Midterms Likely to Leave Tariffs and Energy Costs Steady
Importers and energy buyers should expect tariff and power-cost conditions to hold even as Congress's composition shifts.

Would you be worried if Congress ends up divided between the parties?
Analysts expect the November 3, 2026 US midterm elections to have limited impact on US markets, with polls pointing to a Democratic House takeover while the Senate race remains too close to call. For operators, the near-term read is that tariff and foreign policy stay under presidential control regardless of the outcome.
Why it matters
Divided government has been common, with split control across the presidency, House and Senate for more than 60% of the past 50 years, so a shift in Congress is not unprecedented for markets. Both parties have a stated interest in lowering energy prices, which is one reason analysts expect energy costs to be largely unaffected by the outcome.
Split political control across the presidency, House and Senate has existed for more than 60% of the past 50 years, a base rate analysts cite when discussing midterm effects. Headline inflation as measured by PCE has risen to 3.6%, a figure that is shaping rate expectations even as the Senate outcome remains open.
The players
Donald Trump
Current President of the United States, whose pre-midterm power and control over foreign and tariff policy are central to the market outlook.
The details
Analysts' reasoning rests on the idea that a divided Washington tends to slow new legislation rather than reverse existing policy. Presidential control over foreign and tariff policy persists regardless of congressional results, so trade-related cost pressures for importers are not expected to be resolved by the midterms. A bipartisan permitting reform bill in the Senate is the kind of measure that could still move in a divided Congress, while the pace of broader legislation would likely slow.
Timeline
November 3, 2026: US midterm elections held.
November 4, 2026: President Trump's unlimited pre-midterm power ends.
December 2026: Analysts anticipate a Federal Reserve rate hike tied to PCE inflation.
Market Landscape
Over the past 50 years, divided control of the presidency and Congress has held for more than 60% of the time, a pattern analysts cite to argue against a dramatic market reaction. Five of the six best third years of a presidency for S&P 500 capital returns came when the president faced an opposition-controlled Congress.
Operators should not expect a midterm-driven change in tariff or foreign-policy costs, since those remain under presidential control. Businesses with exposure to interest-rate-sensitive financing should watch the December rate decision, and procurement teams should plan for energy costs that analysts expect to be largely unchanged.
The takeaway
A divided Congress would likely slow new legislation, so operators should plan around the status quo rather than expecting sweeping regulatory change. Track the December Federal Reserve decision and the final Senate composition, as both will shape financing costs and the policy environment.
What happens next
A Federal Reserve rate hike is anticipated in December 2026, a decision analysts expect PCE inflation to influence, and the final Senate composition will be settled as that race resolves.
