NEW YORK, Sept 9 (Reuters) - JPMorgan Chase

Co ( JPM )-CEO of investment banking Doug Petno said that investment

banking revenue will grow in low double digits for the third

quarter of this year.

Petno also told an investor conference on Tuesday that

markets revenue would grow in the high teens percentage rate for

the third quarter.

JPMorgan's ( JPM ) investment banking fees grew 7% to $2.5 billion

in the second quarter. That result surpassed its guidance in May

for a decline by a mid-teens percentage.

Investment banking activity was led by mergers and

acquisitions and debt underwriting.

Market turmoil from tariff announcements also propelled the

bank's trading revenue up 15% to $8.9 billion in the second

quarter, driven by gains in both fixed income and equities.

Shares were up 1.8% to $298.15 in midday trading.
