Resiliencia del mercado durante las interrupciones gubernamentales: cómo las intercambios de EE. UU. mantienen el comercio en pie

Government shutdowns in the United States have historically been treated as non-events by financial markets. Despite the political drama and uncertainty, major exchanges like the New York Stock Exchange (NYSE) and NASDAQ have consistently maintained operational continuity, ensuring that trading proceeds without disruption. This resilience is not accidental-it's a result of well-established protocols, regulatory frameworks, and the inherent adaptability of market infrastructure. Let's break down how these exchanges navigate shutdowns and what investors should know.

Historical Precedents: Markets Rise, Politics Fall

The 2013 and 2018-2019 government shutdowns offer clear evidence of market resilience. During the 2013 shutdown, the S&P 500 advanced 3.1% despite the political chaos. Similarly, in the 2018-2019 shutdown, the index rose 10% over 35 days. These trends repeated in October 2025, when the S&P 500 hit a record high of 6,711.20 points on the first day of the latest shutdown. Investors, it seems, treat shutdowns as background noise rather than existential threats.

This pattern underscores a critical truth: financial markets are forward-looking. While government dysfunction may delay economic data releases (e.g., jobs reports, inflation figures), according to analysis, the core function of exchanges-facilitating capital formation and liquidity-remains intact.

Operational Continuity: Exchanges vs. the SEC

The NYSE and NASDAQ are private entities, not federal agencies, which means they aren't directly impacted by shutdowns. However, their operations are indirectly influenced by the Securities and Exchange Commission (SEC), which operates with a drastically reduced workforce during such periods. According to recent contingency plans, the SEC would retain only 9% of its staff to handle "essential functions" like accepting filings via EDGAR. Crucially, it would not review filings, declare registration statements effective, or provide interpretive guidance.

This creates a unique dynamic: exchanges continue to operate, but companies relying on SEC approvals face delays. For example, initial public offerings (IPOs) or mergers requiring regulatory clearance may stall. Yet, as the 2025 shutdown demonstrated, trading itself remains unaffected.

NASDAQ's Contingency Playbook: Flexibility in Action

NASDAQ has been particularly proactive in outlining contingency measures. During the 2025 shutdown, it clarified that companies which had resolved all SEC comments prior to the shutdown would still be listed, even if their registration statements became effective during the shutdown.

For firms with unresolved SEC comments, NASDAQ adopted a case-by-case approach, prioritizing those that had "substantially completed" the comment process and demonstrated clear resolutions to outstanding issues.

This flexibility highlights NASDAQ's role as a market infrastructure provider. While it cannot bypass the SEC's regulatory authority, it has found ways to maintain liquidity and investor confidence by focusing on pre-shutdown compliance. Notably, NASDAQ also provided distinct guidance for over-the-counter (OTC) companies transitioning to its exchange, emphasizing the importance of 1934 Act registration statements.

Investor Takeaways: Adapt and Communicate

For investors, the key takeaway is that government shutdowns rarely disrupt market fundamentals. However, companies must prepare for operational friction. Public companies are advised to:
1. Maintain transparent communication with stakeholders about potential supply chain or financial impacts.
2. Accelerate pre-shutdown compliance for capital-raising activities to avoid delays.
3. Develop contingency plans for scenarios where regulatory approvals are delayed.

Investors should also monitor how companies navigate these challenges. Firms with robust contingency planning and strong regulatory relationships are likely to outperform during shutdowns.

Conclusion: Resilience as a Feature, Not a Bug

The U.S. financial system's resilience during government shutdowns is a testament to its design. While the SEC's limited operations create friction, the NYSE and NASDAQ's ability to adapt ensures that markets remain functional. For investors, this means treating shutdowns as temporary hiccups rather than systemic risks. As history shows, markets don't just survive-they thrive.
