The Impact of the United States' Midterm Elections on the US and the World

In this year's midterm elections in the United States, Democrats won control of both the House of Representatives and the Senate, delivering a major setback to President Donald Trump and ending unified Republican control of Washington. Democratic gains extended into Republican strongholds, reflecting voter dissatisfaction over living costs, the Iran war and the administration’s performance. The breadth of the victories demonstrated a shift beyond traditional battleground states.

The new Congress takes office in January 2027, ushering in two years of divided government in Washington. Until then, Republicans retain a window to pursue priorities before their congressional majorities end.

 

THE IMPACT ON US POLITICS — A NEW BALANCE OF POWER

• Democrats will gain stronger powers to scrutinize the Trump Administration, including congressional investigations, hearings and greater influence over federal spending. Their Senate majority will also allow them to block presidential nominees.
• Major legislation will require more negotiation and compromise, increasing the likelihood of gridlock over politically divisive issues. Disputes over spending and executive authority could become recurring sources of uncertainty.
• The political focus will increasingly shift toward 2028, as both parties assess the election’s lessons. Republican candidates may reconsider their relationship with President Trump, while Democrats compete to define their party’s next presidential agenda amid divisions between centrist and left-wing Democrats.

 

THE IMPACT ON INTERNATIONAL AFFAIRS - MORE SCRUTINY AND CONTINUED UNCERTAINTY

• President Trump will retain substantial authority over diplomacy and military policy, allowing him to continue shaping international affairs. However, congressional scrutiny and funding decisions could place additional constraints on his administration.
• Policy toward Iran, Ukraine and Israel will face closer examination, particularly regarding military operations, assistance and weapons sales. US allies and adversaries will assess whether the election changes the US’ negotiating position or its ability to sustain commitments.
• A change in Congress does not guarantee an immediate foreign-policy reversal. The coming months could bring greater pressure for diplomacy, alongside continued uncertainty over how the administration responds to challenges abroad.

 

THE IMPACT ON THE US ECONOMY — TOUGHER NEGOTIATIONS OVER ECONOMIC POLICY

• Taxation, federal spending and affordability will become central political battlegrounds. Democrats will gain leverage through budget negotiations and are likely to demand concessions on policies affecting household costs and public services.
• The administration will retain important powers over tariffs and regulation, leaving businesses exposed to further policy changes despite divided government. Congressional opposition alone will not automatically reverse existing trade measures or administrative decisions.
• Sweeping economic legislation appears less likely, while disputes over federal funding could complicate business planning. Organizations should assess their exposure to government contracts, policy incentives and potential delays in spending decisions.

 

THE IMPACT ON THE GLOBAL ECONOMY — WATCH ENERGY, TRADE AND INVESTMENT

• Progress toward ending the Iran conflict could ease global energy and inflation pressures, supporting consumers and energy-intensive industries. However, meaningful relief would depend on restoring reliable production, shipping and access to supplies.
• Trade restrictions and uncertainty over US trade policy could continue to weigh on international business confidence. Companies should watch whether political pressure produces negotiations, further restrictions or changes in the enforcement of existing measures.
• Global companies should prepare for several possible economic outcomes, including changes in US demand, exchange rates and financing conditions. Investment and supply-chain decisions should account for both potential policy compromises and prolonged political confrontation.

 

WHAT TO WATCH — THE NEXT SIGNALS MATTER

• Watch the final congressional margins, leadership appointments and President Trump’s response. These will help indicate how cohesive the new majorities will be and whether Washington moves toward selective cooperation or sustained confrontation.
• Follow federal spending negotiations, developments involving Iran and Ukraine, and new tariff announcements. Decisions made during the transition could shape the operating environment before the new Congress begins work in January.
• Monitor whether financial-market reactions translate into lasting economic changes. Borrowing costs, energy prices, business surveys and investment announcements will provide more useful planning signals than a single day’s market movements.
