As the Libyan government cracked down on protesters, Western oil companies including Eni and Repsol-YPF temporarily suspended oil production in the country. BP has started evacuating workers.
"The protests in Libya are the first to meaningfully put oil supplies at risk," Goldman Sachs said in a report.
Goldman, which is forecasting benchmark crude to rise to $103 within 12 months, said recent violent protests in Bahrain show that wealthy oil-rich Gulf states are also vulnerable to political upheaval.
"These recent developments in Libya and Bahrain increase the risks of major supply disruptions," it said.
The crisis in the Middle East and North Africa began in January with the overthrow of Tunisia ruler Ben Ali, spread to Egypt and the resignation of President Hosni Mubarak and has sparked protests in Yemen, Bahrain, Iran, Algeria, Morocco and Jordan.
Traders are watching closely protests in Iran, OPEC's second largest producer, and for signs of any unrest in Saudi Arabia, the world's biggest crude exporter. Analysts fear that further oil price spikes could fuel inflation, undermining consumer spending and global economic growth.
"Saudi Arabia, itself an authoritarian state, now finds itself surrounded by countries in the throes of revolution," energy analyst Richard Soultanian of NUS Consulting said.
"Should the current situation continue to deteriorate, it has the potential to not only roil the energy markets but also upend the nascent and accelerated recoveries in developed and emerging markets."
Some observers expect a return to the sharp fluctuations of oil prices seen in the 1970s.
"Today's situation is reminiscent of the 1970s," said Anthony Michael Sabino, a professor at St. John's University's college of business. "The price of oil will now jump in direct relation to one of its oldest barometers â political tension in the Middle East."
"Expect nothing but a roller coaster ride for a few weeks, if not months."
Also looming over markets is the impact of higher oil prices on the still fragile economic recovery in many countries.
"While an interruption to Libya crude production would be definitely bullish oil prices ... the economic recovery can be put in question if oil prices were to return to the summer 2008 levels," said Olivier Jakob of Petromatrix in Switzerland. "This remains for now a headline market until we can better assess the amount of crude supply disruption in Libya and the response from the IEA and Saudi Arabia."
Saudi Arabia's oil minister Ali Naimi was quoted as saying that his country's production capacity of 12.5 million barrels per day could help "compensate for any shortage in international supplies." Saudi Arabia currently produces around 8 million barrels per day.
