Asian FX split tonight. USD/JPY at 158.36 — the yen another 0.25% softer against the dollar — while USD/KRW at 1,329.4 means the won firmed 0.38% against the dollar. One weaker, one stronger, a different tune from last week when the yuan and won rose together.

On SNSUC's transfer book this split rewrites two legs directly. We quote in USD and settle the downstream in local currency. A stronger won makes the won leg cheaper — the same KRW payment converts back into fewer dollars — while a weaker yen makes the yen leg dearer: paying out costs more dollars. Tonight the CNY/KRW cross sits at 199.0 (one yuan buys about 199 won) and CNY/JPY near 23.7.

Two operational moves. First, where CIPS direct clearing is available, run the won and yuan legs straight through CIPS and drop the USD clearing step. Second, hedge the exposure with NDFs, the yen leg in particular — USD/JPY above 158 means every hundred-point swing is a fraction of a percent of cargo value. Do not leave all three legs on spot.

The transfer margin got kneaded by FX all week. The good part: Brent easing pulled the landed base down, partly offsetting the dearer yen leg. The bad part: a stronger won lowers the downstream landed cost settled in KRW, and customers will use that to push on price. Put the currency structure into the contract schedule rather than haggling only on the headline number.
