Democrats win Congress, and bonds rallied as AI shares fell. What matters next for money: the 11 December funding deadline, the debt limit and the Fed.
Democrats win Congress. They took the House and the Senate in the midterm elections of 3 November, CBS News projects, and flipped seven Republican Senate seats, where a net gain of four gave them control. Overnight, investors sold the AI shares that have led the market and bought Treasuries: the 10-year yield fell 6bp to 4.906%, Reuters reported. For money, the new Congress matters less for the laws it can pass, which President Donald Trump can veto, than for the bills he needs it to pass: government funding, the debt limit and his nominees.
CBS News projected the House for the Democrats at 10:15pm in Washington on Tuesday and the Senate shortly after 11:30pm. The Senate seats that changed hands run from Maine, where Troy Jackson beat Susan Collins, to Texas, where James Talarico beat Ken Paxton, with North Carolina, South Carolina, Ohio, Iowa and Kansas in between. Alaska, Mississippi and Nebraska were still too close to call early on Wednesday. Democrats also won the governor’s races in Texas, Georgia, Ohio and Iowa. Gina Hinojosa is the first Democrat to win the Texas governorship since Ann Richards.
The new Congress sits from 3 January 2027, the date the 20th Amendment sets. Until then the outgoing Republican majorities hold a lame-duck session. And the sweep has a ceiling: overturning a veto takes two-thirds of both chambers, under Article I of the Constitution, and Democrats are far short of that. “Trump still has veto power - that will be one of the sticking points for the remaining two years,” Tai Hui of J.P. Morgan Asset Management told Reuters.
Bond yields had already fallen in the month before the vote. The 10-year Treasury yield closed election day at 4.95%, Treasury’s daily figures show, down from 5.31% on 5 October, its highest close of September and October. The 2-year was at 4.61%.
The night itself hit technology hardest. Nasdaq futures fell more than 2% at one point before cutting the loss to 0.5%, while S&P 500 futures were down 0.35% and the euro rose 0.5% to $1.1249, Reuters reported early on Wednesday. By 3:23am in New York, S&P 500 and Nasdaq 100 futures had turned higher, CNBC reported, with the chipmaker AMD up 5% after strong results. Traders bet that a Democratic Congress will slow the data-centre buildout, CNBC reported. Texas is one reason: in July Hinojosa called for a moratorium on new data centres until the state’s lawmakers act on power and water costs.
The power bills behind that campaign are real but modest. US electricity prices rose 4.4% in the year to September, against 3.7% for all consumer prices, by our calculation from the Bureau of Labor Statistics’ electricity index and its index of all items. Two strategists told Reuters the AI sell-off began weeks before the vote. Hui asked how much was “really the election, how much is the AI story”.
The government is funded by a stopgap law, H.R. 6500, which the White House says keeps agencies running “through December 11, 2026”. That deadline falls in the lame duck. The outgoing Republican Congress must pass the next bill, and in the Senate most bills need 60 votes to end debate, so Democratic votes as well.
The election changes Democrats’ incentives. A short extension into January would let the new majorities write the full-year spending bills themselves. A full-year deal before Christmas would settle spending until next autumn on terms struck before the new majorities arrive. Either way, a shutdown is a real risk in December.
The bigger fight comes next year. On 2 November the federal debt subject to the limit was $40.31tn, against a statutory limit of $41.10tn, Treasury’s Daily Treasury Statement shows. That leaves $797.7bn of room.
Total public debt rose by $2.53tn in fiscal 2026, from $37.64tn to $40.17tn, Treasury’s Debt to the Penny shows. At that pace, the room lasts about four months, into early 2027, by our calculation. After that, Treasury can shift money between accounts for some months more before it runs out of ways to pay every bill. “You do have a debt ceiling some time next year,” Hui told Reuters.
So the first debt-limit standoff lands on a Democratic Congress, with a Republican president who needs its votes. It comes as borrowing costs bite: net interest on the debt cost $1.05tn in fiscal 2026, the Monthly Treasury Statement for September shows.
On tariffs, the Supreme Court has already done what a Democratic Congress could not. In February it ruled that the emergency-powers law Trump used does not allow him to impose tariffs. The administration replaced them: since July, tariffs of 10% or 12.5% apply to imports from 60 economies, the Trade Representative’s office says, under Section 301 of the Trade Act of 1974. Those rest on laws Congress passed long ago. Ending them would take a new law, and Trump can veto it.
The revenue shows how much is at stake. Customs duties raised $173.2bn in fiscal 2026, down from $194.9bn in fiscal 2025 but more than twice the $77.0bn of fiscal 2024, the Monthly Treasury Statement shows.
Democrats can hold hearings and demand documents. Trump can still move markets through “trade and tariffs, foreign policy, and existing regulations”, Hui said.
The Senate confirms every Fed governor. Kevin Warsh became chair in May by 54 votes to 45, with John Fetterman the only Democrat in favour, CNBC reported. From January, any new nominee needs a Democratic Senate.
That matters for a Fed that is debating rises, not cuts. It held its range at 3.75% to 4% on 28 October, with two officials voting for a rise, and markets put a 71.3% chance on a rise on 9 December, Central Bank Watch shows. Jesper Koll of Monex told Reuters “the market’s perception of greater Federal Reserve independence is going to come to the fore”, and that the result would be, at the margin, “dollar positive”.
Midterms have not been bad for shares. The S&P 500 was higher a year after every one of the 20 midterms since 1946, by 14.7% on average, by our calculation from S&P Dow Jones Indices data, as we wrote before the vote. This time the starting point is harder: a Fed leaning towards a rise and an AI trade already under strain.
The dates to watch:
Our view: the sweep matters most through the purse, not through new laws. Funding and the debt limit, the two sharpest tools of Congress’s power of the purse, give Democrats the leverage that vetoes take away. “I don’t think the big risk to markets is from the blue wave; it’s investors overreacting to a blue wave,” Michael Arone of State Street Global Advisors told Reuters.

The lek has not bought so many euros since at least 1995, when Eurostat's records begin. In September 2026 a euro cost 91.85 lek on average, the lowest monthly figure in those records. In 2019 it cost 123.01. Put the other way round, the lek now buys 33.9% more euros than it did in 2019, and 37.7% more dollars.
