As of Sep 9, 2026, blockchain verification coverage for SNSUC digital warehouse receipts reached 92.7% (+1.4 ppt w/w), with average NPL rate for crude, fuel oil, and asphalt financing at 0.18% — 1.32 pts below industry average; amid price moves in fuel oil (¥3,895/t, +0.05%) and asphalt (¥4,903/t, -0.61%), on-chain operational traceability stood at 99.96%.

USD/CNY printed 6.7108, down 0.10%, with EUR/CNY easing in parallel — a sign of marginally looser offshore liquidity. For transit trade that buys in USD and settles in RMB, such a window of easing import cost typically lasts only a few sessions, so settlement and hedging should be brought forward accordingly.

SNSUC's traceability stack uses a browser-side SHA-256 fingerprint as the verification entry point: a buyer needs to trust no intermediary, recomputing hashes for the warehouse receipt, inspection report and bill-of-lading elements locally and comparing them with the on-chain anchor. Covering thirteen operating categories and seven crude re-export grades, it turns title verification from a paper relay into a single, independently recomputable check.
