It appears that HSBC has raised their interest rates to 4.8%. This currently isn't reflected in the advertisements on the main pages of the site, but has been updated on their
rate page and has been confirmed by several people. The new rate is good through the end of April.
ING recently introduced.
Either way, since HSBC is currently
offering a $25 sign up bonus through February 15 with only a $1 deposit, it may be worthwhile to open an account for your emergency fund savings.
