After the midterm elections: How will markets react?

The post-midterm market impact will depend on the size of congressional majorities and the fiscal and regulatory agenda that follows.

• Democrats gained more seats than expected, while the Republican White House retains an executive veto that could constrain major changes to taxes, spending, and regulation.
• Government funding expires on December 11, and a short-term continuing resolution could push the next budget deadline into 2027.
• October 2027 could bring together the start of fiscal year 2028 and the Treasury’s debt ceiling X-date, creating a risk of market stress if shutdown and debt ceiling negotiations overlap.
• The author expects continued high deficits in fiscal years 2027 and 2028 because both parties support more spending and tax increases may remain limited.
• Congressional hearings could target oil and gas companies, Big Tech, social media, AI safety, data centers, utilities, and semiconductor firms.

Takeaway: Investors should focus on fiscal negotiations and congressional oversight after the election, with higher risk premiums possible during recounts, shutdown talks, or debt ceiling negotiations even though a technical default remains unlikely.
