasty bid/ask spread. The bank is Florida based and has terrible service too.
The better way to invest in RMB is to go to a bank in China, open an account, and wire the money over (up to $50,000 direct per year but there are easy ways around this limitation if you want more exposure), and convert it to RMB. Once you have your RMB account, you can buy fixed rate CDs (1.9 - 4.2% annual interest depending on term) and your bid/ask spread will be very attractive. Also, the smallest of the 5 government banks also offers a low risk product which pays up to 6-8% with capital protection and minimum annualized rate of 1.2% guaranteed for each quarter. Since inception some 16 months ago, it has averaged about 5% with 3.6% on its wost month.
