That is not true at all. You are probably thinking of the minimum capital requirements (banks leverage) which measures all lending (bank assets) against their common equity. Deposits and credits are roughly equal and the minimum capital is required to cover mispricing on their assets. And no, banks are not being deregulated in this regard. In fact Basel III which regulates those reserve ratios is much stricter and it took several years for banks to recapitalize to the new minimum levels.

Or you are thinking about the bank's deposit with the fed (the fractional reserve part). But those reserves are not a problem for banks because if there is lack of reserves on the interbank market and the price (interest rate) of borrowing reserve increases above the fed's funds rate, then the Fed steps in and provides the reserves at the rate it wants to keep. This is part of central banking because a central bank cannot simultaneously control the amount of reserves AND the interest rate.
