Where should I look to deposit my savings now that Singlife/ Singtel dash are not accepting new customers?

1-2% really just put in bank. Unless you are saying like 6figures then again also all the savings account have a limit.

I personally use Endowus and Syfe's cash management accounts. The interest rate is about 1.4 - 1.7% per annum. It is generally low risk as it invests in short-term bonds which means a lower chance of defaults.
