The Rupee opened weaker on Friday, with near-term sentiment titled bearish ahead of Federal Reserve Chair Jerome Powell's speech post market that may offer cues on the interest rate outlook. The rupee rose past the 87 per dollar mark in the last session before coming under pressure throughout the afternoon. The currency posted its biggest one-day percentage decline in a month, with traders attributing the drop to heavy dollar demand from oil companies and other importers. Before Thursday's decline, the rupee had been surprising markets, moving higher despite what most consider a challenging backdrop. The comment referred to the possibility of Washington imposing additional tariffs of up to 50% on Indian goods from August 27. The key will be whether Powell pushes back on the more than 80% probability priced in for a rate cut next month. While his recent comments have leaned hawkish, they preceded the weaker July jobs report. That might leave the dollar vulnerable after a steady but unspectacular rise in the past week. The euro last bought $1.1613, down 0.8% for the week, while sterling was steady at $1.3416, down nearly 1% for the week. The dollar index , which measures the U.S. currency against six rivals, was at 98.61, on course for a 0.7% rise in the week, snapping its two-week losing streak. The yen fetched 148.45 per dollar in early trading after core inflation in Japan slowed for a second straight month in July but stayed above the central bank's 2% target, keeping alive expectations for a rate hike in the coming month. The yen is on course for a weekly drop of over 0.8%, its biggest decline in a week since mid-July. The Australian dollar was little changed at $0.6425, set for a 1.2% drop for the week, while the New Zealand dollar eased a tad to $0.58145, on course for a 1.8% weekly decline, its biggest drop in more than four months. Oil prices were little changed on Friday but were on track to snap a two-week losing streak as hope for immediate peace between Russia and Ukraine dimmed, increasing the risk premium demanded by oil sellers. Brent crude futures were down 4 cents to $67.63 a barrel at 0052 GMT, while West Texas Intermediate (WTI) crude futures fell 1 cent to $63.51.......
