As I expected, StandChart eSaver is having the top-up interest rate offer again, this time at 1.5%. Coincidentally, OCBC FairPricePlus slashed its rate from 1% to 0.5% starting March.

Also as I expected, the 2% interest rate is a gimmick, which only applies to the top-up amount until April. Subsequently the rate drops back to 0.4%, while the contract to wire $1K per month for 6 months remains. I suppose it was closing time soon so the banker was rather straight to the point without me probing further.
