By Sruthi Shankar and Amal S
Jan 21 (Reuters) - European stocks lost steam heading into
the close on Thursday, weighed down by oil and real estate
shares, while the European Central Bank stuck to its monetary
policy but warned a surge in COVID-19 infections posed a risk to
the euro zone's recovery.
The pan-European STOXX 600 index .STOXX ended flat after
rising as much as 0.8% earlier in the session.
Energy majors BP BP.L , Royal Dutch Shell RDSa.L and
Total TOTF.PA each fell more than 2% as oil prices slipped
after industry data showed a surprise increase in U.S. crude
inventories. O/R
The ECB offered few surprises after it kept its policy
unchanged, while its president Christine Lagarde warned that a
new rise in cases and the ensuing restrictions to activity would
dampen activity in the near term and said the ECB was prepared
to provide even more support for the economy if needed.
"Lagarde touched upon the mixed positive and negative
developments but concluded that there were no reasons to change
the broader assessment from the December projections," Carsten
Brzeski, global head of macro at ING, wrote in a note.
Brzeski, however, noted the central bank's projection in
December of 0.6% GDP growth quarter-on-quarter in the first
quarter "is a tad optimistic."
Euro zone stocks .STOXXE came off session highs to close
0.1% lower with the euro strengthening against the dollar, while
euro zone banks .SX7E slid 0.6%.
European shares rallied to near 11-month highs earlier on
Thursday after as investors bet on major stimulus from new U.S.

fight climate change. Shares in wind turbine maker Vestas VWS.CO , renewable
energy group Siemens Gamesa SGREN.MC and offshore wind group
Orsted ORSTED.CO rose between 1.4% and 3.9%.
French shopping centre operators Unibail-Rodamco-Westfield
UNW.AS and Klepierre LOIM.PA lost 8.4% and 6.5%,
respectively, dragging down the real estate index .SX86P by
1.5%.
Tech stocks .SXTP jumped 1.6% as their U.S. peers rallied,
while British software maker Sage Group SGE.L jumped 4.9%
after posting higher quarterly recurring revenue. Spain's Bankinter BKT.MC gained 4.3% as it forecast higher
lending income and loan growth across its markets. Swiss online pharmacy chain Zur Rose Group AG ROSEG.S
climbed 8.9% after it posted full-year revenue above analysts'
expectations. Britain's IG IGG.L tumbled almost 9% after it announced
