Goldman Sachs: May PPI Rose to 3.9% Led by Energy; Core CPI Fell to 1.1%

Overview

This report is Goldman Sachs' quick commentary on China's May 2026 inflation data. The core conclusion is that headline CPI remained flat YoY at 1.2% in May, as rising energy prices were largely offset by falling food prices; core CPI excluding food and energy edged down to 1.1%, reflecting weak demand for services such as tourism. Meanwhile, PPI rose further to 3.9% YoY from 2.8% in April, primarily driven by upstream industries including chemicals, oil & gas, and coal, with the upstream sector contributing approximately 82% of the PPI YoY rebound.

Core views

CPI structure showed significant divergence. Headline CPI YoY remained at 1.2% in May, unchanged from April but below Goldman Sachs' forecast of 1.4% and market consensus of 1.3%. The seasonally adjusted annualized rate (SAAR) slowed to 1.0% from 2.4% in April. Food price YoY decline widened to -1.7% (vs. -1.6% in April), with pork prices down 16.1% YoY and fresh fruit prices down 2.2%, while only fresh vegetable prices saw a slight increase of 1.6%. Non-food CPI YoY edged up to 1.9% from 1.8%, entirely driven by energy—fuel cost YoY growth expanded to 21.1% from 17.4%, contributing all of the non-food CPI sequential increment. Core inflation and service prices weakened. Excluding food and energy, core CPI YoY fell to 1.1% from 1.2% in April, with a SAAR of -0.1%. The report attributes this primarily to softer tourism-related service prices, with transportation service inflation declining to 4.7% from 5.1%. This signal indicates that despite imported inflationary pressure from the energy side, the recovery of endogenous household consumption demand remains moderate. PPI accelerated higher and was highly concentrated upstream. May PPI YoY rose to 3.9% from 2.8% in April, in line with market expectations but slightly below Goldman Sachs' forecast of 4.0%. The SAAR declined to 9.7% from 22.4%, indicating some moderation in sequential pricing momentum though it remains relatively strong. Structurally, chemicals, oil & gas extraction, and coal contributed 0.3, 0.2, and 0.2 percentage points respectively to the 1.1pp PPI YoY increase. Overall, upstream industries accounted for approximately 82% of the PPI YoY rebound. Producer goods PPI YoY rose to 5.2% from 3.8%, while consumer goods PPI YoY remained at -0.8% (vs. -1.0% in April), indicating continued blockage in price transmission between upstream and downstream sectors.

Analysis framework

The report employs standard inflation component decomposition, breaking down CPI into food, non-food, and core dimensions, and segmenting PPI by supply chain position into upstream/downstream and producer/consumer goods. It further quantifies each industry's percentage point contribution to YoY changes. Through this structured attribution, the analysis identifies that the current PPI rebound is almost entirely driven by upstream energy and raw materials, while CPI exhibits a divergent pattern of "rising energy, falling food, and weak services," leading to the judgment that current inflation is predominantly supply-side cost-push rather than demand-pull.

Methodology notes

• Macroeconomic frameworkVolume-price decomposition

  Inflation Contribution Decomposition (Percentage Point Contribution Method)

  Decomposes CPI/PPI YoY changes into percentage point contributions from sub-components, e.g., calculating how many percentage points chemicals, oil & gas, and coal each contributed to PPI growth. This method helps readers distinguish whether inflation is concentrated in a few industries or broadly based, which is a key step in assessing inflation persistence and policy implications.

• Macroeconomic framework

  Core CPI as an Indicator of Domestic Demand Temperature

  Core CPI, which excludes volatile food and energy components, is generally considered a better gauge of endogenous household consumption demand. This report uses the decline in core CPI to infer weaker demand for services such as tourism, reflecting the application of this analytical convention.

  Analysis of PPI Upstream-Downstream Price Transmission Blockage

  Comparing trends in producer goods vs. consumer goods PPI helps assess whether upstream price increases can be passed through to terminal consumer products. In this report, producer goods PPI rose to 5.2% while consumer goods PPI remained negative, suggesting cost pressures have not yet been effectively transmitted to the consumption end, providing reference value for judging corporate profit distribution and monetary policy orientation.

Key data

• May CPI YoY+1.2%Flat vs. April; below GS forecast of +1.4% and market consensus of +1.3%
• May Core CPI YoY+1.1%Down from +1.2% in April, reflecting softer tourism service prices
• May Food CPI YoY-1.7%Decline widened from -1.6% in April; pork prices -16.1% YoY
• May Non-Food CPI YoY+1.9%Slight increase from +1.8% in April; dominated by fuel costs +21.1% YoY
• May PPI YoY+3.9%Significant increase from +2.8% in April; in line with market expectations
• Upstream Industry Contribution to PPI Rebound~82%Chemicals, oil & gas, and coal combined contributed 0.7pp of the 1.1pp PPI YoY increase

Impact & implications

The data in the report depicts a structurally divergent inflation landscape: price increases in upstream energy and raw material industries are significant but have not been effectively transmitted to downstream consumer goods and household services. This implies that the current PPI rise is more cost-push than demand-pull, potentially squeezing margins for midstream manufacturing enterprises; meanwhile, the decline in core CPI suggests the foundation for household consumption recovery remains fragile. For investors focused on China's macro cycle, monetary policy easing space may still exist under this divergent pattern, but vigilance is needed regarding potential erosion of mid-to-downstream profitability from sustained high upstream prices.
