Standard Chartered said on Wednesday that first-half net profit rose to a record high, with strong overall revenue growth outpacing an increase in impairments, the strengthening dollar and weakness in India.

The Asia-focused bank's net profit for the six months ended June 30 rose 12% to $2.81bn from $2.52bn in the same period in 2011. Revenue increased to $9.51bn from $8.76bn a year earlier as the bank continued to gain market share in emerging countries. Bad debt charges ticked up across the group as the bank ramped up unsecured lending.
