How is Endowus Cash Smart Enhanced different from Singlife? Both have a target return of around 2% per annum right?

Singlife gives guaranteed 2% while endowus one might fluctuate (some small risk invovled)

Endowus Cash Enhanced is a cash management product, where they will invest your funds and aim for a projected return of up to 2% PA. Think of it like a fixed deposit with no lock-ins. Believe it takes 5-6 business days if you want to withdraw.

Singlife is an insurance savings plan, with no lock-ins too. Good thing here is you can withdraw your money any time almost instantly. Would really depend how long you need access to these moneies. If it's several months or years, park it in Endowus. If you need instant access, go for Singlife. Personally, I park my emergency funds with Singlife, knowing that I can withdraw them anytime if I need spare cash.
