PBOC sets USD/ CNY reference rate for today at 7.0727 (vs. yesterday at 7.0752)

People’s Bank of China 
In OMOs – inject 60bn yuan via 7 day RRs ( no maturities today thus net +60bn)
That’s a total of 510bn in the past three days. PBOC adding liquidity ahead of tax payments due is the story apparently.
