"$5 billion is a possibility, but it could be more or less than that," he told CNNMoney.com. "The numbers will depend on the timing of the budget and the state's cash flow situation at the time of signing."
California has been without a budget since July 1, as state lawmakers grapple with a $19.1 billion shortfall. The impasse has resulted in state workers being furloughed and raised the possibility that the state would have to issue I.O.U.s to creditors.
The bank loans would be in lieu of money the state normally raises by selling short-term "revenue anticipation notes" to investors. But California cannot issue such debt due to disclosure requirements that it cannot fulfill without a budget.
Once the budget is passed, the state would issue notes within weeks to repay the bank loans, according to DeAnda. After a drawn-out budget stalemate in 2009, he said, California borrowed $1.5 billion which was repaid one month later.
Gov. Arnold Schwarzenegger said last week that state officials have reached "a framework of an agreement" on how to close the deficit.
