Z102609 – SI Silver US-to-China Exports

Chinese industrial and retail silver pull from the US market drives silver demand; US-to-China silver-bullion export flow captures the pull with V-shape state-conditional edge where transition periods underperform.

SIGNAL OVERVIEW

China and the US are the two dominant silver economies: US produces bullion and refines it; China is the largest industrial and retail consumer. The flow of silver-bullion exports from US to China captures Chinese demand in real-time via trade data. US customs reports monthly exports under HS code 710691 (silver in bullion form). This signal reads the series, computes year-on-year z-score, and bounds through tanh. On May 17 2019 the composite reached its series maximum plus 1.000 during peak Chinese demand. On October 18 2022 the composite reached minus 1.000 during the zero-COVID industrial slowdown in China. Phase +1 China-pull-elevated has delivered plus 1.72 percent mean forward 60-day silver return; Phase -1 weak-pull plus 0.98 percent; Phase 0 transition minus 1.77 percent. Transition periods between regimes carry the weakest forward edge. Today the composite reads -0.990, in China Slack Mild territory.

LIVE CHART

Thirty-six years of GC over SI, Z-scored against the trailing five-year baseline, bounded by tanh.

The dark line in the top panel is the composite bounded between minus one and plus one. The pale red band at the top marks elevated-China-pull regime. The pale green band at the bottom marks weak-pull regime. The transition middle band is where Phase 0 underperforms. The bronze line in the middle panel is the trailing 252-day rolling Spearman information coefficient. The lower panel is COMEX SI continuous back-adjusted price on the right axis in cents per ounce.

TODAY’S PLAYBOOK READING

STATE

China Slack Mild

STATE AND HISTORY

China Slack Mild. The composite is reading sustained negative-Z territory as silver’s partial catch-up against gold through 2025-2026 brings the ratio down against a 5 year baseline that still anchors on the 2022-2024 compression peaks.

WHY THE SIGNAL IS HERE

The 1,260 day rolling baseline has not yet rolled off the 2022-2024 peak-compression window. As those peak-compression days drop out through 2027, the baseline will normalize downward and the Z-score will drift back toward zero even without further ratio changes.

POSTURE FOR THE WEEKS AHEAD

The signal is a fast-reacting Z-score framing with saturation sensitivity. Readers should pair with the 20 year percentile companion signal (which reads the current ratio as moderately above baseline on the longer historical view) and physical-market silver signals for conviction.

WHAT THE CHART SHOWS

Today the composite reads -0.990 placing the dot inside the China Slack Mild band. US customs HS710691 refreshes monthly.

Scroll inside the table for the full history. Forward 60-day COMEX SI is measured from each run’s start date; a reader cannot trade off a start-date they only identify in hindsight, so this is a transparency log, not an alpha claim. Asterisked (*) returns are partial. The run is less than 60 trading days old. The full 60-day comparable fills in as more data arrives.

What this measures

US silver-bullion exports to China via the HS710691 customs code track physical silver movement from US refiners and Comex vaults to Chinese industrial consumers and retail markets. The engine reads monthly flow data, computes year-on-year z-score, smooths, and bounds through tanh.

Why it matters

China is the largest silver consumer; US is a major bullion exporter. Direct US-to-China silver flow measures Chinese pull better than aggregate import data.

Phase +1 elevated China pull delivers above-baseline silver returns. Avoid transition Phase 0 which carries the weakest forward edge.

US-China trade policy shifts (tariffs, export controls, sanctions) can create artificial swings in reported flow unrelated to underlying demand.
