it differs a lot.
Mevas Bank a bit higher than average, about 4% depending on how much $.
My Standard Chartered account (Disney) with my girl's name on it has 3.65%, savings account only over $150,000, till end of March.
Citigold last month time deposit 3.9% for a month+ $2000 credit card free spending for new account, but minimum $1M.
Better ask Mevas first as Mevas normally gets the best rates.
