Oil’s return above $100 a barrel has revived fears that inflation could accelerate again in the United States. Investors have responded by sharply increasing the probability of a Federal Reserve rate hike next week, even as economists remain convinced that policymakers will wait.

The Fed will meet on July 28–29 and announce its interest-rate decision on Wednesday, July 29. Its benchmark rate currently stands at 3.50–3.75 percent.

Markets and economists are sending different signals

By July 24, futures markets placed the probability of a quarter-point rate increase at 38 percent, up from about 13 percent a week earlier. Holding rates steady remained the more likely outcome, but the rapid change showed how strongly the oil shock had altered market expectations.

Economists are considerably less convinced.

All 104 forecasters surveyed by Reuters expected the Fed to leave rates unchanged at its July meeting. Seventy-eight also predicted no change through the end of 2026.

The divide reflects two different assessments of the current risk. Markets are reacting to the possibility that the energy shock will persist. Most economists appear to believe the Fed will wait for clearer evidence that higher oil prices are spreading into the wider economy.

Higher oil prices complicate the Fed’s decision

Brent crude rose 7 percent on July 23 to settle at $100.69 a barrel, its first close above $100 since May. Prices retreated the following session after reports of a possible diplomatic effort to revive US-Iran negotiations, underlining how quickly the outlook can change.

The immediate concern for the Fed is not the price of oil alone, but whether higher energy costs begin feeding into transport, manufacturing, food and consumer prices.

Inflation is already running above the central bank’s target. The Fed’s preferred measure, the Personal Consumption Expenditures price index, increased 4.1 percent in the year to May. Core PCE inflation, which excludes food and energy, stood at 3.4 percent.

June consumer-price data offered some relief. Headline inflation eased to 3.5 percent and core inflation fell to 2.6 percent. Energy prices, however, were 15.7 percent higher than a year earlier, largely because gasoline prices had risen 26.7 percent.

That leaves Fed Chair Kevin Warsh with an uncomfortable choice. Raising rates immediately could put additional pressure on economic growth. Waiting would give policymakers more time to judge whether the oil surge is temporary, but it could become harder to justify if energy costs continue pushing inflation higher.

A July pause remains the central expectation. The bigger market signal may therefore come from Warsh’s press conference, where investors will look for clues about whether the Fed is preparing to raise rates in September or later in the year.
