What happened
S&P 500 financial stocks fell 6.3% in September through Tuesday, led by Blackstone (BX) down 21% and BlackRock (BLK) down 8%, as the 10-year Treasury yield hit 5.29% and raised borrowing costs. That makes financials the worst-performing part of the S&P 500 this month and their weakest month since March 2023 (per). A bond yield is the interest the government pays to borrow, and higher yields make loans costlier. The 30-year yield touched 5.61%, its highest level since 2002. The wider S&P 500 slipped 0.16% on Tuesday.
Why it matters
S&P 500 financial stocks include banks and money managers that many people own through retirement funds. When bond yields rise, borrowing gets more expensive, which can cut demand for loans and hurt firms like Blackstone and BlackRock. Rising yields also pay savers more on safe bonds, so investors may move money away from riskier stocks.
