After the vote: what markets may watch next

The election decides who controls Congress. The result could change expectations for US spending and trade policy, with several developments worth watching in the weeks ahead.

Close races. If control of either chamber remains undecided, uncertainty could extend beyond election night.
Fed policy. The Fed's December meeting and updated economic projections could shift interest rate expectations, affecting the dollar and Treasury yields.
Government funding. A dispute over the December funding deadline could weigh on market sentiment, while an agreement may ease uncertainty.
Trade and China. The White House retains considerable control over tariffs and export restrictions, although Congress can influence policy through legislation and oversight.
The new Congress. From January 2027, the balance of power could shape negotiations over government spending and the debt ceiling.

Bear in mind that other factors, such as inflation, interest rates and economic growth, will also continue to influence markets.

FAQ

What is the purpose of midterm elections?

Midterm elections determine which party controls each chamber of Congress. Congress passes laws, approves federal spending and oversees the executive branch. The results can indicate public support for the sitting president and affect their ability to pass legislation. However, the president retains their veto and executive powers regardless of the outcome.

Which states have midterm elections in 2026?

All 50 states hold House elections in 2026, with every seat up for election. There are also 35 Senate races – 33 regular contests and special elections in Florida and Ohio. Thirty-six states will elect a governor.

How do elections affect the stock market?

Elections can influence share prices by changing expectations for government spending, taxation, regulation and trade policy. Depending on the outcome, some sectors may benefit while others face greater uncertainty or costs. However, wider factors such as interest rates, inflation, company earnings and economic growth also affect market performance. Share prices can rise or fall before and after an election, and past performance is not a reliable indicator of future results.
