2 weeks ago the Treasury General Account (TGA) had drained roughly $200B from its highs and looked to be entering the kind of multi-month drawdown phase that historically pulls hundreds of billions of dollars back into the financial system.
The setup was relatively straightforward at the time: as the Treasury continued to spend down its operating cash, that liquidity would flow back into markets and ease one of the structural headwinds that had been weighing on risk assets through Q1.
The April 15 tax deadline interrupted that drain.
TGA balance for the week ending April 22 printed at $1,006B, putting the balance back at the same level Treasury staff projected three months ago, when they told primary dealers in their February quarterly refunding statement to expect a late-April peak around $1,025B (plus or minus $50B), with declines starting in May.
In other words, the cycle itself has not changed only the timing has shifted by a couple of weeks. The April 22 reading sits at the level Treasury itself identified as the cycle peak rather than a steady-state operating level, which means the seasonal drainage scheduled into May and June still has to happen.
Where The Cycle Stands
The weekly TGA balance peaked at $958B for the week ending October 29, 2025, with daily readings briefly running above $1.05T into early November as Treasury accumulated cash ahead of expected fiscal outflows. From that peak, the account drained steadily through Q1 2026 as Treasury funded obligations without leaning aggressively on new issuance, with the week ending April 8 marking the trough at $748B – a $210B drawdown on the weekly series and closer to $300B on the daily. The April 15 tax deposit then lifted the weekly average back to $1,006B, putting it within a small margin of where the cycle started in October.
What’s worth pointing out is that this cycle is not unusual in any structural sense. Treasury’s quarterly
