On May 26, the PBOC announced it would add a counter-cyclical adjustment factor to its model for the daily USDCNY midpoint fixing. The aim is to reduce excess yuan volatility and curb one-way bets.
Analysts note this risks reverting toward the pre-August 2015 exchange rate regime.
A less market-determined yuan fix changes the currency backdrop for China-linked feed demand and import costs, though the direct link to feed commodity prices is indirect.
After 42 past neutral policy events, Chinese Yuan (CNY per USD) moved a median -0.0% over 5 sessions (50% higher; middle half -0.3% to +0.4%), and -0.2% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
The PBOC's counter-cyclical factor added to the USDCNY fixing model lets authorities lean against dollar strength, which supports yuan appreciation (CNY per USD down).
