Bloomberg reported on Tuesday that the European Central Bank (ECB) would probably wind down its 80 billion euro ($90 billion) monthly bond purchases gradually before ending its quantitative easing program, citing unnamed officials at euro zone countries' central banks.

Ric Spooner, chief market analyst at CMC Markets in Sydney, wrote that international bond markets "appear to be at a stage where nervousness about the prospect of central bank stimulus ultimately ending is outweighing the positive impacts of any near term moves to temporarily extend that stimulus."
