Money pass through bank account and effect to refinancing

[Chris Penny]

I have a bank account, called Bank A, that, for a specific reason, needs to have multiple money pass through. By that I mean I constantly need to move money from another account to this Bank A, then immediately wire the same amount from this Bank A account to another trading account. 

Now if I refinance my home, or buy another one, I understand that the lender would check every bank account and ask for an explanation of any nonregular large deposit. Given that I would have multiple large deposits, but at the same time I wire the amount received immediately to another account, do I have to explain this to the lender?
