Gold Alone Doesn't Lift All Prices: How Gold-Silver-Copper-Oil Rallies Cascade into Industrial Goods, PPI and CPI

Forum topic · 小凯 · 2026-11-01

Summary

This quantitative study examines how precious metal rallies transmit into industrial goods and consumer inflation, using 742 months of cross-cycle data (1965–2026) from BLS, World Bank, IMF, and market sources. Its central thesis: a gold-only rally typically coincides with industrial deflation; only when silver catches up—collapsing the gold/silver ratio (GSR)—does monetary liquidity cross into the real economy, igniting copper, aluminum, oil, and ultimately PPI and CPI. Cross-correlation analysis finds gold leads US CPI by roughly 18–22 months and silver leads copper and China's PPI by 1–5 months; crude oil is the strongest direct cost anchor for PPI (r≈0.89). Granger tests show silver—but not gold—significantly predicts copper, base metals, and metal-products PPI. In simultaneous regressions, gold and silver's direct coefficients on broad PPI vanish, leaving oil and copper dominant. Four historical bull cycles (1971–1980, 2001–2011, 2019–2022, 2023–2026) are reviewed, along with PPI-to-CPI pass-through rates across eras, micro-level earnings impacts on A-share photovoltaic silver-paste and copper-processing companies, and a four-checkpoint macro framework built around GSR regime shifts, transmission lags, capacity conditions, and substitution risk (copper-for-silver).

This post presents a 60-year quantitative investigation into how gold and silver rallies transmit into industrial commodities, PPI, and CPI, built with the Vibe-Trading research toolchain over a monthly panel spanning 1965–2026 (742 months), drawing on BLS, World Bank, IMF, Yahoo Finance, and Eastmoney data, plus A-share photovoltaic silver-paste and copper-processing earnings.

Key points

Gold-only rallies ≠ inflation. Gold's industrial demand is only ~7–10% of total demand. Statistically, gold "leading" industrial prices reflects the time gap between instant financial repricing and sticky real-economy transmission (6–18 months), not gold directly raising costs.
Silver is the bridge. Silver combines ~45% monetary and ~55% industrial properties (PV paste, contacts, EVs, AI connectors). A GSR collapse signals the switch from safe-haven to reflation trading and triggers preventive inventory building in industrial metals.

Transmission channels

1. Common macro factor (gold): falling real rates / fiat dilution reprice gold instantly; the same liquidity impulse reaches factories months later. 2. Cross-asset rotation (silver): extreme GSR (85–100+) pulls CTA/index money into silver, signaling reflation and sparking copper/aluminum rallies. 3. Physical BOM pass-through (silver locally, copper/oil globally): silver directly hits PV paste and low-voltage equipment costs; beyond thresholds it triggers copper-for-silver substitution, converting precious-metal pressure into copper demand.

Quantitative evidence (1968–2026)

Lead-lag (CCF): gold leads silver ~0m (r=0.78), copper ~2m, base metals ~4m, US metals PPI ~7m, broad US PPI ~11m, total CPI ~18m (r=0.52). Silver leads copper (r=0.53–0.59), US metals PPI ~5m (r=0.54), China PPI ~5m (r=0.48). Crude oil leads both US and China PPI by ~1 month with r≈0.83–0.89 — the strongest physical cost anchor.
Granger causality (log-differenced, HAC-robust): gold → silver significant at 12m lag; silver → copper, base metals, oil, US metals PPI significant; gold → copper/industrial PPI not significant; copper/oil → US PPI overwhelming (p<0.0001); PPI → CPI significant at 3–12m.
Horse-race regressions (Newey-West): gold +10% YoY historically predicts +1.14pp US PPI after 9 months and +0.56pp CPI after 15 months; silver +10% predicts +0.53pp China PPI after 3 months. But in simultaneous equations, gold and silver's direct coefficients on broad PPI collapse to zero (p≈0.95–0.99) while oil dominates (β=0.094, t=9.83). For copper price prediction, silver wins (β=0.375, p=0.024), gold drops out.
GSR regime split (1991–2026, 430 months): when GSR YoY < −15% (silver squeeze/reflation regime, 65 months): gold +19.5%, silver +62.4%, copper +33.8%, oil +17.6%, US PPI +5.76%, China PPI +5.25% after 3 months. When GSR YoY > +15% (lone-gold deflation regime, 66 months): copper −14.4%, oil −7.4%, China PPI −2.53%.

PPI→CPI pass-through across eras

| Era | US PPI → headline CPI (3m β) | US PPI → core CPI (6m β) | Verdict | |---|---|---|---| | 1970–1984 stagflation | 0.44 | 0.38 | Full high-pressure pass-through | | 1985–2000 Great Moderation | 0.25 | weakened | Anchored expectations halve transmission | | 2001–2019 globalization | 0.14 | 0.005 (decoupled) | Supply chains act as inflation sponge | | 2020–2026 restructuring | 0.20 | 0.12 (revived) | US core transmission revives; China's halves |

Four historical gold-silver cycles

1. 1971–1980: gold broke from $35 a year before copper doubled and oil quintupled; US CPI peaked at +14.8% in March 1980. 2. 2001–2011 QE supercycle: silver +918% crushed GSR to 35.3; global manufacturing absorbed costs so core CPI never exceeded 2.93%. 3. 2019–2022 pandemic QE: textbook 22-month relay — gold top (Aug 2020) → GSR 111.9→66.1 → copper/oil surge → China PPI +13.5% (Oct 2021), US PPI +24.7% → US CPI +9.06% (June 2022), exactly 22 months after gold. 4. 2023–2026: gold-only phase (GSR 101.2) matched China PPI at −3.6%; silver surge to $92.68/oz (Feb 2026, +323%) crushed GSR to 54.2, then copper ($6.59/lb) and oil (>$105/bbl) pushed China PPI from −0.9% to +5.0% and US CPI to 3.7–4.2%, while China CPI stayed at +0.9% — a +4.1pp scissors spread.

Micro-level earnings anatomy (2024 → 2025 annual reports)

Silver-paste makers (Jet Materials 688503.SH, DK Electronic 300842.SZ): revenue +17% but gross margins compressed, operating cash flow deeply negative (−3.07bn RMB for one) as silver must be prepaid while downstream stretches payables; hedge positions produced losses in the squeeze.
PV module leader (LONGi 601012.SH): transmission blocked by end-market overcapacity — gross margin collapsed from 7.44% to 0.81%, forcing industry-wide copper-for-silver substitution.
Copper processor (Jintian 601609.SH): full pass-through of 97.5% raw-material cost; net profit +56.2% with stable cash flow.

Practical four-gate macro compass

1. Check GSR first: GSR > 85 and rising >15% YoY = deflation-risk lone-gold rally (avoid industrial metals); silver breakout with GSR YoY < −15% = reflation starting gun. 2. Respect the lags: gold (t=0) → silver/GSR collapse (0–3m) → copper/base metals (1–3m) → oil and PPI peak (silver +4–5m) → CPI peak (gold +18–22m). 3. Read capacity conditions: deficit-spending, tight-services economies revive core CPI; overcapacity, deleveraging economies (China now) show wide PPI-CPI scissors — favor upstream miners, avoid squeezed mid/downstream processors. 4. Watch substitution extremes: extreme silver/copper ratios accelerate irreversible copper-for-silver adoption, capping silver's industrial demand slope while adding structural copper demand.
