Aug Concentration: Growth Top-1 Still ~32% / Asia Trade 71% — CPI Cools, Share Architecture Flat
August 202608 concentration lens on growth, trade and prices: China remains ~32% of world PPP growth (top-3 ~55%); Asia still owns 71% of merchandise trade-volume gains; PPP stock top-3 ~42% and export top-3 ~29% stay carried; US CPI 3.4% YoY (−0.1 pp) and PCE 3.7% cool while elevated-CPI GDP share holds ~38% and CPB June / GDP second estimate stay pending.

Our Q3 concentration lens answered the hard-data stress question: China still ~32% of world PPP growth on the carried base (only ~29% under a Q2 sensitivity), Asia still 71% of merchandise trade-volume gains, PPP stock top-3 ~42%, goods-export top-3 ~29%. The August CPI/PCE vintage then refreshed price levels — US CPI 3.4% YoY (−0.1 pp vs June), PCE 3.7% YoY (−0.4 pp vs May), euro-area HICP 2.9% — while flagging two still-pending flow meters (CPB June WTM due 25 Aug, BEA Q2 second estimate 26 Aug). This August concentration cut asks the desk question next: did those price prints rewrite the top-of-distribution shares, or only refresh the meters that sit beside a still-sticky architecture?
The interactive dashboard above is built as an August concentration lens. Toggle Scoreboard, Prices, Growth ladder, and Trade + pending. Use Growth vintage to flip the carried 2025 base against the Q2 sensitivity, and on Prices switch Cooling path versus YoY vs SAAR. The punchline is deliberately flat on shares and sharp on process. Top-1 growth contribution remains ~32% (China) and top-3 ~55%. Asia’s trade-growth share stays 71%. PPP stock and export-value ladders stay carried. What August adds is a disclosed cooling path, a YoY-vs-SAAR dual meter, and explicit pending flags so desks do not confuse a quiet share board with a finished data month.
The headline ladder: Q3 vs August restatement
| Lens | Q3 concentration | Aug print | Δ |
|---|---|---|---|
| Growth contribution Top-1 (China) | ~32% | ~32% base | 0 pp (carried) |
| Growth Top-1 Q2 sensitivity | ~29% | ~29% | 0 pp (held pending GDP 2nd) |
| Growth Top-3 (CN·IN·US) | ~55% / ~52% sens. | same | 0 pp |
| PPP GDP stock Top-3 | ~42% | ~42% | 0 pp |
| Merch trade-volume growth Top-1 (Asia) | 71% | 71% | 0 pp (CPB June pending) |
| Goods export value Top-3 | ~29% | ~29% | 0 pp |
| US CPI YoY | 3.4% | 3.4% (−0.1 pp vs Jun) | levels cool; share band unchanged |
| Elevated-CPI GDP share | ~38% | ~38% | 0 pp (threshold still ~3.4%) |
Read the table as a stability-plus-pending scoreboard. August did not re-rank the pie. It cooled several US price YoY meters, left the elevated-CPI burden perimeter at ~38%, and left two flow meters that could restate growth or trade sensitivity still blank on the calendar.
Scoreboard: carried architecture, August process flags
Open Scoreboard. The Q3 → Aug restatement panel keeps PPP stock, base growth contribution, trade-growth, export value, and elevated-CPI GDP share flat. US CPI and PCE YoY sit at the same July/June prints the August vintage already disclosed — the path cooling (−0.1 / −0.4 pp versus the prior month) is the new desk receipt, not a new Top-1 share.
The Top-1 vs Top-3 scatter still puts trade-growth (Asia 71% / 97%) in the extreme corner, growth contribution (32% / 55%) steeper than PPP stock (19% / 42%), and export value (14% / 29%) milder. The elevated-CPI GDP point (~15% US weight / ~38% elevated band) sits as a burden perimeter, not an additive market-share portfolio.
That is the first August hinge. Price cooling and share concentration are different objects. A −0.1 pp CPI print does not move China’s ~19% PPP stock weight. A pending CPB June MoM does not automatically re-rank Asia’s 71% of 2025 merchandise volume-growth contribution. Desks that treat “CPI cooled” as “concentration eased” are reading the wrong column.
Prices: cooling path, dual meter, unchanged geometry
Toggle Prices. The CPI × growth scatter still puts China at ~0.2% CPI beside ~5% GDP growth and the thickest growth contribution. The United States remains the large elevated-CPI weight (~15% of world PPP) at 3.4% July CPI and 3.7% June PCE against a 5.1% Q2 PCE SAAR. Euro-area HICP sits at 2.9% (+0.1 pp vs June). Roughly 38% of world PPP GDP in this cross-section still sits in economies with CPI at or above ~3.4%.
Switch the price panel to Cooling path. US CPI, PCE, and core PCE all print cooler than the prior month; EA HICP edges hotter; China CPI is unchanged near zero. Flip to YoY vs SAAR. The US PCE YoY–SAAR spread remains about +1.4 pp, and July CPI still sits −0.2 pp under the IMF’s 3.6% US CPI 2026 path. That dual meter is the August contribution relative to the Q3 concentration companion: not a new share ladder, but a clearer receipt that unit choice still dominates soft-landing arguments inside the same concentration geometry.
