Yes according to CSO after I presented similar situation of May month end balance $1000 and I transferred $50k on 1st week June.
I also asked her what happen if the balance is below $1000 on 2nd week June and $51k end June, would I still get the Bonus interest? The answer is yes.
Note that Bonus interest for above will be for month of June deposit and paid in July.
However, knowing the varying standard of CSO and for the interest of all of us, it would be great if someone is kind enough to also call to re-confirm and post the update here
