Michael Heise, chief economist of Allianz SE, says the ECB needs to assure financial markets that the deflation risks in the first half of 2015 are not all negative, as the declining price of oil adds to purchasing power in the eurozone economies. He points out that ECB needs to define price stability not as inflation of "nearly 2%" but as inflation of "below 2%," to take into account the impact of declining oil prices on inflation. His concern is about financial markets expecting strong quantitative easing program from the ECB in 2015.
