Hi there, if you've maxed out the first 2% already, perhaps close alternatives to consider would be Singtel Dash EasyEarn or Etiqa's GIGANTIQ.
Both offer you a guaranteed 1.8% p.a. for the first year. They are both SDIC protected too. The main difference is for Dash EasyEarn, the min. deposit is $2,000 and the account limit for the promotional 1.8% rate is $20,000.
For GIGANTIQ, the min. deposit is $50, but the account limit is only $10,000.
I reviewed both of them here. Personally, I'll choose to max out Dash EasyEarn first then move the rest of my funds to GIGANTIQ. Anyway there are no lock-ups for both, so if the rates aren't good next year, you can just move your money somewhere better!
