This document proposes a "Checking Savings Program" to help increase the personal savings rate in the US. It would automatically transfer a percentage of deposits from checking accounts into linked savings accounts, with the transfer percentage gradually increasing over time from 2% to 10% over two years. This would leverage defaults and automatic enrollment to overcome behavioral biases that contribute to undersaving, like loss aversion and procrastination. Rewards would incentivize participation and penalties would discourage early withdrawals. By making saving the default option and easing people into it gradually, this program aims to significantly boost personal savings without requiring changes to individual saving habits.
