A grey and red stepped line chart showing a projection of the U.S. Treasury balance between May 30 and June 30, 2023. Positive numbers are in grey, and negative in red. This shows a worst case scenario where the balance goes negative on June 1. In this scenario, the balance will remain below 0 until quarterly tax revenues arrive on June 15. It bounces between positive and negative for a week before crashing to more than -$90 billion when Medicare payments go out on June 30.
