Fed Chair Kevin Warsh and the FOMC Just Fired a Warning Shot at the Second-Priciest Stock Market in History

The Federal Reserve raised rates 25 basis points to 3.75%-4.00% on September 16, 2026, and the FOMC signaled more hikes are expected before year-end. Fed Chair Kevin Warsh and the committee voted unanimously, leaving no dissent to soften the message.

The source ties the tightening to persistent inflation driven by three named factors: tariffs, the Iran war, and energy supply disruptions. That combination keeps policy pointed toward restraint rather than relief.

The risk lands on equities. The article describes the stock market as the second-priciest in history, with valuations near dot-com bubble levels. It also notes heavy dependence on AI infrastructure investment financed by debt. Interpretation: higher borrowing costs raise the price of that financing, which could slow the spending that has supported growth-oriented valuations. Nasdaq-heavy exposure such as ONEQ sits closest to that pressure point, since the AI buildout is the market's central growth narrative.

The unanimous vote matters. A united committee and explicit forward guidance reduce the odds of a quick pivot, so any hope for near-term rate relief looks misplaced against the stated path.
