Macro: This week is a "super payrolls week," September rate hike pricing at 64%–68%
(1) Aug 7 US July nonfarm payrolls is the main switch this week. After the Fed's "9-3 hold" on Jul 29, rate-futures implied probability of a September hike pulled back from nearly 100% before the meeting to 64%–68%, with 1.3 hikes for the full year. Markets expect about 80,000 new jobs in July and unemployment rate of 4.3%; if data is strong → hike probability back to 100% → US Treasury yields rise further, zero-coupon assets under pressure; if it extends the June 57,000 weakness → dovish repricing, tin prices surging accordingly.
(2) Aug 3 tonight's ISM manufacturing PMI (prior 53.8) kick off, with Aug 5 ADP and Aug 6 initial jobless claims as leading signals; same day, SpaceX's post-IPO first earnings report and AMD's after-market earnings. If AI chain sentiment diverges further, tin's "computing power solder alpha" could be swayed by tech stocks in the near term.
(3) First trading day after the US-Iran "cancellation of strikes" framework was finalized, Brent oil still around $91/bbl, the risk of secondary push from energy inflation remains, resonating with the Warsh "supply shock inflation" narrative—this is the medium-term backdrop where the rate hike shoe has yet to drop this year.
Fundamentals: Three new disturbances on the supply side in the first week of August
(1) On the ore supply side, additional tightening items, not just Wa State. Yinman Mining is expected to halt production for some time due to an accident—this is the new domestic mine output reduction in August;
(2) Smelting side: Yunnan's 40% tin concentrate TC remains at historical lows.
(3) Demand: Apple/Huawei new phone stockpiling in late August has not yet started; July solder operation rate recovered MoM but spot demand was average under high prices; AI servers + advanced packaging annual incremental volume about 12,000–15,000 mt, accounting for 3%–4% of global consumption, low weight but contributing almost all marginal growth, serving as the core amplifier of a "small commodity with high elasticity."
Spot Market
On Aug 1, SHFE tin 2609 closed at 427,110, with a spot-futures price spread of about 930 yuan/mt. SMM #1 tin spot closed around 426,000–428,000 yuan/mt on Aug 1, with tiered premiums for Yunzi/Yunxi brands continuing (small brand +500~+900, Yunzi +900~+1,200, Yunxi +1,200~+1,500).
On Aug 3, the morning session spot price is expected to open at 426,500–429,000 yuan/mt: after the night session surged to 428,200, if the 2609 contract stabilizes at 427,000 in the morning session, traders will hold back from selling and push up premiums; above 428,000, solder plants have very low willingness to fix prices, while 418,000–423,000 is the range where downstream buyers are willing to fix prices later—the high-level stagnation pattern of "futures hitting new highs, spot following higher but thin trading" continues.
