The FX board is split today. USD/JPY touches 156.84, up 0.59 on the day, and USD/KRW 1384.74, up 0.32; the yen and won are sliding as carry funds keep rotating into the dollar. But USD/CNY moves the other way to 6.6984, with the yuan gaining 0.0313 and refusing to weaken alongside its Asian peers. For transshipment desks this divergence matters: when your buy and sell books are in different currencies, the margin gets torn open by the rate alone.

Unpack it. SNSUC's seven crude grades for transshipment — ESPO, Dubai, Oman, Urals, Basrah Light, Bonny Light, Lula — are mostly quoted and settled in dollars, so the margin naturally sits in the USD/bbl frame. When the yuan firms, the landed cost of the same Brent barrel in ¥/t drops, but the dollar spread you sell to the offshore counterparty does not move; net the transshipment margin in yuan terms is compressed. Conversely, buying fuel oil or bitumen from domestic refiners in yuan is a real cost saving as the currency appreciates.

So today's lesson is not "lock dollars because the dollar is strong." The practical move is to split the currency exposure: hedge the dollar receivable with an NDF or forward, let the yuan payable ride the appreciation, and only protect the net position after cross-currency netting. CIPS straight-through clearing pulls RMB cross-border settlement from T+1 toward near-real-time, giving the desk room to flatten intraday. The FX gap is closed by treating pricing, settlement and hedging as three separate problems, not by betting one direction.
