No they don't, banks have accounts with the central bank. They also have their assets and liabilities. They have to manage the system so that they can manage external withdrawals. When assets outweigh liabilities it's a bankruptcy. When current demand for withdrawals exceeds short term liquid reserves it's a liquidity issue. At no point do banks create base money. A balance in a bank is just an iou for base (central bank's) money.
The only entity that creates money is the central bank. They may even accept mortgages from banks as collateral (including repurchase agreements) to inject new money into the system.
Regulations are supposed to prevent bankruptcy and liquidity issues, but even without any regulations regarding asset ratios, banks can go bankrupt or illiquid.
