Global markets have been in turmoil since the start of the year, with stocks and commodities prices reeling, eroding inflation and making central banks increasingly dovish – a trend that could continue with more weak economic data. China, a focus of much of the recent market concern, released foreign reserves data on Sunday which showed the central bank dumped dollars to defend the yuan and prevent an increase in capital outflows. The country’s foreign reserves fell $99.5 billion to $3.23 trillion in January, the lowest level since May 2012, central bank data showed.
