Brent Crude Slumps as Democratic US Election Win Boosts Asian Stocks

Asian stocks rallied on Thursday, November 5, 2026, as oil prices plunged following a Democratic sweep in the US midterm elections, raising hopes for a de-escalation in the Iran conflict. The MSCI Asia Pacific Index rose, driven by gains in e-commerce and automobile stocks, while Brent crude fell to $94.10 a barrel, extending a three-day slump of approximately 19 per cent.

Democratic Sweep Fuels Market Optimism

The Democratic party’s midterm electoral victory has significantly boosted market sentiment. US President Donald Trump accepted the election outcome and suggested openness to working with the new Democrat-dominated Congress, which helped dissipate fears of political upheaval. This move, coupled with Senate Minority Leader Chuck Schumer pledging to end the Iran war, has led investors to anticipate faster US-Iran diplomacy and a reduction in the geopolitical risk premium embedded in oil prices.

The stock market is now celebrating congressional gridlock, President Trump’s willingness to work with the new Congress, and the fact that the Trump administration may not immediately attack Iran now that new negotiations are anticipated.

The S&P 500 and Nasdaq Composite rose 1.58 per cent and 1.44 per cent, respectively, overnight, with the Dow Jones Industrial Average gaining 1,570 points, or 3 per cent. This rally continued into Asian markets, with equity-index futures for Japan, Australia, and Hong Kong pointing higher.

Why are stocks rising and oil prices falling after election night's Democratic sweep?

Oil Prices Tumble on Peace Hopes

Oil prices have seen a dramatic decline. Brent crude, the benchmark for two-thirds of the world’s oil, sank over 8 per cent to below US$95 a barrel on November 5, after falling approximately 19 per cent over three days. West Texas Intermediate (WTI) also dropped in price. Oil’s retreat below the $100-per-barrel mark came after Trump acknowledged that the Iran war was a chief reason for his party’s defeat in the polls.

Tech Stocks Face Regulatory Concerns

While broader Asian markets advanced, technology stocks came under pressure due to concerns over AI regulation. The Kospi Index in South Korea, a bellwether for the AI trade in Asia, dropped 4.39 per cent.

The Democratic sweep raises the real possibility that the AI data-centre buildout hits a regulatory brick wall if the party follows through on its pre-election pledges. That has kept semiconductor names under pressure across the region.

Market analysts note a clear rotation away from chipmakers. Despite this, many investors see little immediate threat to the AI investment theme that has powered a rally in stocks tied to the sector.

Selective Gains and Economic Data Ahead

The rally in Asian markets was selective, with significant gains in e-commerce and automobile stocks. Toyota shares surged 8 per cent, while those of Hyundai Motors advanced 3.7 per cent.

Investors are also looking ahead to a series of economic data, including US manufacturing activity and labor-market reports. US job openings data due Tuesday are expected to show listings edged higher in September, while weekly jobless claims Thursday are seen remaining near historically low levels.

It’s going to be an extremely interesting week in the markets. We’ll have political issues to decipher as well as geopolitical ones. And growing doubts about AI investment returns will likely matter much more than historical patterns in determining the market’s direction going forward.

The market's direction will likely hinge on these interconnected factors, with historical patterns taking a backseat to current uncertainties.
