MUMBAI (Reuters) - The rupee is seen rising on Friday, boosted by gains in Asian equities and the euro, after the Indian unit ended weak for eight consecutive sessions. * Persistent dollar demand from domestic oil companies for import payments could limit rupee's rise, traders said. * June industrial output data around 0530 GMT will also be watched for cues on growth and interest rates, traders said. * At 0246 GMT, the MSCI index of Asian stocks ex-Japan was up 1.32 percent and the Nifty India futures traded in Singapore were 0.89 percent higher, suggesting a strong opening to local equities. * The euro was at $1.4204 from $1.4122 at end of local forex trade, while the index of the dollar against six major currencies was up 0.01 percent at 74.684 points, but lower from 74.982 points previously. * Forward premia will be closed watched for cues on rupee moves as premia have fallen sharply since Wednesday due to a spot dollar shortage created by local oil refiners' dollar purchases, they said. * The partially convertible rupee is expected to open around 45.20 per dollar and move in a band of 45.10 to 45.40, traders said. * It had ended 0.4 percent weaker at 45.4050/1450 per dollar on Thursday.
