On October 10 the FX board showed USD/CNY 6.6929, EUR/CNY 7.4865, EUR/USD 1.1193, USD/JPY 158.26 and USD/KRW 1,341.2. The yuan and euro both firmed against the dollar while the yen and won sat near lows — a split that directly hits SNSUC's local-currency cost on re-export arrivals.

SNSUC opens letters of credit in dollars but settles with downstream refiners in yuan; a weaker yen and won make Japan- and Korea-routed logistics and insurance pricier in local terms. Each 1% FX move shifts the local-currency value of a 100,000-tonne crude parcel by several million yuan, so SNSUC locks the rate into the arrival model before opening the LC rather than betting on the delivery date.

For members, the terminal's value lies in placing the five exchange rates next to crude prices on one sheet, separating oil-price risk from FX risk. When Brent rises and the yen falls on the same day, the surface reads as a double squeeze; unpacked, it is two positions that can be hedged separately.
