Meanwhile, the economic data from the Eurozone was better than expected. Market research group GfK released its consumer confidence index for Germany on Wednesday. German Gfk consumer confidence index remained unchanged at 9.4 in February, beating expectations for a drop to 9.3.

"The consumer climate has therefore been able to withstand the recent growth in risks it is facing. However, in the next few months the escalating terror threat and the rising fears among certain groups of the population that Germany could eventually become overstretched by the persistently high influx of refugees and asylum seekers may cause consumer confidence to wane in the long term. In turn, this would have a lasting impact on the consumer climate," Gfk noted.

"Last year was a strong year for household borrowing. There was a 6% rise in mortgage borrowing compared to 2014 and consumer credit expanded at more than 5% annually within an overall unsecured market which is growing at nearly 10% annually," the chief economist at the BBA, Richard Woolhouse, said.

The Nationwide Building Society released its house prices data for the U.K. on Wednesday. UK house prices were up 0.3% in January, missing expectations for a 0.6% rise, after a 0.8% increase in December.

On a yearly basis, house prices fell to 4.4% in January from 4.5% in December. Analysts had expected house prices to rise by 4.7%.

"As we look ahead, the risks are skewed towards a modest acceleration in house price growth, at least at the national level, Robert Gardner, said.
