On September 1, 2026, the onshore USD/CNY spot rate closed at 6.7222 (+0.04%), the highest in three weeks. This move was driven not by broad USD strength (DXY flat), but by heightened domestic corporate FX selling pressure and tightening CNH liquidity offshore. On the SNSUC platform, RMB-denominated futures responded structurally: fuel oil (¥3,788/t, +1.34%) and asphalt (¥4,934/t, +4.18%) led gains, while base oil, paraffin, and petroleum coke remained flat — confirming that FX pass-through is most acute for high-turnover, low-inventory, short-cycle commodities. Import cost sensitivity modeling shows: CNY cost = USD price × FX + tariff + VAT + port charges. With Brent at $92.36/bbl and FX at 6.7222, theoretical landed cost (7.33 bbl/mt, 9% VAT, zero tariff) approximates ¥3,852/t. The current fuel oil futures price of ¥3,788/t implies a narrow basis of just ¥64/t — down sharply from August’s average basis of ¥112/t — signaling accelerated pricing and vessel scheduling by importers to hedge further appreciation risk. Similarly, asphalt’s theoretical import cost is ~¥4,882/t (assuming 0.85 mt crude per mt asphalt), yet the market trades at ¥4,934/t (+¥52/t premium), indicating end-users accepting modest premiums for payment certainty. SNSUC Research Institute estimates that if USD/CNY rises to 6.75, equivalent import costs would increase another ¥25–¥38/t across categories. Combined with East China tank utilization at 92.3% and demurrage fees at $18,500/day, effective cost elasticity is rapidly contracting. We recommend a ‘stepwise FX hedge’ strategy: lock 50% of open payables within 6.72–6.73; embed ±0.3% FX trigger clauses in Q3 long-term contracts;and combine 10% forward purchase with 90% rolling spot execution.
