US Equities Extend Selloff on September 15 with S&P 500 Down 0.45 Percent and Nasdaq Falling 0.74 Percent as Treasury Yields Hit 2007 Highs

US equity markets extended their selloff on Tuesday September 15, with the S&P 500 down 0.45 percent to around 7,585, the Nasdaq Composite falling 0.74 percent to approximately 25,993, and the Dow Jones Industrial Average declining 0.73 percent or 382 points to 52,039 by midday, according to Yahoo Finance, Trading Economics, and TheStreet. The declines followed Monday's losses when the Nasdaq dropped 1.2 percent and the S&P 500 fell 0.7 percent, driven by AI development concerns and Bank of America CEO Brian Moynihan's warning that Q3 trading revenue would be flat year-over-year. The Tuesday session was marked by continued pressure from the 10-year Treasury yield hitting 5.04 percent, its highest since July 2007, and oil prices surging above $107 per barrel as Middle East supply risks intensified. Investors braced for the Federal Reserve's interest rate decision due Wednesday at 2:00 PM Eastern Time, with markets pricing in a 92 percent probability of a 25 basis point hike. Energy stocks showed relative strength amid the oil rally, while technology and financial sectors led declines. Bank of America shares remained under pressure after falling roughly 5 percent on Monday following Moynihan's revenue guidance at the Barclays Global Financial Services Conference, which projected investment banking fees between $1.6 billion and $1.8 billion for Q3, below the $2 billion analyst consensus.
