Kevin Warsh Faces 3.9% Inflation Expectation Test on Day One

On the day Kevin Warsh was sworn in as Federal Reserve chairman, the University of Michigan consumer sentiment survey delivered a record low reading and a jump in long-run inflation expectations to 3.9% in May from 3.5% in April. That number sits well above the 2024 range of 2.8% to 3.2% and marks a clear break from the anchoring the Fed has leaned on to justify holding rates steady.

For commodity traders, the shift matters because it changes the Fed's reaction function. A central bank that tolerates supply-driven price spikes can allow oil and gold to rally. A central bank that fears unmoored expectations will hike into the shock, strengthening the dollar and crushing demand for risk assets. Warsh's Fed now faces that choice in real time, with the Iran war and Strait of Hormuz closure keeping crude elevated.

The 3.9% Long-Term Expectation: A Self-Fulfilling Mechanism

The naive read of a 3.9% long-term expectation is that consumers are simply extrapolating higher gasoline prices. The better market read is about the self-fulfilling mechanism. When households believe inflation will stay high, they demand higher wages. Firms pass those costs through. The Fed loses control of the inflation process even after the original supply shock fades.

The Sequence of Shocks

Fed Governor Chris Waller described the exact risk in a speech hours before the survey dropped. He warned that a series of positive price shocks – first tariffs, now oil – can change consumer psychology even if each shock is viewed as transitory. “If people do not know the true inflation generating process and see a sequence of positive price shocks, they may infer that the next price shock is more likely to be positive than negative,” Waller said. “This view can lead them to raise their inflation expectations even though they may also believe the recent shocks are transitory.”

Key insight: The Fed came within a quarter point of its 2% target last April, right before tariffs hit. The cumulative effect of two policy-driven supply shocks is what cracks the anchor, not the magnitude of any single one.

Waller's Red Line

Waller made the threat explicit: “If I believe inflation expectations start to become unanchored, I would not hesitate to support an increase in the target range for the federal funds rate.” He added that such action is premature now. The conditional reshapes the risk profile for every rate-sensitive asset.

Kevin Warsh's First Test: Watching the Sequence

Warsh inherits a situation where the University of Michigan survey shows year-ahead expectations inching up to 4.8% from 4.7% in April. The overall index fell for the third straight month to a fresh record low, undercutting levels seen during the 1970s oil crisis. The record low sentiment reinforces that consumers are already strained.

The Political Dimension

The survey's partisan breakdown makes the political story harder to spin. Long-term inflation expectations among Republicans are now more than double what they were in February 2025, right after Trump returned to the White House. Independents also drove the surge. The rise in long-term views is not a partisan protest by Democrats. It reflects a broader erosion of confidence.

“Critically, consumers appear worried that inflation will increase and proliferate beyond fuel prices, even in the long run,” Surveys of Consumers Director Joanne Hsu said in the University of Michigan report.

Strait of Hormuz Closure Keeps Oil Premium Alive

The current oil spike is tied to the Iran war and the continued closure of the Strait of Hormuz. Unlike the tariff shock of early 2025 – which the White House partly reversed and the Supreme Court later struck down – a military conflict does not end by executive order alone. President Trump cannot unilaterally reopen the strait. This makes the supply disruption more persistent than the previous waves of inflation.

Affected Assets: Gold, Crude, and the Dollar

Next Catalysts: CPI and Strait Evolution

The next CPI print will confirm whether the oil spike is feeding into core goods and services. Waller said he is “simply sitting and watching” how the conflict and data evolve. The University of Michigan final reading at month-end will either stabilize or further unhinge expectations.

Next FOMC meeting: No date given in the source, the market will price in the odds of a hawkish shift based on the next two inflation reports.

Strait of Hormuz negotiations: Any diplomatic development will directly move crude futures and, through them, inflation expectations.

What Would Reduce the Risk

Ceasefire in Iran and reopening of the Strait of Hormuz would cut oil prices and let year-ahead inflation expectations drop below 4%.

Actual core inflation prints showing deceleration despite higher energy costs would validate the “transitory” narrative and let the Fed stay on hold.

Warsh delivering a clear signal that the Fed will “look through” the oil spike if long-term expectations re-anchor could calm markets.

What Would Make It Worse

Long-term expectations rising above 4% in the June survey would trigger Waller's red line and force a rate hike discussion at the next FOMC meeting.

Another supply shock – disruption in Russian energy exports, a new tariff round – would compound the sequence of positive price shocks that Waller described.

Wage data showing an acceleration in average hourly earnings would confirm the self-fulfilling spiral.

Practical Takeaways for Commodities Traders

This is a regime test for the new Fed chair. Warsh's first major decision will be whether to treat the 3.9% long-term expectation as a statistical blip or a genuine unanchoring. The oil supply shock is the proximate cause. The Fed's response will determine whether commodities rally on inflation hedging or sell off on a dollar rally.

For now, the balance of risks tilts toward hawkish caution. The better trade may be long vol in gold and crude, positioning for a sharp move in either direction rather than betting on the prevailing trend. If the next CPI print confirms the survey's fear, expect the Fed to talk rates up – and that is a headwind for every commodity not directly tied to the strait closure.
