The onshore yuan weakened to 6.6832 per dollar, its weakest since October 19, after the central bank set a weaker-than-expected daily fixing. The move followed the PBOC's decision to raise the foreign exchange reserve requirement ratio from 4% to 6%.
Beijing is slowing yuan appreciation, which tends to reduce the purchasing power of Chinese importers of US farm goods and feed ingredients at the margin. The effect on grain and feed prices is limited, so the move matters mainly for currency-linked trade flows.
After 362 past bearish macro events, Chinese Yuan (CNY per USD) moved a median -0.1% over 5 sessions (42% higher; middle half -0.4% to +0.1%), and -0.2% over 20.
