Unlike the regimes in Tunisia and Egypt, the Qaddafi regime has proven itself to be able and willing to use brutal military force against protesters. Depite this, the opposition seems to have taken control over eastern Libya, while the Qaddafi regime seems to remain in control for now over the western parts , including the capital Tripoli.
The issue of which side will prevail remains uncertain. However, regardless of who ultimately wins, the economic outcome for the outside world seems to be quite clear:
1) In the short-term, Libya's oil exports will be cut off, causing a short-term increase in the price of oil.
2) In the long-term, Libya's oil exports will likely resume, meaning that there won't be much long-term economic effects of this.
