WASHINGTON, November 9, 2026 — Democratic control of both chambers of the US Congress is creating new challenges for President Donald Trump’s economic agenda, with federal spending, trade policy and government borrowing emerging as potential areas of confrontation.
According to Reuters analysis published on November 4, the Democrats’ midterm election victory gives the party significant leverage over budget negotiations, even though the president retains important executive powers.
The new balance of power could affect economic policy over the remaining two years of Trump’s presidency.
Congress Controls Federal Spending
One of Congress’s most important responsibilities is approving federal spending.
Without agreement between lawmakers and the White House, funding disputes can disrupt government operations.
Democratic leaders will be able to use budget negotiations to seek changes to administration priorities.
However, Trump retains the power to veto legislation, and the Democrats do not hold sufficiently large majorities to override presidential vetoes on their own.
This creates incentives for negotiation while increasing the possibility of political deadlock.
Tariffs May Be Harder to Reverse
Trade policy is another area of disagreement.
Trump has relied on executive authorities to introduce tariffs affecting major trading partners.
Although Congress can influence trade legislation, the new Democratic majorities will not automatically be able to remove existing tariffs.
For businesses and foreign governments, this means that the election result does not necessarily produce immediate changes to American trade policy.
Canada, in particular, remains exposed to uncertainty over tariffs and cross-border commerce.
Debt and Borrowing Could Become Major Issues
Future negotiations over the federal debt ceiling could provide another source of congressional leverage.
The debt ceiling determines the legal limit on federal borrowing, making it a significant issue when government financing requires legislative action.
Disagreements could create uncertainty for financial markets and federal agencies.
However, divided government can also lead to negotiated fiscal compromises.
Technology Policy Under Scrutiny
Artificial intelligence investment is another area where congressional priorities may influence the economy.
The rapid construction of data centres has raised questions about electricity demand, public incentives and environmental regulation.
Lawmakers may examine tax measures and other policies supporting the sector.
Changes could affect investment decisions by major technology companies and infrastructure developers.
What Comes Next?
The Democrats’ congressional victory has altered Washington’s political balance, but it has not transferred executive authority away from the president.
The economic consequences will depend on whether the two sides negotiate compromises or enter prolonged confrontations.
For businesses, investors and international partners, the most important issues will be federal spending, tariffs, borrowing and regulatory stability.
The coming months will show whether divided government produces policy adjustments or greater uncertainty.
