In the aftermath of the Panic of 1907, there was general agreement among leaders in both parties of the necessity to create some sort of central banking system to provide coordination during financial emergencies. Most leaders also sought currency reform, as they believed that the roughly $3.8 billion in coins and banknotes did not provide an adequate money supply during financial panics. Under conservative Republican Senator Nelson Aldrich's leadership, the National Monetary Commission had put forward a plan to establish a central banking system that would issue currency and provide oversight and loans to the nation's banks. However, many progressives distrusted the plan due to the degree of influence bankers would have over the central banking system. Relying heavily on the advice of Louis Brandeis, Wilson sought a middle ground between progressives such as William Jennings Bryan and conservative Republicans like Aldrich. He declared that the banking system must be "public not private, must be vested in the government itself so that the banks must be the instruments, not the masters, of business."
