The European Union’s embargo on most Russian oil imports could deliver a fresh jolt to the world economy, propelling a realignment of global energy trading that leaves Russia economically weaker, gives China and India bargaining power and enriches producers like Saudi Arabia.

Europe, the United States and much of the rest of the world could suffer because oil prices, which have been marching higher for months, could climb further as Europe buys energy from more distant suppliers. European companies will have to scour the world for the grades of oil that its refineries can process as easily as Russian oil. There could even be sporadic shortages of certain fuels like diesel, which is crucial for trucks and agricultural equipment.

In effect, Europe is trading one unpredictable oil supplier — Russia — for unstable exporters in the Middle East.
