The Fed Under Siege: Inflation Hawks and Political Wolves Circle as Warsh Opens Door to September Hike

Two forces are converging on the Federal Reserve this August, and neither is particularly friendly to risk assets. On one side, persistent inflation is pushing Chair Kevin Warsh toward a potential September rate hike that markets had all but written off. On the other, President Donald Trump is renewing his assault on the central bank’s independence, resurrecting his bid to fire Governor Lisa Cook over unproven mortgage fraud allegations. The result is a central bank caught between economic reality and political pressure — and investors are starting to feel the squeeze.

Let’s start with the numbers that matter. According to the CME FedWatch tool, the probability of a quarter-point rate hike at the September 15-16 FOMC meeting has climbed to 56.7%, up from 54.4% just a day earlier[reference:0]. This shift follows a Financial Times report revealing that Warsh is prepared to support higher rates if upcoming inflation data runs hot[reference:1][reference:2]. The Fed held its benchmark rate at 3.5% to 3.75% in July, but three policymakers already dissented in favor of an immediate increase[reference:3]. This is not a unified doveish front — it is a committee fracturing along hawkish lines.

Why the sudden hawkish pivot? The inflation backdrop remains stubbornly elevated. Headline PCE inflation reached 3.7% in June, while core PCE sat at 3.3% — both well above the Fed’s 2% target[reference:4]. In fact, PCE inflation has exceeded that target for over five consecutive years[reference:5]. Oil prices surged roughly 21% in July after Iran-related conflict disrupted energy markets, threatening to lift consumer inflation broadly[reference:6]. Long-term inflation swaps still imply average inflation of about 2.4% over the next five years, and 30-year Treasury yields hover near 20-year highs[reference:7]. The bond market is sending a clear signal: inflation expectations are not anchored.

The immediate test comes on August 12, when the Bureau of Labor Statistics releases July’s Consumer Price Index[reference:8]. A hotter-than-expected print could solidify the case for a September hike, followed by producer prices on August 13 and the August employment report before the final decision[reference:9]. Five major inflation reports will land before policymakers gather[reference:10]. The market is bracing for volatility, and rightly so.

If rates do rise, the impact on risk assets will be uneven but broadly negative. Higher rates would pressure richly valued technology stocks, real estate, utilities, and other long-duration assets while supporting the dollar and short-term yields[reference:11]. The S&P 500 and Nasdaq Composite have historically suffered corrections after the first hike in a tightening cycle[reference:12]. With the S&P 500 recently hitting new highs and the Dow closing above 54,000 for the first time, valuations are extended[reference:13]. The Fed is becoming harder to read at precisely the moment stocks are getting more expensive[reference:14].

Yet the inflation story is only half the drama. On the political front, Trump has renewed his push to remove Fed Governor Lisa Cook, the first Black woman to serve in that role[reference:15]. The White House sent Cook a letter this week, giving her 21 days to respond to unproven mortgage fraud allegations—allegations her attorney has called “baseless”[reference:16][reference:17]. This is Trump’s second attempt; the Supreme Court blocked his first effort in June with a 5-4 ruling, finding that he had failed to afford Cook due process[reference:18][reference:19].

The timing is telling. Trump has repeatedly raged against the Fed for not lowering interest rates more dramatically[reference:20]. After his first attempt to remove Cook, he expressed a desire to have a “majority” on the central bank’s board[reference:21]. Now, with three of the seven sitting governors already his appointees, he is testing whether he can bend the Fed’s independence to his will. Cook’s lawyer, Abbe Lowell, framed the move precisely that way: “No matter what President Trump tries to do next, this much is clear under the facts and Supreme Court precedent — there is no valid cause for removing Governor Cook”[reference:22].

The legal question is significant. A court ruling on the merits of Trump’s argument would set a precedent on the circumstances under which a Fed board member can be fired, which is legally allowed only when there is “cause”[reference:23]. No president since the central bank’s founding in 1913 had sought to oust a Fed governor before Trump[reference:24]. This is uncharted territory, and it comes at a moment when the Fed can least afford distraction.

Amidst this turmoil, the Federal Reserve Bank of Philadelphia is sending Outreach Economist Ryo Tashiro to Milton, Pennsylvania, on September 18 for a seminar on “National & Regional Economic Developments”[reference:25]. The event will cover the Fed’s role, consumer trends, labor market conditions, and the inflation outlook[reference:26]. It is a reminder that while Washington plays politics with the central bank’s independence, the Fed’s regional economists are still doing the unglamorous work of understanding the real economy.

For crypto markets, the macro picture is mixed. Bitcoin is trading at $65,203, up 0.3%, while Ethereum sits at $1,923, up 0.1%. The Fear & Greed Index reads 31 — squarely in “Fear” territory. Total crypto market cap is $2.31 trillion. Litecoin is the top mover among the top 10, up 1.6% to $46.37, while Cardano leads the losers, down 1.4% to $0.1974. BNB is up 1.4% to $607.58, and Solana is up 1.3% to $76.64.

The broader macro environment remains the dominant driver. If the August 12 CPI print comes in hot, the odds of a September hike will rise further, likely pressuring risk assets across the board. If inflation surprises to the downside, the hike narrative could unwind just as quickly[reference:27]. But the political uncertainty surrounding Cook’s fate adds another layer of complexity. Markets thrive on predictability; the Fed is currently offering anything but.

Investors should brace for a volatile August. The inflation data will dictate the Fed’s next move, but the political assault on the central bank’s independence will determine whether that move is seen as legitimate or merely another front in an ongoing war. Either way, the Fed is under siege — and markets are caught in the crossfire.
