10 things you need to know before the opening bell

Here is what you need to know.

The IEA thinks oil prices could've bottomed. Reuters reports that the International Energy Agency says there are signs energy prices might have put in their lows, as output is falling faster than expected and the supply from Iran is having a smaller impact than expected. In its latest forecast, the IEA projects that non-OPEC output will fall by 750,000 barrels a day in 2016; it previously forecast a drop of 600,000 barrels a day. The US alone will see a drop in production of 530,000 barrels a day, the IEA says. Crude oil is up 2.2% at 38.66 a barrel.

The UK's trade deficit with the EU hit a record. Data from the Office of National Statistics showed that the UK's trade deficit widened to £10.3 billion ($14.7 billion) in January, in line with estimates. Notable is that the UK's trade deficit with the European Union expanded to £8.1 billion for the month and £23 billion over the past three months, both records according to Bloomberg. This will surely be a talking point of those campaigning for a British exit from the European Union at the June 23 referendum. The British pound is stronger by 0.2% at 1.4303.

European bank stocks are surging. On Thursday the European Central Bank lowered its main refinancing rate to zero and cut its deposit rate to -0.40% while increasing its quantitative-easing program to €80 billion a month. The announcement has sparked a massive rally in European financials. Italian banks are among the top performers on the day, as UniCredit and Intesa Sanpaolo are both higher by more than 5%.

Pimco thinks the ECB might eventually buy blue-chip stocks. The markets' reaction to the ECB rate cuts had many market participants discussing the possibility that the ECB was "out of ammo." But Pimco managing director and portfolio manager Adam Bosomworth doesn't think so. In an opinion piece written overnight, he suggested that the central bank would use asset purchases to stimulate the economy and that the purchase of blue-chip stocks was "not a far step away."

Deutsche Bank warns that Q1 will be rough for banks. Volatile financial markets will pose a challenge for the entire banking sector in the first quarter, Deutsche Bank warns. This seems to jive with comments from other investment banks like JPMorgan and Citigroup, which have previously warned about tough conditions. "Deutsche Bank is no exception to this," CEO John Cryan said in the company's annual report, which was published Friday. "Nonetheless, in this period of market turbulence, Deutsche Bank remains very solid."

Singapore is the most expensive city to live in. On Thursday the Economist Intelligence Unit released its report titled "Worldwide Cost of Living." It showed that Singapore was the most expensive city in the world to live in when taking into account factors including food costs, fuel costs, and salaries. Rounding out the top three were Zurich, Switzerland, and Hong Kong. US cities making the top 10 were New York (No. 7) and Los Angeles (No. 10).

Short seller Andrew Left has a new target. Noted short seller Andrew Left, whose recent targets include Valeant and Mobileye, has a new short. On Thursday he released a 21-page report on the tech company j2 Global. Left slapped a $26 target on the name, saying it had "hit a wall." The stock finished Thursday's session down close to 20% at $56.90 a share.
