Investing.com - The euro pushed lower against the U.S. dollar on Tuesday, as markets were jittery ahead of the European Central Bank's monthly policy meeting this week amid growing expectations for additional easing measures.

EUR/USD hit 1.2399 during U.S. morning trade, the pair's lowest since November 24; the pair subsequently consolidated at 1.2403, declining 0.54%.

The pair was likely to find support at 1.2357, the low of November 24 and resistance at 1.2524, the high of November 27.

The euro remained under pressure after data on Friday showed that the annual rate of euro area inflation slowed to a five year low of 0.3% last month, down from 0.4% in October.

The weak data added to pressure on the ECB to step up measures to spur growth and stave off the threat of deflation ahead of its upcoming policy meeting on Thursday.

Sentiment on the single currency also remained vulnerable after data on Monday showed that the euro zone’s manufacturing purchasing managers' index slowed to 50.1 from a preliminary reading of 50.4 last month, just barely above the 50 level separating growth from contraction.
