The rupee closed weaker on Friday , pressured by dollar demand linked to maturing non-deliverable forward positions and corporate hedging as global markets awaited a key U.S. Supreme Court ruling on trade tariffs. The currency closed at 90.1625 against the U.S. dollar, down 0.1% on the day but little changed week-on-week. Traders pointed to heightened dollar demand at the central bank's daily reference rate and hedging activity from companies, which weighed on the local unit on Friday. State-run banks were intermittently spotted offering dollars near the day's low for the rupee, which helped limit its losses, two traders said. The central bank stepped in firmly to shore up the currency earlier in the week, but traders said the rupee remains vulnerable without progress in U.S.-India trade talks, or a reversal in portfolio outflows. The dollar gained on Friday after data showed slower than expected U.S. jobs growth, suggesting the Federal Reserve could leave interest rates unchanged later this month. The dollar rose marginally across peer currencies as the data before paring those gains. The greenback was up 0.72% to 158 against the Japanese yen and was up 0.25% to 0.801 against the Swiss franc . The euro was down 0.22% against the dollar at $1.1633. The dollar index rose 0.27% to 99.14. Oil prices rose on Friday on concerns about potential disruption to Iran's output and uncertainty about supply from Venezuela. Brent futures were up 50 cents, or 0.8%, to $62.49 per barrel at 1359 GMT, while U.S. West Texas Intermediate (WTI) crude was up 51 cents, or 0.9%, to $58.27.......
