Investors are closely monitoring the US midterm elections as political uncertainty, concerns over artificial intelligence investment and renewed geopolitical risks influence global financial markets. Voting is underway in elections that will determine control of all 435 House seats, 35 Senate seats and 36 governorships. More than 57 million people had already voted early, according to Reuters.
The election outcome could influence fiscal policy, trade, technology regulation and the direction of US government borrowing. Investors are also assessing whether a potential Democratic gain in Congress could increase scrutiny of President Donald Trump‘s policies, including trade and military decisions.
Treasury Borrowing and Rising Bond Yields Remain in Focus
The US Treasury lowered its fourth-quarter borrowing estimate to $618 billion, down $10 billion from its August projection. The revision reflected a higher-than-expected opening cash balance, partly offset by weaker net cash flows. However, excluding the higher opening cash balance, borrowing requirements are $24 billion above the previous estimate.
The Treasury expects to borrow $800 billion in the first quarter of 2027, assuming an end-of-March cash balance of $1 trillion. It borrowed $742 billion in the third quarter, slightly above its August forecast of $739 billion. Investors are watching the upcoming refinancing announcement for signals on future Treasury auction sizes and government debt supply.
Bond yields have also moved higher. Eurozone government bond yields climbed alongside US Treasury yields and a modest recovery in oil prices. Germany’s 10-year yield rose 2.1 basis points to 3.316%, while Belgium’s 10-year yield increased 3.2 basis points to 4.428% after budget negotiations collapsed.
The US dollar weakened as investors assessed election uncertainty and questioned the sustainability of AI investment. The dollar index declined 0.12% to 101.684 after touching a one-month low of 101.426. Concerns over AI-related operating costs and funding requirements have added to pressure on technology sentiment.
AI Regulation and Geopolitical Risks Add to Market Uncertainty
BNP Paribas analyst William Bratton warned that Asian AI-related stocks could face pressure if Democrats perform strongly in the midterm elections. A sweeping Democratic victory could shift Washington’s focus towards AI safety, testing and industry standards, potentially increasing expectations of tighter regulation.
However, the impact on markets will depend on the final election result and the policy response. Corporate earnings and the ability of technology companies to commercialise AI are likely to remain important drivers of Asian technology stocks.
Geopolitical developments are adding another layer of uncertainty. Reports of US strikes on Iran’s Qeshm Island pushed oil prices higher, while investors assessed the potential impact on energy supply, inflation and global borrowing costs. A stronger Democratic presence in Congress could increase pressure for diplomatic solutions, but does not automatically mean that military tensions or oil prices will decline.
For investors, the key variables remain Treasury yields, the dollar, corporate credit spreads, inflation and the direction of US policy after the elections. Closely contested races may also delay clarity on the final political outcome.
