Last Wednesday, the Federal Reserve raised interest rates for the first time since July 2023 — a quarter point, to a range of 3.75 to 4 percent. The vote was unanimous, and that includes the man who led it. Kevin Warsh was handpicked by President Trump to run the Fed and deliver lower rates; Trump joked earlier this year that he would sue him if he didn’t. Instead Warsh, a career inflation hawk, spent August telling the Jackson Hole conference that responsibility for 65 months of elevated inflation “sits squarely with the central bank” — and then hiked.
The projections released with the decision point one way. The median Fed official expects one more increase before year-end, and officials raised their forecast for headline inflation this year to 3.7 percent. The driver is energy: prices pushed up by the Iran war, which Warsh admitted the Fed has no power to fix. Markets absorbed the message the hard way. The 10-year Treasury yield topped 5 percent for the first time since 2007, and the average 30-year mortgage has climbed above 7 percent.
The President answered within hours, in capital letters: “LOWER THE INTEREST RATES FOR THE UNITED STATES OF AMERICA, AND FAST!” He has said rates should be 1 percent. Asked at his press conference how Trump would take the news, Warsh declined to speculate: “I am not a Wall Street newsletter.” The midterm elections are seven weeks away.
This is not a story about a personality clash between a president and his appointee. It is a structural collision — one mapped in detail by an investor who spent decades studying how empires rise and fall.
The book that maps the collision
Ray Dalio is the founder of Bridgewater Associates, one of the world’s largest hedge funds. In 2021 he published Principles for Dealing with the Changing World Order: Why Nations Succeed and Fail, a study of the last 500 years of history through the rise and decline of the Dutch, British, and American powers. Its core idea is the “Big Cycle”: empires move through a long arc driven by three interlocking cycles — debt and money, internal order and disorder, external order and disorder.
Dalio breaks the internal cycle into six stages. Stage 5 is the late stage: a country carrying enormous debts, printing money to service them, with wide wealth gaps and rising populism on both political flanks. What defines Stage 5 is that the remaining choices are lose-lose. Stage 6 is what he calls the period of great internal conflict. The question his framework asks about any Stage 5 country is simple: do the rules hold?
The lose-lose choice
Here is the trap in mechanical terms. A late-cycle country has borrowed heavily and inflation has arrived. Its central bank now faces two bad options. Keep money easy to please the government and relieve debtors, and the currency weakens while inflation compounds. Tighten to defend the currency, and the economic pain lands on households, businesses — and the government’s own borrowing bill.
That last part is what makes this week’s hike so cyclically loaded. The US national debt crossed $40 trillion last month, and its average interest rate has more than doubled since 2021, to 3.4 percent; interest is already the government’s second-largest expense after Social Security. Every hike Warsh makes to fight inflation raises the cost of carrying the debt that sits underneath the inflation problem. The cure feeds the disease. That is not a policy error. In Dalio’s framework, it is what Stage 5 feels like from the inside: there is no clean move left on the board.
On Wednesday, Warsh chose the currency.
When stability triggers disorder
Dalio’s research shows that late in the cycle, the mechanisms used to preserve stability become the triggers of conflict. The Fed is raising rates to stabilize prices. But in a polarized country weeks from an election, that stability arrives as pain — and the demand for easy money is, in Dalio’s telling, the classic populist response to a debt cycle’s late stage. Through this lens, the President’s all-caps fury is not mere politics. It is the internal disorder cycle expressing itself exactly on schedule.
Honesty requires noting what cuts the other way. The hike was unanimous — the institution did not fracture. And the hawk asserting the Fed’s independence is the President’s own pick, which is the system working, not breaking. Dalio’s framework does not say Stage 5 must end in Stage 6. It says the transition happens when the rules of the system stop being respected. So far, they are holding.
What to watch next
Ignore the next quarter point; watch the response to it. The first tell is language from the White House about the Fed’s mandate — moves to strip its independence, purge the board, or install loyalists would mark the shift Dalio’s readers dread. The second tell is the projected second hike. The dot plot says one more increase is coming this year, into the teeth of the midterms and against the stated wishes of the President. If Warsh delivers it, central bank independence has passed a real test. If the hike quietly evaporates under pressure, mark the date.
And note what sits underneath it all. The inflation forcing this confrontation is largely Hormuz inflation — the energy shock this newsletter traced through Yergin’s The Prize five weeks ago has now traveled from the strait to the CPI to the Fed’s boardroom to the President’s feed. Dalio’s cycles are not separate stories. They are one story, arriving in installments.
The tragedy of the Big Cycle is that the choices made to save the system are often the ones that accelerate its strain. The Fed raised rates to save the dollar. Whether it also lit the fuse on the next great internal struggle is the question the rest of 2026 will answer.
