NIGHTLY INTELLIGENCE BRIEF

〔Overnight Brief〕Warsh's Jackson Hole Reset Pushes September Hike Odds to ~60% as China Supply Squeeze Holds — SHFE Copper -17.1 kt, Aluminum 98.03%, Lead Smelter Maintenance Widens

Fed Chair Warsh at Jackson Hole reaffirmed the 2% PCE target and warned the Fed 'still has work to do' if disinflation stalls, pushing CME-implied September hike odds from ~35% to near 60% and lifting the dollar and short-end US yields [1][2]. July PCE printed +3.7% y/y, +0.2% m/m, slightly above expectations [2]. Yet China-side physicals are tightening: SHFE copper stocks fell 17.1 kt to 72.4 kt, aluminum operating rate held at 98.03%, lead smelter maintenance widened to drop primary lead operating rate 1.9pp to 63.81%, and Jiangxi's Jianxiawo lithium project had its EIA acceptance notice withdrawn [4][1][5][6][7]. Zinc concentrate TC fell another 300 yuan to -1,850 yuan/metal ton, while LME (0-3) backwardation deepened to $231.75/ton [11]. The overnight session pits dollar strength against the supply squeeze — the falsifiable test is the September demand landing.

0. Weekly Arc

The macro tailwind flipped hawkish on Friday as Fed Chair Warsh at Jackson Hole reaffirmed the 2% PCE target and warned financial conditions are not meaningfully restrictive, pushing CME-implied September hike odds from ~35% to near 60% and lifting the dollar and short-end US yields [1][2]. Against that headwind, China-side physicals are tightening: SHFE copper stocks fell 17.1 kt to 72.4 kt, aluminum operating rate holds at 98.03% with domestic alumina at record-high capacity, lead smelter maintenance widened to push primary lead operating rate down 1.9pp to 63.81%, and Jiangxi's Jianxiawo lithium project had its EIA acceptance notice withdrawn [3][4][1][5][6][7]. The overnight session sits on a knife-edge: macro demand pressure vs physical tightness.

1. Macro — Warsh Rewrites the Path

  • **[ESCALATED] Fed Chair Warsh, Jackson Hole:** restated the 2% PCE target will not soften, argued current financial conditions are not meaningfully restrictive, and warned the Fed 'still has work to do' if disinflation stalls [1][2]. The Huatai read: he is dialing back forward guidance and pointing to AI's medium-term productivity upside [1].
  • **[NEW] July PCE:** +3.7% y/y, +0.2% m/m, slightly above market expectations, ending hopes of a clean disinflation leg [2].
  • **[NEW] Rate path repricing:** September hike probability rose from ~35% to ~40% on the data, then to near 60% post-Warsh per CME FedWatch [2]. Dollar and short-end US yields rose [1][2].

2. Copper & Aluminum — Physical Tightness vs Macro Drag

  • **[NEW] Copper global visible inventories turned lower again:** LME -6.0 kt to 234.3 kt, SHFE -17.1 kt to 72.4 kt, domestic social -4.7 kt to 109.5 kt; Comex continued to rise +10.9 thousand short tons to 753.6 thousand short tons, Shanghai bonded +1.8 kt to 38.5 kt [8][1]. The bonded and Comex buckets are bucking the drawdown trend.
  • **[NEW] Copper spot tightness:** SMM 1# electrolytic copper ran RMB 107,965-109,595/ton on the week; SMM premium/discount stayed elevated at RMB 210-535/ton under warehouse-squeeze dynamics [1][9].
  • **[NEW] Aluminum at 98.03% operating rate:** as of Aug 28, LME aluminum $2,622.0/ton, SHFE main RMB 23,920/ton, built capacity 45.77 million tons/yr, operating capacity 45.48 million tons/yr [7]. East China spot premium -10 yuan/ton, Central Plains -120, Foshan +200 [7].
  • **[ONGOING] Bauxite squeeze persists:** Shanxi 58/5-grade ore delivered tax-included price 628 yuan/ton, Henan 58/5 at 610 yuan/ton, with multi-province mine safety/environmental halts keeping ore supply tight; domestic alumina operating capacity is near historical high [3].
  • **[ONGOING] Demand mix is split:** aluminum billet weekly output 349.7 kt (-3.2 kt w/w), aluminum plate/strip/foil 385.9 kt (-1.2 kt), aluminum cable leaders operating rate 63.00% (+0.60pp), aluminum profile 50.60% (-0.20pp) [7].
  • **[ONGOING] The aluminum framing:** Huatai frames the market as 'short-term shortage vs expected surplus' — operating rate near full and ore tight today, but forward surplus expectations cap upside [7].

