Oil prices have began the trading week by climbing further as Saudi Arabia’s key 7 million barrel per day East-West pipeline remains off line after further strikes on the route and nearby facilities. In Asian trading, Brent November contracts on ICE Futures were $2.65 higher at $107.26 per barrel on Monday. But physical grades have soared far higher: Reports showed North Sea Ekofisk trading at $126/bbl and key Mideast spot grade Oman quoted at $135/bbl.
