Bank of Ireland expects to report a mid single-digit percentage increase in profit before tax and exceptional items for the six months to the end of September.
In a scheduled trading statement, Bank of Ireland said it expected interim profits to rise on the back of strong volume growth across the group.
The bank reported interim profit before tax and exceptional items of €642 million in 2003.
"We continue to position ourselves in each of our marketplaces to gain maximum benefit from the improving macro economic environment and to drive further profit growth in the future," chief executive Mr Brian Goggin said in a statement.
The group expects its net interest margin to decline by high teen basis points, as it flagged when presenting its year-end results because of current low interest rates and a change in the firm's funding mix to accommodate growth in assets.
