The Main Tension
The one thing to know todayRisk level ExtremeConcentration and front-end structure
Zinc takes the lead as concentration and backwardation converge
The score is 81, up from 68; registered/on-warrant stock is down -18.7% over a month. Cash–3M is +201.0 $/t (4.92%), a 22-day high; the cumulative public OI proxy through M1 is about 21.8× on-warrant stock, with 11 trading days to M1. Cash holdings include a 90%+ holder. The 50–80% band is subject to LME lending guidance, which partially brakes an extreme premium: this is elevated delivery-structure risk, not an inevitable or unbounded squeeze.

Methodology & Data Notes
Squeeze-risk score (0–100, rule-based)
The score aggregates five structural dimensions — concentration, a cumulative public OI proxy through M1, momentum and spread confirmation among them — under fixed, auditable rules. Dimension definitions, weights and trigger levels are internal-edition content; the public edition shows risk levels and direction only.
LME Tom-Next lending rules
| Position* | Max tom-next lending premium |
|---|---|
| 50–79.99% | 0.5% of prior cash price |
| 80–89.99% | 0.25% of prior cash price |
| 90–100% | At level (no premium) |
* Warrants + Tom + Cash ÷ live warrants. Tightness without a ≥50% holder has no such cap on the spread.
LME Front Month Lending Rules (effective 17 Mar 2026)
| Cumulative Spot Futures Position / Total Available Stock | Maximum M1 lending premium |
|---|---|
| 50–79.99% | 3% of prior M1 official close |
| 80–89.99% | 1.5% |
| 90–100% | At level |
LME Notice 26/049. The official ratio needs member/client cumulative net positions and Total Available Stock, neither reproducible from public data. This report's all-market prompt OI through M1 divided by on-warrant stock is a conservative public proxy, not the official ratio or a breach test.
Data chain & lags
Reports are archived at 06:30 SGT. After the London 11:00 release window, the workflow allows a 30-minute buffer and refreshes at 18:30 SGT (19:30 in winter), retrying every 15 minutes through 20:30. Banding, Holdings, and OI each use and independently validate the Data Date printed on their source report; stocks/prices are T-1, while off-warrant stock is a T-3 voluntary disclosure and a floor estimate.
Data quality
This issue's sentinels: 0 missing OI rows backfilled from the prior snapshot (dashed in charts), 0 low-confidence banding rows flagged, 2 curve outliers excluded, 1 stock row(s) dropped on internal-consistency checks. A stock row that fails internal consistency (on-warrant + cancelled must equal total) is treated as an upstream OCR column shift and dropped in full for that date. Nothing unreliable is silently kept.
