Cost-push inflation in China intensified in April, with oil and petrochemicals leading the rise in PPI

Overview

This report focuses on China’s April inflation data, and its core conclusion is that cost-push pressure has clearly strengthened. PPI rose 1.7% month-over-month, with oil and petrochemicals contributing about 1.5 percentage points; upstream prices were further supported by commodities such as coal and non-ferrous metals. In contrast, consumer-goods PPI remains weak, indicating that upstream cost transmission to downstream is not even, and downstream margins face compression.

Core views

The report believes that the April inflation improvement comes mainly from upstream commodity and energy prices, rather than broad end-demand recovery. Oil, petrochemicals, coal and non-ferrous metals together explain about 90% of the month-over-month PPI increase; AI and green transition-related demand supports some mid- and downstream segments, such as mobile consumer electronics, communication equipment and some appliances. Spillover to CPI remains relatively modest, with core CPI excluding gold rising to 0.8% year-on-year and service inflation rising in healthcare and travel. On policy, against a backdrop of improved headline inflation data and strong trade performance, the report expects policy to likely stay on the sidelines.

Analysis framework

The report identifies the source of price increases by decomposing PPI and CPI subcomponents, and compares changes in upstream commodities, non-commodity components, consumer goods, core CPI and service prices. The analysis focuses on the impact of oil, petrochemicals, coal, non-ferrous metals, AI and green transition demand on the price chain, while using last year’s low base to assess the future year-on-year path of PPI.

Methodology notes

• Macro inflation analysisPPI/CPI component decomposition

  Identify the source of inflationary pressure by examining changes in producer and consumer price components.

  The report breaks down the April month-over-month PPI increase into oil and petrochemicals, coal, non-ferrous metals and other components, and cross-checks cost transmission using changes in CPI, core CPI and service prices.

• Macro forecastBase-effect analysis

  Use lower month-over-month readings from the prior year to explain why future year-on-year readings may be mechanically lifted.

  The report points out that May and June last year had relatively low PPI month-over-month figures, so even if momentum does not further strengthen materially, year-on-year PPI may remain elevated and exceed 3% in the coming months.

• Commodity price assumptionsBrent oil scenario assumption

  Use the Brent oil price forecast as an important exogenous assumption for upward pressure on PPI.

  Morgan Stanley oil strategists still expect Brent at 110 USD per barrel in 2Q, which supports the report’s view that year-on-year PPI will continue to rise.

Asset mapping & comparison

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

• China macro inflation

  Core object of research

  Strengths

  Headline PPI and CPI readings improved, showing stronger inflation momentum than before.

  Weaknesses

  The improvement is mostly cost-driven, with insufficient evidence of broad demand recovery at the end market.

  Comparison

  PPI is rising faster than CPI, indicating more pronounced upstream price pressure.

  Risks

  If upstream costs cannot be passed through to the end market, corporate profit margins may continue to be squeezed.

• Oil and petrochemicals

  Main driver of rising PPI

  Strengths

  In April, they contributed about 1.5 percentage points to the 1.7% month-over-month PPI rise, with oil up 17.5% month-over-month.

  Weaknesses

  Highly dependent on global oil prices, so prices can reverse quickly.

  Comparison

  Compared with coal and non-ferrous metals, oil and petrochemicals are more concentrated and more pronounced in contribution.

  Risks

  If Brent is below the 110 USD/barrel assumption, the PPI increase may be weaker than expected.

• Coal

  Energy spillover driver

  Strengths

  Coal price resilience provides supplementary support to PPI.

  Weaknesses

  April month-over-month increase is lower than oil, so its driving strength is limited.

  Comparison

  Its impact is weaker than oil and petrochemicals but stronger than most downstream industries.

  Risks

  Demand or policy changes could affect coal price persistence.

• Non-ferrous metals

  Supply-constrained and green transition-related driver

  Strengths

  Supply constraints and green transition demand support prices.

  Weaknesses

  Price contribution is more dispersed than oil and is transmitted unevenly downstream.

  Comparison

  Compared with AI and green transition value chains, traditional downstream segments remain weaker.

  Risks

  Supply release or demand cooling could weaken price support.

• Consumer electronics and home appliances

  AI demand spillover beneficiaries

  Strengths

  Mobile phone and home-appliance inflation rose 1.6 and 0.2 percentage points respectively, indicating some demand support.

  Weaknesses

  Benefits are concentrated in AI-related and selected categories, while broad consumer demand remains relatively weak.

  Comparison

  Performance is better than most general consumer-goods PPI.

  Risks

  If AI demand spillover does not persist, price improvement may recede.

• Downstream consumer goods

  Recipient of cost pressure

  Strengths

  Some end-market categories may be structurally supported by demand.

  Weaknesses

  Consumer-goods PPI has been negative for a second consecutive month, with a clear drag from food.

  Comparison

  Significantly weaker than upstream commodities and energy components.

  Risks

  Margin compression, insufficient demand, and weak cost transmission may continue.

• Commodity PPI month-over-month2.9%Higher than March’s 2.1%, indicating upstream commodity prices remain strong.
• April CPI year-on-year1.2%Higher than March’s 1.0%, but still at a moderate level.
• Core CPI year-on-year excluding gold0.8%The main text says an increase of 0.2 percentage points from the prior month; there may be methodological differences from the table’s core definition.
• Mobile phone inflation change+1.6 percentage pointsThe report believes AI demand has spilled over into mobile consumer electronics.
• Home-appliance-related inflation change+0.2 percentage pointsIncludes related categories such as computers and tablets.
• Travel service inflation change+0.8 percentage pointsThe report suggests this may partly reflect oil-price-driven effects.
• Brent oil price assumptionUSD 110 per barrelMorgan Stanley oil strategists’ Q2 assumption.
• Future PPI year-on-year outlookPotentially above 3%Mainly based on low month-over-month PPI baselines in May and June last year.

Impact & implications

From an investment perspective, the report indicates that rising upstream energy and commodity prices improve headline inflation readings but may also squeeze manufacturing and consumer-goods margins downstream. If oil prices remain elevated, year-on-year PPI may continue to rise and affect company costs, the duration of policy patience, and market expectations for inflation repricing. Relatively benefiting areas include oil, petrochemicals, coal, non-ferrous metals, and value chains linked to AI and green transition demand; relatively pressured areas include downstream consumer goods and some manufacturing with weak cost-pass-through capability.

Risks

• Sustained high oil prices could further push up PPI and compress downstream margins.
• The PPI improvement is mainly cost-driven rather than from broad demand recovery, so macro recovery quality may be uneven.
• Consumer-goods PPI remains weak, indicating weak end demand and limited cost pass-through.
• AI and green transition support is concentrated in selected industries and does not represent broad downstream recovery.
• If policy continues to stay on the sidelines due to improved headline inflation readings, margin pressure may take longer to digest.
• Minor OCR misalignment or definition differences in the tables mean some detail data should be confirmed against the original report charts.

What to watch

• Whether May and June year-on-year PPI continues to rise and exceed 3% due to a low base.
• Whether Brent remains near or deviates from the 110 USD/barrel assumption for 2Q.
• Whether oil, petrochemicals, coal and non-ferrous metals continue to contribute to PPI rises.
• Whether consumer-goods PPI recovers from negative levels, especially food and durable-goods components.
• Whether AI and green transition-related demand can continue to support consumer electronics, communication equipment and home appliances.
• Whether core CPI, healthcare service inflation and travel service inflation spread further.
• Whether policy continues to stay on hold between improving inflation headlines and margin compression.
