In "America's Bank: The Epic Struggle to Create the Federal Reserve," author Roger Lowenstein discusses the efforts of various bankers who succeeded the Indianapolis convention. These bankers continued to advocate for financial reform, though their approach differed from that of Warburg. They supported the idea of an asset currency, which emphasized a decentralized model reliant on the loans made by individual banks. This concept of asset currency represented a significant shift from centralized control, as it aimed to link the currency directly to the financial activities of individual banks. The proposal reflected the ongoing debate about how to structure the banking system in a way that would enhance stability while promoting financial autonomy among banks.
