The next US midterm elections are on 3 November 2026. The results could shape taxes, government spending and business rules, which may affect currencies, stocks and gold. Looking at the 2014, 2018 and 2022 elections can help traders understand what drove prices and what to watch this time. In each case, inflation, interest rates and central-bank decisions also played a big role, so it helps to look beyond the election result.
What are US midterm elections?
Midterms take place halfway through a president’s four-year term, with Americans voting for all 435 House seats, about one-third of the Senate and many state officials. The president stays in office, but control of Congress can change, affecting how easily laws on taxes, spending and other policies can pass.
The president’s party often loses House seats, so this may already be expected. For markets, what matters is how the result compares with expectations and what it means for policy.
Why do traders follow the results?
Democrats are currently expected to win the House, while Republicans may keep a narrow Senate majority. politicalsciencenow.com Traders will watch whether the results match those expectations and what they mean for Trump’s plans. A surprise result or a long wait for close races to be decided could bring bigger market moves.
2014 — Central banks were already moving markets
Republicans won the Senate and increased their House majority in the 4 November election, giving them control of both chambers of Congress. President Barack Obama, a Democrat, would need Republican support to pass major legislation during his final two years in office.
Markets were also following the Fed’s decision to end its bond-buying programme and the Bank of Japan’s announcement of more monetary support. Both decisions came just before the election.
Week before the election:
FX: USD/JPY +5.0%; EUR/USD −1.5%.
Shares: Dow +2.2%; S&P 500 +1.4%; Nasdaq +1.3%; Nikkei +10.0%.
Gold: −4.8%.
One week after:
FX: USD/JPY +1.2%; EUR/USD −1.0%.
Shares: Dow +1.3%; S&P 500 +1.4%; Nasdaq +0.8%; Nikkei +1.6%.
Gold: −1.5%.
One month after:
FX: USD/JPY +5.5%; EUR/USD −1.0%.
Shares: Dow +3.0%; S&P 500 +3.0%; Nasdaq +3.2%; Nikkei +6.1%.
Gold: +3.0%.
What drove the major moves?
Republican control of Congress limited Obama’s ability to pass major spending or tax changes without opposition support. However, the clearer market drivers were the different policies of the Fed and Bank of Japan, which helped lift USD/JPY and Japanese shares before the vote. Gold initially fell alongside dollar strength, then recovered over the following month.
2018 — The first rally did not last
Democrats won the House in the 6 November election, while Republicans kept the Senate. This ended Republican control of both chambers and made it harder for President Donald Trump to pass further legislation without Democratic support.
Markets entered the vote after a sharp October sell-off, with investors concerned about Fed rate hikes and US–China trade tensions.
Week before the election:
FX: USD/JPY +0.5%; EUR/USD +0.4%.
Shares: Dow +3.1%; S&P 500 +2.7%; Nasdaq +3.0%; Nikkei +3.2%.
Gold: +1.2%.
One week after:
FX: USD/JPY +0.5%; EUR/USD −1.1%.
Shares: Dow −1.4%; S&P 500 −1.2%; Nasdaq −2.4%; Nikkei −1.5%.
Gold: −3.0%.
One month after:
FX: USD/JPY −0.8%; EUR/USD −0.3%.
Shares: Dow −2.7%; S&P 500 −2.2%; Nasdaq −2.5%; Nikkei −2.9%.
Gold: +0.1%.
What drove the major moves?
The divided Congress reduced the chances of further Republican tax cuts and major changes to existing laws. Shares rallied immediately after the vote as investors welcomed the broadly expected result and fewer prospects for large policy changes. However, worries about Fed rate hikes and trade tensions remained, and the rally faded.
2022 — Inflation news quickly took over
Republicans won a narrow House majority after the 8 November election, while Democrats kept the Senate. Republican gains were smaller than some had expected, but the result still meant President Joe Biden would face a divided Congress.
Investors were watching how this might affect government spending, while high inflation and the Fed’s rapid rate increases remained major concerns.
Week before the election:
FX: USD/JPY −1.8%; EUR/USD +2.2%.
Shares: Dow +1.6%; S&P 500 −0.7%; Nasdaq −2.5%; Nikkei +0.7%.
Gold: +1.1%.
One week after:
FX: USD/JPY −4.1%; EUR/USD +2.8%.
Shares: Dow +1.3%; S&P 500 +4.3%; Nasdaq +7.0%; Nikkei +0.4%.
Gold: +6.2%.
One month after:
FX: USD/JPY −6.1%; EUR/USD +4.6%.
Shares: Dow +1.9%; S&P 500 +3.5%; Nasdaq +4.4%; Nikkei −1.1%.
Gold: +6.7%.
What drove the major moves?
Republicans winning the House made it harder for Biden to pass further large spending plans, but their narrow majority fell short of the sweeping victory some expected. The result offered no clear market direction. Two days later, lower-than-expected inflation raised hopes of slower Fed rate hikes, pushing yields and the dollar lower and helping US shares and gold rise.
What can traders learn from past midterms?
Politics matters because government decisions affect the economy, businesses and confidence, but each election takes place under different conditions. A win for the same party can bring a different market reaction depending on what investors expect and what else is driving prices.
An expected result may cause little movement, while a surprise could change the outlook for policy. As past midterms have shown, interest rates, inflation, jobs data and central-bank decisions can matter more than the vote itself. Looking at these factors alongside the election helps traders prepare without assuming markets will repeat the past.
