The US dollar slid to a one-month low on Wednesday as Democrats secured control of both the Senate and the House of Representatives in the midterm elections, triggering investor anxiety over potential regulatory headwinds for artificial intelligence and broader economic growth. The greenback weakened against a basket of six currencies, with the euro and British pound both gaining against the dollar, while investors rotated capital into US Treasuries as a safe harbor against expected legislative gridlock.
Market Reactions to the Congressional Shift
- The US dollar index declined to a one-month low, with the euro and British pound registering notable gains against the American currency.
- The benchmark 10-year US Treasury yield fell 6 basis points to 4.906%.
- Gold prices rose 2.2%, pushing past $4,000 an ounce as safe-haven demand accelerated.
Treasury Yields Fall Amid Political Uncertainty
As political uncertainty gripped trading desks, bond markets experienced immediate downward pressure on yields. The yield on the benchmark 10-year US Treasury bond fell 6 basis points to settle at 4.906%, reflecting rising demand for government debt as bond prices advanced. According to Fox Business, the Fox News Decision Desk projected Democratic majorities in both chambers.

Speaking to Reuters, Saxo chief investment strategist Charu Chanana in Singapore explained that financial markets appeared to be factoring in the likelihood of a stronger performance by Democrats, a scenario that might dampen forecasts for future fiscal stimulus. Concurrently, traditional safe-haven assets captured substantial inflows. Gold prices climbed 2.2% to surpass $4,000 per ounce, mirroring institutional capital preservation strategies observed across international desks.
Technology Stocks Drop on Regulatory Concerns
Equities tied to the artificial intelligence infrastructure and technology sectors experienced significant turbulence. Futures trading initially pointed to steep losses for the tech-heavy Nasdaq, driven by investor concerns that a Democrat-controlled Congress would introduce stricter oversight and regulatory frameworks for data centers and large-scale AI deployment. CNBC reported that neocloud providers faced immediate downward pressure, with CoreWeave falling 3.6% and Nebius sliding 1%. High-profile figures aligned with the prior administration also absorbed losses in premarket action, with SpaceX down 4.8% and Tesla lower by 4.9%.

Conversely, European markets rallied during early trading hours, helped by a conciliatory tone from President Donald Trump regarding future cooperation with the incoming congressional majority. London’s FTSE 100 gained 0.2%, Germany’s DAX climbed nearly 0.6%, France’s CAC 40 advanced 0.4%, and Italy’s FTSE MiB jumped by almost 1.4%. Clean energy equities registered sharp gains on expectations that Democratic majorities would challenge regulatory rollbacks enacted under the Republican executive agenda, with Denmark’s Vestas Wind Systems rising nearly 5% and Ørsted surging 7.4%.

Historical Data Shows Market Resilience
Despite the immediate volatility in currency and tech equity valuations, institutional strategists evaluated the long-term historical implications of a divided government. Figures assembled by Ned Davis Research show that following 1930, the S&P 500 managed to climb toward the end of the year during five out of eight midterm cycles where the commander-in-chief’s party surrendered the House.
Kurt Reiman, head of fixed income at UBS’s Chief Investment Office, noted in a report cited by Yahoo Finance that sweeping policy changes remain constrained by Senate rules, party divisions, presidential veto power, and persistent federal deficits. While legislative gridlock is expected to define the rest of Donald Trump’s final term in office, executive authorities concerning trade tariffs, foreign policy, and existing regulatory frameworks continue to remain under the direct purview of the White House.
