〔Day Digest〕Copper Hits $14,273 Record Before Easing to $14,257 on Bessent's TGA Buyback Pledge and Expanded Iran Sanctions; Lithium's 158,860-Yuan Surge Fades to a 5% Drop - Warsh's Jackson Hole Script Decides the Next Leg

0. Daily Arc

A copper record, a lithium reversal, and a Bessent-anchored macro tape. LME 3M copper closed at a record $14,273/tonne before easing 0.1% to $14,257.9/tonne as the dollar stabilized, with aluminum -0.4% and nickel -0.5% ^[1]. Lithium pushed to 158,860 yuan/tonne (+1.6%) overnight on 5,701-lot lengthening, then gave back more than 5% intraday by the close ^[2][3]. Soft-dollar positioning and a near-$1 trillion TGA-financed buyback pledge held the bid under base metals ^[4][5]. What decides the next leg is Fed Chair Warsh's Jackson Hole speech Friday, with LME copper inventory flow and the Jiangxi Yifeng lithium EIA as falsifiers ^[6][2][1].

1. Copper: Record Print, Soft Pullback

• **[NEW] LME record, soft close:** 3M closed at $14,273/tonne after an intraday low of $14,149/tonne, last at $14,257.9/tonne (-0.1%); aluminum -0.4%, nickel -0.5% ^[1].

• **[ONGOING] Funds:** August saw 100+ billion yuan flow into non-ferrous ETFs; 3 new non-ferrous funds established, 3 more issuing, more in the pipeline ^[13].
• **[NEW] Weekly framing:** battery-grade spot 160,500 yuan/tonne (+5.5% w/w); LFP runs near full utilization, with August-September battery output exceeding LFP output - a tight-balance narrative ^[14].

• **[ONGOING] Rubber:** oscillating stronger ^[19].

4. Macro Tether

• **[NEW] Bessent buyback:** next Treasury buyback operation on Sept 9; considering a near-$1 trillion drawdown from the Treasury General Account (TGA, currently ~$950 billion) to finance the program; officials did not disclose final scale or timing ^[6][4].
• **[NEW] Iran sanctions expanded:** secondary sanctions on any country with Iran commercial ties; any entity laundering for Iran removed from the dollar system; Trump warned of "devastating economic action" and "largest-ever economic isolation" ^{[6][20][4][21]}.
• **[NEW] Canada:** Trump announced a 50% tariff on Canadian autos, parts, and steel from next year after US-Canada trade talks collapsed ^[6].
• **[NEW] BOJ:** former decision-maker said the "in-between" central bank may hike in September ^[20].
• **[ONGOING] Dollar:** stabilized after last week's Treasury-market intervention faded; Bessent did not detail a debt-management reform plan, cooling the soft-dollar trade ^[1].
• **[NEW] Funds:** 100+ billion yuan flowed into non-ferrous ETFs in August ^[13].

5. What Would Falsify

• **Jackson Hole script:** Fed Chair Warsh's Friday speech is the next hinge; a hawkish surprise would re-anchor the dollar, undoing the soft-dollar bid under copper and zinc ^[1].
• **LME copper inventory flow:** the current +1,675-tonne build is relieving the squeeze-risk premium; a sustained draw would re-tighten, a sustained build would cap the upside ^[6].
• **Lithium supply from Yifeng:** the EIA publication for the Jiangxi Zhenkouli-Fengxin Jianxiawo mine is in public consultation; approval timing is the marginal new-supply test against the tight-balance narrative ^[2].
• **Source quality control:** the "near-$1 trillion TGA" framing is a single Chinese-broker relay of US Treasury press and the sizing remains unconfirmed; the intraday lithium drop is corroborated across Mysteel, Cailianshe, and GFEX warrants, but the price-reversal mechanism (long liquidation vs spot offer) is not specified ^{[6][3][10][4]}.
