The Reserve Bank of India (RBI) on Wednesday raised the key interest rate by 50 basis points, the second increase in five weeks, to rein in the rise in prices that it saw continuing to hurt consumers in the near term.
The rate hike comes on the back of a 40 bps increase by the RBI at an unscheduled meeting on May 4.
''Major crosses remain under pressure following broader strength in the dollar. The focus will be on the European Central Bank (ECB) policy statement and hawkish comments could restrict major weakness for the Euro,'' Somaiya said, adding, ''We expect the USDINR to trade sideways and quote in the range of 77.40 and 78.05.''
