The mid-October military payday is a major pressure point to end the shutdown. However, if Congress passes a narrow bill just to pay service members, it removes the most urgent catalyst for a broader resolution, potentially extending the shutdown for all other government functions.
A prolonged shutdown leaves the data-dependent Federal Reserve "flying blind." This uncertainty, combined with the shutdown's negative economic impact, creates a downside risk that reinforces the case for monetary easing. The lack of new data makes it easier to continue the current cutting cycle.
A shutdown doesn't just delay data reports; if it extends into mid-month, it prevents the government from conducting the surveys needed for future reports. This disrupts the entire data collection pipeline, causing a ripple effect that can obscure economic trends for months after the government reopens.
The direct GDP impact from furloughed federal workers is small, mechanical, and quickly reversed. The more significant and lasting economic damage from a prolonged shutdown stems from its effect on the private sector, such as backlogged IPOs at the SEC or delayed construction projects waiting on permits.
