Several headwinds threaten to end the Trump bull market, with the Federal Reserve emerging as a potential surprise culprit. The stock market's remarkable 57% surge under Trump's first term and continued 14-16% gains since January 2025 stem from tax cuts, AI-driven growth, and favorable policies. However, the Fed's credibility is crumbling. Seven months of deep division among its 12-member committee, featuring frequent dissents and conflicting rate views, has paralyzed policy. This lack of clarity directly impacts Wall Street, creating uncertainty just as President Trump's nominee to replace Fed Chair Powell, Kevin Warsh, promises further disruption by pushing for balance sheet reduction.

Higher borrowing costs from aggressive Fed action or Warsh's policies could cripple the market's momentum. While corrections are inevitable, the long-term outlook for equities remains robust, with S&P 500 bull markets lasting far longer than bear markets on average.