3. Lead, Lithium, Zinc — Supply Squeeze Continues

  • **[ESCALATED] Lead — smelter maintenance widens:** domestic primary lead comprehensive operating rate fell 1.9pp to 63.81% as Hunan, Henan, Yunnan, Inner Mongolia smelters ran routine or fault maintenance; five-region social lead ingot inventory drew -6.4 kt to 69.3 kt [6]. Pb50 domestic concentrate TC flat at 150 yuan/metal ton, import TC flat at -170 USD/dry ton [6].
  • **[ESCALATED] Lithium — Jianxiawo project setback:** Yichun Ecological Environment Bureau on Aug 26 said the Jianxiawo lithium mine EIA report had its acceptance notice withdrawn during the public notice period, after public concerns over the website used in the prior notice; Jiangxi supply disrupted [4][5].
  • **[ONGOING] Lithium carbonate tape:** 2701 contract opened RMB 161,500/ton, closed RMB 159,600/ton, +0.58% w/w, range RMB 148,320-162,500/ton; weekly total output 23,808 tons (up from 23,007); spot inventory 61,632 tons (-4,745) [5][10]. Demand: LFP +2.74% w/w, ternary -1.97%, lithium cobalt oxide -4.22%, lithium manganate +3.54%, LiPF6 +9.46% [5]. Tight-balance narrative continues.
  • **[NEW] Zinc — TC slide continues:** SHFE main closed RMB 26,485/ton (+0.08%), LME $3,879.5/ton, domestic SMM zinc concentrate TC -1,850 yuan/metal ton (-300 w/w), import TC -123.25 USD/dry ton (-5.75), import P/L -2,710.79 yuan/ton; LME (0-3) backwardation deepened to $231.75/ton (+32.80) [11]. Galvanizing operating rate 51.63% (-1.63pp), die-cast zinc alloy 46.77% (-2.69pp), zinc oxide 53.25% (+0.92pp) [11].

4. Nickel & What Falsifies

  • **[ESCALATED] Nickel — macro center falls:** SHFE nickel main traded RMB 129,000-131,000/ton, -0.34% w/w; SMM 1# electrolytic nickel average RMB 129,910/ton (+620 w/w); Jinchuan premium widened then narrowed to ~1,400 yuan/ton; mainstream domestic electro-nickel premium fell to the RMB -200 to -400/ton range [12][2]. The Huatai view: Warsh's hawkish reset, Middle East de-escalation, and looser Indonesia supply expectations have shifted the center lower [2].
  • **[ONGOING] Contradiction print:** the zinc TC slide signals raw-material tightness, and LME (0-3) backwardation deepening also signals spot tightness — yet galvanizing and die-cast operating rates are weakening on the demand side [11]. Both stories are live; the trade-off between ore tightness and downstream demand softness is unresolved.
  • **[ONGOING] What would falsify:** (1) a softer-than-expected September demand landing that breaks the physical-tightness narrative; (2) a clearer disinflation print that unwinds the Warsh-hawkish macro reset [1][5][2][9].
  • **[ONGOING] Source quality control:** [9] and [13] are the same Huatai English copper weekly with a typo difference — treat as one source. [5] and [10] are the same Huatai lithium weekly in Chinese and English — treat as one source. The bauxite-tight, Jianxiawo, and aluminum supply claims rest on single weekly notes [3][4][7]; the macro reset is corroborated by [1] and [2] (two-source); the LME/SHFE copper inventory draw numbers are also two-source via [8] and [1].
