Today is the biggest day of the week in terms of major events that could influence the FOREX market. The ECB will meet on today and it could decide to announce an extension to its QE program beyond March of next year. Given the rise in certain peripheral yields lately as well as inflation remaining well-contained (it rose to only 0.6% year-on-year during November), an extension of QE would probably be the most prudent decision for the European Central Bank to make.
The European Central Bank, which has announced a stimulus program back in March 2015 and running to March 2017, or "as long as it's needed," is expected to announce an extension, of at least six months, but to keep the amount of bonds' purchases and rates on hold. Anything less than that could be read by the market that the ECB is preparing to tighten economic conditions, and will result in the EUR rallying sharply against its major rivals.
