For years, the stock market has been a stomping ground for wealth creation. Over the last six months, we’ve witnessed the widely followed Dow Jones Industrial Average (^DJI 0.26%) top 50,000, the broad-based S&P 500 (^GSPC 0.61%) surpass 7,000, and the technology-driven Nasdaq Composite (^IXIC 0.93%) exceed 24,000.
But as history has taught investors, there’s a price of admission to hop aboard the world’s greatest moneymaking machine. This “price” manifests as stock market corrections, bear markets, and unexpected crashes, nearly all of which are short-lived.
While Wall Street is focusing on the impacts of the Iran war and what that might entail for consumer/enterprise spending, an arguably bigger risk awaits: a shake-up at the Federal Reserve.

Jerome Powell’s term as Fed chair ends on May 15
President Donald Trump nominated Jerome Powell in 2017 to succeed then Fed Chair Janet Yellen. Powell was officially sworn in as Fed chair on Feb. 5, 2018, and was reappointed to a second term by former President Joe Biden in 2022.
But since President Trump was inaugurated for his second, non-consecutive term, he’s been hyper-critical of the Federal Open Market Committee’s (FOMC) approach to interest rates, which he’s pinned on Fed Chair Powell. Whereas Trump favors aggressive interest rate reductions to spur lending and encourage hiring, Powell has remained adamant that the 12-person FOMC will rely on economic data to guide its decisions. The writing has been on the wall for some time that Trump would not be nominating Jerome Powell for a third term.
Exactly two months from today, on May 15, 2026, Powell’s term as Fed chair will come to a close.
This shake-up, even though it’s been telegraphed for months, comes at a particularly tenuous time for the Federal Reserve and stock market.
Jerome Powell has the lowest average dissent rate per FOMC meeting among recent Fed chairs. That’s a reasonable metric to argue he has done a competent job leading the Federal Reserve.

On the one hand, Powell holds the distinction of having the lowest dissent rate among Fed chairs since 1978. This is to say that members of the FOMC have often shared a common vision for maximizing employment and stabilizing prices. When FOMC members vote in unison, it tends to appease investors.
But things have been markedly different over the last five FOMC meetings. Since the midpoint of 2025, each meeting has featured at least one dissenting opinion. Furthermore, the October and December meetings had dissents in opposite policy directions. Whereas the FOMC voted to lower the federal funds target rate (the overnight lending rate between financial institutions) by 25 basis points at both meetings, at least one voting member favored no reduction, while another pushed for a 50-basis-point cut.
Over the last 36 years, there have only been three FOMC meetings with opposite dissents, and two of those have occurred since Oct. 29, 2025. Historic division within the Fed threatens the credibility of America’s foremost financial institution — and it comes at a time when we’re witnessing a big shake-up at a prominent position.

Donald Trump’s Fed chair nominee, Kevin Warsh, may open a can of worms for Wall Street
Knowing that Powell’s time as Fed chair was winding down, on Jan. 30, President Trump nominated Kevin Warsh to succeed him. Warsh will need a majority of votes in the Senate Banking Committee and U.S. Senate for appointment.
Warsh would bring experience to the position, having served on the Board of Governors of the Federal Reserve from Feb. 24, 2006, through March 31, 2011. This means he was a voting member of the FOMC before, during, and after the financial crisis and was responsible for helping guide the U.S. economy through its biggest challenge since the Great Depression.
But in other ways, Kevin Warsh is far from a slam-dunk for Wall Street.
For instance, Warsh’s voting record during his previous five-year tenure raises concerns for a historically expensive stock market. Throughout the financial crisis, his commentary and voting record consistently favored price stability over concerns about unemployment. Favoring higher interest rates to keep inflation low earned Warsh the “hawk” label.

While some consumers might appreciate his stance on inflation, Wall Street is likely to be less enthused. Investors are expecting the Fed’s rate-easing cycle to continue at some point in 2026. If Warsh brings his hawkish stance to the party, it would throw a potential monkey wrench into rate-easing expectations.
Additionally, Trump’s Fed chair nominee has criticized the Fed’s aggressive balance sheet expansion in the wake of the Great Recession. Between August 2008 and March 2022, the Fed’s balance sheet — comprised mainly of U.S. Treasury bonds and mortgage-backed securities (MBSs) — grew tenfold to nearly $9 trillion. As of March 2, 2026, the Fed’s balance sheet topped $6.6 trillion.
Warsh believes in a hands-off approach to policymaking, whereby the Fed meaningfully deleverages its balance sheet and takes a passive role in the market. The problem is that selling Treasury bonds and MBSs would be expected to increase borrowing costs, including mortgage rates. Since bond yields and prices are inversely related, selling bonds would drive down prices and push up yields, thereby lifting borrowing costs.
In other words, a pricey stock market looking for lower borrowing costs to stimulate growth could be completely derailed by Kevin Warsh’s desire to have the Fed be a passive market participant.
Yes, the Iran war and Trump’s tariff and trade policy regularly make headlines — but they’re a potentially secondary concern for the Dow Jones Industrial Average, S&P 500, and Nasdaq Composite when compared to the impending shake-up at the Federal Reserve.
