The Fed's Impossible Choice: How the Iran War Killed the Rate-Cut Cycle

As Federal Reserve officials gather in Washington for their March 17–18 meeting, they confront an economic landscape that was virtually unrecognizable just three weeks ago. The U.S.-Israeli military campaign against Iran, which began on February 28 with strikes that killed Supreme Leader Ali Khamenei, has triggered the largest oil supply disruption in recorded history — and with it, a policy crisis that threatens to paralyze the world's most powerful central bank.

The Fed is expected to announce its decision at 2:00 p.m. ET on Wednesday, March 18. Markets are pricing in a near-certainty — 98.9% probability according to the CME FedWatch tool — that the Federal Open Market Committee will hold rates steady at 3.5%–3.75% [1]. But the real drama lies not in this meeting's decision, which is a foregone conclusion, but in what the Fed signals about where rates go from here — and whether policymakers have any good options left.

From Two Cuts to Maybe None

Before the first cruise missiles struck Tehran, the Federal Reserve's path for 2026 appeared relatively straightforward. Financial markets were pricing in two quarter-point rate cuts over the course of the year, a continuation of the easing cycle that brought the federal funds rate down from 5.33% in mid-2024 to its current level [2]. Inflation was cooling, if stubbornly, and the labor market showed signs of gradual softening that justified further monetary accommodation.

That calculus evaporated in a matter of days.

West Texas Intermediate crude oil surged from roughly $67 per barrel on February 27 to $119 by March 9 — a 77% spike in less than two weeks — as Iran's retaliatory closure of the Strait of Hormuz shut down the transit route for approximately 20% of global petroleum supply [3]. Though prices have retreated somewhat to around $95 amid diplomatic maneuvering and a record 400-million-barrel release from international strategic reserves, they remain more than 40% above pre-war levels.

The market's rate-cut expectations have been repriced accordingly. Traders in the fed funds futures market have taken even a September cut off the table and now see only one reduction coming — in December — with some analysts projecting no cuts at all in 2026 [4]. A small but growing minority of market participants, reflected in a 19.8% probability on the Market Probability Tracker, are pricing in the possibility that the Fed's next move could be a rate hike [5].

"Given our higher headline and core PCE inflation forecast, we have revised our baseline to show only one 0.25-percentage-point rate cut in 2026, likely in December," said Gregory Daco, chief economist at EY-Parthenon. "But it is entirely plausible that the Fed won't deliver any rate cuts this year" [1].

The Stagflation Trap

The Fed's dilemma is a textbook case of what economists call a "supply shock" — an external event that simultaneously pushes prices higher and output lower, forcing policymakers to choose which half of their dual mandate to sacrifice.

The inflation side of the equation is already flashing warnings. The Personal Consumption Expenditures Price Index, the Fed's preferred inflation gauge, rose 3.1% year-over-year in January on a core basis, accelerating from a 2.8% pace in November [1]. That was before the war sent energy prices spiraling. Gasoline prices have jumped nearly 80 cents per gallon from a month ago, with diesel approaching $5 a gallon — up $1.34 in the same period [6]. Those increases have not yet shown up in the official inflation data, but they will.

On the other side of the mandate, the labor market is deteriorating faster than anticipated. Employers shed 92,000 jobs in February, an unexpected decline that signaled growing fatigue in the hiring market [1]. Unemployment has crept up to 4.4% [7]. And those numbers, too, reflect pre-war conditions; the full economic impact of the oil shock — from higher transportation costs rippling through supply chains to consumer spending pullbacks — is still materializing.

This combination of rising prices and weakening employment is the hallmark of stagflation, the economic condition that bedeviled policymakers in the 1970s. "Any extended period of high energy costs threatens tipping the economy into a recession while also keeping upward pressure on inflation," Fortune reported, citing analysis from Deutsche Bank economist Jim Reid, who warned that "with each passing day it gets harder to argue that the disruption will only prove temporary" [7].

Oxford Economics has modeled two scenarios: if Brent crude averages $100 per barrel for two months, the impact shaves tenths of percentage points from GDP growth but avoids recession; if prices spike to $140 for eight weeks, global GDP contracts by 0.7% by year-end, with the U.S. facing what economists call a "temporary standstill" — rising unemployment alongside persistent inflation [7].

A Divided Committee

The internal politics of the FOMC are adding another layer of complexity. The committee has experienced unprecedented levels of dissent: each of the last five meetings has featured at least one dissenting vote, and at both the October and December 2024 meetings, dissents came in opposite directions — one member voting against a rate cut while another favored a deeper cut. That pattern has occurred only three times since 1990, and two of those instances were in the past year [3].

