I am a customer of Bank of America. Whenever I go online and transfer money from my checking account to pay back money I borrowed from the checking account 's credit line, the money is debited immediately from my checking account. However it takes from one to three days for the money to be credited to my credit line. The bank 's customer service reps tell me the delay is caused by " processing. '' What kind of processing could there be? It 's all money under XXXX name in XXXX bank. All the transfers are done on computers. I was also told that transferring money from checking to savings does not require " processing. '' The money is credited immediately to the savings account. I was also told that this is bank policy ; they are not following any government regulations in handling my money. I suspect that the delay in crediting me is a money-making device for the bank. By removing money from my checking account immediately, the bank can reduce the interest it pays me for funds in my checking account. The bank also has use of my money and I do n't. But the third feature is the most significant. By delaying the crediting of my credit line, the bank can continue to charge me 18 percent for the borrowed funds. If you multiply the money the bank makes on this kind of transaction by all the customers who use their credit lines, you are looking at a huge sum. Please look into this for me.
