U.S. inflation cooled unexpectedly in June, with the core PCE forecast revised down

Overview

This report tracks U.S. June CPI, PCE-related components, PPI-related inputs, inflation expectations, and subsequent monetary policy implications. The key conclusion is that June inflation data came in clearly below expectations, core CPI turned negative month-on-month, and this led Nomura to lower its core PCE forecast. The report argues that although some services price weakness may include one-off noise, slowing wage growth, residual seasonality, PCE annual revisions, and fading tariff effects collectively point to a gradual cooling of core PCE in the second half.

Core views

Nomura believes the June decline in core CPI should not be linearly extrapolated because volatile components such as auto insurance, hotel stays, air travel, and medical services materially weighed on the monthly reading. However, the weakening of supercore services inflation is consistent with slower wage growth, and core goods inflation has not risen meaningfully despite AI-related semiconductor shortages. The report expects June core PCE month-over-month at 0.168%, with year-over-year falling from 3.4% in May to 3.3%; under the current PCE methodology, year-end core PCE y/y could decline to 3.2%, and could further fall to 3.0% if the forthcoming methodology adjustment is included.

Analysis framework

The report applies CPI component decomposition, CPI-to-PCE weight mapping, PPI-linked PCE component forecasting, wage indicators to interpret services inflation, tariff-sensitive goods tracking, and residual seasonality analysis to assess June inflation prints and their implications for core PCE and the Fed policy path.

Methodology notes

• Inflation component decompositionCore CPI and supercore CPI decomposition

  Decompose monthly changes in core CPI by services, goods, and volatile components.

  The report attributes the unexpected June decline in core CPI to weakening service prices, especially supercore services, while noting that volatile items such as car insurance, hotels, airfares, and medical services may have amplified the short-term downturn.

• Inflation forecast bridgeCPI/PPI to core PCE forecast

  Use CPI and PPI components that flow into the PCE price index to estimate core PCE.

  The report revises the June core PCE month-over-month forecast to 0.168% based on June CPI-related components and estimates that PPI-linked components contributed about +7 bps to June core PCE.

• Policy implication analysisInflation path and Fed reaction function

  Use core PCE month-over-month and the medium-term inflation trend to assess rate-hike risk at the Fed.

  The report argues that core PCE month-over-month around 0.2% will be seen as progress toward the 2% target, lowering the probability of a rate hike around July or September and supporting a long period of no hikes.

• Structural price pressureTariff-sensitive goods and AI-related consumer electronics price tracking

  Assess tariff and semiconductor price transmission to core goods inflation.

  The report finds that more than half of tariff-sensitive CPI goods components fell in June, while some AI-related consumer electronics prices showed upward pressure but their weight is small, making the overall effect on core CPI limited.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• U.S. rates

  Lower core PCE reduces the near-term probability of rate hikes.

  Strengths

  The June core PCE forecast was revised down, and the month-over-month reading is near the Fed-acceptable progress range.

  Weaknesses

  Year-over-year core PCE remains above the 2% target, and three- and six-month annualized readings remain elevated.

  Comparison

  Compared with before the CPI release, the data more strongly support rates staying unchanged rather than additional hikes.

  Risks

  If subsequent PCE or wage data re-strengthen, the risk of rates moving higher again would increase.

• USD

  A dovish inflation interpretation may reduce rate-hike expectations as support for the dollar.

  Strengths

  Unexpectedly cooler inflation lowers expectations of policy tightening.

  Weaknesses

  The report does not provide a direct USD trading view, and exchange rates remain influenced by growth and global yield-differential factors.

  Comparison

  Relative to a high-inflation scenario, current data imply weaker support for the dollar from interest-rate differentials.

  Risks

  If markets focus more on U.S. growth resilience or if other central banks move dovish, the dollar could react differently.

• U.S. consumer electronics goods

  AI and semiconductor price increases could create localized component-level inflation pressure.

  Strengths

  Prices for certain video devices, computer software, and accessories rose clearly in June.

  Weaknesses

  Those components have a very small combined weight in core CPI, so the overall impact is limited.

  Comparison

  Fading tariff effects still more strongly restrain core goods inflation than AI-related price pressure.

  Risks

  If semiconductor prices continue rising and spread to higher-weight components, goods inflation could rise again.

Key data

• June core CPI m/m-0.017%Below Nomura's forecast of 0.215% and the market consensus forecast of 0.2%, and the first monthly decline since May 2020.
• June core PCE m/m forecast0.168%Revised down 10 bps from 0.271% in the pre-CPI forecast, equivalent to about 2.0% annualized.
• June core PCE y/y forecast3.3%Expected to decline slightly from 3.4% in May.
• Three-month core PCE annualized forecast3.0%Expected to decline from 3.5% previously.
• Six-month core PCE annualized forecast3.8%Expected to decline from 4.1% previously.
• Supercore CPI services m/m-0.203%After excluding energy and rent-related components, this reached the lowest level since May 2020.
• Core CPI goods m/m-0.1%In line with Nomura expectation; more than half of tariff-sensitive components declined in June.
• Year-end core PCE y/y forecast3.2%Based on current PCE methodology; could fall further to 3.0% if impending methodological changes are incorporated.
• Fed policy callNo hikes through end-2027The June cooling in inflation lowers the near-term probability of resuming hikes.

Impact & implications

The report's main market implication is that U.S. inflation pressure is easing at the margin, near-term hike risk is declining, and rate markets are more likely to price that the Fed staying on hold is justified by data. For goods inflation, weakening tariff impacts have offset some AI-related hardware price pressure; for services inflation, slower wage growth remains the key support for further disinflation.

Risks

• June services inflation weakness may be amplified by one-off noise, with partial rebound possible in subsequent months.
• A PCE methodological change could revise both historical and current core PCE readings, affecting trend interpretation.
• If AI-related semiconductor and consumer electronics price pressures spread, they could limit core goods inflation disinflation.
• If wage growth fails to continue slowing, the projected cooling path for services inflation may fall short of expectations.
• If tariff impacts re-strengthen or supply-chain tightness returns, core goods inflation could rise again.

What to watch

• Whether the official June core PCE release is close to the 0.168% month-over-month forecast.
• Whether prices for car insurance, medical services, hotel stays, and air travel rebound in July.
• Whether wage growth indicators continue to slow and feed through to supercore services inflation.
• Prices in PPI for portfolio management and investment advisory services, and the airfare component.
• The impact of the post-September 30 PCE methodology change on both current and historical core PCE readings.
• Signs of price spillover in tariff-sensitive goods and AI-related consumer electronics components.
