The European Central Bank (ECB) purchased €12.46 billion of government and agency bonds under its quantitative-easing program last week.
The ECB said in its minutes of September meeting last week that it will raise the pace of its asset purchases from September to November 2015 "to prepare for the expected decline in market liquidity in December".
ECB'S asset buying programme is intended to run to September 2016.
The ECB bought €1.82 billion of covered bonds, and €244 million of asset-backed securities.
