Europe ends mostly lower despite oil jump; Seadrill, miners soar

European markets finished mostly in the red on Monday despite a strong recovery in oil prices and mining stocks as investors digested the latest corporate news and fresh economic targets from China.

The pan-European STOXX 600 index ended down off some 0.25 percent, with most sectors closing in the red.

London's FTSE, France's CAC and Germany's DAX were all off between 0.3 and 0.5 percent by Monday's close.

In markets overseas, Asia finished mixed, following China's new economic targets, while U.S. stocks struggled for gains at Europe's close as investors awaited indications on monetary policy from across the globe.

Brent at $40; Seadrill surges 60%

The oil price continued its march higher on Monday with Brent crude hitting a 2016 high of above $40 during trade, after Genscape reported a smaller build in stockpiles at the Cushing, Oklahoma delivery hub for U.S. crude, according to Reuters.

At Europe's close, both Brent and U.S. crude were up 3.5 percent, with Brent hovering at $40.13 per barrel, while U.S. crude was trading around $37.23. This sharp boost in prices drove stocks higher, with Saipem and Subsea 7 both closing sharply higher, up over 7 and 3 percent respectively.

Shares in offshore driller Seadrill led European benchmarks, surging over 60 percent, after its CEO said short-sellers were starting to panic at the possibility Seadrill's refinancing plan would succeed, Reuters reported.

Most stocks recovered from earlier losses, however BP closed in the red.

Banks under pressure

Banks were once again in focus on Monday, with the sector off 1 percent by the close. Germany's Commerzbank closed slightly higher, after it named retail banking head Martin Zielke as its next chief executive from May 1.

Several Italian banks came under pressure on Monday on continued concern over the portfolio of non-performing loans held by the lenders. The likes of Banco Popolare and Intesa Sanpaolo were both closing trade sharply lower.

Analysts said that the low inflation environment in Europe is hurting the banks, but overall the sector looks cheap for investors.

"The difficult here is that margins are continuing to be squeezed. You're in a low inflation environment, it's not a solvency risk, it's just more a malaise in terms of a low earnings outlook and the potential risks around that," Bill O'Neill, head of the U.K. investment office at UBS Wealth Management, told CNBC.

"One way or another, the sector is cheap."
