How likely is Singlife able to maintain the 2.5% in the near future?

Let's be honest.

Nobody knows.

This is a feature in their current marketing plan. Simply put, about $250 per new customer acquisition for deposits of up to $10k and 2.5% interest.

Once they analyze the result, they may stop it or even make it a permanent feature, nobody knows.

Depending on the health of the company.

But a damn good marketing campaign I would say :)

I think so far, they have been able to hit it quite consistently! I've managed to even rack up a decent interest rate from them!
