The single currency extended a period of declines against other counterparts on Tuesday, after a report from German Federal Statistical Office unveiled disappointing inflation data, reflecting weak domestic demand and underscoring challenge for the ECB to increase inflationary pressure in the region. Official report showed the Consumer Price Index in Europe's largest economy fell to 1.2% in October from the same period a year earlier, retreating from 1.4% a month earlier, and hitting the lowest since August 2010. On a monthly basis, CPI posted negative growth, falling 0.2% over the corresponding period. The main downside pressure came from price of mineral oil that fell 7%, while in contrary, electricity prices soared 11.5% annually.
