SHANGHAI, June 14 (Reuters) - Copper prices inched up on Friday and were on track to post their first weekly rise in seven weeks, helped by reports that major central banks are poised to inject liquidity should the results of weekend elections in Greece unleash havoc on financial markets. But investors remained cautious as disappointing jobs data from the United States added to fears that recovery in the world's largest economy may be slowing. FUNDAMENTALS * Three-month copper on the London Metal Exchange had risen 0.5 percent to $7,456 a tonne by 0111 GMT, on course for its third consecutive daily rise. * The most-active September copper contract on the Shanghai Futures Exchange gained 0.8 percent to 54,540 yuan ($8,600) a tonne, set for its second straight daily climb. * Central banks from major economies stand ready to take steps to stabilize financial markets by providing liquidity and preventing a credit squeeze if it looks like Greece could leave the euro zone after elections on Sunday, G20 officials told Reuters.
