Prices of oil futures are gaining more than 4.5% so far today amid increasing concerns over the crisis in Ukraine and recent strikes on Saudi's oil facilities. As Russia's army is encircling the capital and intensifying military operations, Europe and the US are getting ready to impose additional sanctions, possibly a ban on Russian oil imports, a situation that kills all hopes of peace talks. In addition, this morning, Saudi Arabia, the world's second-largest export of oil, called on the international community to do more to counter Houthi strikes on the kingdom, warning that they could disrupt global energy supplies. It remains to be seen whether the Europeans will take the plunge, but in the meantime, as the situation worsens, oil prices see a lot of upward risks.
