The renminbi fell from 6.36 to 6.78 against the dollar, a drop of about 6.6%, in roughly two weeks between late April and early May. Drivers include large foreign bond outflows, importer and exporter hedging, US dollar strength from Fed tightening, and a weak yen that pushed the PBOC to shift to a weaker cross-rate policy.
The renminbi's depreciation raises the cost of dollar-priced imports for China and shifts the outlook for its feed purchases. Continued weakness keeps USD/CNY elevated and tends to weigh on commodity demand from China.
After 398 past bullish macro events, Chinese Yuan (CNY per USD) moved a median +0.0% over 5 sessions (56% higher; middle half -0.3% to +0.5%), and +0.0% over 20.
