The financial markets are facing significant turbulence as rising U.S. Treasury yields raise alarms among investors. Recently, the 30-year Treasury yield has surged above 5%, prompting concerns about the implications of a proposed tax bill led by Republicans, which could exacerbate the federal budget deficit. A weak auction of 20-year Treasury bonds highlighted waning investor confidence, as demand fell short of expectations. Analysts warn that the increasing yields might signal a problematic outlook for equity markets, with major stock indices experiencing their worst decline in a month. This environment has led to fears that the bond market may not remain a safe haven amid escalating financial instability and growing worries about U.S. government debt.
