Morgan Stanley says the recent jump in consumer prices may crest within weeks, with inflation expected to peak around May or June as several forces converge. If that forecast holds, the timing matters because higher prices in the near term could keep monetary policy tighter and squeeze household budgets through the summer.
Why inflation could top out soon
Michael Gapen, Morgan Stanley’s chief US economist, told Bloomberg he sees the United States passing through a period of intense, but short-lived, upward pressure on prices. Three main factors are pushing headline and core inflation higher right now, and their combined effect is likely to produce the high point in annual inflation sometime this spring or early summer.
- Tariff pass-through: Costs from tariffs implemented during the Trump administration are still working their way into retail prices. That effect has become visible in categories such as clothing, lifting core inflation — which excludes food and energy — above recent readings to about 2.8% year-over-year.
- Energy shock: The conflict in Iran has driven crude prices higher, translating into a sharp rise in energy costs. Energy inflation jumped roughly 18% year-over-year in the most recent Consumer Price Index report, with gasoline up more than 28% over the same period — a large share of the overall increase.
- Housing data lag: Shelter costs are now accelerating after a pause in government data collection late last year created a reporting gap. Recent monthly gains in shelter — about 0.6% in April — reflect a catch-up effect rather than a fresh, parallel shock.

Those three dynamics coincide at a moment when the Fed has less room for maneuver. Morgan Stanley’s view is that the central bank will likely keep interest rates unchanged through the rest of the year, at least until there is clearer evidence that the recent inflation surge has peaked and is reversing.
Markets have already adjusted their expectations. According to the CME FedWatch tool, investors now assign only about a 1% probability to a federal-funds rate cut in 2026 — a sharp drop from roughly 31% just a month earlier — underscoring how quickly pricing for policy has shifted as inflation has picked up.
What to watch next
In the coming weeks, three data points will be decisive: monthly CPI readings (especially shelter and core measures), oil and gasoline price trends, and any fresh signals from the Federal Reserve about its policy outlook. For households, a short-lived peak still means higher costs in the immediate term; for markets, the timing of the slowdown will determine whether expectations for future rate cuts are restored.
In other words, even if the worst of this inflationary rise is near its peak, the near-term consequences are real — both for everyday budgets and for the path of interest rates.
