The tightest constraint in arbitrage is term mismatch: title has already transferred, but downstream payment runs 30–60 days while upstream often demands settlement before shipment. The gap was historically filled by bank receipt pledges, yet a paper receipt—from authentication and title confirmation to disbursement—averaged three business days.

Digital receipts compress that chain. Goods generate a SHA-256-fingerprinted electronic receipt on warehouse-in; the fingerprint can be recomputed independently in the browser without a round trip to a central server. Bank risk teams call the notarization directly to verify title, skipping forgery checks and manual confirmation, pulling funding from T+3 to T+0.

Run the numbers. On a $100m arbitrage credit line at 30-day terms and 70% pledge ratio, the three-day disbursement lag traditionally adds about 3/30—or 10%—to effective capital tie-up. At T+0 those three days return to usable balance, freeing roughly ¥67m and lifting turnover from about 9x to just over 10x.

For SNSUC this means one credit line can turn one more cargo. In months when the seven crude grades for arbitrage (ESPO, Dubai, Oman, Urals, Basrah Light, Bonny Light, Lula) arrive in clusters, T+0 funding turns a capital bottleneck into a pipeline.
