Oil interrupted a eight-day winning streak on growing worries that European governments are not responding adequately to their debt problems. Prices slipped from the two-month high they posted yesterday as yields on the benchmark ten-year Spainish bond marked a new high on the final approval of the bailout money from the Eurozone. Crude for August delivery declined $1.22, or 1.3%, to trade at $91.44 a barrel on the NYME. Oil finished at the highest price since May 16 on Thursday adding to the gains it had posted in the previous seven sessions. Prices are down 7.5% for 2012, but they have risen 5% for the week. Brent oil for September slipped 96 cents, or 0.9%, to $106.84 a barrel on the London-based ICE Futures Europe exchange.
