Lower inflation resulting from falling oil prices could allow European policymakers to adopt more expansionary monetary policies, Credit Suisse said in a new report.

"The contribution to European inflation from energy is now likely to be lower. For the euro area, that could mean HICP [Harmonized Index of Consumer Prices] falls as low as 1 percent, later this year, and in the U.K., the near-term profile for CPI inflation should also be lower," wrote Credit Suisse analysts in a report on European economics, out on Thursday.
