Plunging oil prices have substantially reduced Saudi revenues. With Brent prices averaging roughly $100 per barrel in 2014, Saudi oil exports of 6.31 million barrels per day would have generated roughly $631 million in revenues daily. In the first quarter, with Brent prices averaging $53.92, the same output would have generated roughly $340 million daily, $291 million less per day than oil at $100 per barrel.

The Kingdom of Saudi Arabia may suffer a financial crisis before winning the economic oil war with the United States if the oil prices remain at its current level. The Kingdom needs the oil price to be around $106 per barrel to maintain its economy.

Saudi Arabia is expected to raise prices for crude it sells to Asia in September due to a stronger Dubai benchmark, traders and analysts said on Monday, adding that the top oil exporter will be wary of a hike so big it would threaten its market share.

Saudi Arabia has signed a commitment to invest up to $10 billion in Russia, the Russian Direct Investment Fund said Monday.

The most significant development on the supply side in 2014 was undoubtedly the continuing revolution in US shale. The US recorded the largest increase in oil production in the world, becoming the first country ever to increase average annual production by at least 1 million barrels per day for three consecutive years.

Crude oil prices are still about half their value compared with a year ago, but the now prolonged slump is unfolding such that another rise could be on the horizon

As the United States raced over the past five years toward becoming a global petroleum powerhouse, the world's biggest oil exporter Saudi Arabia quietly seized a market milestone from America: the largest source of peak summer demand.

More than $100bn of spending on new projects by the world’s energy companies has been slowed, postponed or axed following the oil price plunge, evidence of the drastic industry action that will curb output in coming years.

The rebound in oil prices has wide-reaching implications. For one, it certainly affects the situation in Russia and the Ukraine. As the price of oil stabilizes, the Russian government has become more comfortable with its fiscal situation, despite the fact that low oil prices and Western sanctions have sunk the country into a recession that will likely last through next year.

As Saudi Arabia pumps more and more crude, creating a glut in global supplies, US producers recently have begun to curtail oil production as prices plummeted. The cost of production for US shale producers is significantly higher than for conventional production in Saudi Arabia and in other OPEC countries, which gives those producers an advantage at a time of sagging oil prices.
