US Midterms 2026 Part 1

美国中期选举 2026 第 1 部分
Core conclusion · Tlines extraction
OCBC Research argues the 2026 US midterms are a contest of weakness: Democrats are favoured to win both chambers, with the Democratic-sweep scenario carrying a 62% implied probability on Polymarket, but dissatisfaction with Republicans, not enthusiasm for Democrats, is doing the work. Trump's approval sits at 35.5% and Democrats lead the generic ballot 50.6% to 43.2%. Gasoline rose 60.2% since January and real average hourly earnings fell 0.4% YoY. A Democratic Congress could constrain, not overturn, Trump's agenda given veto power.

Key arguments
- The election is a contest of weakness, not a Democratic wave; internal progressive-centrist divisions and no clear 2028 standard-bearer weaken the Democratic coalition.
- A Democratic sweep carries 62% implied probability and would most constrain Trump's fiscal and tax agenda, but veto power caps any reversal of existing law.
- Gasoline up 60.2% from USD2.796 to USD4.478 per gallon and real wages down 0.4% YoY have pushed cost-of-living to the political foreground, with only 17% approving Trump's handling of it.
- A divided Congress more likely yields fiscal compromise and elevated borrowing than fiscal tightening, adding pressure on Treasury yields.
Key numbers
- Democratic sweep implied probability
- 62%
- Trump approval rating
- 35.5%
- Generic congressional ballot (Dem vs Rep)
- 50.6% vs 43.2%
- Regular gasoline price (Sep vs Jan)

Main risks
- A Democratic sweep could still produce fiscal loosening if Democrats trade war funding for domestic spending and direct fuel relief, keeping borrowing elevated.
- With divided Congress and fiscal pressure, the Fed may be pushed to respond to yields rather than set them, though OCBC does not treat this as the base case.
- Democratic Senate control may lower the credibility of near-term tariff escalation after the China trade truce expires on 10 January, but bipartisan strategic-sector restrictions mean Beijing should not read this as a broader softening.
Corresponding source evidence
On the flip side, political compromise could keep federal spending and borrowing elevated, adding to pressure on Treasury yields.
History provides Democrats with a powerful tailwind, as the president's party has lost House seats in 20 of the past 22 midterms and Senate seats in 15 out of 22 since 1938.
