Inflation Surges, Fed Hawkish
Persistent Inflation Keeps Fed on Edge as Debate Intensifies Over Rate Hike Path
The Federal Reserve's preferred inflation gauge hit a three-year high in May, with the Personal Consumption Expenditures index rising 4.1% year-over-year — the first time it has crossed the 4% threshold since April 2023, according to Bureau of Economic Analysis. Core PCE, which strips out food and energy costs, climbed to 3.4%, up from 3.3% in April, keeping inflation well above the Fed's 2% target.
The report, released Wednesday morning, locks in expectations for tighter monetary policy. Markets now price a 69–70% chance of a rate hike by September, according to CME FedWatch. New Fed Chair Kevin Warsh has already signaled the shift, dropping the central bank's
A Supply Shock Rooted in the Iran War
The inflation surge is largely a supply-side story. The 2026 U.S.-Iran conflict sent Brent crude above $120 per barrel after the Strait of Hormuz closed in early March, according to S&P Global. The strait carries roughly 20% of global oil supply. That energy shock — with energy prices up 23.5% year-over-year in May — filtered through nearly every corner of the economy.
A ceasefire signed on June 18 has since pushed oil prices lower — down about 38.8% from their May peak. But economists warn the damage is not undone. ActionForex cited RSM chief economist Joe Brusuelas, who said core prices "will not retreat so easily" even as energy costs fall. Tariffs enacted earlier in the Trump administration have added a second layer of upward pressure, according to Reuters.
Consumer Spending Stayed Strong, Fueling Price Pressures
Despite high prices, Americans kept spending. Personal spending rose 0.7% in May, beating the 0.6% forecast. Personal income climbed 0.7% as well, topping the 0.4% estimate. The savings rate held at 3.0%, according to Bureau of Economic Analysis. Strong demand makes it harder for inflation to cool — if people keep buying, sellers have less reason to cut prices.
Goldman Sachs economists expect higher energy costs to eventually "erode household spending power" through the rest of 2026, according to Morningstar. For now, the data tells a mixed story: consumers are resilient, but that resilience may be part of what is keeping inflation elevated.
Warsh's First Big Test: Kill Forward Guidance, Signal Hikes
Kevin Warsh was sworn in as Fed Chair on May 22 and chaired his first FOMC meeting on June 17. The committee held rates at 3.50%–3.75% but removed its "easing bias" from the policy statement, according to Briefs Finance. Warsh cut the statement to just 130 words and scrapped forward guidance entirely. He said, "The Fed will act when the data calls for it, not when it wants to tip its hand."
The move marks a sharp break from recent Fed communication norms. Without a roadmap, every new data release — like Wednesday's PCE report — becomes a potential market-mover. Morningstar analyst Michael Kramer said the hot May reading effectively guarantees a rate hike will be "priced in" by markets for September.
Is May the Peak, or Just the Beginning?
Analysts are split on what comes next. The optimistic case rests on falling oil prices after the ceasefire and slowing monthly gains — headline PCE rose just 0.4% in May, and core PCE rose 0.3%. ActionForex cited Brusuelas saying inflation likely "peaked in May." J.P. Morgan's Bruce Kasman offered a harder warning: if the Strait of Hormuz reopening is delayed, core inflation could stay above 3% all year, per Yahoo Finance.
The structural case for sticky inflation centers on spending beyond energy. Defense outlays and an AI infrastructure buildout are both pushing prices higher independent of oil, according to Morningstar. President Trump, asked about possible rate hikes, said "whatever… it could happen," while insisting prices would fall "like a rock" now that the conflict is ending, according to Business Insider.