At the March meeting, the KPMG Fed primer projects two dissents in favor of a quarter-point rate cut. Governor Stephan Miran is expected to dissent for a fifth consecutive meeting, with either Governor Chris Waller or Governor Miki Bowman likely joining him [8]. The doves argue that the economy is already weakening and that the oil shock, while inflationary in the short term, will ultimately prove deflationary as it crushes demand. The hawks counter that cutting rates while inflation is reaccelerating would undermine the Fed's credibility and risk de-anchoring inflation expectations.

The most closely watched output of the meeting will be the quarterly Summary of Economic Projections — the so-called "dot plot" — which will reveal where each FOMC member expects the federal funds rate to be at year-end. The December dot plot showed a median expectation of one 25-basis-point cut in 2026 [9]. The March update will show whether the war has shifted the median higher, to zero cuts, or whether the committee remains split between easing and holding.

KPMG projects the Fed will postpone any cuts until September 2026, with only two reductions before year-end [8]. But even that forecast comes with enormous uncertainty bands. "The Fed's statement will likely flag Middle East tensions as threats to both inflation and employment objectives," the analysis noted — a diplomatic way of saying the central bank has no idea which way the economy will break.

The Warsh Factor

Complicating the picture further is the looming change in Fed leadership. Jerome Powell's term as chair expires on May 15, and President Trump has nominated Kevin Warsh, a former Fed governor, to replace him [10]. The nomination has been delayed in the Senate over an unrelated Justice Department investigation into Powell, but Warsh could take the helm as early as May or June.

The irony is thick. Trump chose Warsh partly because of his expected willingness to cut rates aggressively — a priority the president has been vocal about since his first term. But the war Trump launched has made those cuts far harder to deliver. Warsh's own record leans hawkish: he has advocated for aggressive balance sheet reduction, including selling down the Fed's $6.6 trillion portfolio of Treasury bonds and mortgage-backed securities, a move that would push borrowing costs higher [3].

"President Donald Trump's war on Iran likely makes those rate cuts harder to deliver," CNBC reported. "The war may be over by the time Warsh takes office in May or June," but if it isn't, the new chair will inherit an institution caught between a president who wants lower rates, an economy that may need them, and an inflation problem that makes them dangerous [10].

How This Differs from the 1970s

The specter of 1970s-style stagflation is dominating the economic conversation, but several structural differences offer cautious grounds for optimism.

First, the U.S. is now the world's largest oil producer and a top exporter. While the economy is not immune to global price spikes, it is far less vulnerable to supply constraints in the Middle East than it was when OPEC's embargo brought the country to its knees in 1973 [11]. American oil producers, in fact, stand to benefit from elevated prices even as consumers suffer.

Second, inflation, while above the Fed's 2% target, is nowhere near the double-digit levels that characterized the 1970s. The Fed's credibility on inflation, though tested, remains largely intact, which means long-term inflation expectations have stayed relatively anchored [11].

Third, the Fed has already been cutting rates from a restrictive level. The federal funds rate at 3.5%–3.75% gives policymakers more room to respond to a downturn than the near-zero rates that constrained them after the 2008 financial crisis.

But these structural advantages come with caveats. The oil shock is layered on top of Trump's 15% global tariffs, which were already adding to inflationary pressures before the war began [9]. The Strait of Hormuz carries not just oil but a vast array of commodities — fertilizer, LNG, chemicals, helium — whose disruption is cascading through global supply chains in ways that are difficult to model and impossible to predict.

What Comes Next

The Fed's Wednesday statement and Powell's press conference will be parsed for any shift in language about the balance of risks. Markets will focus on whether the committee characterizes inflation risks as "elevated" versus "balanced," and whether it acknowledges the oil shock as a potential threat to the employment side of its mandate.

But the honest answer is that the Fed is flying blind. The war is 18 days old. Its duration is unknowable. The Strait of Hormuz remains effectively closed. And the central bank's standard models — designed for an economy buffeted by predictable cycles of expansion and contraction — have no reliable way to incorporate the possibility that the world's most critical energy chokepoint could remain shut for weeks, months, or longer.

For American consumers already facing 30-year mortgage rates at 6.26% and gasoline approaching $4 a gallon nationally, the message from the Fed is likely to be unsatisfying: don't expect the central bank to ride in and save the day [12]. As one CNBC analyst put it, the era of the "Fed put" — the implicit promise that the central bank would ease policy whenever the economy stumbled — may be over, at least for now.

The rate-cut cycle that began in September 2024 and brought borrowing costs down by 175 basis points was supposed to continue gently through 2026, providing tailwinds for housing, hiring, and growth. Instead, the Iran war has left the Federal Reserve trapped between two bad options — a position that, if the conflict persists, could define American economic policy for the rest of the year and beyond.
