While Brits were busy voting to Leave the EU, and the world watched, China continued to quietly devalue their currency, the renminbi/yuan. Why are they doing this? To spur exports of goods to the USA, just like every other nation on earth. To be sure, these don;t look like big percentage moves because the yuan is theoretically "fixed" to the US$, however, remember what happened when they started moving further from their "peg" (to the US$) last August...mayhem. The fact they continue to devalue the yuan is not a good sign for global inflation and economic growth prospects.
(Higher is stronger US$ and weaker yuan)
