The banking system has problems. This book proposes a banking system with fewer problems. This is done by considering criteria that might be associated with a sound currency. Various classifications of banks are discovered, and perpetuals are used as a case-study. A final design is proposed: unified residualized banking that balances hedged currency with representative currency. It uses leverage to increase competition and resilience, opening up an information channel that encourages optimal capital deployment. Rough design decisions are suggested, with the specifics left as further research.
