The bank is in the UK. I don't know if there's any legislation around this communication, but it doesn't seem that great even if it's legal.

You're worried about unfair competition with banks advertising "0.1%" or "0.2%", but with a must rule like this, there wouldn't be any of those competitors. Anyone with the same rate would advertise "0.10%", and anyone who wanted to beat would say "0.20%" (or more likely, "0.11%").

Probably - iirc FSA regulate that stuff and can be quite pernickety about what they'll allow.
