Still, the yuan’s bounce was modest and the risk-sensitive Australian and New Zealand dollars both fell around 0.3% as sentiment remained fragile.

“Many people’s constructive view on the renminbi … was partly premised on continued foreign capital flows into the domestic financial markets,” RBC Capital Markets analysts wrote.

“The risk from equity outflows will dominate in the near term.”
