US midterms put Trump's tax and spending plans in the balance for markets
American voters go to the polls on Tuesday, 3 November to renew the US Congress in midterm elections that could curb Donald Trump's economic agenda for the last two years of his term. The question markets are pricing is whether Democrats can take one or both chambers now controlled by Republicans, making new tax cuts and spending packages harder to pass while stepping up oversight of the executive.
The arithmetic is tight. Republicans hold 218 House seats against 214 Democrats, one Republican-aligned independent and two vacancies, so Democrats need 218 to take the chamber. In the Senate, Republicans hold 53 seats against 45 Democrats and two independents who caucus with them; the opposition needs 51, and a 50-50 tie would favour Republicans because Vice-President JD Vance holds the casting vote. A Reuters/Ipsos poll completed on 26 October put Democrats on 47% and Republicans on 36% when registered voters were asked which party they would choose for Congress, with Trump's approval at 32% among adults surveyed.
Sidney Lima, an analyst at Ouro Preto Investimentos, said investors should watch three indicators: the dollar, yields on US government debt and the reaction of stock markets, because the result can shift expectations for public spending, taxes and inflation. A Democratic House is already widely expected, he said, while a Senate win is less anticipated and could trigger a sharper market reaction given the influence it would bring over presidential appointments. Fábio Murad, a consultant at Wiser Asset, said a Democratic House could reduce expectations of fiscal expansion and favour US Treasuries if long-term yields fall, while a Senate win would matter most for regulatory expectations in banking, technology and energy.
Felipe Passero, a partner at Jaguaretê Investimentos, flagged fiscal risk and advised caution on longer-dated bonds, saying Democrats are less fiscally conservative than Republicans and that tech, AI and oil face regulatory risk. Sector effects cut both ways: continued Republican control tends to favour banks, oil and gas, defence and smaller domestic businesses, while a Democratic advance could help renewable energy, healthcare and infrastructure but raise regulatory uncertainty for banks, drugmakers and traditional energy. Enrico Cozzolino, chief executive and strategist at Zermatt Partners, cautioned that antitrust pressure on big tech has support in both parties, and that for broad indices such as the S&P 500 the effect tends to be temporary.
A divided Congress also raises the risk of budget clashes, government shutdowns and fights over the debt ceiling. Murad said there is no automatically better winner for markets, with everything depending on the effect on growth, inflation and interest rates, and warned that a stronger dollar or a weaker one can swamp the return on US assets once converted back into another currency.
What it means for Pakistan: For Pakistani investors holding US equities, ETFs or funds, the midterms matter twice over: through the assets themselves and through the rupee-dollar rate. A gain on Wall Street can shrink or vanish in rupee terms if the dollar weakens against the Pakistani currency, so the sector exposure of a portfolio and the exchange rate both deserve attention. Any shift in US fiscal policy also feeds through to Treasury yields and the dollar, which shape the cost of Pakistan's external financing and the import bill, while a Congress that takes a harder line on big tech and AI regulation would affect Pakistani savers exposed to those stocks through international funds.
