The document discusses hybrid financial products that could help address Americans' short-term financial insecurity and long-term savings needs. It notes that about 1/3 of US households struggle with income and expense volatility month-to-month and 60% experience a financial shock annually. Yet 44% do not have $400 for emergencies. It proposes hybrid products that combine features of short-term and long-term financial products, such as combining spending and savings in one account, to help people better manage their finances and meet both current and future needs. Sidecar savings is presented as one example where formalizing accidental short-term withdrawals from long-term savings could help reduce losses and increase affordable liquid savings options.
