Which savings bank to park 50k and let it grow without touching it and monthly putting in about 7k? but still able to withdraw in case of emergencies?

You can use GXS bank to earn a 3.48% Interest rate for maximum of 5K when you save in the pocket feature . There is a promotion of earning extra $2.50 when you earn $2.5 in interest. Up to $10

So many .. if you willing to work for it, highest in the market is RHB HYSA/PP and HSBC EGA currently but need a bit homework, however, SIF Gosaver, CIMB Fastsaver and GXS Bank you may check if you prefer easier and fuss free accounts
