What are today's top business/market headlines?

I'll fetch the latest business and market headlines for you.Gathering more details from key sources for a complete summary.Today’s top business and market headlines (September 14, 2026) center on an AI-related tech selloff, surging oil prices from Middle East disruptions, rising U.S. Treasury yields, and expectations for a Federal Reserve rate hike this week.[1]

U.S. Stock Market Performance

Major indexes closed lower but off session lows, with weakness concentrated in AI/semiconductor stocks while many other shares rose (a majority of S&P 500 stocks finished positive).[1]

Chipmakers and AI-linked names led declines (e.g., Nvidia fell over 3%; semiconductor ETFs dropped sharply, around 5%). Software and cybersecurity stocks gained (software sector ETF up ~4–5%; names like CrowdStrike and Palo Alto rose strongly) as traders rotated amid slowdown fears. Bank of America shares dropped more than 5% after CEO guidance pointed to weaker investment banking fees and trading.[2]

AI Development Slowdown Calls

AI-linked stocks tumbled after leading executives urged a coordinated slowdown in model development for safety reasons. Anthropic CEO Dario Amodei published a lengthy essay arguing for pacing capabilities advances so risk mitigation can keep up. OpenAI’s Sam Altman and Elon Musk echoed the concerns. This raised worries about reduced infrastructure demand and valuations.[1]

President Trump dismissed the calls as a “sick conspiracy,” emphasizing U.S. leadership over China and light-touch regulation. OpenAI also indicated its IPO is delayed beyond 2026.[3]

Oil Prices and Geopolitics

Oil surged on supply fears after drone attacks led Saudi Arabia to shut a key East-West pipeline (bypassing the Strait of Hormuz), with potential multi-week outages and Houthi-related pressures on shipping routes. Brent crude traded around $105–$106+ (briefly near $110), and WTI around $101–$102+. This continues pressures tied to broader Middle East/Iran-related tensions and has pushed U.S. gasoline prices higher.[4]

Bonds, Yields, and Fed Outlook

The 10-year U.S. Treasury yield briefly topped 5% (highest intraday since 2023, and levels not sustained since around 2007), driven by the oil/inflation scare and bond selling, before easing slightly to around 4.99%. The 30-year yield remained elevated.[2]

Markets heavily price in a 25 bp Fed rate hike this Wednesday (odds ~90%+), the first under the current setup, amid sticky inflation (recent CPI at 3.4% annualized) fueled by energy costs. Higher yields raise borrowing costs and pressure valuations.[5]

Other Notable Headlines

Markets are watching the Fed meeting closely, oil developments, and any follow-through on AI safety discussions. Sentiment is cautious amid the dual pressures of higher rates/energy costs and potential AI capex moderation.
