Broad-based US Dollar selling marked Wednesday’s Asian session after reports confirmed Democratic control of Congress, including the more closely contested Senate. The result represented a sweeping rejection of President Donald Trump’s policies.

Why are fears of tighter AI regulation unsettling investors?

A rush into the safety of US Government bonds has lowered yields and the US Dollar, while lifting traditional safe-haven currencies such as the Japanese Yen and the Swiss Franc. Behind the shift are market expectations that Democrats will introduce AI-sector regulation and curb data centre construction.

Strong US fundamentals nevertheless continue to underpin the US Dollar in the broader picture and are likely to cushion further declines. Attention later in the day turns to the US ADP Employment Change Report, with employment growth expected to have slowed moderately in October. Meanwhile, the ISM Services Purchasing Managers’ Index (PMI) is expected to register a reading consistent with robust business activity.

Uncertainty over the Middle East conflict is also keeping Brent Oil well above $100, despite continued efforts to restart negotiations. Hours before the elections, the US struck Iranian targets, and Trump has left open the possibility of additional strikes. Fears of an all-out war would likely drive Oil prices higher and re-establish the US Dollar’s safe-haven status.

US midterm elections: key questions answered

What do voters elect in the US midterms?

Held midway through a president’s four-year term, the US midterms are federal elections in which voters elect all 435 House of Representatives members and roughly one-third of the Senate. In many states, voters also select governors and other state and local officials.

On what date will the 2026 midterm elections take place?

Tuesday, 3 November 2026, is Election Day, in line with the federal law requiring it to fall on the Tuesday following November’s first Monday. Many states already have early and postal voting under way.

What is at stake in the US midterm elections?

Control of both chambers of Congress during the final two years of President Donald Trump’s term is determined by the midterms. Setting the legislative agenda and selecting committee leaders fall to the majority party. In the Senate, that party also controls confirmations of judges and senior officials.

Will voters choose a president in the 2026 midterm elections?

No. Presidential elections take place every four years, with the next scheduled for November 2028. Often regarded as a referendum on the incumbent president’s party, midterms have historically tended to cost that party seats in the House.

What could the 2026 midterm results mean for the US dollar?

A limited, temporary response in the US Dollar, rather than a sustained trend, is what most analysts anticipate. The widely expected outcome of a divided Congress is already partly reflected in prices, although Treasury yields could respond more sharply to the results. Expectations of fiscal stimulus generally push both yields and the US Dollar up; conversely, a legislative impasse that restrains fresh spending can weigh on both. Disputes over funding or the debt ceiling may briefly support the Dollar through safe-haven demand. Across a six-to-twelve-month horizon, economic growth and Federal Reserve policy carry more weight than the election outcome.

What is the historical stock-market pattern around midterms?

Weakness ahead of midterms and strength afterwards have characterised US stocks historically. Looking back to 1950, the S&P 500 has recorded gains 12 months after every midterm election: 19 out of 19, averaging about 15%. Analysts attribute this pattern to the reduction in uncertainty after results become clear. Past performance does not guarantee future returns, and some strategists caution that elevated valuations in 2026 could challenge this run.

Why might markets favour a divided Congress?

A divided government has frequently found favour with markets, as legislative gridlock reduces the prospect of far-reaching changes in taxation, spending and regulation. With a Republican president in office, the S&P 500 has historically performed well in the years after midterms that divide control of Congress. Funding deadlines, debt-ceiling disputes and congressional investigations nevertheless pose risks that can increase short-term volatility.
