Global Markets Surge as Democrats Take Congress: Wall Street Jumps and Oil Falls 9% After US Midterms

NEW YORK — Global stock markets rallied on Wednesday, November 4, 2026, after the Democratic Party seized control of both chambers of the United States Congress in the previous day's midterm elections, giving investors the political clarity they had been waiting for — while oil prices plunged nearly 9% as traders weighed what the result could mean for the US-Israeli war with Iran.

What Happened

According to Reuters, all three main Wall Street indices rose sharply on Wednesday. The Dow Jones industrial average gained 2.05%, the S&P 500 rose 1.72% and the Nasdaq Composite climbed 2.46%, with communication services, consumer discretionary and technology stocks leading the advance. Energy shares were the day's biggest losers as crude prices tumbled.

The rally was global. The pan-European STOXX 600 index ended 1.82% higher at 657.40 points, its highest level since August 26 and its steepest one-day gain since June 12, Reuters reported. Spain's lender-focused benchmark climbed 3%, the most among regional bourses. In London, the blue-chip FTSE 100 rose 1.79% to 10,829.21 points, its biggest one-day percentage gain since early May, while the midcap FTSE 250 climbed 0.98% to a two-month high.

In Asia, the picture was mixed at first but ended broadly positive: MSCI's broadest index of Asia-Pacific shares outside Japan rose 0.33%, Reuters reported, after AI stocks that had initially led a decline finished higher overnight. The Associated Press reported that Japan's Nikkei 225 dipped 1.4% to 62,188.63 in early trading, while the Shanghai Composite gained 2.2% to 3,686.17, rebounding from its year-low the previous day. In early European trading, France's CAC 40 rose 0.4% to 8,055.02 and Germany's DAX climbed 0.5% to 25,995.13.

The bond market rallied too. The yield on the benchmark US 10-year Treasury note ended down 0.44 basis points at 4.95%, having fallen as much as 6 basis points to a low of 4.89% overnight, Reuters reported. The weaker dollar left the euro up 0.40% at $1.1234 and the pound up 0.41% at $1.3469, while the Japanese yen edged 0.07% higher to 158.61 and the Swiss franc gained 0.35% against the dollar to 0.818 francs.

Oil was the day's dramatic exception. Brent futures dropped $9.27, or 8.9%, to $94.29 a barrel, touching the lowest level since September 4, while US West Texas Intermediate crude futures fell $7.44, or 7.8%, to $88.54, Reuters reported. In cryptocurrencies, bitcoin gained 3.49% to $80,553 and Ethereum rose 6.2% to $2,434.83.

"Markets hate uncertainty and even though a lot of what the result was had been priced in ahead of time, getting confirmation of that last night brings certainty to markets," Clayton Allison, portfolio manager at Prime Capital Financial, told Reuters. "Now this brings questions as to what actually gets done in Washington over the next two years. But the markets love to see that there is a resolution to a catalyst event."

Background

The scale of the Democratic victory caught some investors off guard. Reuters reported that Democrats scored sweeping victories in Republican strongholds for the first time in generations, with gains in districts long considered safely conservative. In a major setback to President Donald Trump, the party took both the Senate and the House of Representatives in the November 3 vote.

Trump himself acknowledged that the war with Iran had played a role in his party's sweeping defeat, Reuters reported. The United States, alongside Israel, attacked Iran on February 28, 2026, and the conflict has since driven up energy prices, disrupted shipping and shaken global markets — pressures that voters repeatedly cited in exit polls.

That backdrop helps explain Wednesday's split between stocks and oil. For months, uncertainty over the election outcome — and over whether Washington would escalate, wind down or seek a negotiated end to the Iran war — had weighed on markets. A decisive result removed one layer of that uncertainty, even as it opened a new question: what a Democratic Congress will actually do with its majorities when it takes its seats in January.

One early signal came from the technology sector. Opinion polls have shown Democratic voters favouring more control over artificial intelligence, Reuters reported, and investors expect the Democratic-controlled Congress to apply more scrutiny to the sector. The AI boom, driven by heavy spending from tech giants racing to build data centres and expand computing capacity, has propelled global markets in recent years — which has made investors acutely sensitive to anything that could slow the technology's rapid expansion.

There was some reassurance on that front during the session: Advanced Micro Devices rose 1% in early trading after the US chipmaker forecast faster growth through 2027, reassuring investors that demand for AI infrastructure remains strong, Reuters reported.

Treasuries, meanwhile, rallied as investors bet that political gridlock in Washington would restrain government spending, with AI regulation also possibly slowing growth and reducing the need for interest-rate hikes, according to Reuters.

Why It Matters

The market reaction matters because it shows how much of the year's volatility was driven by political uncertainty rather than by company earnings or economic data alone. Once the election result was confirmed, money moved quickly: into stocks, into government bonds, into cryptocurrencies — and out of oil, where traders are now pricing in the possibility that a Congress controlled by Democrats will press harder for an end to the fighting with Iran.

For households and businesses, the oil move could matter more than the stock rally. Brent crude at $94.29 a barrel, its lowest since September 4, eases one of the main drivers of the cost-of-living pressures that voters blamed for the Republicans' defeat — fuel and energy prices. If the decline holds, it could feed through to petrol prices and transport costs in the weeks ahead, although analysts caution that a single day's move in a volatile market is not yet a trend.

For the technology sector, the result cuts both ways. The same AI boom that lifted markets now faces a Congress expected to scrutinise it more closely, from regulation of powerful models to questions about the vast spending on data centres. Shares rose on Wednesday on relief that the election was over, but the policy debate that follows could decide whether the rally lasts.

For the dollar, the shift was also significant. A weaker greenback, with the euro at $1.1234 and the pound at $1.3469, eases pressure on borrowers and importers outside the United States, while making American exports more competitive. Currency strategists noted that the pound's rise also came ahead of the Bank of England's interest-rate decision due on Thursday.

And for the Trump administration, the market verdict is a political fact in its own right. A president who has closely tracked stock market performance now faces two years of a Congress controlled by the opposition — with power over spending, nominations and war authorisation — while markets cheer the very gridlock that limits his agenda.

What Happens Next

Traders now turn to a busy run of catalysts. The Bank of England announces its interest-rate decision on Thursday, November 5, and the United States releases its nonfarm payrolls report on Friday — both will test whether the post-election rally has a fundamental footing or was mainly relief at a resolved election.

On the geopolitical front, attention stays on Washington's next move in the US-Israeli war with Iran, which drove Wednesday's violent swing in oil. Trilateral talks involving Russia, Ukraine and the United States are set for Abu Dhabi on November 10–11, according to market commentary, adding another diplomatic date to watch.

In January, the new Democratic Congress takes its seats and begins to exercise its powers — on Iran authorisation, on spending, on nominations and on scrutiny of the administration's foreign policy. How far Democrats go, and whether Trump responds with vetoes or with new executive action, will shape markets through 2027 far more than a single day's rally.

For now, Wednesday's message from markets is clear: certainty, even the certainty of gridlock, was worth buying — and oil traders are betting that the election result brings the end of the Iran war a step closer.
