I have around 50k emergency funds and are currently putting them in Singlife and Singtel dash. But they are reducing the rates and it’s not attractive anymore. Is there any low risk alternatives?

Perhaps consider cash management accounts such as Endowus Cash Smart. They have varying risk levels, although of course all are low risk, it's more of which is the lowest risk haha. The (projected) returns range from 0.8% to 2.0%. Note however that as opposed to plans like Singtel Dash and Singlife, your principal is not guaranteed. Although that said, it is also very very unlikely that you will lose your capital in these cash management accounts.

Also, pardon me for asking but can I also enquire as to why are you holding 50k in emergency funds? Does this include your savings for large purchases as well? Most people would advocate about 6 months of expenses for savings or in a more conservative fashion, 9-12 months. If 50k is your 6-12 months of expenses then my apologies go ahead. But if it is much more than that, then perhaps considering putting some of it to work in higher risk investments for a longer term investment.​​​
