Wall Street rallied sharply on Wednesday after Democrats swept both chambers of Congress in the midterm elections, easing political uncertainty and lifting investor sentiment. The Dow Jones Industrial Average jumped 1,569 points, or 3 percent, to 53,356, while the S&P 500 gained 1.6 percent for its best day in three months and the Nasdaq composite climbed 1.4 percent.
The rally was broad, but it had a clear trigger: the prospect that a Democratic Congress will constrain President Donald Trump's agenda, and in particular that it will press for an end to the eight-month-old war with Iran that has driven up energy prices.
What drove the rally
Investors read the result as clarity. With the election over, one large source of uncertainty was removed, and traders bet that divided government would limit new spending and debt issuance — a view that helped send Treasury prices higher and yields lower. Senate Democratic Leader Chuck Schumer has said his party will use its new control over government funding to force an end to the Middle East war, a pledge that fed directly into energy markets.
Brent crude oil tumbled 8.7 percent to $94.62 a barrel on Wednesday, its lowest in more than two months, as traders judged a new US strike on Iran less likely. Cheaper oil, in turn, eased worries about inflation and about further interest-rate rises from the Federal Reserve — a combination that lifted both stocks and bonds.
Winners and losers
Hospital owners and dollar stores serving lower-income Americans helped lead the rally, with Dollar Tree rising 9.6 percent, as investors bet that Democratic control would shift policy toward household budgets. Solar and renewable-energy stocks also jumped on expectations of stronger support for clean energy.
Not everything rose. Data-centre companies and their suppliers fell, in the United States and across Asia on Thursday, as investors priced in tougher regulation of artificial-intelligence infrastructure after Democratic candidates who campaigned on data-centre moratoriums won in Texas and Georgia. Chip stocks were also under pressure in Asian trading.
Bonds, the dollar and oil
In the bond market, the yield on the benchmark 10-year Treasury note fell to 4.88 percent from 4.95 percent late on Tuesday, and extended its decline in Asia. The dollar recorded its steepest single-day fall in two months, dropping to a one-month low against the euro. Gold, which benefits from a weaker dollar and lower yields, held around $4,070 an ounce after jumping 3.3 percent in the previous session.
Oil steadied in Asia on Thursday at around $93.50 a barrel, testing the overnight lows, as traders continued to bet that a weakened president facing a Democratic Congress would be less likely to escalate the war with Iran.
Asia follows, with a rotation
Asian stocks were mixed on Thursday: consumer and financial shares rose following the US gains, while semiconductor shares fell as investors rotated out of chips. The pattern matched the overnight US session — money moving toward sectors seen as winners under divided government and away from the AI-infrastructure trade that had powered much of the year's rally.
Analysts cautioned, however, that the new Congress does not take office until January, so US policy has not actually changed yet. The rally is, for now, a bet on what divided government will mean — not a change that has already happened.
Why history favours post-midterm markets
There is precedent for the optimism. According to Truist Advisory Services, stocks have risen in the year after every midterm election since 1946, including all four occasions when both the House and Senate flipped to the party opposing the president. Whether that pattern holds this time will depend on two things the market cannot yet price: whether the Iran war actually ends, and whether the new Congress and the White House find any common ground at all.