Pair this with the August monthly vintage. That post owns the level tape. This lens owns the distribution question: the growth leader is still not the price leader, and a cooler US YoY does not shrink the elevated-CPI GDP band while the US stays at 3.4%.
Growth contribution: base sticky, Q2 sensitivity held
Switch to Growth ladder. On the carried 2025 base, China is ~31.8% of world PPP growth, India ~14.6%, the United States ~9.1% — top-3 ~55%. Flip Growth vintage to Q2 sensitivity. China scales toward the 4.3% YoY hard print, the US toward 1.5% SAAR, and top-1 eases to ~29% / top-3 ~52%. August does not invent a new sensitivity — it holds the Q3 restatement because the BEA Q2 second estimate is still pending (26 Aug).
That is the second hinge. Pending revisions can restate contribution shares; they cannot yet be treated as if they already did. A softer second estimate would clip the US rung further without touching China’s PPP stock weight. A firmer revision would thicken the US contribution without democratising the tip. Either way, China would still clear roughly three times the US contribution on the base ladder. Soft-landing narratives that need China’s world-growth share below ~20% still fail the same concentration test the prior concentration print posed.
Trade and pending: Asia’s 71% holds while June is blank
Open Trade + pending. The WTO March 2026 regional decomposition of 2025 merchandise volume growth still puts Asia at 3.2 pp / 71%, Europe ~15%, North America ~11%, and the rest of the world ~4%. Top-3 regional share remains ~97%. The donut is carried because there is no newer GTOS vintage that re-ranks 2025 contribution shares.
The CPB line now shows March −2.1%, April +0.7%, May +1.0% MoM, and an explicit June pending marker. Cumulative Mar–May is still only about −0.4% below February. June (due 25 Aug) can confirm or fade that rebound — it remains a flow overlay, not a country or regional concentration census. Export-value shares stay at China ~14%, US ~8%, Germany ~7% — top-3 ~29% of ~$26.3T merchandise exports.
The third hinge is process discipline. A blank June cell is not a quieter Asia share. Treating “no new MoM” as “trade concentration eased” confuses calendar silence with distribution change. The pending-meter cards exist so the scoreboard’s flat Top-1s are read next to what August has not yet disclosed.
Who is exposed — and what would change the story
Exposed: desks that translate US CPI −0.1 pp into a thinner elevated-CPI GDP band while the US remains at 3.4%; growth factor models that treat the Q2 sensitivity as already revised by a second estimate that has not printed; trade narratives that treat May’s rebound as a finished regional re-decomposition before CPB June; soft-landing calls that quote cooler YoY without the 5.1% PCE SAAR still sitting in the dual meter; inflation debates that still imply the growth leader is the price leader.
Relative winners under current rules: Asian intermediate-goods and AI-goods corridors that still sit inside the 71% regional volume-growth share; India’s second-place growth contribution even under the Q2 sensitivity; US demand weight that still anchors PPP stock (~15%) while contribution ranks third; exporters diversified across the residual half of the $26T goods perimeter; desks that keep the August vintage and this share map in separate columns instead of averaging them into one “global cooling = less concentration” slogan.
What would change the story: a sustained WEO restatement that puts China’s share of world PPP growth below ~20%; Asian merchandise volume-growth contribution falling below ~50% of a new GTOS vintage; export-value top-3 climbing above ~40%; China CPI re-accelerating toward the world average while keeping its growth weight; a multi-month CPB freefall that forces a regional re-decomposition of who drives volume; US CPI falling clearly below the elevated threshold in a way that shrinks the ~38% elevated-GDP band. None of those clear this August window. The architecture is sticky; two flow meters are still pending.
Caveats and methodology
- PPP stock and base growth-contribution shares are carried from the prior/Q3 concentration prints (IMF WEO April 2026 PPP weights × country growth). No new period census.
- Q2 growth sensitivity is illustrative and held, scaling China toward 4.3% YoY and the US toward 1.5% SAAR advance. It is not a reconstructed WEO weight table; the 26 Aug second estimate may restate the US rung.
- Merchandise trade-growth shares follow WTO GTOS March 2026 (Asia 71% / 3.2 pp disclosed). CPB MoM through May is a flow overlay only; June is pending (25 Aug).
- Export value shares use ~$26.3T world merchandise exports (2025); re-export hubs inflate value versus domestic origin. Services (~$9.6T) excluded.
- Price ladder mixes disclosed BLS July CPI, BEA June PCE, and Eurostat July HICP with theme China CPI; “elevated-CPI GDP share” (~38%) is a burden perimeter, not an additive market share.
- YoY versus SAAR / IMF dual meters mix units on purposedirectional context for the US price weight, not like-for-like gaps.
- Euro-area growth contribution is an aggregate, not a single sovereign.
- Oil near ~$89/bbl in the July Update remains the energy backdrop for elevated YoY components; it is not re-estimated here.
The shareable takeaway
In the August 2026 concentration vintage, growth Top-1 is still ~32% China on the carried base — and only ~29% under the held Q2 sensitivity. Asia still owns 71% of merchandise trade-volume growth. PPP stock top-3 stays ~42%; goods-export top-3 stays ~29%. US CPI 3.4% and PCE 3.7% cool on a month-to-month path without shrinking the ~38% elevated-CPI GDP band, while CPB June and the BEA Q2 second estimate remain pending. August refreshed price meters and process flags. The top of the distribution held.
