US stock futures turned lower on Monday as US-Iran tensions resurfaced and concerns about AI safety intensified ahead of an economic data-packed week, with Dow futures falling 0.3%, S&P 500 futures dropping 0.4%, and Nasdaq-100 futures dipping 0.9%. Markets were on edge after President Trump rejected Tehran's proposal to reopen the Strait of Hormuz and end the war, with officials back at the negotiating table and Trump saying talks would resume this week.
The rejection sparked broader concern over energy and supply chain disruption: shorter-maturity Treasuries led losses with the rate-sensitive two-year yield climbing five basis points to 4.90%, and the benchmark 10-year yield advanced four basis points, erasing Friday's decline. The timing coincides with Saudi Arabia's capital coming under attack from Yemen's Houthis over the weekend.
Consumer sentiment provided further headwinds: the University of Michigan's consumer sentiment index improved slightly to 48.1 in September from a preliminary reading of 47.8 but remained near historically weak levels, with views of current and year-ahead personal finances deteriorating around 10%, while year-ahead inflation expectations rose to 4.6%, the highest since June. The short-term outlook for business conditions deteriorated sharply amid renewed concerns that elevated fuel prices and escalating trade disputes could weigh on the broader economy.
This week brings critical economic data and Fed speeches to test whether strong corporate earnings and tech optimism can overcome severe geopolitical friction and high borrowing costs, with interest rate sensitive sectors such as banks, real estate, small caps and consumer facing companies firmly in the spotlight.
Consumer sentiment sits at 48.1, near historic lows, with the University of Michigan survey showing households still expect inflation of 4.6% over the next year and long-term borrowing costs climbing, with the 30-year mortgage rate above 7% and the 10-year Treasury yield above 5%. The short-term outlook for business conditions deteriorated sharply; sentiment weakened across the political spectrum, with Republicans' confidence down 20% from January and Democrats' down 13%. This week brings September nonfarm payrolls and PCE inflation data, with consensus expecting NFP gains of 90k versus 162k in August, with the unemployment rate expected to remain at 4.1% for a third consecutive month.
Northern Star Resources Ltd rejected a takeover offer from Gold Fields Limited, valuing it at up to $38.7 billion, citing undervaluation and high completion risk, with the offer representing a 22% premium to its pre-offer price. The offer comprised 0.3125 new Gold Fields shares plus $7.25 cash per Northern Star share, with an implied value of $27.00 per share based on September 11 Gold Fields close, and implied equity value of $38.7 billion initially. Northern Star said the 'opportunistic' offer comes with a material equity component exposing shareholders to new jurisdictional and operational risks, with 'onerous' conditions including a hard exclusivity period with no fiduciary out and needing South African Reserve Bank approval.
Microsoft is merging the consumer and workplace versions of its Copilot AI assistant into one product aimed at corporate customers, ceding the crowded market for personal chatbots to OpenAI, Alphabet's Google and Meta; the result of a six-month engineering effort, the latest iteration has absorbed the separate version for home use, adopting some of its slick design features. The launch effectively ends Microsoft's two-year effort to build a 'personal AI companion,' with Charles Lamanna, a Microsoft executive, telling customers at a private preview event: 'We're not going to build a Copilot that's like your personal companion'. In policy news, Australia's Senate has asked OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei to appear before an inquiry examining AI regulation and its broader impact, following a reported breach involving an OpenAI agent accessing Australian government systems.
President Donald Trump said Saturday he rejected a deal from Iran to reopen the Strait of Hormuz as Saudi Arabia's capital came under attack from Yemen's Houthis over the weekend. Trump was rejecting an Iranian plan to reopen the Strait of Hormuz, with the Iranian proposal similar to a memorandum of understanding agreed upon by the U.S. and Iran back in June. Iran initially closed the strait after the U.S. and Israel attacked Iran on Feb. 28, and the repeated closures have caused major disruptions to the world's oil supply. In separate regulatory developments, the Federal Trade Commission released a proposed enforcement policy statement concerning businesses' use of consumers' personal data to set individualized prices, cautioning that such practices may violate Section 5 of the FTC Act unless businesses clearly and conspicuously disclose that a price is personalized.
For small and mid-sized business owners, this week brings converging headwinds that will shape planning through year-end. Consumer expectation of 4.6% inflation over the next year is the highest since June, signaling that price pressures will persist in supplier costs, employee wages, and financing. Simultaneously, consumer outlook for business conditions deteriorated sharply amid concerns that elevated fuel prices and escalating trade disputes could weigh on the broader economy, meaning demand from household and commercial customers is likely to remain soft. Small business operators dependent on imported goods or energy-intensive operations should monitor the Strait of Hormuz and tariff developments closely, as Trump's rejection of Iran's deal to reopen the strait keeps shipping disruptions and energy volatility alive.
With mortgage rates above 7% and Treasury yields above 5%, and interest rate sensitive sectors such as banks, real estate, small caps and consumer facing companies firmly in the spotlight, access to capital remains expensive. Businesses should lock in financing where possible before this week's economic data (jobs report Friday, PCE inflation Thursday) potentially trigger further rate decisions. Consumer sentiment at 48.1 and deteriorating household finance views mean retail and service operators should prepare for continued hesitation; focus on operational efficiency and pricing power over volume growth.
