U.S. core inflation rebounded moderately in July, with consumer electronics prices emerging as a new upside risk

Overview

The report tracks U.S. CPI for July 2026 and updates the core PCE forecast using CPI and PPI components related to PCE. Core CPI rebounded moderately after unusual weakness in June; services inflation was broadly in line with expectations, while goods inflation exceeded expectations due to higher consumer electronics prices. Even so, the net impact of CPI data on the core PCE forecast is limited, and Nomura still expects medium-term core inflation to decline gradually.

Core views

First, core CPI rose 0.215% m/m in July, mainly reflecting the fading of temporary drags in June, and does not imply a significant deterioration in the underlying services inflation trend. Second, core goods inflation unexpectedly accelerated, with prices of computers, smartphones, and audio-visual products rising notably, potentially reflecting the transmission of the AI investment boom to consumers through semiconductor prices. Third, the July core PCE m/m forecast was raised only slightly to 0.219%, while y/y growth is expected to fall to 3.26%, which can still be viewed as progress toward the 2% inflation target. Fourth, slower wage growth, negative residual seasonality in the second half, annual PCE revisions, and weaker tariff effects should support continued disinflation, so the report maintains its view that the Fed will not raise rates through end-2027.

Analysis framework

The report uses a bottom-up decomposition of inflation components, dividing core CPI into core goods, core services, and supercore services, and compares actual results with Nomura's forecasts. It then identifies CPI and PPI components that can be mapped to PCE and estimates their basis-point contributions to core PCE. The report also uses BEA input-output tables to identify consumer electronics categories sensitive to semiconductor prices, and assesses the future inflation path using wages, hotel industry prices, airline fuel costs, stock market performance, and historical seasonality.

Methodology notes

• Inflation component analysisBottom-up decomposition of core CPI

  Decomposing core inflation into goods, services, and supercore services components

  By comparing actual m/m increases in each component with forecasts, the report distinguishes temporary fluctuations, underlying inflation trends, and new price pressures from consumer electronics.

• Cross-indicator mappingCPI and PPI to PCE mapping

  Estimating the contribution of relevant components to core PCE based on PCE weights and data sources

  The report converts PCE-related CPI and PPI components into core PCE contributions, using this to fine-tune the July core PCE m/m forecast from 0.211% to 0.219%.

• Industry transmission analysisSemiconductor price sensitivity analysis

  Using BEA input-output relationships to identify the transmission of semiconductor price increases to consumer electronics inflation

  Information technology goods and audio-visual products are viewed as relatively sensitive to semiconductor prices; in July, they together contributed about 7 bp and 2 bp to core goods CPI and overall core CPI m/m, respectively.

• Time series analysisResidual seasonality and forward-looking indicator analysis

  Combining historical monthly patterns and leading indicators to assess future inflation

  The report uses negative residual seasonality in core PCE in the second half, as well as indicators such as wages, hotel prices, fuel costs, and stock market performance, to assess the subsequent direction of inflation.

Asset mapping & comparison

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

• U.S. Treasuries and U.S. dollar rates

  Moderate core PCE and the no-rate-hike view are broadly supportive of bond performance and reduce near-term rate-hike pricing.

  Strengths

  Inflation is expected to slow gradually, with July core PCE around 0.2% m/m, consistent with the view that progress is being made toward the 2% target.

  Weaknesses

  Core PCE y/y is still expected to be 3.26%, clearly above the Fed's target.

  Comparison

  Compared with June, July core CPI rebounded m/m, but core PCE y/y is expected to edge down from 3.29% to 3.26%.

  Risks

  If consumer electronics and semiconductor price pressures persist, they could heighten hawkish officials' concerns about reflation.

• U.S. equities

  Lower near-term rate-hike risk is supportive of valuations, but stock market gains could also temporarily lift PCE through portfolio management services prices.

  Strengths

  A macro scenario of stable interest rates is relatively favorable for risk assets.

