Pairing digital warehouse receipts with IoT tank-level gauges has pulled SNSUC's in-transit collateral mark-to-market from T+3 to T+0. The gauges report tank volume every 15 minutes within a ±0.3% error band, so valuation no longer waits for month-end inventory counts.

The mechanism is three layers: the receipt hash goes on-chain to make title tamper-evident, the gauge supplies a live physical anchor, and the bank uses both to cut the floating-value credit cycle from three days to half a day. The financeable ratio rises to 75%, well above the paper-receipt era.

For the entrepot trader, working capital arrives while the cargo is still at sea, before the bill of lading hits port. The risk sits in gauge drift, so we require tank gauges and weighbridges as dual cross-checks, and any deviation beyond 0.5% auto-freezes that credit line.

This turns in-transit assets into a usable position, provided the metering equipment holds its calibration certificate and clears the bank's due diligence.
