What does the April CPI mean? "New Fed Mouthpiece": Rate cuts are no longer a 2026 story, Waller is in trouble.

US April CPI inflation rose more than expected, dampening market hopes for Fed rate cuts this year. Nick Timiraos, known as the "new Fed reporter," said the April CPI report will not change the Fed's basic hawkish or dovish stance, but if similar data persists in the coming months, it will make dovish members advocating for continued easing more passive.

According to the US Bureau of Labor Statistics (BLS) on Tuesday, the April CPI rose 3.8% from a year earlier, the largest monthly year-on-year increase in nearly three years, exceeding the market expectation of 3.7% and visibly above March's 3.3%. Gasoline, grocery, rent, and airline prices all rose sharply in April. Inflation outpaced wages, with real average hourly earnings down 0.3% year-on-year, marking the first negative growth in three years.

Timiraos noted that the CPI report is the latest signal, indicating the previously priced-in rate cut expectations are no longer a viable outlook for 2026. This poses a tricky policy legacy for Kevin Warsh, who will take over the Fed next week. President Trump, who nominated Warsh as Fed Chair, has long made clear his strong desire for rate cuts.

Timiraos emphasized that the Fed's real concern is not the single month's CPI data itself, but rather the resurgence of public inflation expectations. He noted that if consumers and businesses start to believe high inflation will persist, firms will become more aggressive in raising prices, employees will demand higher wages, leading to a more stubborn "wage-price spiral." In such a scenario, even if the Fed sees an economic slowdown, it will be difficult to cut rates quickly.

Service sector inflation rises, dovish logic challenged

Timiraos focused his interpretation on changes in inflation structure. He said April CPI showed mild pressure on goods prices, apparently supporting the judgment that tariffs have not sparked a new round of price hikes—a key premise for Fed centrists evaluating future inflation.

However, service prices excluding energy and housing rebounded in April, complicating the dovish argument. The core scenario for doves was previously: inflation pressure would be confined to goods, reasonably explained as fading effects of tariffs, so no need for Fed rate hike discussion, allowing for continued easing.

Timiraos stressed that service sector inflation is harder to ignore because it usually reflects domestic demand—not just supply shocks. He specifically pointed to sharp increases in airfare, possibly from Iran war boosting jet fuel costs or broader domestic price pressure—making signals hard to identify and further clouding policy judgment.

Iran conflict impacts energy and supply chains

Many media outlets noted energy is still the core driver of the latest inflation uptick. Some reports said Middle East tensions and risks to Hormuz Strait transport pushed US gasoline prices higher in recent months, with April energy prices up 17.9% year-on-year—the biggest increase since 2022.

Other reports noted that the Iran conflict is profoundly affecting the US economy, with energy costs surging. BLS data show gasoline prices rose nearly 28% in the past two months. Grocery prices, rent, and airfares all posted substantial month-on-month increases, as did meat, dairy, and fresh produce. April grocery prices rose 0.7% month-on-month, the largest increase in nearly four years.

Wall Street insiders are generally concerned that energy shocks are spreading more broadly. Besides gasoline, transportation, food, and parts of manufacturing costs are also rising.

Bloomberg Economics economists say current US inflation is not just a "oil price issue" anymore, but is showing broader second-order effects, especially in rent and food.

Data show housing costs remain a key support for core inflation, and food prices are also up. Some analysts point out that rising energy prices drive up transport and agriculture costs, with food inflation usually lagging by several months.

Gus Faucher, chief economist at PNC Financial Services Group, stated, "The inflation we thought was under control is reaccelerating. This is a real issue. The longer inflation stays high, the more it pressures consumers."

Some reports cite economists as saying even if the current ceasefire agreement holds and Hormuz Strait reopens soon, prices may remain elevated in the coming months—oil production will take time to recover, and shipping logistics will also need gradual recovery. Additionally, rising fertilizer prices are expected to increase food bills, and high oil prices could drive up more goods and services via transportation costs.

Special distortions in airfare and rent data

In the April CPI data, airfares rose 2.8% month-on-month, hotel prices rose 2.8%—the biggest increase in 2024—overall services ex-energy and housing rose 0.5% month-on-month.

Rent data was affected by a statistical factor: Bloomberg data show housing costs rose 0.6% month-on-month in April, the biggest rise in over two years, partly due to statistical distortion from the 2025 government shutdown. The BLS uses rolling samples for rent data, and data collection was interrupted during last October's shutdown, meaning samples were not updated. When replenished in April, a year’s worth of rent increases were captured at once, making the monthly change nearly double the normal level.

Core CPI excluding food and energy rose 0.4% month-on-month and 2.8% year-on-year, with part of the increase stemming from the rent distortion mentioned above.

Bloomberg Economics Chief US Economist Anna Wong and economist Troy Durie noted: "Consumers are cutting other spending to cope with rising gasoline costs, and businesses lack the pricing power to pass on costs. There is a mild undercurrent in core CPI, which we think is the more important signal for CPI’s trend over the next six months."

The Fed’s discussion will mainly depend on whether commodity shipping via the Persian Gulf can normalize

As for tariffs, core goods prices ex-food and energy were flat in April month-on-month—with new car prices down being the main drag. Categories sensitive to tariffs like clothing and toys saw smaller increases than March, and used car prices were essentially flat. Economists have been watching if retailers have mostly passed on Trump tariff costs, but high oil prices could again push up goods prices later this year.

Timiraos' view on policy outlook is clear: This round of data is a clear signal—the rate cut expectations priced in for early 2026 cannot be realized within this year. In his view:

The outlook largely depends on whether fuel and various commodities shipped via the Persian Gulf can return to normal. If flows resume, inflation assessment becomes clear, as decision makers need not worry about energy price surges and commodity shortages triggering 'second-order effects'.

Conversely, if shipping remains disrupted, with policy interest rates unchanged, rising inflation will keep real rates (inflation-adjusted rates) lower. This means the Fed can achieve policy easing even without substantive action. If this happens, it will be hard for Fed decision makers to continue sidelining the rate hike topic in internal debates.

Currently, futures markets show very limited expectations for another rate cut in 2026, though some economists still predict a possible cut this year. The Fed's key inflation indicator—the Personal Consumption Expenditure (PCE) price index—handles housing weights differently from CPI. The Producer Price Index (PPI), to be released Wednesday, will supplement several categories including airfares, which feed directly into the late-month PCE data.

Wall Street: Rate cut expectations pushed further back

After CPI was released, the rate market quickly adjusted its expectations for the Fed's policy path.

Media quoted analysts saying traders increasingly believe the Fed may not cut rates at all this year, or, if they do, it will likely be pushed to later this year.

Some Wall Street firms are even revisiting whether rate hikes are needed.

Morgan Stanley strategists believe that although economic growth has not clearly deteriorated, if oil prices stay high and core services inflation remains strong, the Fed may have to keep rates higher for longer.

Some analysts say the Fed now faces a classic "dilemma": On one hand, high oil prices are eroding consumer power and dragging the economy; on the other, inflation's resurgence constrains the Fed's easing space.

Reuters Breakingviews column pointed out that this CPI data further shows the US economy has not truly shaken off the "post-pandemic high inflation inertia."