  Weaknesses

  Strong stock market performance in the second quarter may cause July portfolio management prices to exceed forecasts.

  Comparison

  The report's base forecast only includes a 1.7% m/m increase in this PPI component, but there is an additional upside risk of about 3 to 4 bp to core PCE.

  Risks

  Higher-than-expected inflation could revive rate-hike expectations and compress equity valuations.

• Semiconductors

  The AI investment boom is boosting chip demand and may affect consumer electronics prices through cost pass-through.

  Strengths

  Strong demand reflects the expansion of AI-related investment, and prices of semiconductor-sensitive products have already risen notably.

  Weaknesses

  The base case expects semiconductor price pressure to gradually ease once supply catches up with demand.

  Comparison

  Semiconductor-sensitive components contributed about 7 bp to core goods CPI m/m in July, but still dragged on core CPI y/y.

  Risks

  If supply adjustment is slower than expected, price pressure may persist and trigger a more hawkish monetary policy response.

• Consumer electronics

  Computers, smartphones, and audio-visual equipment were the main sources of the unexpected upside in July core goods inflation.

  Strengths

  Higher end-market prices may reflect stronger demand and some ability to pass through costs.

  Weaknesses

  Price increases may suppress real demand and intensify policymakers' concerns about the inflationary effects of AI investment.

  Comparison

  Computers, peripherals, and smart home devices rose 3.5% m/m, smartphones rose 1.1%, and audio-visual products rose 1.2%.

  Risks

  Continued increases in semiconductor costs, declining demand elasticity, and a hawkish shift in monetary policy expectations.

• Expected contribution of PPI data to July core PCE11 bpPortfolio management and investment advisory services prices are expected to rise 1.7% m/m.
• Upside risk from PPI-related forecastsAbout 3 to 4 bpPortfolio management prices in July may show early-quarter volatility, and strong stock market performance in the second quarter could lift this component.
• Fed policy viewNo rate hikes through end-2027Moderate July core PCE is expected to reduce the likelihood of a near-term rate hike in September.

Impact & implications

The report's direct implication for U.S. rates assets is dovish: if core PCE grows moderately as forecast, the probability of near-term rate hikes should decline, and the Fed is more likely to keep rates unchanged. For the equity market, overall disinflation is favorable for the valuation environment, but AI capital expenditure may create a new inflation transmission channel through semiconductor supply-demand dynamics and consumer electronics prices, thereby limiting expectations for monetary policy easing. The consumer electronics and semiconductor industries benefit from expanding AI demand, but also face risks from rising costs, higher end-market prices, and a policy shift back toward hawkishness.

Risks

• The AI investment boom continues to push up semiconductor and consumer electronics prices, causing medium-term core inflation to exceed the base forecast.
• Portfolio management and investment advisory services prices may show a large seasonal fluctuation in July, potentially raising the core PCE forecast by about 3 to 4 bp.
• Travel-related components such as airfares are highly volatile and may cause monthly inflation data to deviate from trend.
• Tariff effects may fade more slowly than expected, delaying the decline in core goods inflation.
• Hawkish Fed officials may place more emphasis on consumer electronics price signals and reassess the need for rate hikes.
• The new PCE methodology for portfolio management and investment advisory services scheduled for introduction on September 30 may change the comparability of subsequent data.

What to watch

• The final July core PCE release and whether it is close to the 0.219% m/m forecast.
• Portfolio management and investment advisory services prices in July PPI, and the potential upside deviation of 3 to 4 bp.
• Whether prices of computers, smartphones, televisions, and audio equipment can continue to rise.
• Whether semiconductor supply catches up with AI-related demand in time, thereby easing cost pressure in consumer electronics.
• Whether lodging prices turn to moderate increases in August as expected in the report.
• The evolution of wage growth, rent inflation, and negative residual seasonality in core PCE in the second half.
• Fed officials' comments on inflation risks triggered by AI investment, and policy pricing for the September meeting.
• Data changes after the implementation of the new PCE portfolio management price methodology on September 30.
